    Abstract: A method of generating a haptic effect on a linear resonance actuator (“LRA”) having a resonant frequency includes receiving a haptic effect signal for the haptic effect, where the haptic effect comprises a desired frequency that is off-resonant from the LRA. The method further includes generating a first sine wave at the desired frequency and generating a second sine wave at or near the resonant frequency. The method further includes combining the first sine wave and the second sine wave to generate a drive signal.

    Abstract translation: 在具有共振频率的线性共振致动器（“LRA”）上产生触觉效果的方法包括接收用于触觉效果的触觉效果信号，其中触觉效果包括与LRA非共振的期望频率。 该方法还包括以所需频率产生第一正弦波并在谐振频率处或附近产生第二正弦波。 该方法还包括组合第一正弦波和第二正弦波以产生驱动信号。

    Abstract: A method for encoding haptic information inside a multi-media file having content includes changing a portion of the content in the multi-media file, and adding the haptic information to the changed portion of the content, the haptic information corresponding to a haptic signal for generating a haptic effect upon playback of the multi-media file. A method for decoding haptic information from inside a multi-media file having content includes locating the haptic information inside the multi-media file, and generating a haptic signal based on the located haptic information during playback of the content of the multi-media file. A method includes receiving a multi-media signal comprising an audio signal and a haptic signal with a receiver of a haptic device, and outputting a haptic effect with a haptic output device of the haptic device based on the haptic signal in the multi-media signal.

    Abstract translation: 一种用于对具有内容的多媒体文件内的触觉信息进行编码的方法包括改变多媒体文件中的内容的一部分，并将触觉信息添加到内容的改变部分，触觉信息对应于触觉信号， 在播放多媒体文件时产生触觉效果。 一种用于从具有内容的多媒体文件内部解码触觉信息的方法包括将触觉信息定位在多媒体文件内，以及在播放多媒体文件的内容期间基于所定位的触觉信息生成触觉信号。 一种方法包括：利用触觉装置的接收器接收包括音频信号和触觉信号的多媒体信号，并且基于多媒体信号中的触觉信号，用触觉装置的触觉输出装置输出触觉效果 。

    Abstract: A system receives a multiplexed signal with two or more different types of haptic signals encoded therein. Each type of haptic signal represents a haptic effect for different types of haptic output devices. The system determines a target haptic output device located on a haptic playback device. The system demultiplexes the multiplexed signal into at least the type of haptic signal corresponding to the target output device. The system provides the demultiplexed haptic signal to the target haptic output device.

    Abstract translation: 系统接收具有在其中编码的两种或多种不同类型的触觉信号的复用信号。 每种类型的触觉信号表示不同类型的触觉输出设备的触觉效果。 该系统确定位于触觉回放装置上的目标触觉输出装置。 该系统将复用的信号多路复用为至少对应于目标输出设备的触觉信号的类型。 系统将解复用的触觉信号提供给目标触觉输出设备。
