Towards Rapid Prototyping with Shape-Changing Displays for Designers
ShapeClip is a modular tool capable of transforming any computer screen into a z-actuating shape-changing display. This enables designers to produce dynamic physical forms by simply ‘clipping’ actuators onto screens.
ShapeClip displays are portable, scalable, fault-tolerant, and support runtime actuator re-arrangement. Users are not required to have knowledge of electronics or programming, and can develop motion designs with presentation software, image editors, and for those who require more control, web-standard interfaces.
There are 4 main software packages included here:
- Clip Firmware + Servo Extensions
- Websocket/Serial Bridge
- SUR40 Clip Detector (OpenCV)
- Web-based Sample Apps
In terms of software that can be used to create motion designs, ShapeClip is not restricted to any particular software package. You are free to work with the tools you know.
To get started you will need to get your hands on some ShapeClip hardware.To do that, you can view our design documents in the 01_Hardware folder.
Each standard Clip weighs ≈30g, and is 20×20×80mm when closed, and costs ≈USD$15. The selected stepper motor has 60mm of travel. Under stress, individual Clips draw between 60–540mA at 5V, enabling small groups to be powered via USB. When powering larger numbers, be sure not to make the chain of clips too long as you may damage the Clips. Clips are connected together with pin connectors that double up as a power transmission method. When the Clip is held upright, the top two pins of the power connector are +5v and the bottom one is GND. The motor and circuit logic are kept separate in the top two pins, but in most scenarios they can share power.
This work was conducted as part of the GHOST project (http://ghostfet-prod.cs.bris.ac.uk/) to further the understanding of shape-changing computer interfaces.
