ABSTRACT
The new forms of interaction being devised for small mobile devices have required designers to re-visit basic principles for user interface design. One of these is the notion of mode. For example, when a key is pressed how will the user know whether the letter displayed will be in upper- or lower-case. An experiment is described in which users have to learn to use a new device where this is an issue. Results show that users are influenced by the case of letters in the prompt.

Will it be a capital letter: signalling case mode in mobile phones
While there are well established guidelines for interaction via mouse and keyboard, new forms of interaction being devised for small handheld devices have yet to be standardised. There is a case for re-visiting basic principles for user interface design ...
Investigating Cross-Device Interaction between a Handheld Device and a Large Display
CHI '17: Proceedings of the 2017 CHI Conference on Human Factors in Computing SystemsThere is a growing interest in HCI research to explore cross-device interaction, giving rise to an interest in different approaches facilitating interaction between handheld devices and large displays. Contributing to this, we have investigated the use ...
Shorthand writing on stylus keyboard
CHI '03: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsWe propose a method for computer-based speed writing, SHARK (shorthand aided rapid keyboarding), which augments stylus keyboarding with shorthand gesturing. SHARK defines a shorthand symbol for each word according to its movement pattern on an optimized ...
