Scrolling is an essential part of our everyday computing experience. Contemporary scrolling techniques rely on the explicit initiation of scrolling by the user. The act of scrolling is tightly coupled with the user?s ability to absorb information via the visual channel. The use of eye gaze information is therefore a natural choice for enhancing scrolling techniques. We present several gaze-enhanced scrolling techniques for manual and automatic scrolling which use gaze information as a primary input or as an augmented input. We also introduce the use off-screen gaze-actuated buttons for document navigation and control.

Students, scientists and engineers have to choose between the flexible, free-form input of pencil and paper and the computational power of Computer Algebra Systems (CAS) when solving mathematical problems. Hands-On Math is a multi-touch and pen-based system which attempts to unify these approaches by providing virtual paper that is enhanced to recognize mathematical notations as a means of providing in situ access to CAS functionality. Pages can be created and organized on a large pannable desktop, and mathematical expressions can be computed, graphed and manipulated using a set of uni- and bi-manual interactions which facilitate rapid exploration by eliminating tedious and error prone transcription tasks. Analysis of a qualitative pilot evaluation indicates the potential of our approach and highlights usability issues with the novel techniques used.
