Cognitive activities in recognition directional judgment, such as short-term memory, were examined on a virtual tilted screen by using stereoscopic three-dimensional (3D) images. The virtual tilted screen was composed of 3D images; 2D images without perspective views were converted into tilted 3D images by using a simple gradient depth map. In the experiments, a cognitive bias in directional judgment was induced as participants were allowed to perceive the tilted direction through binocular disparity with positive parallax. In Experiment 1, a subjective evaluation in which tilted simple stimuli were presented on a 3D screen was performed, and participants were able to make a right or left turn on a driving simulator. The participants made a directional judgment at the intersection after viewing tilted 3D images. Experiment 2 was carried out to evaluate the rate of correct answers and searching times in four conditions: with 2D, 3D, or tilted 3D images, and tilted 3D distractors. In the tilted 3D condition, tilted 3D images were presented in the same direction as instructed via headphones (“Left” or “Right”). Images were presented in the opposite direction from that indicated via headphones in the tilted 3D distractor condition. The results suggested that the tilted 3D condition was able to easily support participants’ directional judgment as well as remain in short-term memory.
