摘要： Systems and methods for multi-level closed loop control of haptic effects are disclosed. One illustrative system for multi-level closed loop control of haptic effects includes a haptic output device configured to output a haptic effect, a sensor configured to sense the output of the haptic output device and generate a sensor signal, and a processor in communication with the sensor. The processor is configured to: receive a reference signal, receive the sensor signal, determine an error based at least in part on the reference signal and the sensor signal, generate a haptic signal based at least in part on the reference signal and the error, and transmit the haptic signal to a haptic output device configured to output a haptic effect based on the haptic signal.

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 of the present disclosure includes a sensor configured to detect a gesture that includes a movement through multiple positions in real space. The multiple positions can include a first position that is distant from a touch sensitive surface and a second position that is closer to the touch sensitive surface than the first position. The system also includes a processor in communication with the sensor. The processor can output a graphical user interface (GUI) that includes multiple available user interface levels. During the gesture, the processor can activate a sequence of user interface levels, where each user interface level in the sequence is selected from among the multiple available user interface levels and is activated at a respective position among the multiple positions in the gesture. The processor can also cause a haptic output device to provide haptic feedback associated with each user interface level.

摘要： A video game system records video gameplay by a player interacting with an endpoint, such as a game controller. The recording includes recording a haptic track of haptic effects generated on the endpoint during the gameplay and recording a video track of video generated during the gameplay. The recording further includes encoding the haptic track with the video track.

摘要： A flexible haptic actuator and corresponding method. The flexible haptic actuator comprises a core formed with a flexible material. The core defines a volume and is bendable. An electrical conductor is coiled around the core and is bendable. A casing surrounds the electrical conductor and at least a part of the core. The casing includes a plurality of flexible sections and a plurality of stiff sections. The casing is bendable. A haptic mass is suspended in the volume, the haptic mass being at least partially formed with a magnetic material. The haptic mass is movable in the volume in response to the electrical conductor generating a magnetic field.

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 haptic conversion system is provided that analyzes an audio signal, generates a plurality of haptic signals based on the analysis of the audio signal, and plays the generated plurality of haptic signals through a plurality of actuators to produce one or more haptic effects. The haptic conversion system maps the generated plurality of haptic signals to the plurality of actuators based on one or more audio characteristics of the audio signal. Each generated haptic signal includes one or more haptic parameters, and is played at its mapped actuator to generate the one or more haptic effects.

摘要： Systems, methods, and computer program products for providing composite haptic effects are disclosed. One disclosed method includes detecting a touch occurring in a touch area when an object contacts a touch surface and selecting a composite haptic effect to generate in response to the touch, the composite haptic effect including at least one surface-based haptic effect and at least one other effect. Based on the selected composite haptic effect, a first haptic signal can be sent to cause an actuator to vary a coefficient of friction of the touch surface and a second actuator can be caused to provide a second haptic output in addition to the variation in the coefficient of friction. The second haptic signal can be sent to a second actuator or the same actuator(s) used to vary the coefficient of friction can generate the second haptic output.

摘要： A method and system for energy savings with silent haptics is presented. A haptically-enabled device includes a processor that executes a haptic track containing haptic instructions. The haptic track is analyzed to determine the presence of a zero-force interval, also known as a silent haptic. The duration of the zero-force interval is determined, and if the duration exceeds a pre-determined threshold, then the system or method enters an energy savings mode. An overhead time associated with the terminating of the energy savings mode is determined. And, the energy savings mode is terminated at the conclusion of the zero-force interval less the overhead time.
