Homework Assignment 1: Trapped By a Big Wall
For this assignment you can obtain 100 points, plus up to 10 points of extra credit.
In the description below we assume you will be using Unity 3D for the implementation. But you don't need to, you can alternatively use UE4, Lumberyard, or C++ with OpenGL and optionally OpenSceneGraph and the Bullet Physics Library
Note that if you use Unity you aren't allowed to use any Unity assets other than 3D models and textures without explicit permission.
The goal of this assignment is to create a VR application that is only used with the Oculus HMD (no controllers), and in which the user has to break out of a cylindrical brick wall.
The assignment is to be done in teams of two.
The Project (100 Points)
Create an interactive, immersive application for the Oculus Rift head mounted display (HMD). In the application, you are trapped inside of a seemingly impenetrable, tall, beautiful cylindrical brick wall - except that there wasn't enough money to put mortar between the bricks so they just sit loosely on top of one another. Luckily, you have telekinesis superpowers that you can use just by using your gaze. When you focus on a brick (by staring at it), the brick starts moving away from you slowly, and will eventually fall out of the other side of the wall. The goal is to destroy enough of the wall so that you could climb over it.
In this application you are only allowed to use the HMD as an input device (i.e., no mouse, keyboard, Touch controllers, or other input devices are allowed). You are not allowed to move the user, except the user's head with their natural head motion. The brick wall should be far enough away from the user so that the user can't stick their head through it (at least 4-6 feet).
You will get points for the following things:
- A ground plane nothing can fall through. (5 points)
- A cylindrical wall of bricks, generated procedurally from code. It should consist of simple rectangular boxes. The bricks need to be textured or colored with a texture/color of your choice. In Unity, you should create a brick prefab and instantiate the wall using instances of that prefab. The bricks must have realistic physics properties applied to them. Assume that 1 cubic foot of rock weighs about 200 lbs. (30 points)
- Telekinesis: when the user stares at a brick for a minimum threshold amount of time (eg, 2 seconds), telekinesis kicks in. The brick the user stares at slowly starts moving towards the outside of the wall. It should take between 5-10 seconds for the brick to move all the way out until it falls down. The physics simulation should realistically make the bricks above the removed one tumble down. (30 points)
- There needs to be a visual indication of where the user looks (eg, cursor). (10 points)
- There needs to be a visual indication of which brick is being pushed while the telekinesis is active (highlighting, displaying sparks on its front, etc). (10 points)
- If the user looks away from the brick they're doing the telekinesis on, the brick should stop moving. (5 points)
- You should be able to reset the wall by looking straight up to the sky, within a small threshold around the zenith. (10 points)
Let these images inspire you:
Left: brick wall from the outside, right: brick wall from user's perspective.
Extra Credit (10 Points)
There are two options for extra credit. To get the full 10 points you have to implement both of them, in the given order.
1. Telekinesis trigger indicator: all gaze interactions would benefit from a visual indicator of how long the user has stared at a point and how much longer they need to do it to trigger the action. Any visual progress indicator located by the object that is looked at will be accepted (such as progress bars, pie charts, shapes that fill up with water), but not textual ones (such as a count down). (5 points)
Examples:
Radial widget: 
Slider widget: 
Hexagons: Hexagons
2. Teleport with gaze: This option requires that you already did option 1. Add a method to teleport around the scene by gazing at the ground plane. If there is an intersection of the gaze ray with the ground plane, without an obstruction in between, mark the intersection point, start the gaze progress indicator, and once the time is up move the user's feet to that location. (5 points)
