Purpose:
This study proposes a novel computer pointing device that uses a commercial numerical keyboard as the input device of the device to help people with disabilities move a cursor to a target quickly, easily and accurately.
Method:
The proposed device adopts a Screen-Partitioning and Coding method and adopts an Auxiliary-Window-Screen program design that provides users with a visual operating environment.
Result:
Three people with disabilities tested the device. In an experiment user-performance was measured and compared with that using mousekeys developed by Microsoft and the two-grade method proposed by Shih. Experimental results reveal that this method enables people with disabilities to operate computer.
Conclusions:
In summary, a novel method is applied to help people with disabilities move a cursor to a target. The proposed device uses a commercial pointing device as the input device, providing users with an inexpensive, flexible and easily maintained computer pointing device. Furthermore, the proposed device adopts the Auxiliary-Window-Screen design to provide the users with a visual operating environment. Experimental results show that the proposed device is superior to those of the previous studies.
