Motion sensing using the doppler effect in browser
- ncr100 6y agoThis could be used for reach detection. Like as if you are reaching towards your mobile device. Pitch would increase. Or it could be used for detection that you are showing the device to another person, the pitch would fall. And then it would rise. And if you had gyroscope data, then you would see a radical movement in the middle.
- withinboredom 6y agoIt's pretty cool (and kinda freaky) that it detects my chest rising and falling while breathing. Only works with my shirt off though.
- jcims 6y agoI can’t run this one but most likely it can also find your pulse.
- wanderingstan 6y agoThis is several years old. When it came out, I immediately created a version of Flappy Bird played by actually flapping your hands. It kinda blows people’s minds when you show it to them! HandyBird: https://wanderingstan.github.io/handybird/ https://wanderingstan.github.io/handybird/
- walterbell 6y agoSimilar techniques can be used to "see" through walls, floors & ceilings with low-cost WiFi.
- kumarvvr 6y agoI wonder if this could be an alternative to PIR motion sensing.
