First Claim
Patent Images
1. An input device configured to receive an input force, the input device comprising:
- an input surface;
a variable response material adjacent the input surface;
a magnetic field source adjacent the variable response material and positioned between the input surface and the variable response material; and
a controller configured to control the magnetic field source;
wherein the magnetic field source is configured to generate a magnetic field to adjust one or more material properties of the variable response material, thereby varying a response of the input surface to the input force.

10. A keyboard input device, comprising:
-
a group of rigid keycaps having input surfaces, the keycaps each being configured to travel in response to an input force, the keycaps each being spaced apart from each other; and a variable response material disposed below each keycap, the variable response material associated with multiple input force response profiles for each input surface; wherein, when variable response material of a particular keycap of the group of rigid keycaps is subject to a magnetic field; a material property of the variable response material changes; and an input force response profile of the input surface of the particular keycap changes. - View Dependent Claims (11, 12, 13, 14, 15)
