3D attention: measurement of visual saliency using eye tracking glasses

Understanding and estimating human attention in different interactive scenarios is an important part of human computer interaction. With the advent of wearable eye-tracking glasses and Google glasses, monitoring of human visual attention will soon become ubiquitous. The presented work describes the precise estimation of human gaze fixations with respect to its environment, without the need of artificial landmarks in the field of view, and being capable of providing attention mapping onto 3D information. It enables full 3D recovery of the human view frustum and the gaze pointer in a previously acquired 3D model of the environment in real time. The key contribution is that our methodology enables mapping of fixations directly into an automatically computed 3d model. This innovative methodology will open new opportunities for human attention studies during interaction with its environment, bringing new potential into automated processing for human factors technologies.
