GazeSync: A Mobile Eye-Tracking Tool for Analyzing Visual Attention on Dynamically Manipulated Content
Yaxiong Lei, Rishab Talwar, Shijing He +5
Conventional mobile eye-tracking maps gaze to static screen coordinates, failing to capture user attention when content is dynamic. As users pinch, zoom, and rotate images, static…
GazeCode: Recall-Based Verification for Higher-Quality In-the-Wild Mobile Gaze Data Collection
Yaxiong Lei, Thomas Davies, Xinya Gong +2
Large-scale mobile gaze estimation relies on in-the-wild datasets, yet unsupervised collection makes it difficult to verify whether participants truly foveate logged targets. Prior…
TinyGaze: Lightweight Gaze-Gesture Recognition on Commodity Mobile Devices
Yaxiong Lei, Hyochan Cho, Fergus Buchanan +4
Gaze gestures can provide hands free input on mobile devices, but practical use requires (i) gestures users can learn and recall and (ii) recognition models that are efficient enou…
The People's Gaze: Co-Designing and Refining Gaze Gestures with General Users and Gaze Interaction Experts
Yaxiong Lei, Xinya Gong, Shijing He +3
As eye-tracking becomes increasingly common in modern mobile devices, the potential for hands-free, gaze-based interaction grows, but current gesture sets are largely expert-design…
MAC-Gaze: Motion-Aware Continual Calibration for Mobile Gaze Tracking
Yaxiong Lei, Mingyue Zhao, Yuheng Wang +4
Mobile gaze tracking faces a fundamental challenge: maintaining accuracy as users naturally change their postures and device orientations. Traditional calibration approaches, like…
Quantifying the Impact of Motion on 2D Gaze Estimation in Real-World Mobile Interactions
Yaxiong Lei, Yuheng Wang, Fergus Buchanan +5
Mobile gaze tracking involves inferring a user's gaze point or direction on a mobile device's screen from facial images captured by the device's front camera. While this technology…
