Risk Reduction in Texting While Walking with an Umbrella-Typed Device for Smartphone

摘要

It is widely known that texting while walking is a dangerous behavior. To reduce the risks, we proposed an umbrella-typed device, called ii-kasa to manipulate smartphones. In this paper, we investigated whether ⅱ-kasa reduce the risks in texting while walking. In the experiment, we recorded the gaze patterns using the eye-mark recorder. As the results, the average time and its variance of the eye fixations with ⅱ-kasa were smaller than the ones of the smartphone. The results also showed that the participants in the ii-kasa condition watched the broader areas of their circumstances and paid more attention to their circumstances than in the smartphone condition. These results indicate that ⅱ-kasa makes the risks of texting while walking and human cognitive loads reduce.
