  • Publication number: 20180130320
    Abstract: One illustrative system disclosed herein includes an enclosure configured to define a boundary of a chamber, the chamber including a material, and a flexible layer coupled overtop of the chamber and configured to enclose the chamber. The illustrative system also includes a first actuation device configured to receive a first haptic signal and responsively output a first haptic effect by changing a characteristic of the material to deform the flexible layer. The illustrative system also includes a second actuation device configured to receive a second haptic signal and responsively output a second haptic effect by applying an electrical signal to the flexible layer. The illustrative system further includes a processor in communication with the first actuation device and the second actuation device. The processor is configured to transmit the first haptic signal to the first actuation device and the second haptic signal to the second actuation device.

  • Publication number: 20180122197
    Abstract: A method or system that receives input media including at least video data in which a video event within the video data is detected. Related data that is associated with the detected video event is collected and one or more feature parameters are configured based on the collected related data. The type of video event is determining and a set of feature parameters is selected based on the type of video event. A haptic effect is then automatically generated based on the selected set of feature parameters.

  • Publication number: 20180097734
    Abstract: Some embodiments provide a method for managing traffic in a virtualized environment. The method, in some embodiments, configures multiple edge service gateways (ESGs) executing on multiple host machines (e.g., on a hypervisor) to use a same anycast inner interne protocol (IP) address and a same anycast inner media access control (MAC) address. In some embodiments, ESGs of a logical network facilitate communication between machines connected to the logical network and machines on external networks. In some embodiments, the method configures a set of virtual extensible local area network tunnel endpoints (VTEPs) connected to an ESG to use a same anycast VTEP IP address. The method, in some embodiments, configures a distributed logical router (DLR or DR) to send data packets with destinations outside the logical network from sources belonging to the logical network to the anycast VTEP IP address.

  • Publication number: 20180011538
    Abstract: Embodiments generate haptic effects in response to a user input (e.g., pressure based or other gesture). Embodiments receive a first input range corresponding to user input and receive a haptic profile corresponding to the first input range. During a first dynamic portion of the haptic profile, embodiments generate a dynamic haptic effect that varies based on values of the first input range during the first dynamic portion. Further, at a first trigger position of the haptic profile, embodiments generate a triggered haptic effect.

  • Publication number: 20170287293
    Abstract: A method of generating event identifiers includes receiving sensor information from tracked entities. Based on the sensor information for tracked entities, an event can be determined. An event ID can be assigned to the event based on the type of event that was determined. The event ID can be sent to a haptically enabled device, the device outputting a haptic effect determined from the event ID.

  • Publication number: 20170285750
    Abstract: A system is provided that converts an input, such as audio data, into one or more haptic effects. The system applies a granular synthesis algorithm to the input in order to generate a haptic signal. The system subsequently outputs the one or more haptic effects based on the generated haptic signal. The system can also shift a frequency of the input, and also filter the input, before the system applies the granular synthesis algorithm to the input.

  • Publication number: 20170171135
    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.
