Effects of Age on Smartphones Based on Eye-Movements and gestures

The aim of this work is to provide an insight into the effects of user age on interactions with smartphones and tablets applications. The study considered two interaction methods to investigate the effects of user age on the usability of smartphones and tablets of different sizes: 1) eye-movements/browsing and 2) touch-gesture interactions. In eye movement studies, an eye tracker was used to trace and record users¿ eye movements which were later analysed to understand the effects of age and screen-size on browsing effectiveness. Whilst in gesture interactions, an application developed for smartphones traced and recorded users¿ touch-gestures data, which were later analysed to investigate the effects of age and screen-size on touch-gesture performance.
