Steuerung von haptischen Empfindungen für Schnittstellenvorrichtungen mit Vibrotaktiler Rückkopplung

摘要

An apparatus comprises an actuator that includes an eccentric mass that is coupled to a rotatable shaft of the actuator which defines an axis of rotation. A circuit is coupled to the actuator, the circuit is configured to produce a control signal such that, when the control signal is received by the actuator. The actuator is configured to produce a force effect having a magnitude and a frequency by rotating the mass about the axis of rotation in a first direction. The magnitude of the vibration is based on a duty cycle of the control signal and independent of the frequency. An obstacle member is coupled to the actuator and includes a compliance portion configured to increase energy in the movement of the mass in a second direction opposite to the first direction when the mass comes into contact with the obstacle member.
