Authoring a sensor-based interaction comprises three steps: choosing and connecting the appropriate hardware, creating application logic, and specifying the relationship between sensor values and application logic.
This paper contributes techniques for enabling a wider audience of designers and application programmers to turn
raw sensor data into useful events for interaction design through programming by demonstration. It introduces a
rapid prototyping tool, Exemplar.
