TL;DR: A haptic device comprises an actuator and a mass, and is elastically coupled to the mass and/or a base as discussed by the authors, where the actuator has a shaft and the mass has a base.
Patent
Haptic feedback effects for control knobs and other interface devices
TL;DR: In this article, the authors describe haptic sensations for a haptic feedback device and especially for a rotational device such as a knob, which allows easier selection of menu items, menus, values or other options by the user.
Patent
Method And Apparatus For Providing Tactile Sensations
TL;DR: A controller may be employed to receive signals from the input devices and control the actuator as mentioned in this paper, and a variety of feedback types and combinations may be selected, such as the level of pressure placed on the input device, the availability or lack of availability of a function associated with an input device; and the function, menu, or mode of operation associated with a device's activation.
Patent
Haptic shifting devices
TL;DR: In this article, a haptic shift device for use in shift-by-wire systems in vehicles is described, where the shift lever is moveable within a pattern and is blocked from areas outside the boundaries of the pattern.
Patent
Mechanisms for control knobs and other interface devices
TL;DR: In this paper, a rotatable knob with an agate member and a plunger member that engages grooves in the gate member is used to detect a rotational position and a lateral sensor can detect a lateral position of the knob.
