Sketch Recognition User Interfaces: Guidelines for Design and Development
Christine Alvarado · 2004
We present a free-sketch recognition-based tool for creat-ing Microsoft Power Point diagrams. Unlike many previous pen-based interfaces, this tool performs aggressive and ro-bust recognition, allowing the user to sketch freely while the system recognizes the sketched diagram and seamlessly im-ports it into Power Point. Although pen-based user interfaces have been developed and studied, little has been said about the user interface issues involved in developing sketch recog-nition user interfaces. We present initial user interface guide-lines for creating sketch recognition user interfaces (SkRUIs) based on informal, iterative user studies of our Power Point tool. Finally, based on our experience, we claim that a num-ber of iterative design techniques developed for traditional user interfaces cannot be readily applied to SkRUIs. We dis-cuss which techniques are best suited to the design and devel-opment of SkRUIs.
