| DigiPost: Writing on Post-its with Digital Pen to Support Collaborative Editing Tasks on Tabletop Displays (2009) | |||||||||||||||||
Abstract | |||||||||||||||||
| This paper presents DigiPost, a system for collaborative editing around a tabletop display. In DigiPost, a physical posting gesture links a post-it note with a location on the interactive tabletop. The user uses a digital pen to write on paper post-its as text input, and issue gesture-based commands to the document. DigiPost can be further summarized into “4C”: Connect, Control, Combine and Collaborate. It leverages pen-paper interaction as a tangible input in the context of editing a shared environment. Also, postits can be easily passed between co-located users to promote collaboration. We implemented DigiPost into a map annotating task and conducted an informal lab test to collect feedback. The observation from the test revealed the improvements yet to be made. ACM Classification: H.5.2: User Interfaces—Input devices and strategies.
