VR Fails
Scenario 1
One common scenario involves users inadvertently throwing themselves into their TVs while using VR headsets, as they frequently opt to use these devices in their living rooms.
In such situations, implementing a boundary system is essential. This system alerts users with visual and haptic signals when they near the predefined safe aera in their VR environment.
Nonetheless, there are instances where users, deeply engrossed in the virtual world, engage in vigorous activities such as running and jumping. The omnidirectional treadmills can provide a controlled environment for their VR experiences.
Scenario 2
When using VR headsets, the user’s vision of the real world is completely obscured, which can lead to accidental injuries if other people or pets enter their play area.

Here is an example of Apple Vision Pro.
CAVE System
What is CAVE?
A CAVE(Cave Automatic Virtual Environment ) is an immersive virtual reality environment where projectors are directed to between three and six of the walls of a room-sized cube. The user wears 3D glasses inside the CAVE to see 3D graphics generated by the CAVE.
CAVE System vs Head-Mounted Display
CAVE is a room-scale system where images are projected onto the wall. It allow multiple users to be in the same physical space and see the same virtual environment. For HMD, it consists of a stereo pair of small displays that cover the eyes. It is worn on the head and providing an individual VR experience.
- CAVE
- Advantages
- A nonintrusive easy-to-learn high-resolution virtual reality interface. It’s good for collaborative work.
- Disadvantages
- Very expensive, not easy to set up, requires a dedicated space.
- Advantages
- HMD
- Advantages
- More affordable and easy to use.
- Disadvantages
- Highly intrusive because it completely isolates the viewer from the real world.

When more people experience the cave system at the same time, especially when they collaborate, it increases the reality. So in this case, the position should move a bit to the left.
