The Effect of Authentic Input Devices on Computer Game Immersion Daniel Pietschmann, Georg Valtin, Peter Ohler Chair of Media Psychology and Media Sociology, University of Technology Chemnitz Abstract A key question in the field of computer game studies is the user experience during the gameplay. One of the main factors influencing this experience is the control mechanism that players use to interact with the game system. With the launch of the Wii Console in 2006, Nintendo introduced an innovative concept of controlling computer games that allows users to manipulate and to interact with game elements on the screen by moving and pointing the input device. The usage of game controllers with a high degree of perceptual closeness should influence the gaming experience in such a manner that the degree of immersion is higher compared to the usage of a regular gamepad which eventually leads to a higher entertainment value. We conducted a study to examine the influence of the input device players use to control a game on the immersion and perceived entertainment value. The results of the study show, in accordance with our assumptions, that a more authentic input device results in a higher degree of immersion and entertainment value. Keywords: immersion, input devices, user experience, Wii, study, entertainment value Introduction: Computer Game Immersion and User Experiences Computer games1 are nowadays considered as one of the most important forms of entertainment. What has been despised as a nerdy waste of time some years ago has meanwhile been developed into a major phenomenon with a strong economy and a noticeable cultural impact. The increasing role of computer games raised the interest of many researchers that use a wide array of approaches and methods to scientifically explain the phenomenon. A key question in the field of computer game studies is the user experience during the gameplay, thus the experience resulting of the interaction between the player and the computer game. This has proven to be a difficult subject, because the rapid development of gaming hardware and software constantly alters the user experience. One of the latest major developments is the increased usage of new input devices. With the launch of the Wii console in 2006, Nintendo introduced an innovative concept of controlling computer games. The so called Wii-Remote and Nunchuk have a built-in motion sensing capability that allows the player to manipulate and to interact with computer game elements seen on the screen by moving and pointing the controllers.2 Most games for the Nintendo Wii 1 Computer games and video games are used synonymously in this paper, since the differences between the two terms are merely technical in nature. However, the term “computer games” better emphasizes the use of computer based hardware, whereas “video games” refer to the visual presentation on a video monitor. 2 Basically, the Wii-Controllers use a build-in accelerometer and optical sensor-technology, for details cf. e.g. Witzmann 2007. have been designed in a way to fully support the new control mechanism. For example, playing a bowling game requires moving the arm and hand similar to rolling a real bowling ball while holding the controller. Likewise, a tennis game requires holding the controller like a racquet and performing forehand and backhand swings.3 Without much doubt, this new way of controlling computer games has a deep impact on the player experience. To be more specific: In our opinion, the entertainment value (“Spielspaß”) of computer games is generally increased by the usage of controllers that provide a more realistic (or to be precise: a more authentic) experience. In this paper, we substantiate that assumption in consideration of the relevant theories and discuss the results of an empirical study that was conducted to confirm it. Researchers suggested several concepts and determinants to comprehend and to explain the user experience during the act of playing computer games, e.g. interactivity, effectance4, self-efficacy, control, presence and immersion (e.g. Ryan 2001, Zimmerman 2004, Klimmt 2006, Tamborini/Skalski 2006, Murray 1997, McMahan 2003). Thereof, immersion is one of the most discussed terms and topics in the field of computer game studies with many different approaches, e.g. from literature studies (e.g. Murray 1997) or presence research (e.g. Slater/Wilbur 1997). As a result of the heterogeneous approaches there is a lack of a generally accepted definition of the term “Immersion” (cf. Pietschmann 2009: 76). In our understanding, immersion has to be considered as a psychological state of the user, similar to concepts like flow (cf. Csikszentmihalyi 1975/2005), presence (cf. Tamborini/Skalski 2006) and cognitive absorption (Agarwal/Karahanna 2000). Several definitions of immersion relate to focusing ones attention “on something other than the immediate surrounding reality” and mean, that the user is “captured by and experience[s] a story and its world, shutting out the ‘real’ world around [her]” (Gander 1999:1).5 Independent of the approaches to conceptualize immersion, researchers agree on the existence of different forms of immersion that contribute to the construct of immersion as a whole. Examples include visual immersion (e.g. Held/Durlach 1992), social immersion, temporal immersion, emotional immersion or sensomotoric immersion (e.g. Ermi/Mäyrä 2005). The last-mentioned is the most relevant form of immersion for our study. Björk and Holopainen define sensomotoric immersion as “the result of feedback loops between repetitious movements players make to perform actions in the game and the sensory output of the game” (Björk/Holopainen 2004 :206). Accordingly, sensomotoric immersion is the part of immersion that occurs as the consequence of the player interacting with the (game) system interface. Considering this as one of the most fundamental parts of computer games, sensoric immersion seems to be a core experience during gameplay episodes. It’s closely linked to explicit interactivity (cf. Zimmerman 2004: 158) and the resulting experience of selfefficacy (cf. Klimmt 2006: 76). Ermi and Mäyrä (2005) suggest “sensory immersion” (synonymous to visual immersion and in their terms part of sensomotoric immersion) as one of three key dimensions of the gameplay experience. According to their understanding, sensory immersion is a quality characteristic of the media: “Large screens close to player’s face and powerful sounds easily overpower the sensory information coming from the real 3 There are lots of expansions and accessories that can be attached to the default controller to give the gaming experience an even more realistic touch. Available expansions and accessories include golf clubs, tennis racquets, guns and swords. 4 Effectance means the perceived influence on the game world. For a comprehensive discussion of the term immersion and its various types see Pietschmann (2009) 5 world, and the player becomes entirely focused in the game world and its stimuli” (Ermi/Mäyrä 2005: 7). Sensomotoric immersion puts the focus on the sensory perception as well as the player’s body movement during the gaming experience. The well-established Virtual Reality-Research understands sensorimotor functions (“Sensomotorik”) as the interactions of the multiple human sensory systems (cf. e.g. Steuer 1992, Heers 2005). One of the main goals of virtual reality technology is to achieve a high level of authenticity by an adequate stimulation the human sensory systems (cf. Held/Durlach 1992), including visual, auditory, tactile, olfactory and vestibular sensory stimuli.6 It is generally assumed that a better interplay of the multiple stimuli leads to a higher degree of authenticity, and this, in turn, causes the state of sensomotoric immersion. We agree with this argumentation. Therefore, sensomotoric immersion relates to the interaction of perception and bodily reactions to the perceived stimuli. Given the fact that both concepts are refering to a psychological state during (digital) media usage, immersion and presence are often used in similar contexts or even synonymously. Whereas the term presence is usually associated with “serious” virtual reality environments, “immersion” was applied accordingly from literature to digital entertainment. Both concepts have been accounted for in our study. Several methods exist to measure immersion and presence empirically. Especially in the presence research, many instruments have been developed to proof the concept in scientific studies. Currently available methods can be categorized in subjective (questionnaires, online-ratings or qualitative explanatory discussions/interviews) and objective (behavioural, physio-psychological or neurological) measurements. For a comprehensive overview over 69 different methods see Van Baren and IJsselsteijn (2004). Studies for evaluating immersion also range from qualitative approaches (e.g. Brown/Cairns 2004), which identified important barriers and prerequisites of computer game immersion to quantitative research, combing subjective and physio-psychological (e.g. eye-tracking) measures (e.g. Jennet/Cox/Cairns/Dhoparee/Epps/Tijs 2008). Study: Sensomotoric Immersion As computer games can be understood as a special form of virtual reality, it is reasonable to apply the discussed theoretical principles: More realistic/authentic game interfaces (or symbolic media systems in general) with ways of interaction drawn from life conciliate more authentic and more “believable” stimuli and thus sensomotoric immersion. Other types of immersion (e.g. emotional, social or narrative immersion) moderate the effect of sensomotoric immersion, as they can intensify or weaken the immersive experience as a whole. The more authentic the perceived interaction between the player and game system, the higher is the sensomotoric immersion of the player. A higher degree of sensomotoric immersion increases the fun and entertainment value of computer games. Let’s clarify this by the example of playing a car racing game. If the player controls her vehicle with the keyboard, the sensomotoric immersion should be very low, because she uses a rather abstract input device for an activity that is performed completely different in the real world. The procedure of driving a car is being reduced to simple keystrokes for accelerating, breaking and steering, while only the visual and auditory sensory systems are being stimulated in a realistic way – given the fact that actual racing games provide simulation-like 6 Not all of these sensoric stimuli must be present to cause sensomotoric immersion. graphics and sounds. If the player uses a steering wheel and pedals instead of the keyboard, the gaming experience changes significantly. In this given case, the tactile sensory system is also stimulated in a realistic way, since using the steering wheel and pedals to control a car appears natural and authentic. Although this is of course not a perfect simulation of driving a racing car (e.g. there are no acceleration forces), the more authentic control is resulting in a higher degree of sensomotoric immersion.7 A quantitative study was conducted to understand the user experience of sensomotoric immersion during a play session using the Nintendo Wii console. The aim of the study was to clarify how the input device (authentic/realistic input versus arbitrary/abstract input) is related to immersion, presence and perceived entertainment value. Several existing questionnaires were used to measure immersion and presence after the game session. We used different questionnaires, because an important question regarding the relationship between presence and immersion is not answered yet: Are the experiences of presence and immersion in computer games two individual psychological states of mind, or different interpretations of the same concept? By measuring both concepts, we were able to compare them directly. Although various game relevant factors contribute to both concepts as a whole (e.g. visual perspective, narrative, game tasks, audiovisual quality, single- or multiplayer, etc.), our focus was on the input devices: The experimental group was given an (authentic) Wii-Remote controller with a tennis racquet add-on to play a tennis computer game, whereas the control group had to play the same game with a classic gamepad controller. No other changes were made, thus the only difference in both groups’ game session was the input device and the potential degree of sensomotoric immersion, respectively. In this paper we address the three major hypotheses and their implications. H1: Users perceive a higher degree of immersion and presence when using an authentic game controller than when using an abstract gamepad controller. According to their practical gaming experience, we divided our subjects into the groups “nongamer”, “casual gamer”, and “regular gamer”. Based on Schema Theory (cf. e.g. Smith/Queller 2001), we suspected that experienced players grew so accustomed to playing computer games with a gamepad controller, that they don’t need to think much about controls (construct/create new schemes) while playing. For them, playing with a gamepad is the “natural” way to interact with a console game. They focus their attention not on controlling the game, but on the game (and the content) itself. Inexperienced players, however, need to learn how to interact with the game before playing. Their attention is more likely to be focused on the controls instead of the game’s content, as their cognitive system has no (or not enough) pre-existing schemes to operate the interaction properly. If inexperienced players could draw on a way of interaction with the game that they know from the real-world, they would not need (completely) new schemes, but use existing schemes instead. When playing a computer game with an authentic input device based on prior real-world experiences, they should be more able to focus on the game content and thus potentially experience a higher degree of immersion or presence. Inexperienced players should therefore benefit greatly from the use of an authentic input device, because they don’t need to learn an arbitrary way of interacting with the game and instead use a way they are already familiar with. 7 Of course only under the condition that steering the car matches the expectations of the user. If the car would understeer permanently or if pushing the throttle pedal would decelerate the vehicle, there would be no authenticity and therefore low sensoric immersion. H2: Experienced users do not benefit as much from authentic input devices in terms of immersion and presence as casual players do. The amount of real-world experience with the given task varies individually. In this study, the subjects had to play a tennis computer game, so the degree of experience with real-world tennis was also taken into consideration (dichotomously: low/high experience). Players who never played real-world tennis before are considered to have other expectations towards the interaction with the game than regular tennis players have. For the latter, the game has to meet a high demand in realism and simulation accuracy; otherwise the players would feel their interaction to be restricted. If they cannot use familiar movements from their practical real-world experience in the game, their sense of immersion or presence could be hindered. Inexperienced real-world tennis players, however, only base their expectations on the observation of tennis players in the real world or the media. This usually leads to a lower demand on simulation accuracy. In general, the perceived immersion should be higher for real-world tennis players, if the game simulates tennis-playing accurately. H3: Users with experience in real-world tennis score higher on immersion and presence when using an authentic input device than users without real-world tennis experience. Methodology Participants (N=136; male N=64; female N=72) were recruited through an opportunity sample via online advertisement. Their ages ranged from 12 to 74 years (average: 24,15 years; SD=7,91). 22% of the participants were non-gamers, 41% casual gamers and 37% regular gamers. The study was conducted in a game lab at Chemnitz University of Technology, using a darkened room with much space to move. The game console was connected to a video projector using a big (several meters) projection screen and surround sound system to minimize distractions and to provide optimal conditions for the formation of sensory immersion. All subjects were asked to play a tennis game on the Nintendo Wii console, either with a gamepad or a tennis racquet controller (see Fig. 1). We choose the game Sega Superstar Tennis (Sega Enterprises 2008) for the study, a game that was unknown to all participants (see Fig. 2). Hence, possible effects due to prior game experience could be ruled out. A tennis game was chosen because – unlike narrative computer games (e.g. The Legend of Zelda: Ocarina of Time, Nintendo 1998, which offers complex narrative immersion types) or MMOGs (e.g. World of WarCraft, Blizzard Entertainment 2004, complex social immersion types) – sports games usually don’t mix several complex types of immersion and focus on sensomotoric immersion in general or audiovisual in particular. Using a tennis game allowed us to easily separate sensomotoric immersion from other types of immersion. Furthermore, tennis being a popular sport, there were many games for the Wii console to choose from. Billiard, Golf or Bowling were also considered but had to be dismissed as most of these games varied too much in quality and complexity and furthermore did not sufficiently support multiple input devices. Although Wii Sports Billiard uses very authentic input, it’s not playable with a gamepad. Other tennis games considered were the Tennis game of Wii Sports (Nintendo 2005), Top Spin 3 (2k Shanghai 2008) or Rockstar Games presents Table Tennis (Rockstar Games 2007). They were deemed either too complicated, required too much practice time or did not support different controller devices. Sega Superstar Tennis scored reviews with an average (meta) score of 71%. It is suitable for beginners and relies on relatively simple game mechanics, thus making it enjoyable not only for the hardcore, but also for casual gamers. The study is based on a between-subjects design: The participants were assigned randomly to play with the classic gamepad or Wii-Remote tennis controller as independent variable. Before the game session, each subject had to fill out a questionnaire to collect demographic information and assess real-world tennis experience as well as general gaming experience. The latter contained questions regarding for example the playing time per week and the platforms used for gaming. In addition, participants had to complete the Immersive Tendencies Questionnaire (Witmer/Singer 1998), which has not been evaluated further for this paper. Fig. 1: Input devices used for the study Fig. 2: Screenshot from the game Sega Superstar Tennis (Sega Enterprises 2008) Each game session lasted about 20 minutes, including a training session with an instructor to get used to the game and the controls. After the game session, each participant had to complete a questionnaire that comprised translated versions8 of two questionnaires used in other studies (Immersion Questionnaire [IQ] from Jennet et al. 2008; Presence Questionnaire [PQ] from Witmer/Singer 1998).9 The items consisted of questions or statements that had to be rated on a 5-point Likert-Scale. Fig. 3 and Fig. 4 show sample items used for each category of both PQ und IQ. Also, further demographic information was gathered, such as participants’ game experience, real-world tennis experience, occupation, or level of education. The factorial structures of the immersion and presence questionnaires were validated using a factor analysis (principal axis factoring) which confirmed the factors reported in the original studies: The items of the PQ constitute the factors “involvement”, “interface quality”, “adaption/immersion”, and “visual fidelity”, whereas the IQ-items accumulate to “motivation/fun”, “real world dissociation”, “achievement”, “cognitive involvement”, and “challenge”. The data of the study were analyzed, using statistical procedures in SPSS.

The results of the study confirm H1: The use of the authentic game controller led to a significant increase of perceived immersion (two-sample t-test, t=3.39, 134 d.f., p < 0.001) and presence (two-sample t-test, t=2.84, 134 d.f., p < 0.005). The average amount of immersion and presence measured was higher in players using the authentic game controller. As the only difference between the experimental (N=63) and the control group (N=64) was the usage of differing input devices – and thus, the potentially amount of sensomotoric immersion – the differences measured in immersion and presence can only be attributed to differences in perceived sensomotoric immersion DISCUSSION?. This could be traced back to several factors, such as “visual fidelity” (Mann-Whitney-U-test, U= 1546.0, p < 0.001), “involvement” (Mann-Whitney-U-test, U= 1393.0, p < 0.0001), and “cognitive involvement” (Mann-Whitney-U-test, U= 1660.0, p < 0.005). No differences were found between groups regarding the factors “achievement” and “dissociation of the real world”. Perceived “challenge” was only marginally significantly higher, when using authentic input devices instead of the classic controller (Mann-Whitney-U-test. U=1909 p= 0.056). The factor “motivation/fun” however increased significantly when using the authentic tennis controller (Mann-Whitney-U-test, U= 1680.5, p < 0.01). The results did not support H2: Just like casual gamers, the experienced regular gamers also scored higher on immersion (two-sample t-test, t=2.15, 48 d.f., p < 0.05) when using the tennis controller instead of the gamepad, but not in presence. Regular gamers using the authentic input device also scored significantly higher on factors “involvement” (MannWhitney-U-test, U=173.5, p < 0.01) and “cognitive involvement” (Mann-Whitney-U-test, U=98.5, p < 0.01) in comparison to non-gamers and casual gamers. Surprisingly, unlike the group of regular gamers, there were no statistically significant differences in the immersion and presence scores when using different input devices in the non-gamers and casual gamers group in detail. Although just missing a statistical significance in the group of casual gamers (immersion score: p= 0.07; presence score: p=0.06) NOT CLEAR!, the only statistical relevant differences were the scores of “visual fidelity” (Mann-Whitney-U-test, U=56.5, p < 0.03) and “challenge” (Mann-Whitney-U-test, U=56.6, p < 0.02) for non-gamers and “involvement” (Mann-Whitney-U-test, U=232.4, p < 0.01) in terms of input devices. The results supported H3: When using the tennis racquet controller, players with real-world experience in tennis showed higher scores inimmersion (two-sample t-test, t=3.0, p < 0.01) and presence (two-sample t-test, t=3.0, p < 0.005) than players without experience. Discussion Our study has shown that the usage of an authentic input controller considerably changes the gaming experience or, to be more precise, enhances the gaming experience. While the overall scores of immersion and presence fully support H1, it is worthwhile discussing some factors in detail. According to theoretical considerations regarding the schema theory, the usage of the authentic input device should cause the player to fall back on existing schemes having more cognitive resources available for the actual gameplay. This has been confirmed by the factors “visual fidelity”, “involvement” and “cognitive involvement” that scored significantly higher in the experimental group. The usage of the authentic controller is more natural, so that the game content gets the full attention of the player: The player is absorbing the audiovisual stimuli to a higher degree, and therefore s/he is more involved in the gameplay. The significantly higher rating of the factor “motivation/fun” when using the authentic controller leads to the conclusion, that it enables users to experience more fun while playing the game, whereas the interdependence between immersion and fun has yet to be determined. Since previous computer game studies have been unable to agree on a theoretical model that can fully explain the entertainment value of computer games, we can only intepret the underlying causality. From a media psychology point of view, a possible explanation can be found in the model suggested by Klimmt (2006). This model explains the entertainment value of computer games as the result of three mechanisms that constitute the gaming experience: self-efficiacy, complex challenges in combination with narrative information, and simulated lifelike experience. A higher degree of (sensomotoric) immersion would increase the self-efficiacy as well as the lifelike experience (which in our case can be described as the player’s feeling of actually playing tennis). In further studies, we want to confirm the results of this study with various other game types. Those studies can also contribute to the empirical validation of Klimmt’s model, because the use of different controller types is a valid method to manipulate the self-efficiacy. Also, the long-term effects of playing with the authentic controller needs to be researched, since one could argue that the user experience of a higher entertainment value could also be moderated by the fascination of using an innovative control method and the usage of the new device itself was more fun. Another interesting finding is that the factor “challenge” generally shows only a marginal significance. If we compare only the subjects of the group of casual gamers, the factor challenge was significantly higher when using the authentic input device. This finding can be explained with the different skills that are required to handle the controllers. The abstract input device (gamepad) demands a considerable amount of eye-hand coordination, whereas the authentic controller (motion control) requires more complex actions with more parts of the body being involved (like swinging the arm while performing a sidestep) – the requirements regarding the players performance are higher in the latter. Related to the tennis game we used in the study, it means that the players using the gamepad – on the most elementary level of understanding – only had to hit the right buttons at the right time in order to outmaneuver the opponent. When using the authentic tennis racquet, the player needed to perform appropriate arm swings to hit the ball at the right time, with the right strength and in the right direction. For inexperienced players, these rather complex actions appear more challenging. To profit from the new control mechanism, game designers have to ensure that the interaction matches the user expectations. The usage of authentic input devices does not automatically increase the entertainment value of a computer game for every player, since they usually have subjectively different expectations regarding the interaction with the game system. A notable difference between the game experience and the real-world experience of the users can reduce or even destroy the sensomotoric immersion. That explains our findings on subjects with great expertise in real-world tennis who did not benefit (in terms of immersion and presence) from authentic input controllers as much as subjects with moderate experience. Later interviews with some of the advanced tennis player participants suggested that this can be explained with the fact that the demands of those players were not met by the gaming system: Sega Superstar Tennis is not a high-fidelity simulation, but a game for the target group of casual gamers with no to little gaming expertise – the group that the majority of the subjects belong to. Advanced tennis players, on the other hand,did expect a more accurate/authentic tennis-simulation which the game we used failed to deliver. There are indeed tennis simulations that offer a high degree of authenticity and realism. The complexity of those simulations overburdens the abilities of beginners and non-players in a way that would totally prevent the experience of immersion or being entertained (at least in the given time frame of 20 minutes). For further research it will nevertheless be necessary to use more realistic games to evaluate the findings of this study. To avoid the problems with the heterogeneous gaming experience, only regular gamers should be chosen as subjects. WHY? IT IS MORE INTERESTING IF NON-GAMERS VERSUS EXPERIENCED-GAMERS ARE COMPARED. In terms of game enjoyment from the use of authentic input controllers, game designers need to clearly define the target group of their game, as it seems difficult to maximize the effect of the authentic controller for both experienced and inexperienced players simultaneously. In the ongoing discussion concerning the degree of relationship between the concepts of immersion and presence, the results of our study substantiate the position that they are closely connected. The correlation between immersion and presence shows considerable overlaps between the two concepts. However, the questionnaire used in the study (PQ) was not specifically designed for the measurement of presence in computer games; therefore our results cannot be generalized without further research. Furthermore, we suggest differentiating the various uses of the term immersion in the field of game studies. Immersion can concurrently be seen as one form of involvement, which is defined as "a psychological state experienced as a consequence of focusing one‘s energy and attention on a coherent set of stimuli or meaningfully related activities and events" (Witmer & Singer 1998: 227). This is very similar to the definition of immersion shown above, but more related to activities in general. Based on the assumptions of the schema theory (cf. e.g. Smith & Queller 2001), Douglas and Hargadon (2000) distinguish between immersion and engagement as modes of cognitive interaction with a medium. The difference between both can be explained by the way the user engages with the medium: If she absorbs the media (more or less) passively without actively reflecting the content (e.g. accepting the stimuli without thinking about or questioning them), she is in a cognitive state of immersion. If the user does actively deal with the content ( e.g. reflecting, analyzing or contemplating it), she is in a cognitive state of engagement (cf. Pietschmann 2009: 73). “The pleasures of immersion stem from our being completely absorbed within the ebb and flow of a familiar narrative schema. The pleasures of engagement tend to come from our ability to recognize a work’s overturning or conjoining conflicting schemes from a perspective outside the text” (Douglas&Hargadon 2000: 155). Using these terms, immersion can be considered a more or less passive and receiving cognitive state, where existing schemes are being processed. This is contrary to other (broader) conceptions of immersion (e.g. Murray 1997, Gander 1999, Björk & Holopainen 2004), which mean basically the same as involvement in terms of Witmer & Singer (1998). The broader concept of focusing one’s energy and attention on specific activities and blocking out distractions or the immediate surroundings should therefore not be called immersion, but rather involvement. This definition includes both modes (using existing schemes and building new/combing existing schemes) of cognitive interaction with the given set of stimuli.10 As a result, immersion and engagement can be understood as two oppositional cognitive states within the broader concept of involvement (see Fig. 5). When playing a good computer game, the user is involved with the game and switches between the underlying states of immersion and engagement – based on the use of cognitive schemes. Fig. 5: Involvement as generic term and immersion/engagement as modes of cognitive interaction with a coherent set of stimuli 10 For example, Neitzel 2008 also prefers involvement instead of immersion in this context.
