Web Touchpad

Turn any device with a web browser into a wireless touchpad and keyboard for your computer.

This application runs a lightweight web server on your host machine. Connecting to it from another device on the same network (like a phone or tablet) presents a web interface that functions as a remote touchpad.

Features

• Remote Mouse Control: Smooth mouse movement simulation.
• Click Support: Left and Right mouse clicks.
• Two-Finger Scrolling: Natural vertical scrolling.
• Basic Keyboard Input: Send keystrokes from the web interface.
• Adjustable Sensitivity & Acceleration: Fine-tune pointer speed, acceleration curves, precision mode, inertia, and edge damping via constants in the source code (src/main.rs) for a personalized feel.
• Cross-Platform: Runs on Windows, macOS, and Linux (wherever Rust and enigo are supported).
• Zero Client Installation: Only requires a modern web browser on the remote device.

Prerequisites

• Rust: Install Rust and Cargo (The Rust toolchain) from https://rustup.rs/.

Building

1. Clone the repository:

   git clone https://github.com/ycn/web_touchpad.git
   cd web_touchpad

2. Build the release executable:

   cargo build --release

   The executable will be located at target/release/web_touchpad (or target\release\web_touchpad.exe on Windows).

Running

1. Copy Static Files: Ensure the public directory (containing index.html, CSS, and JS files) is placed in the same directory as the compiled executable (web_touchpad or web_touchpad.exe).

2. Run the Executable:

   • On Linux/macOS: ./target/release/web_touchpad
   • On Windows: .\target\release\web_touchpad.exe

   The server will start and listen on 0.0.0.0:8088 by default.

Usage

1. Find the local IP address of the computer running the web_touchpad server.
   • macOS: ipconfig getifaddr en0 (or en1 for Wi-Fi) in the terminal.
   • Linux: ip addr show in the terminal.
   • Windows: ipconfig in Command Prompt.
2. On your remote device (phone, tablet, another computer), open a web browser.
3. Navigate to http://<SERVER_IP_ADDRESS>:8088 (replace <SERVER_IP_ADDRESS> with the actual IP address you found).
4. The web touchpad interface should load. Use it to control the mouse and keyboard of the server computer.

Configuration / Tuning

Pointer behavior (acceleration, precision, inertia, scrolling) can be fine-tuned by modifying the const values within the process_mouse_events function in src/main.rs. Recompile the application after making changes.
