What is VR? http://www.wiihaveaproblem.com/show_article.php?id=161

Virtual Reality Definition What is virtual reality? Virtual – being in essence or effect, but not in fact Example VRAM Reality – the state or quality of being real. Something that exists independently of ideas concerning it. Something that constitutes a real or actual thing as distinguished from something that is merely apparent.” What was the first VR?

What was the first VR?

Progression Story telling Multi-sensory Control What did this rely on? User’s imagination! Multi-sensory Images Sounds Control Events View What do these things have in common? Immersion

Define VR Burdea: Virtual reality is a high-end user-computer interface that involves real-time simulation and interactions through multiple sensorial channels. These sensorial modalities are visual, auditory, tactile, smell, and taste.

Burdea’s 3 I’s of VR Interactivity – user impacts world Define Channels Immersion – believing you are there What contributes to it? Imagination – user ‘buying’ into the experience Examples Why is this necessary?

Ivan Sutherland’s The Ultimate Display “Don’t think of that thing as a screen, think of it as a window, a window through which one looks into a virtual world. The challenge to computer graphics is to make that virtual world look real, sound real, move and respond to interaction in real time, and even feel real.”

Virtual Reality Ideal for VR is that everything you experience is computer-generated.

Best VR? Why?f

Not everything is real
