ABSTRACT
Mobile phones are often used in situations in which user's attention is diverted away from the screen. Talking on the phone while walking or driving a car is easy, but dialing a number without looking at the screen or keypad is much harder. We developed two different interaction models to support eyes-free use of number dialing task. Speech and non-speech sounds were used as a substitute for visual feedback. We present prototypes of interaction models running in a mobile phone. Results from a usability study showed that audio feedback is efficient and participants preferred a simple interaction model for eyes-free use.

Using mobile phones to interact with tabletop computers
ITS '11: Proceedings of the ACM International Conference on Interactive Tabletops and SurfacesTabletop computers can be used by several people at the same time, and many are likely to be carrying mobile phones. We examine different ways of performing interactions in this multi-device ecology. We conducted a study into the use of a phone as a ...
Distal tactile feedback for text entry on tabletop computers
BCS-HCI '09: Proceedings of the 23rd British HCI Group Annual Conference on People and Computers: Celebrating People and TechnologyIn this paper we present an initial study into the feasibility of using a mobile phone as a personal tactile display when interacting with a tabletop computer. There has been an increase in recent years in large touchscreen computers that use soft ...
Feedback is... late: measuring multimodal delays in mobile device touchscreen interaction
ICMI-MLMI '10: International Conference on Multimodal Interfaces and the Workshop on Machine Learning for Multimodal InteractionMultimodal interaction is becoming common in many kinds of devices, particularly mobile phones. If care is not taken in design and implementation, there may be latencies in the timing of feedback in the different modalities may have unintended effects ...
