Haptic-feedback content-presentation hardware.
Systems and methods generating a haptic output response are disclosed. Video content is displayed on a display. A location of a user touch on the display is detected while the video content is being displayed. A region of interest in the video content is determined based on the location of the user touch. And a haptic output response is generated to a user. A characteristic of the haptic output response is determined using one or more characteristics of the region of interest.
BACKGROUND (1) Video content is viewed and enjoyed by hundreds of millions of people on a daily basis (e.g., on computers, smartphones, televisions, etc.). The blind or visually impaired, however, encounter challenges when consuming video. Because they cannot fully see the video, other techniques are used to communicate what is occurring in the video. For example, a descriptive audio track may play during different portions of the video to describe the events that are being shown in the video. These techniques, however, interfere with the presentation of the content. For example, the descriptive audio may conflict with the regular audio track for the video, as it is played over the top of the main audio track. SUMMARY (2) According to an embodiment, a method includes displaying, on a touchscreen, a video comprising a video frame and determining, based on a saliency map of the video frame, a region of interest in the video frame. The method also includes detecting a touch on a region of the touchscreen while the video frame is displayed and generating a haptic response in response to determining that the region of the touchscreen overlaps with the region of interest. Other embodiments include an apparatus and a system that perform this method. (3) According to an embodiment, a method includes displaying video content on a display and detecting a location of a user touch on the display while the video content is displayed on the display. The method further includes determining
1. A method comprising: receiving a saliency map of a frame of video content, the saliency map including a plurality of defined regions of interest in the frame of the video content; displaying the video content on a display, wherein the plurality of defined regions of interest of the saliency map correspond to locations on the display; detecting a location of a user touch on the display that overlaps a defined region of interest of the plurality of defined regions of interest of the saliency map while the frame of the video content is displayed on the display; determining a region of interest of the plurality of defined regions of interest in the video content based on the location of the user touch and the saliency map; and generating a haptic output response to a user, wherein a characteristic of the haptic output response is determined by one or more characteristics of the region of interest. ||
9. A system, comprising: a display; at least one hardware processor; and at least one non-transitory memory carrying instructions that, when executed by the at least one hardware processor, cause the system to: receive a saliency map of a frame of video content, the saliency map including a plurality of defined regions of interest in the frame of the video content; display the video content on the display, wherein the plurality of defined regions correspond to locations on the display; detect a location of a user touch on the display while the frame of the video content is displayed on the display; determine a particular region of interest of the plurality of defined regions of interest in the video content based on the location of the user touch overlapping the particular region of interest as defined in the saliency map; and generate a haptic output response to a user, wherein a characteristic of the haptic output response is determined by one or more characteristics of the region of interest. ||
17. At least one non-transitory computer-readable medium carrying instructions that, when executed by a computing system, cause the computing system to perform operations comprising: receiving a saliency map of a frame of video content, the saliency map including a plurality of defined regions of interest in the frame of the video content; displaying the video content on a display, wherein the plurality of defined regions of interest correspond to locations on the display; detecting a location of a user touch on the display that overlaps a defined region of interest of the plurality of defined regions of interest of the saliency map while the frame of the video content is displayed on the display; determining a region of interest of the plurality of defined regions of interest in the video content based on the location of the user touch and the saliency map; and generating a haptic output response to a user, wherein a characteristic of the haptic output response is determined by one or more characteristics of the region of interest.
