Mobile phones are widely used all over the world, and with their increasing number of value-added features, they are becoming far more than a mere mobile voice communication device. Rather, they provide a powerful platform for accessing information universally. This paper reports a study which scrutinized users’ preference levels with five new mobile phone design features facilitating universal information access through mobile phones: camera, colour screen, voice-activated dialing, Internet browsing, and wireless connectivity (e.g. Bluetooth, infrared, etc.). The survey study involved college students and investigated the degree to which each of the above features impacts the users’ overall satisfaction and …

Computer users who handle complex tasks like air traffic control (ATC) need to quickly detect updated information from multiple displays of graphical user interface. The objectives of this study are to investigate how much computer users can segment GUI display into distinctive objects within very short glances and whether human perceives complexity differently after different durations of exposure. Subjects in this empirical study were presented with 20 screenshots of web pages and software interfaces for different short durations (100ms, 500ms, 1000ms) and were asked to recall the visual objects and rate the complexity of the images. The results indicate that …
