Since the visually impaired person could not enjoy videos and other digital media thoroughly, in order to extend tactile perception channels for video media, an electrostatic force tactile rendering method for video perception was put forward. Firstly, target pixels of the current video frame were acquired according to the location of the finger, and color information of target pixels were transformed from RGB color model to HSI color model. Then the hue parameter of target pixels was used to map stimuli frequencies of electrostatic force, the intensity and saturation parameters of target pixels were used to map stimuli amplitudes of electrostatic force, and the tactile stimuli signal was composited to render the real-time video. Finally, dynamic color perception experiments and identification of brightness perception experiments were designed. The results show that the proposed method can realize to sense the information of objects in the video, the average accuracy of dynamic identification reaches 90.6%, the average accuracy of color identification reaches 69.4%, and the average accuracy of brightness identification reaches 80.0%. The proposed method can extract the dynamic characteristics of video information effectively and enhance the real-time tactile rendering for video.
