University of Washington computer scientists have developed gesture-recognition technology that brings this a step closer to reality. Researchers have shown it’s possible to leverage Wi-Fi signals around us to detect specific movements without needing sensors on the human body or cameras.
:idea: It is interesting to see a passive radar system being developed for personal gesture recognition.
:ugeek: There have been some interesting DIY experiments in the past using analog TV multipath ghosting for passive radar experiments: http://www.frisnit.com/radar/
😮 Similar passive radar methods have been used by enemy troops to shoot down American stealth aircraft by looking for "holes" in the distributed cellphone network noise signatures. Seeing silence where there should be noise is a "dead" giveaway.
😄 But THIS new wifi-based research that adds to our "arsenal" of personal input methods useful to VR applications is a good thing...
