    摘要： A system provides overlaid haptic effects. The system determines a primary content and a primary haptic effect associated with the primary content. The system also determines a secondary content and a secondary haptic effect associated with the secondary content. Subsequently, the system outputs the secondary content concurrently with the primary content, and also outputs the secondary haptic effect concurrently with the primary haptic effect on at least one haptic output device.

    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： Examples of devices, systems, and methods to automatically generate haptics based on visual odometry are disclosed. In one example, a video having a plurality of frames is received and an optical flow estimate between a first frame from the plurality of frames and a second frame from the plurality of frames is created. In this example, the second frame is subsequent to the first frame. An apparent movement of a stationary object between the first frame and the second frame is detected based at least in part on the optical flow estimate in this example and at least one haptic effect corresponding to the apparent movement of the stationary object is generated based at least in part on the optical flow estimate. The generated haptic effect(s) may be output to a haptic file or a haptic output device, or both.
