— The increasing availability of sensing devices has made the possibility of context-aware pervasive computing applications real. However, constructing this software requires extensive knowledge about the devices and specialized programming languages for interacting with them. While the nature of pervasive computing lends users to demand individualized applications, complexities render programming embedded devices unapproachable. In this paper we introduce the SEAP (Sensor Enablement for the Average Programmer) middleware which applies existing technologies developed for web programming to the task of collecting and using sensor data. We show how this approach can be used to create new applications and to update existing web applications to accept sensor data.
