We introduce the Digital Roll, a cylindrical hand-held device wrapped with a curved display, that can be rotated by hand to provide a continuous scrolling of text. We present design considerations for such a device and report on a preliminary experiment designed to assess its acceptance for casual reading, using a simulator. Encouraging results and their implications on the design of the device are then discussed.

In this paper, we focus on the method to explore a different type of auditory progress bar by analyzing the characteristics of the visual progress bar and contexts of auditory application. A scenario of bearing in the forward/reverse modes of digital compass is selected to implement the auditory progress bar. The auditory cues play an interactive role in the bearing that they are altered according to the user's operating behavior. Composed of sound signal and silent pause, the auditory cues are generated from a formula based on the warm/cold metaphor. A method incorporating the foreground/ background sounds is also designed to provide different ranges of progress information/progress update expressed through auditory cues. In this report four versions of auditory cues are presented as the solution to the interactive auditory progress bar and a pilot study is evaluated.
