Motion Mouse

Motion Mouse uses a microcontroller and its built-in accelerometer, along with an external IR array sensor and a haptic driver, to allow you to control your computer's cursor with hand/wrist motions and gestures.

Motion Mouse was built for Northwestern University's COMP_ENG 346: Microprocessor System Design course in Fall 2023.

Software

• Onboard Software that runs on the microcontroller
• Interaction Driver that runs on the computer

Hardware

Models

• Custom-built 3D-printed enclosure

Products

• micro:bit v2 with serial connection to computer
• SparkFun Qwiic micro:bit Breakout (we used one with headers, but the headers were left unused)
• SparkFun Grid-EYE Infrared Array Breakout - AMG8833 (Qwiic)
• SparkFun Qwiic Haptic Driver - DA7280
• Qwiic Cables (various lengths, minimum 2)
• Sport Bands compatible with Apple Watch (or similar)

Setup

1. Connect the micro:bit breakout to the micro:bit.
2. Connect the infrared array breakout to the micro:bit breakout via a Qwiic cable.
3. Connect the haptic driver to the micro:bit breakout via a Qwiic cable.
4. Connect the micro:bit to the computer via USB.
5. Load the onboard software onto the micro:bit.

Usage

1. Connect the micro:bit to the computer via USB.
2. Run the interaction driver on the computer.
