Evaluating the Hands-free Mouse Control System: An initial case study

An initial user study evaluating the HAnds-free Mouse COntrol System (HaMCoS) will be presented. The system allows its user to fully operate a Windows (R) PC without, rising the hands. It, requires a special piezo-based input sensor in order to pick up the muscular activity of a single dedicated muscle of the user. The idea is to detect intentional contractions of the monitored muscle and to use this information for emulating a two-button mouse device. In addition, the software frame-work renders any keyboard input unnecessary. so HaMCoS represents a comprehensive input method For persons who are unable to reliably employ the hands (e.g., tetraplegics). The paper will take a closer look at the specifics of the system followed by a discussion of the experiences by potential end users in a first case study.
