Haptic communication system using cutaneous actuators for simulation of continuous human touch
摘要
說明書
In one experiment, when the cutaneous actuators generated haptic sensations including more than one frequency, it was determined that combining equal components of low frequencies and high frequencies (e.g., 20 Hz+250 Hz) rendered the touch less pleasant. However, combining a larger low-frequency component with a smaller high-frequency component (e.g., 20 Hz+70 Hz+250 Hz) was determined to offset the high frequency component and render the touch more pleasant.
In one experiment, lower frequencies (e.g., 20 Hz) were rated positively on the pleasantness scale, i.e., less than 5% of users reported less pleasant sensations. Higher amplitudes were rated less pleasant, i.e., less than 5% of users reported pleasant sensations. Female participants tended to rate the haptic sensations higher on the pleasantness scale.
A preferred region of operation 1568 for the cutaneous actuators 1508 may therefore be constructed in terms of frequency range and amplitude range. In one experiment, frequencies of 20-70 Hz at 15-30 dB SL were determined to be a preferred range 1568 of the parameters.
