This project will allow a user to wirelessly control a computer via a glove on their hand. Douglas Engelbart at Oregon State College developed the first computer mouse. The usefulness of the mouse has not diminished since it was invented. Alternate forms of the mouse have been created in the past, with the addition of extra buttons and scroll wheels. This project attempts to further alter the concept of a mouse into another form, including various shortcuts to give further control over the computer.

The project entails a single glove incorporating several sensors. The glove will have multiple touch sensors attached, which will add various functions such as mouse clicks, drag and drop, and various other shortcuts. On the computer side, an application GUI will be used to program the sensors to perform specific actions, such as maximizing or minimizing windows. The glove will also include an inertial measurement unit (IMU), which will incorporate a Gyroscope and Accelerometer. This will allow for the user to execute actions on the computer based on rotation or twisting of the hand.

The mouse will be controlled in two ways that is still to be decided. The first way is via the IMU where rotating the hand will allow the user to move the mouse. The second way is via optical sensor that maps the surface it is above to give second by second image capturing, which can then be put through a digital signal processor to see how much the hand has moved since the previous image. Both ways are being researched and the most efficient route will be taken.

Apart from controlling the computer, our efforts will be focused towards incorporating the project with Dr. Hauping Liu’s current projects. Dr. Liu’s team is attempting to map the trajectory of hand travel when mechanics do various actions such as turning a wrench. It is important for them to know how the hand moves and we will use our project to help them achieve their goal. We are in the process of understanding the specific requirements Dr. Liu has to see if it matches with our goals for this project.

This project has a few key focuses that will allow the project to succeed. Our first focus is to make this as cost efficient as possible even though there are no major competitors in the market. Our second focus is to try and make this glove be used on various computers. The last major focus is to integrate our project with Dr. Liu’s research tracking hand movements so it can be instantly beneficial, and have a real-life application in an innovative field.
