We present a mobile human view estimation system using a corneal imaging technique. Compared to the current eye gaze tracking (EGT) systems, our system does not require per-session calibrations and a frontal view (scene) camera, making it suitable for wearable glass systems because it is easier to use and more socially acceptable due to the lack of a frontal scene camera. Our glasses system consists of a glass frame and a micro eye camera that captures the eye (corneal) reflections of a user. 3D corneal pose tracking is performed for the captured images by using a particle filter-based real-time tracking method leveraged by a 3D eye model and weak perspective projection. We then compute the gaze reflection point (GRP) where the light from the point of gaze (PoG) is reflected, enabling us to identify where a user is looking in a scene image reflected on the corneal surface. We conducted experiments using a standard computer display setup and several real-world scenes, and found that the proposed method performs with considerable accuracy under non-calibrated setups. This demonstrates its potential for various purposes such as the user interface of a glasses systems and the analysis of human perceptions in actual scenes for marketing, environmental design, and quality-of-life applications.

Language：English Publisher：TUT Press

This book covers an approach to conversational informatics which encompasses science and technology for understanding and augmenting conversation in the network age. A major challenge in engineering is to develop a technology for conveying not just messages but also underlying wisdom. Relevant theories and practices in cognitive linguistics and communication science, as well as techniques developed in computational linguistics and artificial intelligence, are discussed.
