Jakob Rozman What you need to know about virtual reality in 2023 New technologies are coming in virtual reality headsets, and terms are getting talked about like everybody already knows what they are. Here are most of the terms you're hearing, and what they mean What is hand and body tracking? Hand and body tracking are self-explanatory, though how it is accomplished differs from headset to headset. Early VR headsets relied upon colorful LEDs or multiple cameras in a room to track a user's movement. However, this has advanced to placing sensors directly into the headset. Apple's VR headset is expected to operate independently from other products, so it will likely track the user's movements without an advanced external camera rig. Instead, the headset will be able to see the user via cameras or other sensors, like LiDAR. Controllers are also useful for tracking a user's hands. Rumors aren't clear on whether Apple will develop a VR controller or not. The company may be confident in its headset's ability to track hands without them. What is haptic feedback? Haptic feedback refers to a device's ability to react to software-based interactions with a physical response. Basically, think of the vibrating motors in a controller that tell you when a character has been damaged in a game. A VR headset could take advantage of haptic feedback to alert the user of impending object collision, or software could take advantage for simulating parts of a game. For example, haptic feedback might tell a user something is behind them. Haptics are also useful in VR controllers. The controller might vibrate to indicate their ingame sword has collided with an object, or perhaps, they've highlighted a menu item with a virtual pointer. 1 Jakob Rozman What is LiDAR?. In a VR headset, LiDAR can be used to map a room, so the software knows where objects are. This information can be used to help the user avoid collisions while using the headset.

There have been many new terms appearing on the internet that many of us do not understand. Hand and body tracking is one of those terms. It means that the VR headset uses light to determine the user's position in the room. Haptic feedback is also one of those terms. It refers to the controllers or the VR headset doing different things depending on what happens in a game. VR controllers already vibrate when you hit something in game but there is much to be improved. The most difficult term is LiDAR. LiDAR is a sensor that uses software to help the user not hit something when playing a game.
