Haptic communication system using cutaneous actuators for simulation of continuous human touch
摘要
說明書
Similarly, for each amplitude of a set of amplitudes of vibration, the first haptic sensations and the second haptic sensations may be transmitted to each of several participants, where the first haptic sensations and the second haptic sensations correspond to the amplitude. A rating (e.g., pleasantness or continuity of the tactile motion) may be received from each participant for the amplitude. The received ratings may be aggregated to determine a preferred amplitude and frequency set corresponding to a highest rating.
In one experiment, a preferred frequency of the haptic sensations was determined to equal or be greater than 20 Hz. The preferred frequency of the haptic sensations was determined to equal or be less than 70 Hz. A preferred amplitude of the haptic sensations was determined to equal or be greater than 15 dB SL. The preferred amplitude of the haptic sensations was determined to equal or be less than 30 dB SL. In other embodiments, the amplitude of the haptic sensations may lie between 15 dB SL and 30 dB SL.
In one experiment, a preferred region of operation 1568 for the cutaneous actuators was determined from the ratings provided by the participants. The preferred region of operation 1568 included a frequency of 70 Hz and an amplitude of 15 db SL within a usable range of 20-70 Hz and 15-20 dB SL, as depicted in
