Project Proposal

1. Project Title
1. Hand Gestured 3D Pin Art
2. Team
1. Carter Rice
2. Satya Bodduluri
3. Motivation:
1. Many forms of art today attempt to visualize the world that exists around us. Lighting systems exists that synchronize their colors to the music that is playing, while some displays mimic the motion of the user. The main concept behind 3D Pin Art is to take those two aspects as well as many other aspects of art and create a system that can demonstrate them. In a grid of pins that can be raised up and down, different musical patterns can be created, varying contours can be demonstrated, and even hand gestures can be implemented to take control of the surface. With 3D Pin Art, the user no longer has to make the final call between interaction and observation, but can experience both.
4. Goal
1. Create a flat gridded surface where each cell of the grid can be actuated upwards based on 2 kinds of inputs (2 modes)
1. Audio
2. Hand gestures
5. Methodology
1. Gridded Surface
1. Use many mini servos with cams that will push rods connected to the tiles to actuate them upward

2. Audio Input
1. Break up audio of into different frequencies and actuate different sections of the board for different parts of the spectrum
3. Hand Recognition
1. Use a camera to detect position of hand and raise the section of the board that is underneath it
2. Project Components
1. Hardware
1. Wiring for motors (H-bridges if needed)
2. Relay system to switch between different positions on display
3. PWM Chip to control the many servos (since servos need a constant PWM input to hold their position)
4. Build an audio filter circuit to analyze different aspects of the audio signal
2. Software
1. Microcontroller
1. Controlling the motors
2. Interpret audio input
2. Camera
1. Detect hand position
3. Mechanical
1. Utilize cams to actuate the grid cells
2. Create a rig that can hold all of our various components
3. Deliverables
1. Baseline:
1. A fully working 3D Pin board
2. Board will track hand and raise sections that are underneath it
3. Add RGB Leds to the top of each pin that light up as the pin actuates
2. Reach
1. Use more advanced hand gestures to implement a holding pattern on display. Then sections of display can be raised up or down based on hand orientation
4. Timeline

Week One: Create controllable pin using cam and micro servo, create control functions

Week Two: Compile version of pin array, begin design of audio filter and hand detection

Week Three: Integrate the mechanical and electronic parts together, i.e. finish baseline

Week Four: Implement reach goal
