Section 1: Introduction
The world nowadays is all about getting to your destination in the fastest mean. But
things can get tough especially when you are among the directionally impaired who don’t take to
the road without the aid of GPS device. But imagine if this system becomes a part of you, not in
your pocket, but right next to your eyes. Why need to bring GPS when you can actually wear it?
Not only you will get direction easily, but you will also have the advantage of keeping your
hands off it by controlling the system through your voice. For that, a Personal Navigation
System glasses should soon arrive to help you easily find your way while on foot.
The purpose of the improvised glasses is to overcome one of the most obvious problems
people might have with most current navigation systems. Some people have had serious
accidents due to disengaging their own common sense in order to follow the path down which
their GPS guides them. People ignoring train signals, and even driving on the tracks, has
actually happened. Looking at the screen while traveling can be dangerous. Especially with cool
touch screen GPS that has all the interesting menu options, drivers are easily distracted. It is
even more dangerous for beginner drivers. They have the tendency to look at the screen
frequently. Programming the GPS while moving is extremely dangerous as users have to look at
the screen and enter the information. They have to take their eyes off the road. It is as
dangerous as texting while driving or moving.
With this system, all they need to do is be aware of the LED light while they walk or drive
so any accident can be avoided. Besides, they also do not have to bother to key in the address
of their destination because all because they have to do to is to say it and the system will do the
work. This product is not only convenient for normal people but also for those who are vision
impaired. It can benefit them in terms of going anywhere they want without being accompanied.
And if we are talking about the design, just name any. Glasses can always be improved in that
sense so customers will always be able to choose.
This product can reach everybody all over the world because glasses are not a new
invention. Thus people would not be that awkward the first time they hear about it. After all,
there is a lot of people wear glasses as accessories even when they do not have any eye
problems. This opens the chances of getting customers even more. Plus, even a vision impaired
person can buy this product. Therefore the range of the group target customers once again
2
expands. Besides today GPS has become a must have device if ones want to travel or drive. It
is because people want to go green, paperless and save the trees. Then most drivers today do
not want to through the “hard work” of memorizing the road they need to use.
The major component of this device is the voice activated GPS. The user is able to enter
the desired destination without having to key in the information. It is an important feature as
typing can be a hassle especially when driving or walking. With this feature, drivers or users will
not have to take their eyes off the road anymore to enter the information. However there is a
minor problem with voice activated device. The problem is the background noise in the
environment. The noise will cause distortion to the users voice signal. Fortunately, this problem
can be overcome with the use of noise cancellation system. It can reduce the noise and enable
the information to be sent clearly from microphone to the GPS.
Next, the LEDs indicator is another important feature of this device. There will be a LED
attached at each side of the glasses frame. One of the LED will be in green color and the other
one is in red color. The green LED indicates that the user is walking or moving in the right route
or path. The red LED indicates that the user is taking the wrong turn or street. The LED will
increase the user alertness besides the voice instruction.
After that, this device will be powered up by two lithium coin batteries. This type of
battery is chosen as it is cheap and has small size. It will fit on the frame of the glasses. The
figure of the device is similar to the figure below.
Figure 1
3
The components such as speaker, built-in microphone, GPS chip and batteries will be put in the
plastic casing. The casing is in solid color to hide all the electrical components of the device.
The user will be able to access the casing easily as the batteries need to be replaced. The
on/off switch and the reset button will be located at the right frame. It is because majority of the
population is right handed. Thus it will be easier for the users to access the buttons.
Generally, “Personal Navigation Glasses” enables user to move around stylishly and
confidently. It is because the user gets to wear trendy looking glasses. They also get the guide
from GPS without having to bring a thick and large rectangular device and most importantly
without risking their life.

Figure 2.1.1 Functionality block diagram
The Figure 2.1 above shows the functional flows of the Personal Navigation System
Glasses. Firstly, the user needs to insert two CR2032 lithium coin batteries to supply total 6
volts energy to the glasses. Then, to turn on the device the user can simply hit the on/off button.
6
After that, the user has to give input to the microphone through the speech recognition process
to initially set the destination.
The speech recognition fundamentally functions as a pipeline that converts PCM (Pulse
Code Modulation) digital audio from a sound card into recognized speech. The elements of the
pipeline include transformation of the PCM digital audio into a better acoustic representation,
identification of phonemes spoken, reducing the computation and increasing accuracy.
Significant tolerance against variations in the acoustic signal related to this would be voice level
variability, the ability to cope with microphones with different frequency response and with
changing environmental conditions. Since the device works based on the voice commands, the
whole process will go through quite a number of interactions between the user and the verbally
responding interfaces.
Given that the instructions are simultaneously being recognized, the input would be
configured by the GPS to work on the positioning calculation. The GPS calculation in the
receiver uses four equations in the four unknowns x, y, z, tc, where x, y, z are the receiver’s
coordinates, and tc is the time correction for the GPS receiver’s clock. Depending on the
accuracy of the clock in the GPS receiver, the determined position will be more or less wrong.
For the practice of GPS based navigation this would mean that no determined position can ever
be of any use, as the runtimes of the signals are so short, that any clock error has an
overwhelming influence on the result. By constantly recalculating its position, the GPS receiver
can additionally determine the speed and direction of a movement (referred to as "ground
speed" and "ground track").
Corresponding to the GPS directional procedure are the red and green LEDs which are
going to flash on showing whether or not the user is heading to the correct route. It somehow
keeps up a correspondence just to certain range of movement since the user might not want
undesired recalculation every time he moves his head.
Besides, the speaker will keep
providing the users with voice guide direction in order to steer the user to the desired destination.
The four basic functions that need to be accomplish by the device is simplify in the Figure 2.1.2

Figure 2.1.2 Functional Hierarchy
The figure above summarizes the major components needed for this project to work, together
with their respective functions. Basically, the project is built on five major components that need
to accomplish four different functions.

Section 2.2: Technical Description of the Design and its Components
Overall Hardware Functionality of the Design
The design is a GPS built-in glasses. Thus, the group has to consider the user’s comfort
while designing this project. The final product should offer the advantage of having the personal
GPS device while keeping the original function of glasses.
Figure: hardware block diagram

The main component for the project is the power source. The group is planning to use
two Lithium Batteries to support the system. The chosen battery is the Energizer CR1216
Lithium Coin. The dimension and its specification can be seen as below:
Figure: the battery dimension
Figure: the battery specification
10
Then, to start the system, the user must press a mini push button located at the right
side of the glasses frame. The group decides to use the mini push button switches which are
found in sparkfun.com. These switches are high quality of Omron type B3F momentary on
switches. It is an ideal visible reset switch. It mounts directly into standard bread boards. The
allowable current flow is up to 50mA. Other than to be used as on/off button, the group adds
another button to be used as reset button. Both of them will be built into the right side of the
glasses frame. The dimension of the switch can be seen as below:
Figure: actual picture of switch and its dimension
Next, a speaker is needed to convert the electrical audio signal into sound. The group
decides to use two speakers. Each one of them will be implanted both sides of the glasses
frame. The chosen speaker is a product from Shenzhen Honson Electronics Technology Co.,
Ltd. The speaker dimension is 30mm x 10mm which is suitable to be built into the glasses
frame. The link of the speaker < http://szhonson.en.alibaba.com/productshowimg/43176075311

the pictures below are the actual
speaker and its specifications:
Figure: the 30mm x 10mm speaker
Table: the specifications
Next, microphone is the questionable component for this project. There are two design
alternatives for this design:
1) Using only a microphone and
2) Using two microphones.
The alternative 1 is preferred for this design as alternative 2 will lead to larger battery power
consumption. The important key while making the decision is the capability of two lithium ion
batteries that the group has chosen.
12
The important component is this design is the GPS itself. The group decides to choose
TomTom GPS as the main programming of the system. Although this brand is not famously
known as Garmin, it has almost all the specifications up-to-date and it also better in term of final
price of the product. A GPS receiver will be installed into the frame and this component will
receive information from GPS satellites. The receiver will calculate its distance from the
satellites and use triangulation to figure out its own location. The directions to the desired
destination are guided by voice command of the system.
Lastly, two LEDs (one green and one red) will be used as a sign to remind the
user that the road taken is in wrong direction. The red LED will light up when the user makes a
wrong turn and the green LED will light up when the user corrects the direction. Below is as
example of LEDs that will be used:
Figure: LEDs
Overall Software Functionality of the Design
The interactive voice response programming allows user to communicate with a device.
In this design, the system will request the user to input the address. Then, it will repeat the
information to the user a few seconds after that. By doing this the user will be able to confirm
the destination information is correct or not. Below is an example of speech recognition
architecture:
13

Network (HMM/ANN) architecture (source:
http://cslu.cse.ogi.edu/tutordemos/nnet_training/tutorial.html)
Voice Recognition Program plus VRE
Since this design works based on voice command, the system has to be familiarized
with the user’s voice and its style. Before the product can be used, the user must train the
system to recognize the unique voice of its owner. Hence a Voice Recognition Program is
needed for the design. Most voice recognition systems are in discrete word system. The user
will have to pause between words but this is only acceptable for situations that require user to
response only a word. Another type of the program is a connected word voice recognition
system where the user can naturally speak but the words must be spoken clearly. To train the
voice system, the user has to speak some words or sentences clearly while wearing the GPS
glasses. The program then will compute the voice samples into data and store it as a template
in a program data structure. To improve the accuracy of the voice recognition system, a voice
recognition enhancer (VRE) software algorithm can be used on the DSP. This software works
by analyzing the sampled input data and the program will decide which one is speech and which
one is noise. Speech will be left and the noise will be reduced in amplitude. Noise can be
differentiated from the speech due to one main principle of noises. Unlike speech that varies
14
rapidly in amplitude and pitch, noise varies slowly. Sometimes, noise can also be considered as
stationery.
Noise cancellation technology
One of the disadvantages of the design is the environmental noise like traffic noise,
people talking, alarms and other sounds can reduce the accuracy of the speech recognition
program to detect the information. Hence, noise reduction software is installed into the device
microchip. This software can reduce the error by removing the unwanted background noises.
Why bother with this software? It is because by reducing the potential error can save the user
from repeating the location or address and time will not be wasted. The group is planning to use
Noise Reduction Gen 2 software (a product from Adaptive Digital Technologies, Inc). This
software is a good choice for this project as it can tolerate high background noise environments.

Section 2.3: Mathematical or Other Principles Embedded in the Project
Fundamentally, there are two main functionalities been represented in this particular design;
speech recognition and the global positioning system, GPS. To practically customize such
elements, certain principles have been analyzed and inserted in the whole process of
understanding and implementing those functionalities in the project.
2.3.1 Speech Recognition
Speech recognition fundamentally functions as a pipeline that converts PCM (Pulse Code
Modulation) digital audio from a sound card into recognized speech. The elements of the
pipeline are:
1. Transform the PCM digital audio into a better acoustic representation

The first element of the pipeline converts digital audio coming from the sound
card into a format that’s more representative of what a person hears. The digital
audio is a stream of amplitudes, sampled at about 16,000 times per second.

To make pattern recognition easier, the PCM digital audio is transformed into the
"frequency domain." Transformations are done using a windowed fast-Fourier
transform. The output is similar to what a spectrograph produces.

The fast Fourier transform analyzes every 1/100th of a second and converts the
audio data into the frequency domain. Each 1/100th of a second result is a graph
of the amplitudes of frequency components, describing the sound heard for that
1/100th of a second. The speech recognizer has a database of several thousand
such graphs (called a codebook) that identify different types of sounds the
human voice can make. The sound is "identified" by matching it to its closest
entry in the codebook, producing a number that describes the sound. This
number is called the "feature number."
2. Apply a "grammar" so the speech recognizer knows what phonemes to expect.

One of the techniques to reduce the computation and increase accuracy is called
a "Context Free Grammar" (CFG). CFG’s work by limiting the vocabulary and
syntax structure of speech recognition to only those words and sentences those
are applicable to the application’s current state. The important feature about the
CFG is that it limits what the recognizer expects to hear to a small vocabulary
and tight syntax.
16

CFG’s slightly change the hypothesis portion of speech recognition. Rather than
hypothesizing the transition to all phonemes, the recognizer merely hypothesizes
the transition to the next acceptable phonemes. When the user has finished
speaking, the recognizer returns the hypothesis with the highest score, and the
words that the user spoke are returned to the application.

Speech recognition using a CFG requires a 486/33 to run real-time.
3. Figure out which phonemes are spoken.

The background noise and variability problems are solved by allowing a feature
number to be used by more than just one phoneme, and using statistical models
to figure out which phoneme is spoken. This can be done because a phoneme
lasts for a relatively long time, 50 to 100 feature numbers, and it’s likely that one
or more sounds are predominant during that time. Hence, it’s possible to predict
what phoneme was spoken.

For the speech recognition to learn how a phoneme sounds, a training tool is
passed hundreds of recordings of the phoneme. It analyzes each 1/100 th of a
second of these hundreds of recordings and produces a feature number. From
these it learns statistics about how likely it is for a particular feature number to
appear in a specific phoneme.

The speech recognizer needs to know when one phoneme ends and the next
begins. Speech recognition engines use a mathematical technique called
"Hidden Markov Models" (HMMs) that figure this out.
4. Adapt to the user’s voice

Speech recognition system "adapt" to the user’s voice, vocabulary, and speaking
style to improve accuracy. A system that has had time enough to adapt to an
individual can have one fourth the error rate of a speaker independent system.

The recognizer can adapt to the speaker’s voice and variations of phoneme
pronunciations in a number of ways. First, it can gradually adapt the codebook
vectors used to calculate the acoustic feature number. Second, it can adapt the
probability that a feature number will appear in a phoneme. Both of these are
done by weighted averaging.
17
2.3.2 GPS (Global Positioning System)
For the determination of its position on earth, the GPS receiver compares the time when the
signal was sent by the satellite with the time the signal was received. From this time difference
the distance between receiver and satellite can be calculated.
The calculation of a position from 3 satellite signals is called 2D-position fix (two-dimensional
position determination). It is only two dimensional because the receiver has to assume that it is
located on the earth surface (on a plane two-dimensional surface). By means of four or more
satellites, an absolute position in a three dimensional space can be determined. A 3D-position
fix also gives the height above the earth surface as a result.
The GPS calculation in the receiver uses four equations in the four unknowns x, y, z, tc, where x,
y, z are the receiver’s coordinates, and tc is the time correction for the GPS receiver’s clock. The
four equations are:
18
where

c = speed of light (3 ´ 108 m/s)

tt,1, tt,2, tt,3, tt,4 = times that GPS satellites 1, 2, 3, and 4, respectively, transmitted their
signals (these times are provided to the receiver as part of the information that is
transmitted).

tr,1, tr,2, tr,3, tr,4 = times that the signals from GPS satellites 1, 2, 3, and 4, respectively, are
received (according to the inaccurate GPS receiver’s clock)

x1, y1, z1 = coordinates of GPS satellite 1 (these coordinates are provided to the receiver
as part of the information that is transmitted); similar meaning for x2, y2, z2, etc.
The receiver solves these equations simultaneously to determine x, y, z, and tc.
The calculation is restricted to locations on the earth surface. However the earth is not a perfect
sphere. The surface of the earth in this case means the earth geoids, corresponding to sea level.
If the receiver is located on a mountain, the determined position again is afflicted with an
inaccuracy, as the runtime of the satellite signals is wrong.
By constantly recalculating its position, the GPS receiver can additionally determine the speed
and direction of a movement (referred to as "ground speed" and "ground track").
Another possibility of determining the speed is by using the Doppler's effect which occurs due to
the movement of the receiver while receiving the signals.
19
Section 2.4: Performance Expectations/Objectives
There are five main objectives that the Personal Navigation Glasses must fulfill for it to
be considered as a successful device. First, it is an absolute must for the GPS to give accurate
directions and guide. It is because accidents did happen due to inaccurate directions. As some
drivers totally rely on the GPS and abandon their sense of direction, there are cases where the
GPS led the drivers into lake or driving on train tracks.
Second, the Personal Navigation Glasses must be able to power up the correct LED
indicator. If the wrong color of LED is flashed the user will get confused and distracted. The
confusion might lead to time delay as the users need to figure out whether they are on the right
track or not. To make it worse, distraction might lead to accidents. To prevent accidents is the
main objective of this device. If it fails to do so, it cannot be considered as successful.
Third, the Personal Navigation Glasses must be user friendly. A device is considered to
be user friendly when it is easy to use by everybody and safe to use. This device must have the
simplicity where the users just need to push on/off button to get started and then input the
desired destination. There is also a reset button if the users would like to change the destination.
Then the device must be safe to be use. There are lots of concerns about microwave radiation
as people are worried about their brain being fried. As there are lacks of formal studies to prove
microwave radiation to be unsafe, the radiation is claimed to be safe. It has also been approved
by the FDA to be used by consumers.
Fourth, the Personal Navigation Glasses must be cost effective. Despite of its quality
and state of the art technologies, the price must be within reasonable range. The components
for this device must be acquired without spending excessive amount of money.
Fifth, the noise filter must be able to filter the background noise. It is to ensure that the
voice data (instruction) that the user input contain minimum or no background noise. It is very
important for the GPS to receive an accurate data to minimize the error.
20
Section 3: Critical Evaluation of Project
Section 3.1: The "Good"
By building this personal navigation glasses, people now can communicate with
computer or programmed device that has GPS technology. A microphone and a speaker will be
installed to the glasses’ frame. These components will be small enough to be built in the frame.
Based on last marketing statistics, we can say that this personal navigation glasses will have a
high demand from the customers. It is because of the interesting functions that it has and it is
just an improvisation from the basic GPS navigation device.
Furthermore, this Personal Navigation System glasses are design for people who have
short sighted eyes and normal eyes. This product can also be used by blind people as it is
activated by voice. So they do not have to type in the address of the desired location .The main
materials used in the glasses are CR-39 plastic lenses and nylon frame. Both types of materials
are chosen because of their strong and lightweight properties.
Section 3.2: The "Scary"
It is quite costly in order to build this Personal Navigation System glasses as all the
components used are built-in components. For the GPS device price, we can see that the basic
price for the device is about S150 but it is do not have some of the important features that we
need like higher-quality speaker, travel conveniences, navigation without signal, and also voice
address input. For a better GPS navigation device, we have to spend about $300, which is quite
high.
Furthermore, the battery and electrical components in the frame might add weight to the
glasses. The users might feel uncomfortable wearing it. Besides, it is more risky to wear this
personal navigation glasses. It is because the durability of the glasses is the same as the
normal glasses and it can break if the same force is applied. But, it will cause huge loss as this
personal navigation glasses cost a lot more than the normal glasses.
21
Section 3.3: The "Fun"
The most motivating aspect of this project is the feeling of satisfaction and
accomplishment for logically creating this device from start to finish with nothing but our own
perception and ideas. This Personal Navigation System glasses is not something that takes a
lot of time to complete, but once we succeed to build this device, it will create a new technology
device that go along with the development of GPS. This is a device that we would use for
ourselves, and many other people would use in their cars for ease of communication. Basically,
we know that this Personal Navigation glasses will have a high demand from the market once it
is created, so with this perception, it helps to motivate the team and drive us to complete this
device.
Section 3.4: Funding of Project
The main method of funding our prototype will be rooted in finding sample of glasses
from manufacturers that we need to make a test for try and error. A majority of our design
needs one chip that has GPS program installed in it, so we need to use the glasses with a highquality frame in order to ensure that it will not be easily break. Additionally, we could most likely
find funding from any corporation or large company that frequently use GPS or the companies
that involve in selling the GPS devices. The best route to take would be to go through a
company already involved with Stevens and present our idea to them. If they find it useful,
chances are that they would see no problem providing some aid due to the fact that our project
cost will be insignificant compared to anything they are currently developing.
Regardless,
finding funding for this design will not be a problem given the wide appeal and low cost factors.
22
Section 4: Summary
Consisting of a GPS receiver, a built-in microphone and speaker and of course the main
material; a pair of glasses, this GPS-infused pair of glasses has integrated LEDs in the frame
that wearers can see in their periphery. There won’t be any maps or virtual reality with these
glasses. It just points to the direction the user needs to follow by lighting up the LEDs. The team
should have raw materials like wooden stick, thin glass, LED, wires and several other minor
tools for a prototype because it opens rooms for ideas and improvements once we see it in 3dimensional shape. For that the project will have additional cost but it would not be significant.
In terms of marketability, since the product may be considered as a new innovation, it would
have two obvious possibilities.
Firstly, it might have an impact that people would be curios with this new invention and
end up buying it which is good because there is no competition from other parties, yet. Secondly,
people become not interested with the item as they found it ridiculously expensive or maybe
they are comfortable using current GPS device as it is.
Overall, this product can reach everybody all over the world because a glasses is not a
new thing thus people won’t be that awkward the first time they hear about it. After all, there is a
lot of people wear glasses even they do not have any eye problems so this opens the chances
of getting customers even more. Plus, even a blind person can buy this therefore the range of
our target customers once again expands. In fact, with a little more development and a sleeker
design (maybe in sunglasses?) this product would no doubt have its place within any geek's
gadget collection.
