Our project is to improve a workspace and computer mouse that can be controlled by mouth for an elderly woman who only has mobility from the neck up.

On Thursday, September 8, 2011, we met with our project contact, Ms. Smiley. The issues seen were non-user friendly devices, including a mouth piece that is hard to control, an unmanageable workspace, and a cumbersome mouse. As it is, she cannot use the shift and controls keys on her keyboard as well as drag the mouse. The holder for her mouthpiece is unsturdy and at an uncomfortable height for placing and picking up the mouthpiece. Also, anytime her table/workspace is moved, all of the components have to be put back exactly like before. In addition, the workspace is difficult to move. We intend to improve these devices so that they are accessible and easy to use.
-Be controlled only using the woman's mouth.
-Accessible using only slight movement of the neck.
-Laptop and mouse at an adjustable angle.
-Holder that holds and makes the mouthpiece easily accessible.
-Workspace must be easily mobile.
-Be able to use the shift and controls keys.
-Be able to drag the mouse.
-Be able to accomodate more of her needs (ex: extra mouth pieces, phone holder, remote holder, etc.)
-Workspace that is easily broken down and put back together.
The workspace includes several components, including the desk and devices for Ms. Smiley's cell phone, remote, laptop, mouse, and mouthpieces. For each component we have provided different designs.
Laptop & Mouse Devices
Both devices will be created using the same concept; the only difference is in dimensions. Concept ideas similar to pool chairs.
