Hudson, Scott E. and Newell, Gary L. (1992): Probabilistic State Machines: Dialog Management for Inputs with Uncertainty. In: Mackinlay, Jock D. and Green, Mark (eds.) Proceedings of the 5th annual ACM symposium on User interface software and technology November 15 - 18, 1992, Monteray, California, United States. pp. 199-208.

Traditional models of input work on the assumption that inputs delivered to a system are fairly certain to have occurred as they are reported. However, a number of new input modalities, such as pen-based inputs, hand and body gesture inputs, and voice input, do not share this property. Inputs under these techniques are normally acquired by a process of recognition. As a result, each of these techniques makes mistakes and provides inputs which are approximate or uncertain. This paper considers some preliminary techniques for dialog management in the presence of this uncertainty. These techniques -- including a new input model and a set of extended state machine abstractions -- will explicitly model uncertainty and handle it as a normal and expected part of the input process.

Henry, Tyson R., Hudson, Scott E. and Newell, Gary L. (1990): Integrating Gesture and Snapping into a User Interface Toolkit. In: Hudson, Scott E. (ed.) Proceedings of the 3rd annual ACM SIGGRAPH symposium on User interface software and technology October 03 - 05, 1990, Snowbird, Utah, United States. pp. 112-122.

This paper describes Artkit -- the Arizona Retargetable Toolkit -- an extensible object-oriented user interface toolkit. Artkit provides an extensible input model which is designed to support a wider range of interaction techniques than conventional user interface toolkits. In particular the system supports the implementation of interaction objects using dragging, snapping (or gravity fields), and gesture (or handwriting) inputs. Because these techniques are supported directly by the toolkit it is also possible to create interactions that mix these techniques within a single interface or even a single interactor object.
