androidtrackpad's Introduction

Android Trackpad

Connect your Android phone to Windows or Linux system as a trackpad

How to use

Install PC side based on your system, install apk on your Android phone
For bluetooth mode, please pair phone with your PC in advance
For Wifi mode, please start a hotspot on PC and connect your phone with it (Or if your router support port forwarding, this program may also work for PC and Android in same network. The port is 10086)

Note

There are some issues with exiting the program (See Windows README.md for detail)
All are solvable by disconnecting from Android side first

Demo

This is a live demo on Linux laptop with Bluetooth connection

Features

Connect via Wifi, or Bluetooth (Configuration done on both sides)
Four basic actions:
a. click (left & right)
b. scroll (up-down & left-right)
c. drag
d. move

Data pack design:

 enum DATA_TYPE
 {
     DATA_TYPE_CLICK_LEFT  = 0,
     DATA_TYPE_CLICK_RIGHT = 1,
     DATA_TYPE_SCROLL_HORI = 2,
     DATA_TYPE_SCROLL_VERT = 3,
     DATA_TYPE_DRAG        = 4,
     DATA_TYPE_MOVE        = 5,
 };

 struct DATA
 {
     enum DATA_TYPE type;
     float velX;
     float velY;
 };

velX and velY are used as distance when type is a movement

Bluez 5

Found a bluez-rfcomm-example repo for Bluez 5 rfcomm server/client example. Whoever created the repo is a hero!!!
Only concern is that Bluez 5 may also require root permission for registration, not sure if there is a way around it.

For me in the future: read and try to implement for linux version.

Also might be worthwhile to update the repo (i.e. a complete refactor of PC code). I would prefer to compile either platform in single cmake file and share most of the code.
And ofc, update the UI as well 🤗
