Sun dial: exploring techno-spiritual design through a mobile islamic call to prayer application.

We present the design and formative evaluation of Sun Dial, an application that supports Muslims' prayer practices. We report on a study that involved identifying prayer as an activity that can be supported with technology; the development of a prototype; and a short-term evaluation of Sun Dial conducted with our local Muslim community. In addition to presenting a novel design idea, our case study contributes to the growing corpus of research examining technology and religion.
