applications, to be usable by a broader spectrum of the average population, and to function more reliably under realistic and challenging usage conditions. In this paper, we summarize the emerging architectural approaches for interpreting speech and pen-based gestural input in a robust manner--- including

the real-time requirements of HCI. Appearance-based models lead to computationally efficient “purposive” approaches that work well under constrained situations but seem to lack the generality desirable for HCI. We also discuss implemented gestural systems as well as other potential applications of vision-based

Abstract. In this paper we present a new algorithm for automatic recognition of hand drawn sketches based on the Levenshtein distance. The purpose for drawing sketches in our application is to create graphical user interfaces in a similar manner as the well established paper sketching. The new

performance? And how does the paper interface work in a typical use scenario? To answer these questions, we conducted two empirical experiments on a generic pen gesture based command system, called PapierCraft [Liao, et al., 2008], for paper-based interfaces. With it, people can select sections of printed

We present LogicPad, a pen-based application for boolean algebra visualization that lets users manipulate boolean function representations through handwritten symbol and gesture recognition coupled with a drag-and-drop interface. We discuss LogicPad’s user interface and the general algorithm used

This paper proposes a new field of user interfaces called multi-computer direct manipulation and presents a pen-based direct manipulation technique that can be used for data transfer between different computers as well as within the same computer. The proposed Pick-and-Drop allows a user to pick up

In such settings, systems will be regularly employed by a few users (children or students

In this paper, we introduce the Intuidoc-Loustic Ges-tures DataBase (ILGDB), a new publicly available database of realistic pen-based gestures for evaluation of recognition systems in pen-enabled interfaces. IL-GDB was collected in a real world context and in an immersive environment
