The method further comprising selecting a haptic feedback response that can be based at least in part on the amount.
Abstract:
Various implementations include a switch assembly that includes a housing and at least two printed circuit boards (PCBs) that are disposed within the housing and are axially arranged relative to each other. One or more force sensors are disposed on one of the PCBs, and, in some implementations, the one or more force sensors receive force input received by a touch overlay plate. Signals from the force sensors are processed to determine a magnitude, acceleration, and/or location of the force input, and a haptic feedback response is received by the touch overlay plate. The haptic feedback response is based on the force magnitude, acceleration, and/or location of input, according to some implementations. Axially arranging the PCBs reduces the footprint of the switch assembly and allows for the inclusion of more electrical components in the switch assembly, according to some implementations.

Abstract:
Implementations of the present disclosure provide a human interface including a light emitter and a pressure sensitive material. The pressure sensitive material has electrical properties configured to vary in relation to an amount of pressure applied thereto. The light emitter is coupled to the pressure sensitive material, wherein variation of the electrical properties of the pressure sensitive material causes variation of at least one illumination characteristic. Advantageously, the pressure sensitive material provides an additional control component allowing bundling of controls in a simpler interface. At the same time, operation of the human interface in low-light or distracted environments is facilitated and rendered more intuitive by incorporation of the light emitter into its operation.
