Broadly speaking, embodiments of the present techniques provide haptic button assemblies in which the haptic button has a low profile while still providing a satisfying tactile response or sensation to a user. Advantageously, the haptic button assemblies may have a profile that, for example, enables the assembly to be incorporated into the free space along an edge of a portable computing device. The haptic assemblies may, for example, be arranged to move the button perpendicularly with respect to the edge of the device.

Haptic button with SMA

Broadly speaking, embodiments of the present techniques provide techniques for generating haptic feedback or haptic sensations and, in particular, techniques for scheduling such feedback or sensation when there are possibly conflicting requirements for such feedback or sensations.

Scheduling haptic feedback

Broadly speaking, embodiments of the present techniques provide techniques for generating haptic feedback or haptic sensations, and in particular to techniques for outputting haptic feedback which varies depending on the input. The haptic feedback is delivered by a shape memory alloy (SMA) actuator that controls the movement of a component based on the required haptic feedback/sensation.

Haptic feedback generation

Broadly speaking, embodiments of the present techniques provide apparatus and methods for providing haptic feedback, and in particular to user-operated buttons for electrical and electronic products that provide haptic feedback to the user when operated.
