Keyboard and Mouse
Advantages and Disadvantages of the Combimouse
We have constructed a working prototype. Several people have used and evaluated the prototype including a typing teacher. It is clear that the system is convenient and exciting to use.
Other integrated keyboard and pointing systems do not match the performance of the ubiquitous mouse. The pointing stick is prone to muscle tremor and other problems ( see web link to Mithal/Douglas), while the touchpad is inaccurate. Invariably people prefer using a mouse when working on notebook computers.
We have written a program to assist in comparing the speed performance of two mice. For the test shown in Figure 1 the times recorded in the left list were for the combination keyboard/mouse.

The values in the right list were for a Microsoft Intellimouse with Intellieye. To download the program click here (26KB).
