Many situations require precise cursor control but make using a physical mouse impractical—whether working from a hotel room, giving a presentation, or using a phone as a primary device. While touchscreens exist, they lack the precision needed for detailed tasks like graphic design or spreadsheet work. One way to address this could be creating an iOS app that turns a smartphone into a virtual Bluetooth mouse, using the rear camera to track movement on any flat surface and sending cursor inputs via Bluetooth.
The app would use the phone's camera to detect movement relative to a desk or table, translating it into cursor movements. The screen would display virtual buttons for left/right clicks and scrolling. Since iOS supports Bluetooth HID profiles, the phone could appear as a standard input device to computers, tablets, or smart TVs without additional drivers. Advanced features might include:
Unlike existing apps that use touchscreen swipes or accelerometer-based motion, this approach would mimic a physical mouse more closely by tracking actual surface movement.
This could be particularly useful for:
Since most people always have their phones with them, this solution would provide mouse-like functionality without requiring additional hardware. It could also be more customizable than physical mice, allowing users to adjust tracking speed, button mappings, and gestures.
A minimal version might start with basic surface tracking and Bluetooth connectivity, then expand with features like scroll functionality (using the phone's gyroscope) and multi-surface calibration. Testing would be crucial for:
If successful, this could offer a convenient middle ground between touch controls and carrying a separate mouse—especially in mobile or temporary work setups.
