1 Design Issues in Gaze Guidance Under review with ACM Transactions on Computer Human Interaction

The idea of gaze guidance is to lead a viewer’s gaze through a visual display in order to facilitate his/her search for specific information. This study elaborates on the process of guiding gaze from one spatial position to another, whereby the goal is to create a guidance process that is as least-obtrusive as possible. A list of guidance aspects is discussed and then applied to two specific scenarios, car cockpit and PC monitor. To explore some of those aspects, an experimental framework is introduced in which subjects perform a difficult letter search and identification task in dynamic noise. To facilitate this recognition task, the viewer is guided by a luminance ‘marker’. It is investigated how the marker’s spatio-temporal properties influence the recognition performance. From those results we derive a number of design recommendations for the process of gaze guidance. Content indicators
