Focus of this study
The proposal
Gesture Interface Example
Article's Aim
Conventional Auditory Feedback
Issue with transitional auditory feedback for gestural interface
Solution
Preemptive Auditory Feedback
Another Solution
Continuous Auditory Feedback
When it comes to the touching gesture, finding the location of the touch surface is a difficult task for the user
Study Design
Results
The difference in selection times between the transitional auditory feedback and visual-only feedback
conditions was not significant
The preemptive auditory feedback did not yield significant difference in selection time when compared with
visual-only and transitional auditory feedback conditions, indicating that participants selected slightly faster
when using continuous auditory feedback and depth auditory feedback
Accuracy
participants selected more accurately when using preemptive auditory feedback and depth auditory feedback
Overall, depth auditory feedback gave the best performance, achieving the highest accu- racy and the quickest
selection time
It was the only feedback that yielded significantly better performance than both visual-only feedback and
conventional or tran- sitional auditory feedback
The mean selection time of the transitional auditory feedback condition was 2.76 seconds, 4.4 percent faster than the
visual-only feedback
both the continuous and depth auditory feedback conditions showed much larger and statistically significant improvements in the mean selection time,
resulting in 13.6 and 15.5 percent increases, respectively
Continuous Auditory Feedback
Depth Auditory Feedback
The mean selection accuracy of the visual-only feedback condition was 90 percent; for the transitional auditory feedback condition, it was 89.5 percent, which was close to the visual-only feedback condition
Results
The mean selection accuracy of the visual-only feedback condition was 90 percent; for the transitional auditory feedback condition, it was 89.5 percent, which was close to the visual-only feedback condition
