The purpose of this project was to create a low cost, highly functional, and lightweight computer mouse device that could be used with a large range of physically impaired and disabled persons. My design criteria was that this device must cost less than $50, be functional in moving a computer mouse pointer(and also click if needed), and weigh less than 0.5 pounds. I used a microcontroller (with a loaded program), a logic level converter, and a gyroscope/accelerometer combination to create a device that would be able to detect movement of the head or any appendage and convert that data into movement of a computer mouse pointer on screen. I ended up having to use a different gyroscope/accelerometer than the original one that I planned to use as it could not function as a movement oriented device. After finishing the prototype with the working gyroscope/accelerometer I tested the device in order to find areas that needed to be redesigned. After redesigning the device with any areas that I found weak fixed, I retested the device to make sure it was stable. The device proved to be cost efficient, compact, and lightweight and demonstrated a profound ability to work as a computer mouse and possibly therapy device. My next steps would be to test this device with actual physically impaired and disabled patients and then possibly do clinical trials and marketing.
