Study of three-dimensional (3D) gaze and depth perception in immersive virtual environment (IVE) systems is an important research area. Several approaches have been proposed, but the usage of gaze-screen information for depth perception measurement in IVE has never been reported. We suggest a new approach using geometric model to measure depth perception in IVE. We extend information from binocular gaze-screen mapping and obtain the depth information by line-crossing method. We also investigate error of depth perception by eye camera alignment and front/behind screen condition. Our simulation results show that the 2D gaze tracking estimation error of the proposed method is lower than 1° and yields depth measurement accuracy more than 84% on ±0.6 to ±1 meter depth of front/behind screen condition.
