Abstract
The presented study measures JNDs of vibrotactile force amplitudes at nine frequencies in the bandwidth of 5 ... 1000 Hz with 29 subjects taking part in the study. Reference stimuli are placed near the absolute perception threshold of these frequencies, therefore very high discrimination thresholds of 20 dB on average (with a runaway value of 40 dB @ 1000 Hz) are measured. This is in accordance to observations of Weber’s Law for reference stimuli near the perception threshold. Statistical analysis suggests influence of fingertip size on the results, but no influence of fine motor activity (i.e. playing musical instruments, handicraft, computer games) could be asserted with the given dataset. Results can be used to facilitate task-specific design of sensors and actuators in near-threshold contact situations.
