Design Google Glass for the blind people.

I would choose 3 problems:
- Identifying people by themselves / they have to touch and smell
- Searching or typing by themselves (Googling )
- Navigating roads themselves or within their houses

Solution:

It looks like google glass w/o the glass and switch on and off button and a volume button
The glass would work on speech rather than being connected to a phone. It will be connected to wifi / (not cellular data). It figures out wifi on its own and tells the user who is wearing it to choose a wifi
When there is a person around, the glass identifies unique features about the user and tells blind person wearing the glass. If the person is frequently seen in the blind person’s life then the user is asked to identity the person so that glass can tell the user when the person is around again
Searching / Googling will be a mode / a button the glass frame to switch on google and take the input.
Glass will identify obstacles while the user is walking. The glass is supposed to identify if the user is sitting or moving. We can also give the control to the user to switch on if the user needs to identify the roads.

Priority(based on the ROI):

Speech enablement on google glass with the basic buttons
Person identification
Navigation identification
Rest we can build in subsequent versions. We should not pick up the search feature because I think users should already be acquainted with the google speech search on phone

Success metric:

Sales
DAU using person identification feature and retention on the identification feature
Bugs reported

Next steps:

Understand the current feature usage and see if we missed any basic requirement in a blind person’ life
