Creating expository documents with web-based authoring and heads-up capture

Tutorials are one of the most fundamental means of conveying knowledge. Ideally, tutorials not only describe each step with text or via audio narration but show it as well using photos or animation. In most cases, tutorial authors capture media from handheld mobile devices to import into these documents, but increasingly they use wearable devices as well. Here we explore the use of head-mounted capture for authoring tutorials. We have developed a media-capture tool for Google Glass that requires minimal attention to the capture device and instead allows the author to focus on creating the tutorial content. We describe a study comparing standalone (camera on tripod) versus wearable (Google Glass) capture showing that tutorial authors prefer wearable capture devices, especially when recording activities involving larger objects in non-tabletop environments.
