Abstract: A system is provided that produces haptic effects. The system receives an audio signal that includes a low-frequency effects audio signal. The system further extracts the low-frequency effects audio signal from the audio signal. The system further converts the low-frequency effects audio signal into a haptic signal by shifting frequencies of the low-frequency effects audio signal to frequencies within a target frequency range of a haptic output device. The system further sends the haptic signal to the haptic output device, where the haptic signal causes the haptic output device to output one or more haptic effects.

Abstract: Haptic information in a series of frames of a media file is identified and time stamps corresponding thereto are determined in accordance with information embedded in a tag either preceding or appending the media file. The haptic effect information is automatically synchronized to the media file based on the information in one or more frames of the tag, whereby an actuator outputs the defined haptic effects in the tag in a manner synchronized with corresponding audio and/or video content of the media file.

Abstract: A haptically enabled system is provided. The system receives a haptic effect primitive including a plurality of input parameters that define a haptic effect. The system also receives an input from a sensor that varies over a time duration. The system generates a dynamic haptic effect signal based on the haptic effect primitive and the input, which includes generating a plurality of output parameters including an amplitude of the dynamic haptic effect signal, and varying the amplitude of the dynamic haptic effect signal continuously over the time duration using frequency modulation. The system then applies the dynamic haptic effect signal to an actuator to generate the haptic effect.

Abstract: A haptic conversion system is provided that intercepts frames of audio data, such as a digital audio signal, converts the frames into a haptic signal, and plays the created haptic signal through an actuator to produce haptic effects. The haptic signal is based on a maximum value of each audio data frame, which defines a magnitude of the haptic signal. The haptic signal is applied to the actuator configured to receive the haptic signal, where the actuator utilizes the haptic signal to generate the one or more haptic effects.

Abstract: The disclosure relates to systems and methods of providing haptic feedback based on media content and one or more external parameters used to customize the haptic feedback. The system may modify or otherwise alter haptic feedback that is determined using the media content alone. In other words, the system may use both the media content and the external parameters to determine haptic feedback that should be output to the user or others. The external parameters may include, for example, sensor information, customization information, and/or other external parameters that may be used to customize the haptic feedback.

Abstract: Systems and methods for mapping message contents to virtual physical properties for vibrotactile messaging are disclosed. For example, one disclosed method includes the steps of displaying a first visual representation of a virtual message object having an associated virtual physical parameter at a first device, generating a haptic effect based on the virtual physical parameter at the first device, and sending a message to a second device, the message being configured to display a second visual representation of the virtual message object at the second device and generate the haptic effect based on the virtual physical parameter at the second device.

Abstract: A system is provided that controls an offline haptic conversion. The system receives an input from a source. The system further converts the input into haptic signals. The system further encodes the haptic signals. The system further stores the haptic signals within the source, where the haptic signals are combined with the input within the source. Alternately, rather than encoding the haptic signals and storing the haptic signals within the source, the system handles the haptic signals separately, independent of the source.

Abstract: A system generates haptic effects using at least one actuator and at least one speaker. The system receives a high definition (“HD”) haptic effect signal and a corresponding audio signal if audio is to be played. The system generates a standard definition (“SD”) haptic effect signal based at least on the HD haptic effect signal, and generates an audio based haptic effect signal based at least on the HD haptic effect signal. The system mixes the audio signal and the audio based haptic effect signal, and then substantially simultaneously plays the SD haptic effect signal on the actuator and plays the mixed signal on the speaker.
