Abstract

When used to support users with motor impairment, sensor-based interaction devices rely heavily on exploiting the available user movements to work properly. This implies that the design of sensor-based interaction devices depend on proper attending requirements associated with many possible disabilities. As a result, it may be necessary, for a given device, to carry out detailed personalization with respect to adjusting sensors, interaction primitives and mapping to software applications. We propose an architectural approach to support the flexible customization of sensor-based input devices so as to provide a systematic procedure to personalize input devices according to user needs. The architecture defines a model that exploits discrete and continuous input dimensions associated with sensors and allows designing novel input devices. We illustrate the use of the architecture with implementations that exploits accelerometers and gyro sensors in two input devices.
