1. Outline the similarities and differences between the following:
BOOM, CAVE, HMD

Definitions –
The BOOM (Binocular Omni-Orientation Monitor) is a head-coupled stereoscopic display device.
The CAVE (Cave Automatic Virtual Environment) provides the illusion of immersion by projecting stereo images on the walls and floor of a room-sized cube.
The head-mounted display (HMD) was the first device providing its wearer with an immerse experience.

The similarities between these three virtual reality mechanisms is that they all trick human brains into believing in a artificial environment which is basically what virtual reality is. They are all machines that enable humans to experience virtual reality.

2. Distinguish between immersive and non-immersive VR technologies. Provide examples.

Immersive VR is more realistic and tricks the mind more than non-immersive. Immersive VR is more when users put on a head set and can experience 3D environments, depth in the environment, a natural interface, and enhances the perception of depth in the virtual environment. Non-immersive VR is like a simulator on a screen such as the Google Earth Flight Simulator. It is not that immersive compared to immersive VR.

3. Explain whether VRML is immersive or non-immersive VR technology.

VRML is non-immersive VR technology. This is because VRML takes place on a screen where the user does not become immersed in it like real immersive VR. VRML provides three-dimensional worlds with integrated hyperlinks on the web. VRML plug-ins are usually in a mouse control, which means that VRML is not fully an immersive technology.

4. Outline areas of business that VR would be helpful. For each area describe how it might be applied.

* VR would be helpful for airplane pilots and helicopter pilots in training. VR would provide realistic training for these pilots and would be very helpful for training.

* High tech gaming will be very realistic and very fun if VR is used as an application. VR will provide a very fun gaming experience, such as 3 Dimensional Game.

* The army can use VR for training its soldiers through VR as VR would provide realistic environments where soldiers can train with what ever they want.

* VR can also help drivers in driving school. Instead of companies using real cars, they can save money, time and space by using VR. That way, people can put on headsets and experience very realistic driving in order to complete tests for their drivers license.

* VR will help on Visual Arts such as 3-D computer graphic art and also Picture Motion Industry such as computer graphics movie. In Movie Industry, VR will help people to make a Virtual Actrees.
