Abstract: One illustrative system disclosed herein includes a processor configured to determine a haptic effect, wherein the haptic effect includes a static ESF effect or a confirmation ESF effect; and transmit a haptic signal associated with the haptic effect. The illustrative system also includes an ESF controller in communication with the processor, the ESF controller configured to receive the haptic signal, determine an ESF signal based at least in part on the haptic signal, and transmit the ESF signal. The illustrative system further includes an ESF device in communication with the ESF controller, the ESF device including an ESF cell and configured to receive the ESF signal and output the haptic effect.

Abstract: 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.

Abstract: Systems and methods, by which a sender can deliver haptic messages to selected recipients within a larger group of recipients that are otherwise receiving a common message, are disclosed. The haptic messages can be individualized according to a recipient's profile, preference, and/or relationship with the sender. The haptic message can be created by the sender or selected from a pre-existing library of messages, and can be delivered automatically or assigned by the sender. The haptic messages can be dynamically changed in response to haptic feedback and supplemental data collected from the recipients that is used to update preferences and profiles of message recipients.

Abstract: In aspects, methods and apparatus are provided for generating a haptic effect for a three-dimensional (3D) environment that is experienced virtually by a user. The methods may be performed by a processor, and includes receiving media data that describes the 3D environment, wherein the media data includes haptic data which describes a haptic characteristic associated with at least one object, structure, or event in the 3D environment. The method further includes performing a haptic decoding operation and a haptic rendering operation. The decoding operation may include extracting the haptic data from the media data. The haptic rendering operation may include generating a drive signal and communicating the drive signal to a haptic output device to cause the haptic output device to generate a haptic effect at a user peripheral device. Numerous other aspects are provided.
