US Patent 10311686 Automatic and unique haptic notification

Disclosed herein is an apparatus for automatically generating unique haptic effects. An embodiment of the apparatus comprises a haptic actuator. Memory stores a hash function and a haptic control module programmed to generate a haptic control signal related to a hash value generated by the hash function. A controller is communicatively associated with the haptic actuator and the memory. The controller is configured to receive information, execute the hash function on at least a portion of the information to generate the hash value, generate a haptic signal related to the hash value, and control the haptic actuator to generate a haptic effect, the haptic effect related to the hash value and the haptic signal. A method of automatically generating a unique haptic effect also is disclosed.
