3D Heatmap Visualization of Gaze Distribution Measured from Observers Predicting Dynamism of Subject's Movement

Year: 2024
Type: article
Abstract: We propose a method to visualize the gaze distribution measured from an observer who perceives dynamism from the subject's movement in a movie using a three-dimensional (3D) heat map in a manner that is independent of time series changes in the subject's posture. In the previous method, the gaze distribution measured from an observer is represented using a heat map on a 3D human body model estimated from the subject in a still image. However, the previous method cannot handle time-series changes in the subject's posture in a movie. Furthermore, the previous method cannot visualize the gaze distribution measured from the surrounding region of the subject's body because it only considers the gaze distribution measured on the surface region of the subject's body. Our method introduces an angle between the gaze direction vector and the vertex position vector to visualize the gaze distribution measured in the surface and surrounding regions. From the experimental results, we confirmed that our method can visualize not only the gaze distribution measured in the surface region but also that measured in the surrounding region compared to the previous method. We also confirmed that it is possible to visualize the gaze distribution of a subject's movements in a movie without depending on time series changes using a standard posture human body model.
