The effect of sensory feedback on time perception of interface indicator from age difference

Abstract

The aging of the population is an irreversible trend, and the physiological problems caused by aging make the use of mobile devices a challenge. This study started from the placebo theory of human-computer interaction and pointed out that tactile feedback could make users have a positive experience. Based on the attention door model, experiments were conducted to explore whether different types of feedback could reduce the waiting time perception of users. The experiment divided the experimental group and the control group by age, conducted three types of feedback and two tasks. Using the T-test to analyze significance, and then conducted interviews after the experiment to collect qualitative data. The results showed that in short-term tasks, there were significant differences in the types of feedback that include haptic feedback. For the elderly, the addition of haptic feedback might not reduce time perception. However, in terms of preference, the elderly generally liked the type which including haptic and visual feedback. According to the Qualitative result, haptic feedback could make the operation certainly for the elderly.
