Elderly User Evaluation of Mobile Touchscreen Interactions

摘要

Smartphones with touchscreen-based interfaces are increasingly used by non-technical groups including the elderly. However, application developers have little understanding of how senior users interact with their products and of how to design senior-friendly interfaces. As an initial study to assess standard mobile touchscreen interfaces for the elderly, we conducted performance meas-urements and observational evaluations of 20 elderly participants. The tasks in-cluded performing basic gestures such as taps, drags, and pinching motions and using basic interactive components such as software keyboards and photo view-ers. We found that mobile touchscreens were generally easy for the elderly to use and a week's experience generally improved their ciency. However, careful observations identified several typical problems that should be addressed in future interfaces. We discuss the implications of our experiments, seeking to provide informal guidelines for lication developers to design bet-ter interfaces for elderly people.
