Publication number: 20240141562Abstract: A fabric-based item may include a housing that is covered in fabric. Areas of the fabric may overlap input circuitry such as button switches, touch sensors, force sensors, proximity sensors, and other sensing circuitry and may overlap other components such as light-emitting components and haptic output devices. The fabric-based item may include control circuitry that gathers user input from the input circuitry and wireless communications circuitry that the control circuitry uses to transmit remote control commands and other wireless signals in response information from the input circuitry. The fabric-based item may have a weight that is located in the housing to orient the housing in a desired direction when the housing rests on a surface. A movable weight may tilt the housing in response to proximity sensor signals or other input. Portions of the fabric may overlap light-emitting components and optical fiber configured to emit light.Type: ApplicationFiled: January 8, 2024Publication date: May 2, 2024Inventors: Daniel A.
