Acton, T., Golden, W. & Van der Heijden, H. (2005) Effects Of See-Through Interfaces On User Acceptance Of Small-Screen Information Systems, 13th European Conference on Information Systems, Regensburg, Germany, May 26-28.
Small-screen devices such as mobile phones are increasingly pervasive. Reduced screen areas compromise the ease-of-use of such devices, and consequently, a concern for system designers becomes the maximization of available screen space. On large-screen displays, menus can overlap and obscure others, and be displayed simultaneously to the user. This is generally not the case with small screens: where a user selects from an on-screen menu, that menu must "vacate" the screen before another appears. Menu translucency, where a user can see through an on-screen menu to displayed elements beneath, is a possible solution to small-screen display maximization. Based on experimental evidence with 70 participants, and using an extended Technology Acceptance Model (TAM) this research examines the effect of on-screen translucent menus on perceptions of ease-of- use, usefulness, and enjoyment for a third generation mobile phone prototype user interface. We offer explanations for our findings and discuss implications for practitioners and researchers.
