Android bluetooth touchpad emulation

I was thinking about the possibility to use my Android device as a touchpad with usual computers (without the need of special software on the computer's side).

Do y开发者_开发问答ou think it's possible to identify the android phone as a bluetooth mouse against a computer? Do I need to root my phone or does the Android SDK/bluetooth stack allows me something like that?

I'm knew to this topic. Does anybody can provide me some useful links / information ?

This is exactly what I have done. It is my bachelor thesis. You need a rooted phone and Linux on the computer side. You do not have to install anything on your computer. It uses the HID class drivers.

You will need is Bluetooth HID profile support on the android phone, and also for the phone to act as a HID device i.e support the Bluetooth HID device role.

HID is officially supported in honeycomb. See this - Android Bluetooth Features I think the current support is only for HID host role , i.e. for keyboards / mice etc to connect with and input to the phone.

Also currently there are no APIs exposed for applications to access.

Yes it can be done, it is often referred to as HID over GATT. There is at least one app on the Play Store that does that. No root needed, no software on the PC side to install. I could find two GitHub repositories implementing such solutions:

• BLE-HID-Peripheral-for-Android
• BLE_HID_Example

Though neither of them have been maintained in years so it is fair to assume they won't compile and work out of the box.
