During the Google I/O Ice Cream Sandwich Preview, “Head Tracking” was brought up as a feature available to developers. It is what it sounds like, your devices camera will know where your head is and display differently based on where you are in relation to the screen. This “Head Tracking” will allow things like video chat finding your face and staying focused on it, changing perspective on a 3D scene based on angle, etc.
It seems to be a technology that could put Android out in front although there will also need to be developers willing to work with it. We have seen this type of technology before although never in a practical use like a smartphone.
The below video is only posted as an example and was originally created for the Wii game console but features how it works:
The Wii Head Tracking Video was removed by its creator therefor no longer available
At I/O Google demoed a version of this with face distortion and sound sensitive video chat zoom. This will be available to all developers within Ice Cream Sandwich in the form of API’s. We can’t wait to see how developers use this new feature.
UPDATE: With the head tracking api being a new technology for mobile devices we had assumed it would take off from the release although this does not seem to be the case. Most of the head tracking apps and concepts that we find are nothing more than demo’s as to how it could be used. We have yet to see one useable app be developed using the head tracking api for users. If anything changes and something great or even remotely useful at this point is released we will let you know.
