Augmented Reality And Virtual Reality
What Is Augmented Reality (AR)? A combination of a real scene viewed by a user and a virtual scene generated by a computer that augments the scene with additional information.
Nuts and Bolts of AR Characteristics of AR Hardware Needed It combines real and virtual It is interactive in real time It is registered in 3D Hardware Needed Display Input devices-camera Processer-CPU Sensors-accelerometer Tracking-GPS, compass
What is Virtual Reality (VR)? Virtual reality or virtual realities (VR), also known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user's physical presence that environment in a way that allows the user to interact with it.
A true VR experience should include: Nuts and Bolts of VR A true VR experience should include: Three-dimensional images that appear to be life-sized from the perspective of the user The ability to track a user's motions, particularly his head and eye movements, and correspondingly adjust the images on the user's display to reflect the change in perspective
Nuts and Bolts of VR Hardware Needed A device-phone either android or iOs Google cardboard, or another VR headset Google cardboard app
Augmented Reality vs. Virtual Reality System augments the real world scene User maintains a sense of presence in real world Needs a mechanism to combine virtual and real worlds Hard to register real and virtual Virtual Reality Totally immersive environment Senses are under control of system Need a mechanism to feed virtual world to user Hard to make VR world interesting Computer generated virtual objects must be accurately registers with the real in all dimensions. Errors in registration prevent the real and virtual images from being seen as fused. Registration must be maintained while the user moves around in the virtual environment. Changes in registration can be distracting or physically disturbing.
