Abstract

Optimal target size has been studied for touch-GUI design. In addition, because the degree of risk for tapping unintended targets significantly affects users' strategy, some researchers have investigated the effects of margins (or gaps) between GUI items and the risk level (here, a penalty time) on user performance. From our touch-pointing tasks in grid-arranged icons, we found that a small gap and a long penalty time did not significantly change the task completion time, but they did negatively affect the error rates. As a design implication, we recommend using 1-mm gaps to balance the space occupation and user performance. We also found that we could not estimate user performance by using Fitts' and FFitts' laws, probably because participants had to focus their attention on avoiding distractors while aiming for the target.

Towards More Practical Spacing for Smartphone Touch GUI Objects Accompanied by Distractors
ISS '19: Proceedings of the 2019 ACM International Conference on Interactive Surfaces and Spaces

To achieve better touch GUI designs, researchers have studied optimal target margins, but state-of-the-art results on this topic have been observed for only middle-size touchscreens. In this study, to better determine more practical target arrangements ...
Effect of gaps with penal distractors imposing time penalty in touch-pointing tasks
MobileHCI '18: Proceedings of the 20th International Conference on Human-Computer Interaction with Mobile Devices and Services

Targets on touchscreens should be large enough so that they can be tapped by fingers. In addition to the size of a target, properties of unintended targets around the intended target (e.g., margins) could affect user performance. In this study, we ...
Peephole pointing: modeling acquisition of dynamically revealed targets
CHI '08: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems

Peephole interaction occurs when a spatially aware display is moved and acts as a viewport to reveal different parts of the virtual space that cannot all fit within the display at once. We investigate pointing within this peephole metaphor, where the ...
