A while back we talked about how we were able to help people type up to 30 wpm on their smart watch. Now we've updated the research to apply to an even smaller typing surface on the side of a pair of smart glasses.
The challenge in adapting this from a smart watch is twofold:
Adapting the SwipeBoard technology to the smart glasses with a heads up display gets around the first problem. The second problem is addressed by dividing the long strip into three, using a piece of tape for tactile feedback on the zones and eliminating the diagonal gestures with vertical gestures in each zone.
This is the first known work in this area and there are lots of possibilities for future study. Have a look at the video below for more details.
