US Patent 10977910 Tactile outputs for input structures of electronic devices

An electronic device may provide tactile outputs at a tactile output region of the electronic device. The tactile output region of the electronic device may be a surface of an input structure or a surface of an enclosure of the device. Tactile outputs may provide a sustained, physically-based notification of a particular item of interest. The tactile output may alter a physical characteristic of the tactile output region, such as the shape, texture, or density of a portion of the electronic device, in one or more tactile output regions. Furthermore, the tactile notification may provide a notification that is less intrusive and more tunable to user preferences than conventional notifications. The tactile output may be static in that the tactile notification is not transitory and remains throughout the duration of the tactile output. The tactile notification may be dynamic in that it includes motion.
