Project 04 |
Goals
- Design and implement an accelerometer/compass controller for a Unity Application.
- Control the x, y, z position and rotation.
- Navigate a space in Unity using the controller.
|
Create Unity World |
Install Unity
On your personal laptop install Unity.
Create a new 3D unity project scene
- Create a plane
- Game Object Menu -> 3D Object -> Plane
- In the object inspector tab set the scale in the x and z direction to 100.
- Create a sphere
- Game Object Menu -> 3D Object -> Sphere
- In the object inspector tab set the sphere scale in the x, y and z direction to 10.
- In the object inspector tab set the sphere position to (0,7,50).
Create a new C# script
- Create a new script
- Unity Manual: Creating and Using Scripts
- In the project tab click on the Assets folder
- Assets Menu -> Create -> C# Script
- Name your new script "cameraBehavior"
- Double click on your "cameraBehavior" script
- Before the start method create a public float field named rotationDegree and set it equal to 0.1f.
- Attach cameraBehavior script to Main Camera
- Click on Main Camera in Hierarchy tab
- Click on Add Component -> Scripts -> Camera Behavior
- A new Camera Behavior Component should appear in the inspector tab with the ability to set the rotationDegree field.
- Rotate Camera left and right using left and right arrow keys
Update script
- Add rotation around x, y and z axis
- Rotate "rotationDegree" around the x axis up when the up arrow is pressed and down when the down arrow is pressed.
- Rotate "rotationDegree" around the z axis clockwise when the key "z" is pressed and counter clockwise when the key "q" is pressed.
- Save your script.
- Click the play button and use the keys to test your program.
- Add movement up, down, left, right, forward and back
- Before the start method create a public float field named speed and set it equal to 5.0f.
- Update the object's position forward when pressing 'w', backward when pressing 'x', up when pressing 'e', down when pressing 'c', left when pressing 'a', and right when pressing 'd'.
- Make sure to convert your vector from local space to world space using TransformDirection
- Save your script.
- Click the play button and use the keys to test your program.

Gesture Controller |
Setup
Start with your code from Lab 4.
Save it as a new Arduino project titled colbyUsername_P04 (with your colby username, mine would be hewolfe_P04).
Gesture Controller Design
Design an accelerometer based interface to navigate a 3D space.
Interface requirements:
- Control X, Y and Z position of camera in object space
- Control roll, pitch and yaw rotation of camera
- Turn controller "on" and "off"
You may choose to filter or smooth your data using methods from the previous projects.
Carry-over from Lab
Loop Function
- Use Linear Interpolation to smoothly transition from your accelerometer readings to camera movement.
- Convert values from movement to key presses.
Linear Interpolation
Write a method that will take a value from one range and map it to a new value inside another range. The idea here is that we want to map the input value, x, which is within the range x0 to x1, to a new range y0 to y1.
y the new value (output)y0 the new minimum value y1 the new maximum value x the input value x0 the original minimum value x1 the original maximum value
Documentation and Analysis
- User Interface Documentation
- Using a diagram, explain how your interface works.
- In a short paragraph explain how your interface works and why you made the design decisions that you did.
- Analysis
- How easy is it to use the interface?
- How accurate is it?
- Were there any modifications you made to it increase the accuracy/usability?

Extension |
Minor Extensions
Minor extensions build on the pre-existing circuit for this project.
Here are a few examples:
- Add additional functionality/controls.
- Create a more complex scene and control aspects of it with the accelerometer.
- Implement, test and compare other types of interpolation (SLERP etc).
- Connect to a device that is not a phone or computer and create an interface for it. Include atleast 3 commands and explain your user interface design.
Document your minor extension:
- Submit your code on filer in a folder inside your project folder.
- A 1-3 minute video documenting your extension working. (If different from project)
- A description of the extension.
- A section on implementation.
- A section on results & reflection.
- Include any relevant charts or graphs.
Major Extension
Design and implement an idea for a new project which involves adding new components and modifying the circuitry.
- It must incorporate the materials from this project; the bluetooth and accelerometer breakout boards.
- It must include atleast one of the following components: microphone, a piezo element, the IR emitters, IR receivers, and/or the vibrating motors.
- It can include potentiometers, buttons and/or red LEDs.
Document your major extension:
- Submit your code on filer in a folder inside your project folder.
- A 1-3 minute video of the system working.
- A description of the extension.
- A circuit diagram.
- A photograph of the circuit board.
- A section on implementation.
- A section on results & reflection.
