The real-time 3D depth mapping enabled by the Google Tango project lets us
create a live sonic depth map for blind people. This serves to support obstacle detection
and avoidance beyond the reach of the white cane, and even enables blind detection
of the shape of nearby objects, thus aiding with nearby object identification.
Under this proposal, the existing Android app The vOICe for Android
(available for free on
 In the longer run, blind people will benefit from fully wearable depth mapping through the use of future mass market augmented reality glasses that incorporate Google Tango technology (The vOICe for Android already ran on Google Glass).

Precursor work on creating depth maps from stereo vision using a Windows PC
was done as described on the Stereoscopic Vision for the Blind
page, but The vOICe for Android is much more suitable for
mobile use, so development focus had shifted towards that and awaited availability
of 3D camera technology for intuitive feedback on nearby obstacles for the blind.
Google Tango will now enable this on mass-market mobile devices.
