Methods and apparatuses for endstop diminishment solutions in haptically-enabled controller devices

Abstract:

A haptically-enabled controller device comprising a controller body, a user input element, a haptic actuator, and a transmission component is presented. The user input element has a range of motion that extends from a first position to an end stop position. The haptic actuator is configured to output a force or torque. The transmission component comprises an arm connected to the haptic actuator and to the user input element. The arm is configured to transfer the force or torque from the haptic actuator to the user input element with a first multiplication factor when the user input element is at the first position, and to transfer the force or torque from the haptic actuator to the user input element with a second multiplication factor when the user input element is at the end stop position. The second multiplication factor is higher than the first multiplication factor.
