Typealike tech uses computers’ existing webcams for gesture control

While it is already possible to control computers via hand gestures, doing so typically involves using peripheral electronic devices or special embedded hardware. The Typealike system, however, brings such functionality to existing computers, no added electronics required.

Currently under development at Canada’s University of Waterloo, Typealike consists of two components: a small downward-angled mirror which is placed over the computer’s webcam, and machine-learning-based software which is running on that computer.

When the user wishes to turn the speaker volume up – just as one example of the system’s capabilities – they simply make a thumbs-up gesture with one hand that
