CSE is pleased to be home to new research work from Professor Wen Hu, who is the recipient, alongside Associate Professor Chun Tung Chou, of a significant, $405,000 ARC Discovery Projects 2022 grant. 

The project is investigating the capacities of mmWave radar devices–a special class of radar technology that uses short wavelength electromagnetic waves to sense and measure motion at the millimeter distance. The team hopes to lay the experimental foundations for showing how emerging commercial mmWave radar technologies and their ubiquitous hand-gesture sensing and recognition characteristics could be used in our homes and workplaces, and potentially, how they could sense human gestures for multiple smart environment applications at scale: including uses as varied as a new way for people to interact with computer systems; or an industrial facility wanting to automatically shut off machinery when a person gets too close. 

The key to this breakthrough lies in harnessing mmWave radio to enable sensing beyond wireless communications–a recent technology breakthrough commercialized by Texas Instruments. Human gestures can be sensed by the radio signal patterns in a receiver, as different movements cause distinct signature fluctuations when they obstruct the paths between a sender and the receiver. Ultimately, the project aims to deliver a prototype of a fully functional and optimised hand gesture sensor network system, demonstrating mmWave-based sensing for smart environments in real-life scenarios. This research fulfills a critical role in the research to industry pipeline for new kinds of mmWave devices.
