Easy and fluent touch navigation is a major factor developers consider when launching a native mobile or tablet app. However, a new tablet aimed at allowing users to navigate apps and screens using simply their eyes has the potential to transform all that. Talk about a major in-the-wild change to the way we use devices.

The tablet contains two sensors along the bottom edge of the tablet to track your eyes. The folks at Engadget were able to test the new device:

“Two sensors along the bottom edge of the tablet track both of your eyes and after a slightly laborious configuration setup, we were able to tour around the prototype slabs features without laying a finger on it. The navigational dot was a little erratic, but we’ll put that down to prototype nerves. The tablet was otherwise able to follow our eye-line and fulfill what we wanted it to do.

Returning to the home screen by targeting the kill box in the top right corner proved to be the most difficult thing — we soon resorted to tapping at the screen for that.”

The only way to possibly test this new device is to test in-the-wild. It is not plausible to fully test a drastic change like this only in the lab. As we saw from Engadget’s real world test, there are still a few kinks that the makers DoCoMo need to iron out. Another thing to think about is that if this DoCoMo prototype catches on, developers will need to rethink usability testing for their applications.
