Vibro-tactile displays, such as mobile phones and game controllers, have been rapidly brought into every day life. Although, in such displays, vibrations are presented in a successive manner, little research has focused on the perceptual features for the successive vibrations. In this study, we investigated numerocity perception for the vibrations (capability of vibration counting), and compared the performance with that for auditory stimuli. Specifically, we rapidly presented vibration or sound stimuli at constant intervals, and asked participants to answer perceived number of the stimuli. The results revealed perceptual capabilities of counting in each modality. |
