Using small screen space more efficiently

Abstract

This paper describes techniques for maximizing the efficient use of small screen space by combining delayed response with semi-transparency of control objects ("widgets") and on-screen text. Most research on the limitations of small display screens has focused on methods for optimizing concurrent display of text and widgets at the same level of transparency (that is, both are equally opaque). Prior research which proposes that widgets may be made semitransparent is promising, but it does not, we feel, adequately address problems associated with user interaction with text that is partially obscured by the widgets. In this paper, we will propose that a variable delay in the response of overlapping widgets and text improves the effectiveness of the semi-transparent widget/text model. Our conclusions are based on usability studies of a prototype of an online newspaper that combined transparency and delayedresponse techniques.
