When considering the main VR platform, the main ideas were to use either the HTC VIVE or the CAVE2 at UIC. The reasons for this is that the camera controller provided by UIC is interactable with the CAVE2 specifically, while it also can be used with the HTC VIVE without any modification. This is important because these were the two main tools available at hand for testing. Other headsets were not considered because there was not ample opportunity to be able to test on them. AR was not considered for this project due to lack of knowledge in that area.
Ultimately, the HTC VIVE was chosen over the CAVE2. The reason for this is because the project is based on navigation through the virtual world through sound. While the CAVE2 is immersive and full, it does not allow for navigation and locomotion by walking. Rather, you can walk around and see surroundings, but your main locomotion is through the wand. The HTC VIVE on the other hand, like other headsets, has trackers that watch where you move in the physical space. It gives a sense of actually walking through the proposed levels.
Another advantage of a headset over the CAVE2 is that the surrounding 3-D sound can be better heard through a headset. For instance, when shooting a sound wave, it is easier distinguish the distance as the sound wave continues to move, and where the explosion finally lands. The goal zone is also easier to find since you can tell from the left and right ear signals.
The project was tailored for the VIVE by making sure all objects necessary were in the view of a headset. The projectile shooter is placed directly in front of the view, and all sound is set to 3-D to ensure that it can be heard in a certain direction. This should be universal for all headsets, provided that the necessary changes for buttons and camera controller are set for each different headset.
To make it more adaptable to the CAVE2, the two biggest changes needed would be size of space and how the body is tracked. There are certainly still cameras that watch the main goggles in the CAVE2, so it is possible to track and use the goggles to follow the body in the space. The next problem is then size of space. Because CAVE2 is more rotund than the rectangular space provided, the levels would need to be reshaped and smaller to adhere to the spatial limitations. The one big advantage this could provide is that because the CAVE2 is specific in size, there would be no possible discrepancy between what is given in virtual reality vs. what is given in real life.
