1. Handy Mouse Handy Mouse Spring Semester 2008 Characterization Presentation Presenting: Gabi Klein & Keren Green Instructor:Ina Rivkin Technion – Israel Institute of Technology Department of Electrical Engineering High Speed Digital Systems Lab

2. Background In order to allow people with motor disabilities, which limits hand usage to use a normal mouse, we design a special clever mouse. In order to allow people with motor disabilities, which limits hand usage to use a normal mouse, we design a special clever mouse. This mouse is a Single Button Mouse, which allows full functionality using a single switch. This mouse is a Single Button Mouse, which allows full functionality using a single switch.
