Making Video Interaction on Touch Devices Consistent

Article from

screenshot1The video players on smartphones and tablets typically use seeker-bars for temporal navigation in videos. In order to jump to different positions in the video you simply have to drag the seeker-bar. However, we argue that this interaction concept is inconsistent to usual interaction with other media on touch devices. For example, in a photo collection you perform horizontal wipe (i.e., drag) gestures in order to browse through all photos of the collection. Similarly, when scrolling through documents or presentation slides, you perform horizontal (or vertical) wipe gestures. Hence, we propose to use such wipe gestures also for navigation in video. Our work combines the ideas proposed earlier by Huber et al. and Hürst et al. in order to allow flexible navigation within a single video but also in a video collection. More details can be found in the preprint of our paperVideo Navigation on Tablets with Multi-Touch Gestures”, to be presented at the 3rd International Workshop on Emerging Multimedia Systems and Applications (EMSA) at the IEEE International Conference on Multimedia & Expo (ICME) in July 2014 in Chengdu, China. Ourprototype is also available on the App Store on iTunes for the Apple iPad (many thanks to Kevin Chromik for the implementation and evaluation)!
