A gaze-directed lens for touchless analytics

Abhishek Chander; Advait Sarkar

We present the design and implementation of a gaze-directed lens tool for the interactive exploration of quantitative chart visualisations. In view of visual analytics as end-user programming, we present lenses which enable the selective display of labels, as well as interaction with parameterised uncertainty. We describe an algorithm for smoothing the movement of the lens. We report a controlled, within- subjects experiment on 11 participants demonstrating that participants were as adept at moving the lens with their gaze as they were using a mouse, and furthermore, that the gaze-directed interface promoted greater inspection of the key regions of the grapĀ
