Project Proposal  #1

Title:                                                                             Wearable PC Mouse

Description:

A hand and finger controlled, wireless mouse

Objectives:

To create a wireless mouse that can be used in combination with a wearable computer that requires no additional surfaces for operation

To optimize a mouse for size and use with a portable system

Specifications:

Fairly small hand and finger operated mouse with wireless communication to system

Full mouse functionality

x-y movement

right, left, and double click

vertical (possible horizontal) scrolling

 

Use of standard mouse drivers on CPU for ease of installation on computer
