The Effects of Length and Type on the Recognition of Tactile Line
This study mainly focused on the tactual misjudgment of tactile line. In a complete balanced experiment, 15 blindfolded sighted and 15 visual impaired (8 Low Visions, 4 Congenital Blinds, and 3 Late Blinds) subjects were asked to explore and to tell the difference of length from randomly assigned 24 tactile lines. There were some interrupt symbols assigned on the tactile line to simulate the conditions which might happen in the actual map. The factors of those stimuli were line-type (line and arc) and line-length (9 and 11 cm), and the measured variables were total recognition time and the perceptual length deviation. An ANOVA test indicates that the longer line-length level (11 cm) has the significant longer mean recognition time, and it also produces significant larger mean perceptual length deviation which the subjects tend to have overestimate prediction. The results may be applied in the design of tactile map in order to reduce the possible misleading.
