SPATA: Spatio-Tangible Tools for Fabrication-Aware Design.

ABSTRACTThe physical tools used when designing new objects for digital fabrication are mature, yet disconnected from their virtual accompaniments. SPATA is the digital adaptation of two spatial measurement tools, that explores their closer integration into virtual design environments. We adapt two of the traditional measurement tools: calipers and protractors. Both tools can measure, transfer, and present size and angle. Their close integration into different design environments makes tasks more fluid and convenient. We describe the tools' design, a prototype implementation, integration into different environments, and application scenarios validating the concept.
