How would you design a computer to mimic the input of brain signals from the five senses of a human being (taste, touch, smell, hear and see)?

Clarification:

- Can you clarify what is the goal of this computer? Am I right to assume the goal of this computer is to help people feel those senses if they couldn't feel them by themselves? Is it OK to assume that the output of the computer are signals that can be perceived by a human brain? And the physical form of this computer is not limited to a desktop or laptop?

Who do we design for:

- There are a few persona that I could think of that this product could be useful:

- People with disability that have lost one of those senses

- People who want to connect with each other remotely such as couples who are having long distance relationshp and are using video chat but want more

- Gamers who play virtual reality games that want to feel more real while playing the game

I'd like to focus on people with disability, because these senses impact people's quality of life gravely. Such technology when applied in healthcare could bring happiness back to people. Also, patients are probabily a much bigger market for the product with willingness to buy than virtual reality game players, or people who woud like to use this product when they remotely connect with friends and family.

There are many different kinds of disabilities. Blind people cannot see, deaf people cannot hear, amputees cannot feel with hands or feet. I'd like to further narrow it down to address their needs. I suggest we pick blind people, as much of sense of life is perceived by sights. Lost of eye sight has huge impact on people's mobility and independence.

User needs:

- Blind people can use a computer that simulates eye sights so that they can see

- They need to be able to turn on/off the device when they want to see and when they do not want to see. E.g during night when they want to sleep

- They need to be able to move around with the device

- They need to be able to locate the device if they put it down and are unable to see where it is

- They need to be able to see in colour, adjust light, far or near

Prioritization:

- Able to turn on/off - brain needs rest

- Able to move around with the product - make no sense to be locked down and attached to one place

- Able to adjust the range of sighting, colour etc

Solutions

- on/off: use a physical switch, use voice commend

- move around:

-- a lightweight, wearable device that can connects to their brain from skin contact: glasses, helmet, watch, Pin or brooch , mask

-- batter operated, rechargable, can plug into electricity for charging or power directly

- adjust shade, sighting range, colour

-- manual adjust using physical buttons, button must be easy to differentiate through touch

-- voice commend

-- AI  auto predict adjustment + voice confirmation

Pick a solution:

- Pick glass over watch: wearable, fashion statement, non-intrusive, at the right height, can function as shades, connect to brain through skin contact behind ear for subtlety. Watch is not at the right level, need to lift/move arm around to "see". Signal needs to travel far, may drain more power

- voice commend with physical buttons as backup for situations when voice is not appropriate, e.g in Library

- can have a base charging station + long running battery. Maybe solar powered for outdoor charging during the day

- sighting range can be adjusted via head or facial/eye muscle gesture. squintting eyes for far sights, moving closer to object for near sights

- device can use camera and computer vision for capturing sights and facial expression. Sensor for brightness and temperature etc

Evaluation:

- Sounds familiar? Google glass next gen! Many technologies exist, e.g camera,computer vision, AI prediction, solar power, voice command. Privacy can be improved. No recording. Clearly label as medical device

- Why glasses instead of artificial eyeballs? - Eyeballs require operations. Some patients may have some eye sights and would like to keep their own eyes and only need device for enhanced sighting.

Metrics:

- # of units sold since launch per month, per quarter, per year

- % sales growth

- customer feedback, # of support calls per week, per month, # of returns.

Clarifying Q's
-Why we are doing this? [Assuming for creating immersive experience Ex- Gaming and research]
- By computer, do you mean a separate device or as an attachment to some current gadget?
I will consider this across all the categories I can think of. 

Using the photo way for the first time because I prefer thinking while writing :) Feedback is really appreciated
