Query: 4D Attention: Comprehensive Framework for Spatio-Temporal Gaze Mapping   This study presents a framework for capturing human attention in the
spatio-temporal domain using eye-tracking glasses. Attention mapping is a key
technology for human perceptual activity analysis or Human-Robot Interaction
(HRI) to support human visual cognition; however, measuring human attention in
dynamic environments is challenging owing to the difficulty in localizing the
subject and dealing with moving objects. To address this, we present a
comprehensive framework, 4D Attention, for unified gaze mapping onto static and
dynamic objects. Specifically, we estimate the glasses pose by leveraging a
loose coupling of direct visual localization and Inertial Measurement Unit
(IMU) values. Further, by installing reconstruction components into our
framework, dynamic objects not captured in the 3D environment map are
instantiated based on the input images. Finally, a scene rendering component
synthesizes a first-person view with identification (ID) textures and performs
direct 2D-3D gaze association. Quantitative evaluations showed the
effectiveness of our framework. Additionally, we demonstrated the applications
of 4D Attention through experiments in real situations.
