VR Application

Creating a short and easy vr experience was fun and extremely easy. With the Google street view app I was able to go to the URC and take a 360 degree photo so that others can experience the same setting. Once I decided on a place it was as simple as opening the app and taking pictures. Although, I did have trouble managing to get every angle accounted for. In my Streetview example I managed to take pictures around me but in certain angles I missed taking the photo so it resulted in not a full 360 degree photo. I managed to get very close and you can still immerse yourself in the pictures I took.

Degrees of Freedom are very relevant when talking about this Streetview experience because it is the idea of how you can interact with the application. In XR apps there are either 3 or 6 degrees of freedom that you utilize. This app is specific to 3 degrees of freedom because you are only able to stand still and move your head around. Each different movement is either a pitch, yaw or roll. A pitch rotation is when you rotate your head up and down to see something above or below you, yaw rotation is when you look side to side and rolling is when you tilt your head. Each of these are include in 3 DOF applications.

In 6 DOF applications we need to be able to move around besides just looking around so we need to be able to elevate, strafe and surge. Elevating is moving up and down, strafing is side to side and surging is forward and backwards. When you add all of these together you get 6 degrees of freedom which allow for full body movement and visual rotation inside of a VR application.

Knowing how these effect applications is also important. In an application that supports 6 DOF we would expect more interactivity and immersion. These are going to be the apps that require more involvement and can do more things thus giving you a better out-of-this-world experience. In 3 DOF applications it is possible to feel less immersed because of the fact that you are only allowed head movement.

With more degrees of freedom this 3D image could transform from being just a picture to an actual place to go. If I could move around, it would increase my immersion and I would be tricked into thinking I was actually there. The cutoff for having either 3 DOF or 6DOF is very large. When I sit inside the 3D photo in 3 DOF I am not fully immersed, but from experience in other 6 DOF apps I believe I would have a lot more fun and be able to view things as if I were really there.

One thing I learned while inside my app is how different the peripheral vision is. Since I was there in person and also there in VR it was interesting to see how the VR version really limits your vision to more straight ahead. I always knew that VR technology was limiting in this way but it amazed me at how much it really cut off. I think the next VR technology that eliminates this problem is going to make a lot of money!
