CurveBall is an ergonomic input device that uses grip and motion to interact with modal UIs. Hardware for this project was developed by Scott Gilliland as part of a UROC Project.
Curveball with half of outer gel layer
- Off-the-desk interaction is important in ubiquitous computing
- Most off-the-desk input devices do not support complex tasks
- Apply multitouch interaction techniques to ergonomic surfaces for creating more expressive interactions
- Expand multitouch interaction by using pressure as another dimension of input
- Inner core holds 3-axis accelerometer and SimpliciTI platform for transmitting data. The core is powered with an iPod shuffle battery.
- Core is surrounded by 12 photo transistors and 20 leds
- Readings from the photo transistors vary with touching and amount of pressure applied to outer layer
- Outer layer of ballistics gel provides an easy to grip and ergonomic surface for use
- Pressure values and acceleration information are passed to a computer to perform recognition on motion and grip
