The new Samsung Galaxy S4 have and interesting new type of gestures called "Air Gesture" that use an infrared sensor to process users hand movement in front of the screen, adding a "pre-touch"/"proximity" event, in which the fingers are detected before the touch.

I'd like to use this "Floating Touch" event in one of my apps. I searched both on Google and in the Samsung Developers Center, but I couldn't find any API or information about that.

Are the API available or is too early? Does someone have any link/info?

There is a good youtube video from a Google I/O session called "the sensitive side of Android" that explains how you could do something similar. Basically you use the light sensors and then you register a drop. This is quite simple but you gotta remember that changing light sources while running the app can affect the results of this feature.

That said I think they use hand detection on the front camera in order to pull off all those gestures and that would be quite complex. Also I haven't seen any api that makes it simple to do hand detection.

  • Nope, they do not use the camera at all for hand gesture detection in S4. Tested simply by blocking the camera. – Aras Jan 04 '14 at 08:43
  • Thanks @Warpzit, do you know where can I get the source code in the I/O demo? I'm really having trouble sampling those data from the sensor:( – Nevin Chen Feb 18 '14 at 12:30
  • In the samples folders there is a project called Accelerometer Play, API Demos (OS - Sensors). They'd be a good place to start. – Warpzit Feb 18 '14 at 13:18

    @mah actually user2594675's answer is the correct one for this question. – zrgiu Dec 02 '13 at 10:55

    @zrgiu Actually, link-only answers are not permitted at stack overflow, so it doesn't matter what the link contains. What is permitted is copying enough of the content from that link into the answer so that the answer can stand alone and be useful even after the link breaks (but including the link for reference, attribution, and additional details is very welcomed). – mah Dec 03 '13 at 00:05

If you are looking to Samsung Mobile SDK, you'll find that S4 doesn't support Gesture SDK although it had "floating gesture" function. If you google "Samsung Mobile Gesture SDK with S4", you'll find some info....

Only Galaxy J and Note 3 support Gesture SDK as far as I know.
