  • Sample Video of VR Task (16.2 MB) This sample clip shows a subject performing a search task in the VR world. The magenta circle indicates where on screen the subject was looking during the task.
  • Colorized Sample Video of VR Task (4.07 MB) This sample clip shows a subject performing a search task in the VR world. The objects of interest in the world, such as people or fruits, have been set to unique RGB color values. Different body parts of each person are coded separately. For example, the eyes, mouth, and hands of a person all have distinct RGB values. Software that can detect the RGB value associated with each object in every frame of the video allows us to code which objects the subject was viewing at every frame in the VR world. The colorization technology was developed by Psychology Software Tools, Inc.
