1D Handwriting: Gesture Input on Smart Glasses Pervasive HCI Lab, Tsinghua University | Summer 2015—Spring 2016

Text entry can be a significant hassle on augmented reality (AR) devices, as there were no practical methods for input. In this project, I worked on 1D Handwriting, which enabled text entry with one-dimensional gestures on Google Glass. The users’ text entry rate reached 19.6 WPM after training. This method can also be useful for other one-dimensional constrained interfaces, e.g. the side of a smartphone and smart wristbands.
