摘要

A haptic communication device includes an array of cutaneous actuators to generate haptic sensations corresponding to actuator signals received by the array. The haptic sensations include at least a first haptic sensation and a second haptic sensation. The array includes at least a first cutaneous actuator to begin generating the first haptic sensation at a first location on a body of a user at a first time. A second cutaneous actuator begins generating the second haptic sensation at a second location on the body of the user at a second time later than the first time.

說明書

Further, each of the channels in the embodiment of FIG. 10E has the following center frequencies in kHz: 0.3876, 0.6891, 0.9905, 1.2920, 1.4212, 1.5073, 1.6365, 1.7657, 1.8949, 2.0241, 2.1964, 2.3256, 2.4979, 2.6701, 2.8424, 3.0577, 3.2730, 3.4884, 3.7037, 3.9190, 4.1774, 4.4358, 4.7373, 4.9957, 5.3402, 5.6417, 5.9862, 6.3308, 6.6184, 7.1490, 7.2366 and 8.0104. Each dominant frequency in the speech signal 216 is mapped to the channel with the closest center frequency.

FIG. 10F is a flowchart illustrating a process of performing haptic communication using selective dominant frequencies, according to one embodiment. The speech source 318 receives the voice signal from a source, and then generates 1062 a digitized speech signal. The digitized speech signal is segmented 1064 into a plurality of frames.

The segmented frames are then processed by performing 1066 Fast Fourier Transform on each frame. Then, the speech source 318 detects 1068 a predetermined number of dominant frequencies with highest peak amplitudes in the result of the FFT. Spectral estimation techniques other than FFT may be applied to the speech source 318 to generate a frequency domain spectrum. The speech source 318 sends 1070 dominant frequency information and the frame information as the speech signals to the signal generator 800.

The signal generator 800 receives 1072 the dominant frequency information and the frame information from the speech source 318. Then the signal generator 800 pre-processes 1074 the dominant frequency information and the frame information by adjusting the length, sequence or overlapping of the frames.
