H79.2490 Lecture 4 Credits
Instructor(s): Brumback, Schneider
This class focuses on the unsung hero in physical computing – the switch – and the potential applications beyond it’s typical ‘on or off’ role. We will examine a variety of switches and contexts in which they’re used, particularly in assistive technology, where they serve a crucial role in communication. We will begin by looking at the role of the switch in our life, and its integral role in nearly everything we do. We will then survey and study the use of switches in assistive technology, and consider how the interface, input and feedback may be enhanced and improved to support more responsive, expressive communication. We will then develop our own switches, designed to facilitate communication, which can be adapted to a variety of uses and user needs. We will also study the “back-end” of the switch, in order to facilitate understanding and innovation in switch development. Students will learn how to interpret data from switches, covering topics such as ranging, pattern recognition, responsiveness, and de-bouncing.
