Microsoft Developing SoundWave Depth and Motion Detection Using Doppler Effect

Although this isn't exactly Kinect related, it does fall into the niche technology that this site aims to deliver in terms of reporting on NUI advancements. Microsoft; the guys behind delivery Kinect tech to the masses, are experimenting with a new type of technology that utilizes the Doppler effect with inaudible sound waves. Think sonar for your laptop.

The tech; tentatively called SoundWave, is able to detect motion based on the Doppler effect that detects movements and gestures based on their proximity to the computer.

In the case of SoundWave, your computer’s built-in speaker is used to emit ultrasonic (18-22KHz) sound waves, which change frequency depending on where your hand (or body) is in relation to the computer. This change in frequency is measured by your computer’s built-in microphone, and then some fairly complex software works out your motion/gesture.

One very promising aspect of this tech is that it is able to be deployed using current hardware configurations in your computer. Speakers are all you really need which means it may not be far off before Kinect like depth sensing tech can be implemented in our cellphones as well!

Check out the video to see it in action. Exciting stuff!
