Relationship between Dwell-Time and Model Human Processor for Dwell-based Image Selection

Toshiya Isomoto, Shota Yamanaka, Buntarou Shizuki

We investigated the relationship between dwell-time and the model human processor (MHP). First, we devised an equation that can represent the time taken for recognizing an image based on MHP. Then, we evaluated whether the equation can represent the time and wheter the time estimated by the equation matches the user’s preferred dwell-time. The experiment consisted of two tasks: image selection with a button (button-task) and image selection with a dwell (dwell-task). From the results of the button-task, we found that the equation derived by MHP can estimate the time; the time taken for button selection was 662 ms on average, and the time estimated by the equation was 660 ms on average. Also, we showed that the estimated time represented the user’s preferred dwell-time; all participants in the experiment answered that 500 ms and 600 ms were their preferred dwell-times.
