A fabric-based item such as a fabric glove may include force sensing circuitry. The force sensing circuitry may include force sensor elements formed from electrodes on a compressible substrate such as an elastomeric polymer substrate. The fabric may include intertwined strands of material including conductive strands. Signals from the force sensing circuitry may be conveyed to control circuitry in the item using the conductive strands. Wireless circuitry in the fabric-based item may be used to convey force sensor information to external equipment. The compressible substrate may have opposing upper and lower surfaces. Electrodes for the force sensor elements may be formed on the upper and lower surfaces. Stiffeners may overlap the electrodes to help decouple adjacent force sensor elements from each other. Integrated circuits can be attached to respective force sensing elements using adhesive.

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.
