Description: Temporary mutism may arise as a result of selected medical procedures or disease conditions. The inability to communicate not only places additional stress on patients, but on their families and health care providers. Aside from health related issues, compromised communication is the most significant challenge reported by intubated patients. A non-contact augmentative and alternative communication (AAC) aid has been developed to alleviate this problem. The system does not place any sensors on the user, is very easy to learn and uses simple gestures as a means of interaction. A prototype is presented and various strategies are proposed to enhance human-computer interaction, for example, via the layout of the graphical user interface, the selection criteria, speed and menu organization. In addition, as a preliminary step towards eye-based communication, an algorithm for search space reduction to facilitate automatic face detection has also been developed.
