This paper reports a noble instrument that helps physically disabled people to access computers. There have been numerous attempts to develop such a methodology, but most of them require an additional space for workstation often including access program installation. The additional space also needs to be carefully designed to consider each specific disabled area. This study aims to develop a system that removes the spacial limitation by putting the integrated computer interface using the wheelchair controller. The implementation of the computer workstation is performed by utilizing an USB interface. The developed equipment will take an important role to support various social lives for the users and eventually to improve their quality of life.
