Google Cardboard – Adding vision to the blind

As Google Cardboard surpasses the 500,000 mark it reminded me of a possible interesting use for the VI community.

A big issue related to loss of sight is contrast, as vision deteriorates the outside world often lacks enough contrast to adequately identify objects. However, this can in many cases be overcome by observing the same scene through a backlit screen. For example, a couple of years ago my son received a Duplo train for christmas. Due to my sight loss I was unable to see the track. However, my wife used Apple’s AirPlay to mirror what she was viewing onto the TV screen. This increased level of contrast meant I could help build the track. It may seem strange that I cannot see the track when looking directly at it, but can through a screen. But thanks to the increased contrast I can identify outlines.

This is where cardboard could offer some interesting visual cues to the VI. Simply viewing the world through the screen may be enough to add increased contrast, or filters could even be applied to assist in increasing contrast. A step further and similar to augmented reality certain objects could be increased in constrast assisting in mobility or even enjoying a scene otherwise invisible.
