Haptic communication system using cutaneous actuators for simulation of continuous human touch
摘要
說明書
When a cutaneous actuator (e.g., 924A) is weakly activated so that the generated vibrations do not exceed the sensory threshold, the receiving user would not sense the vibration. However, when multiple cutaneous actuators are operated in conjunction to generate vibrations at the same phase, the constructive interference between the vibrations will create regions where the amplitude of the vibrations is above the sensory threshold. For example,
By selectively operating the cutaneous actuators 924A through 924D and/or controlling the amplitude of the generated vibrations, the perceived center location of the vibrations can be moved around. In this way, virtual cutaneous actuators can be created to give the perception of providing more cutaneous actuators than the number of physical cutaneous actuators.
By providing the cutaneous actuators with actuator signals that gradually change over time, a virtual motion can be created. By using the same principle as the virtual cutaneous actuators but changing the amplitude of the actuator signals, the perceived center locations of the vibrations can be moved over time. This creates the sensation of the virtual cutaneous actuators physically moving over a path.
