Stumpfel, Jessi, Arvo, James and Novins, Kevin (2006): Geometric anticipation: assisting users in 2D layout tasks. In: Proceedings of the 2006 International Conference on Intelligent User Interfaces 2006. pp. 345-347. Available online
We describe an experimental interface that anticipates a user's intentions and accommodates predicted changes in advance. Our canonical example is an interactive version of "magnetic poetry" in which rectangular blocks containing single words can be juxtaposed to form arbitrary sentences or "poetry." The user can rearrange the blocks at will, forming and dissociating word sequences. A crucial attribute of the blocks in our system is that they anticipate insertions and gracefully rearrange themselves in time to make space for a new word or phrase. The challenges in creating such an interface are three fold: 1) the user's intentions must be inferred from noisy input, 2) arrangements must be altered smoothly and intuitively in response to anticipated changes, and 3) new and changing goals must be handled gracefully at any time, even in mid animation. We describe a general approach for handling the dynamic creation and deletion of organizational goals. Fluid motion is achieved by continually applying and correcting goal-directed forces to the objects. Future applications of this idea include the manipulation of text and graphical elements within documents and the manipulation of symbolic information such as equations.

Smithies, Steve, Novins, Kevin and Arvo, James (2001): Equation entry and editing via handwriting and gesture recognition. In Behaviour and Information Technology, 20 (1) pp. 53-67.
We describe a system for freehand entry and editing of mathematical expressions using a pen and tablet. The expressions are entered in the same way that they would be written on paper. The system interprets the results and generates output in a form suitable for use in other applications, such as word processors or symbolic manipulators. Interpretation includes character segmentation, character recognition, and formula parsing. Our interface incorporates easy to use tools for correcting interpretation errors at any stage. The user can also edit the handwritten representation and ask the system to reinterpret the results. By recovering the formula's structure directly from its handwritten form, the user is free to use common conventions of mathematical notation without regard to internal representation. We report the results of a small user study, which indicate that the new style of interaction is effective.
