Abstract
Touch-based input devices, such as a stylus, can receive tactile input from a user. The tactile input functions can be performed by a touch sensor, such as a capacitive sensing device. A touch sensor can be integrated into a stylus in a low profile form. Wireless charging and magnetic coupling with a host device are also facilitated. The stylus can be provided with the above features in a small form factor that improves a user experience with the stylus.
Claims20
A stylus comprising:
- a housing;
- a frame assembly within the housing and comprising:
- a first frame;
- and
- a second frame, wherein the first frame and the second frame are joined together to define a charging window there between;
- and
- a wireless power receiver within the charging window and adjacent to the housing.
4 more elements
A stylus comprising:
- a housing having a longitudinal portion forming a substantially flat exterior surface extending along a length of the stylus, the housing defining a grip region of the stylus;
- multiple stylus magnets for magnetically coupling to corresponding host magnets of a host device, the stylus magnets being within the housing and adjacent to the longitudinal portion;
- and
- a capacitive touch sensor comprising multiple sensing elements distributed circumferentially and longitudinally along an inner surface of the housing at the grip region, wherein a portion of the capacitive touch sensor is positioned radially between one of the stylus magnets and the longitudinal portion of the housing.
1 more element
A stylus comprising:
- a housing;
- a tip moveable with respect to the housing;
- a core insert configured to removably couple to the tip and comprising:
- a proximal electric field generator at a first axial location along the core insert;
- a first distal electric field generator at a second axial location along the core insert;
- and
- a second distal electric field generator at the second axial location along the core insert and radially opposite the first distal electric field generator.
