Toolscape

Video tutorials on the web have gained popularity in various domains, but most video repositories are not designed to support the unique content and structure of how-to videos. Learners face difficulty in finding relevant videos and applying the skills embedded in a video clip. We introduce ToolScape, a video browsing interface with a storyboard summarization and an interactive timeline. It allows learners to quickly scan, filter, and review multiple videos without having to play them. Learners can also jump to or repeat a particular step within a clip by clicking interactive indices on the timeline. In a within-subjects study where participants engaged in end-to-end design tasks with ToolScape and a control interface based on YouTube, the participants using ToolScape rated their design work higher and showed a higher gain in self-efficacy. External raters ranked designs using ToolScape higher.
