Abstracts

Purpose: SGD interface design such as symbol format and location can increase required operational skills to help reduce device abandonment. The goal of this study was to determine effects of animation within different grid layouts. Method: Effects on response latency and identification accuracy were examined within a 2 x 2 counterbalanced factorial design and analyzed through a 2 x 2 repeated measures ANOVA for 42 adults without disabilities. Results: A Tukey’s post-hoc analyses showed a medium to large significant interaction for all dependent variables. Specifically, participants had increased accuracy in the LC-A condition, reduced average response latency by 2.36 seconds and increased speed by the 4th trial. Conclusion: Animation was beneficial in the location-centered grid, increasing accuracy and reducing response time. These findings add to evidence for the benefits of animation to reduce cognitive load, but future research is required to study these effects with other stakeholder populations.
