Haptic communication system using cutaneous actuators for simulation of continuous human touch
摘要
說明書
In one embodiment, the different frequencies of haptic output may be targeted towards different sensory cells in the user's skin. In one embodiment, the higher frequency haptic outputs (e.g., 250 Hz), such as the high frequency 1133 haptic output, are targeted towards Pacinian corpuscle cells, while the low frequency haptic outputs (e.g., 30 Hz), such as the low frequency 1131 haptic output, are targeted towards Merkel cells. In such a case, the frequency of the high frequency 1133 haptic output is sufficiently high to trigger response in the Pacinian corpuscle cells and to avoid triggering the Merkel cells, whereas the low frequency 1131 haptic output is of a frequency that triggers the Merkel cells but not the Pacinian corpuscle cells. As Pacinian corpuscle cells (also known as Lamellar corpuscle cells) are sensitive to vibration, while Merkel cells are sensitive to general touch, different types of haptic output can target different mechanoreceptor cells in the user's skin and be associated with different phonemes when converting the input words 1106 to actuator signals 1111 which are used to cause the cutaneous actuators 1104 to generate the haptic outputs.
