Usability and Acceptance in Small-Screen Information Systems (PDF)

A scholarly paper on small screen Usability in PDF format ...

"The small screen sizes of mobile phones can create problems for users. There is a need for acceptable user interfaces
that enable a better, more maximised use of the limited screen size while still providing high levels of usability. One
method of maximising a limited display area is translucency. To examine the effect of translucency on interface
usability we created a fully functioning simulation of a third generation mobile phone user interface, containing a
translucent menu system. In this study translucency was implemented at 50% alpha, and two menu levels deep.
Objective and subjective aspects of usability and acceptance were gathered. Within the focus of the research the study
yielded interesting findings positively relating translucency to perceived usability and measures of acceptance of small
screen information systems. This paper presents the results of this study, and presents avenues for continuing research
arising from the findings."   continued ...   (Via National University of Ireland)
