Abstract
In a stylus for a display device, the stylus includes: a bearing housing; a roller in the bearing housing; and a first actuator coupled to the bearing housing and configured to apply a pressure against the roller to modulate a friction between the stylus and the roller.
Claims18
A stylus for a display device, the stylus comprising:
- a bearing housing;
- a roller in the bearing housing;
- a first actuator coupled to the bearing housing and configured to apply a pressure against the roller by moving a friction modulator against the roller to modulate a friction between the stylus and the roller,
- wherein the bearing housing comprises a plurality of sections configured to be moved against the roller to modulate the friction between the stylus and the roller;
- and
- an axial actuator coupled to the bearing housing and the first actuator and configured to adjust axial positions of the friction modulator and the plurality of sections simultaneously.

A haptic feedback system, comprising:
- a display;
- and
- a stylus in communication with the display, wherein the stylus comprises:
- a bearing housing;
- a roller in the bearing housing;
- a first actuator coupled to the bearing housing and configured to apply a pressure against the roller by moving a friction modulator against the roller to modulate a friction between the stylus and the roller,
- wherein the bearing housing comprises one or more sections configured to be moved against the roller to modulate the friction between the stylus and the roller;
- and
- an axial actuator coupled to the bearing housing and the first actuator and configured to adjust axial positions of the friction modulator and the one or more sections simultaneously.

A method of generating haptic feedback in a stylus, the stylus comprising:
- a bearing housing;
- a roller in the bearing housing;
- a first actuator coupled to the bearing housing and configured to apply a pressure against the roller by moving a friction modulator against the roller to modulate a friction between the stylus and the roller,
- wherein the bearing housing comprises one or more sections configured to be moved against the roller to modulate the friction between the stylus and the roller;
- and
- an axial actuator coupled to the bearing housing and the first actuator and configured to adjust axial positions of the friction modulator and the one or more sections simultaneously, the method comprising:
- detecting a touch input on a display, the touch input being applied to a touch interface by the roller of the stylus, wherein the roller is in the bearing housing;
- modulating the friction applied to the roller according to the touch input;
- and
- transmitting a signal to the axial actuator coupled to the bearing housing for adjusting an axial position of the bearing housing in the stylus.
