摘要: Mobile touch devices have become increasingly popular, yet typing on virtual keyboards whilst walking is still an overwhelming task. In this paper we analyze; firstly, the negative effect of text-input performance, particularly users' main difficulties and error patterns. We focused our research thumb typing, since a commonly used technique to interact with interfaces. Secondly, analyze how these effects can be compensated by two-hand interaction increasing target size. asked 22 participants input text under three mobility conditions (seated, slow walking, normal walking) hand (one-hand/portrait, two-hand/portrait, two-hand/landscape). Results show that independently condition, significantly decreased quality, leading specific Moreover, it was shown size compensate while does not provide additional stability or accuracy. finish implications for future designs.
