An interactive support tool to convey the intented message in asynchronous presentations

In this paper we introduce an interactive wall-mounted display tool that supports conveying the intended message or ideas in asynchronous presentations. The tool allows to easily record presentations while capturing the richness of the presenter's individual presentation skills and style. The tool records the presentation and organizes it into three information layers (i.e. gesture, sound and visuals), which are first used to segment the presentation into meaningful parts, and later to control the playback of audiovisual presentations. Once recorded, the presentation can be played back, explored and commented using a flexible and intuitive interaction based on hand movements and body position (i.e. proximity). We focus our work on a case study where designers present their mood boards (i.e. collages) to their clients. Evaluations with professional designers show that they are able to use the tool with no prior training, see a practical use of the proposed tool in their design studios, and see gesture trails as a creative tool for expression and aesthetics.
