Abstract
A haptic device with a row of 4 solenoids was used to present 7 kinds of pattern stimuli to the forearm. Patterns were uniquely named (e.g. “choppy-motor”), with 3 variants per pattern, designed to be “bad”, “moderate”, and “good” representations of the verbally-announced sensation. Participants were asked to rank each pattern on a 5-point Likert scale, ranking how well a sensation corresponded to its name. Each participant completed two trials, separated by a 5-min break, ranking the 21 randomized pattern variants twice. The results show general likability for most of the “good” variants of the patterns. Pattern likability increased between trials, indicating that increased exposure to this modality may increase believability of patterns. Data shows a positive, near linear relationship between pattern variant quality and participant’s rankings, indicating that participants can distinguish accurate patterns from inaccurate ones.
