摘要： Systems and methods for integrating environmental haptic effects in virtual reality are disclosed. One illustrative system described herein includes a sensor for detecting an environmental condition, the environmental condition associated with an environmental haptic effect, and generating a sensor signal. The system also includes a virtual reality display configured to output a virtual reality effect. The system also includes a processor coupled to the sensor and a virtual reality display, the processor configured to: receive the sensor signal, determine a modification to the virtual reality effect based in part on the sensor signal, and transmit a display signal associated with the modification to the virtual reality display. Another illustrative system includes a sensor for detecting an environmental condition, the environmental condition associated with an environmental haptic effect, and generating a sensor signal, and a virtual reality display configured to output a virtual reality effect. The system also includes a processor coupled to the sensor and a virtual reality display, the processor configured to: receive the sensor signal, determine a generated haptic effect based at least in part of the sensor signal that when combined with the environmental haptic effect produces the desired haptic effect, and transmit a haptic signal associated with the generated haptic effect to a haptic output device.

摘要： One illustrative system disclosed herein includes a computing device that comprises a memory and a processor in communication with the memory. The system also includes an xPC target machine that is capable of achieving sampling rates of at least 100 khz and in communication with the computing device and a user device that includes a sensor and a haptic output device. The processor generates a simulate reality environment and determines a haptic effect based on the simulated reality environment or a sensor signal from the sensor. The processor transmits data about a parameter of the haptic effect or the sensor signal to the xPC target machine, which determines the parameter of the haptic effect and generates, in substantially real time, a haptic signal. The xPC target machine transmits the haptic signal to the haptic output device, which is configured to receive the haptic signal and output the haptic effect.

摘要： 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.

摘要： 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.

摘要： Examples of devices, systems, and methods to automatically generate haptics based on visual color features and motion analysis are disclosed. In one example, a video having a plurality of frames is received and masked frames for the video are generated by applying a color mask to the plurality of frames. An event between two of the masked frames is detected and an optical flow estimate is generated for these masked frames. At least one haptic effect corresponding to the event is generated based on the optical flow. The generated haptic effect(s) may be output to a haptic file or a haptic output device, or both.

摘要： A haptically enabled system receives a haptic effect primitive comprising a plurality of input parameters and receives an input from a sensor. The system generates a haptic effect signal from the haptic effect primitive, the haptic effect signal comprising a plurality of output parameters where at least one of the output parameters is varied based on the sensor input. The system then applies the haptic effect signal to an actuator.

摘要： One illustrative system disclosed herein includes a computing device that comprises a memory and a processor in communication with the memory. The processor generates an interactive user interface and obtains an input parameter and a haptic parameter via the interactive user interface. The processor maps the input parameter to the haptic parameter using a mapping algorithm and designs a dynamic haptic effect based at least in part on mapping the input parameter to the haptic parameter. The processor can then generate a plurality of dynamic haptic effects for a plurality of user devices based at least in part on the designed dynamic haptic effect.
