Lesson Focus

With the mass production and availability of low cost and robust head-mounted displays (HMDs), there has been increasing interest in virtual reality technologies – for example the Oculus Rift, HTC Vive, Samsung VR Gear, Microsoft HoloLens, and Sony’s PlayStation VR. These display technologies are based around artificial stereo images, and provide a view with illusions of 3D depth in virtual environments. Students will use the scientific method to study ‘anaglyph’ (movie 3D) technologies to model computer science design and learn how stereo images create the illusion of 3D.
