Multifunctional user interface implementation details and evaluation

This paper describes in detail the implementation of the multimodal user interface for people with disabilities. The user interface can be used with multiple sensors such as eye tracker, brain wave scanner, speech recognizer and sip/puff device. The system makes it possible to use multiple sensors simultaneously or disable some sensors. New sensors can be integrated without changing other components of the system. We evaluated the performance of the system in the text input task. The results showed increased performance when using multiple sensors simultaneously.
