Abstract
In Experiment 1, participants performed to classify an image with only a letter label (VL) and a picture with a letter label and tactile dots (TL) shown on the display. There was no significant difference in classification time and correct response rate between the conditions, indicating that tactile dots as visual labels alone had no significant effect on the classification task. In Experiment 2, participants classified the pouch containers used for the images in Experiment 1. The results showed no significant difference in the percentage of correct responses. Still, classification time was significantly shorter in the TL than in the VL. It indicates that tactile dots used as visual and tactile cues reduced classification time.
