The Device: AR Headphone
AR Headphone is wearable technology that is hands-free and adept at communicating with multiple outlets. It embraces features of augmented reality, which includes live casting of the physical environment and direct view of the real-world surroundings . These AR components are accurately produced through sensory input such as sound, GPS data, and video. It is easily operatable with voice commands and requires minimal physical touch to interact with the button, which is located on one side of the headphone. This AR headphone is lightweight and all the components are fully covered by plastic in various colours. It is highly durable in any weather conditions and very comfortable to wear. It can be easily adjusted according to user's head size. It requires either WiFi or mobile connectivity with Bluetooth to deliver its promising features. The exception to this connectivity is MiFi, which is based on data plan.
The mechanism behind the AR Headphone is quite simple. It is totally dependent on the smart chip, radio transceivers and solar batteries. The key to establish communication between AR device and the smart chip is activation of the on/off button and providing voice command and following the voice back prompts. Figure 3 shows the design of AR Headphone.

These outlets includes educational institutions, entertainment centers, religious institutions, retailers, hospitals, private and public transportation providers and other community service providers.
- Enriched Environmental Information: The smart camera in the AR Headphone sense movement, shape, heat, objects and people, sends information to the smart chip which guides wearer to safety by narrowing down obstacles in the immediate surrounding and providing haptic feedback when wearer touch the objects.
How It Works
(Refer back to Figure 1 above)
The wearer touch the button and the AR Headphone is turned “on”.
Then AR Headphone will ask wearer to voice command in order to generate a connectivity via one of the following: wifi, bluetooth or micro USB. The exception is MiFi, in which system will not ask for voice command from the wearer and automatically connects to the data plan.
Once this connectivity is achieved, software application pertaining to this AR device begins to run.
The AR headphone then communicates with the Smart Chip (sensor) via Cloud App Engine (PaaS). The Platform as a Service (PaaS), provides cloud computing components to the software and thus it supplies application over the internet. PaaS makes the development, testing, deployment of application much simpler, faster and more cost-effective.
The AR headphone communicates with the necessary sensor pertaining to user’s voice command input. It then retrieves and update data in both sensor and video databases.
The AR headphone then based on the retrieved data outputs the response wearer needs via voice back command.
Side note: Response relating to wearer’s input command are pre-implemented in the application to be dictated as a voice back command.

Anne is a grade 11 student at Mother Theresa Public School and is medically diagnosed as a person with dyslexia, who has difficulty in learning to read or interpret words but does not affect general intelligence. Today is Monday and she is on a day 2 schedule of her 2nd-semesterclasses, which is as follows: 8:55-10:20 Math, 10:25-11:40 Religion, 11:45-12:45 Lunch, 12:50-2:05 Chemistry, 2:10-3:25 English
Anne enters her classroom, sit quietly at her desk and opens her math book to the page teacher indicate and see all algebra starting back at her. She begins to read it and the teacher begins to write today’s lesson on the blackboard. Anne starts copying the note from the board as fast as she can into her notebook. Teacher continues to talk and erase the problem from the board and begin writing a new equation. The class goes on like this and Anne continues to copy as much as she could and rushes to squeeze it all into the given time. In between, the teacher calls out to the students to solve a difficult question on the board. As usual Jason and few others, the ‘smart’ team, volunteers. Anne tries to follow these students and couldn’t understand them as one spoke too fast and the other too soft. Teacher assign homework, Anne pack her things into her back and hope along through the hallway to her next class. She followed the expectation to the core, to come in, take a seat and quietly listen. This teacher returns all students’ essay on their own religion back to them, as teacher nears Anne’s desk, Anne shifts uncomfortably in her seat and gets anxious thinking the teacher will saying something about her marks in front of her peers, teacher hand out her essay quietly and return to the front of the class. Anne looks down at her marked essay, she got D+ and as she consoles herself that at least she passed, the teacher starts his lecture for the day about beliefs, customs and traditions of Judaism and puts note on the projector screen. Anne again begins copying the notes, squeezing as much information as she can before the teacher changed the next sheet. Anne sat down passively for the duration of the time, half listening and half jotting down notes. She often turned around and looked at the clock, count down the minutes. Finally over, it’s time for lunch.
After lunch, similar activities takes place in her Chemistry and English class, with two exceptions. One, she had to experiment with chemicals for about 30 minutes in her chemistry lab. Anne always loved the time in the chemistry lab as she didn’t have to sit anymore and she is able to experiment with her hands. It always left Anne with energy for her next class. Her English class is always as usual. Sitting down in one place, quietly reading novel, passage, poem or the other and writing about something. Today was full listening, the only difference is listening to her peers' presentation. By 3’o clock, Anne was exhausted and put on a great effort to not slip into oblivion. It’s now 3:25 pm and the day is over at last.
It's now time to put on the AR headphone and activate the smart-chip!
Anne enters her math classroom so happy that her principal and teachers have given her permission to use AR Headphone in her classes. She takes out her AR Headphone and she puts it on and authenticate her identity. She then quietly whispers “please video record”, internally AR Headphone sends the signal to Cloud App Engine and it sends to the Smart Chip, which then sends a message back to Cloud App Engine, who in return sends AR Headphone which voice back “Recording starts now” to Anne who is already began closely watching the math teacher’s explanation of the algebra equation. She is so happy that she didn’t have to write notes quickly anymore. She attentively watch the teacher’s writing on the blackboard and even volunteers and goes up to the blackboard while having command “please pause recording” and having received confirmation “Recording paused” and solves the equation as she fully understood the concept. She then comes back to her seat, put the AR headphone back-on and commands “resume recording” and again hears “recording in progress” message. Anne ends her recording session by commanding “end video recording” and immediately she hears the message “video recording stopped.”
Sitting in her next class, Anne can’t wait to get her essay mark. She knows she did well on the essay with the AR Headphone there is no way. She has used it to get help and write the essay at home. She has opened her religion book and command “Read opened page” and has listened to every single word being read back to her. She then dictated “summarize opened page“ and listen to the summary, which further confirmed her understanding of the article. She then commanded “Search internet and define Buddism”, and received response as “According to Lee Chan, Buddism is ….” following which she command “open MS Word” and received voice back “Word is now open”. Anne then said “on speech recognition” and AR Headphone voiced “Begin dictating” so Anne has simply moved around her room folding and putting her closes away while dictating the full essay. She dictated punctuation marks as well simply by naming them “Huge statues of Buddha can be seen in many cities in China comma, yet very few can be seen in Korea period” and the output on the paper would be “Huge statues of Buddha can be seen in many cities in China, yet very few can be seen in Korea.” She has finished her dictation into the Word by commanding “Print” and the AR Headphone voiced back “Printing In Progress”. Anne couldn’t believe her marks, for the first time she has gotten a A- for her essay.
Throughout the day AR Headphone continued to enhance Anne learning experience. From sitting passively for long period of time, to half listening to the lectures and jotting down notes fast and being so tired that she was not absorbing majority of the information presented Anne had come a long way. She now was more alert, interested and engaged in the class activities. She no longer is disengaged from learning, in fact Anne not only absorbed information, she had great grasp of the content, enjoyed learning and have become an active participant in her learning.
Ranveer is fully blind. He is traveling from Toronto to Sulsback in Germany on emergency. Travelling is a humongous task for him. Ranveer gets help from his family in the airport, which includes ride to the airport, baggage handling and getting boarding pass from the Immigration Officer, until he is ready to go through security gateways. From there onwards, he usually gets an escort, whose job typically was to guide Ranveer through the doors, gates and security personnel all the way to the flight door. To get this escort service, he always have to wait anywhere from 15 minutes to 45 minutes. Then he is all alone in the flights, he rarely asks the attendant for help and only gets up once from his seating to use the washroom facility, until he gets off the flight, then again escort and family services.
This has been Ranveer’s regular travelling experience. No more of this!
Today, Ranveer is travelling with his brand new AR Headphone. As he gets off from the car, he commands “escort needed to unload luggage from car.” AR Headphone, connects with airport escort personnel automatically indicating Ranveer’s location and responds back to Ranveer “Escort on the way. To arrive at your destination in 2 minutes.”
Ranveer continue to dictate “guide to immigration officer servicing my flight” and through the AR Headphone, he hears “Go straight through the doors, turn right and continue walking 2 meters.” As Ranveer does as AR Headphone’s voice over, he has successfully navigated the hall, elevator, and ailse and has now arrived at the designated line for his flight. Ranveer dictate “what is the wait time” and AR Headphone, automatically connects with Immigration officer’s terminal and gets replies back “The estimated wait time is 50 minutes at the current speed officers are processing the boarding system.” AR Headphone system enhances Ranveer’s travel all the way until he clears out from the Immigration system in Germany. Ranveer turn off his AR Headphone when his uncle reach him. With AR Headphone Ranveer’ has navigated the security systems, services and halls of both local and international airport completely independently thanks to Air Headphone. This system uses the network of strategically selected Outlets in conjunction with cloud app to enable fully blind and visually impaired passengers to navigate airport terminal without any escort. The AR Headphone and the cloud app are completely intuitive for blind people. With this device, Ranveer could go from Point A to Point Z without any problem since the audio voice-commanding system is guiding him every step of the way. The AR Headphone with its preloaded detailed map of terminal, uses data from the Airpor partners triangulate Ranveer’s exact location and identifies each and every aspects within 25 meters range of his physical location.The AR Headphone system work in two ways, actively and passively. For instance, when Raveer voice command “direct me first to the currency exchange booth and then to the food court”, the prompt is followed. In any event, Ranveer does not wish to activate this service and is wandering around the airport killing time, AR will state “you are walking pass by corridor E, now you are bypassing the washroom” even without Ranveer commanding. Additionally, should Ranveer want information he will get regular reminder notification of any flight delays, waiting time for departure, weather condition etc .The baggage area is a nightmare for even those that have great vision. Up until now, Ranveer has been no exception. He will for the first time, know which carousel he is standing at and the colour, size and shape of suitcases going around and around.
AR Headphone system isn’t limited to airport and its services. This system enable wearer to navigate any maze buildings and retail centers. It also serves as evident of how technology for the blind people are pushing innovation life AR Headphone to the forefront. Previous tools for these blind people were intended to assist with certain activities while indoor only. Now this AR Headphone more than a simple navigating tool, it in fact is the tool of empowerment and independency of blind.
