Saccaidance: Saccade-Aware Pattern Embedding for Gaze Guidance on High-Speed Displays

Gaze guidance is essential for directing user attention to specific areas of interest. However, conventional visual cues generate persistent visual noise that hinders concentration during tasks. We propose Saccaidance, a gaze-guidance method that appears only when users move their gaze. Saccaidance employs temporal additive color mixing and 480 Hz high-speed displays to shift the color phase of guidance patterns. This renders the patterns barely visible during fixation and makes them appear transiently when users move their gaze as a color-breaking effect. This intermittent gaze guidance appears only during gaze transitions, providing effective guidance without interfering with focused work or requiring eye-tracking hardware. We conducted experiments with 24 participants under four conditions that involved search tasks: an unmodified baseline, conventional explicit guidance, and our proposed method using oval and radial patterns. The results show that our approach effectively constrains the exploration area while preserving subjective naturalness. We also outline application scenarios of our method, including document highlighting.
