Spatial Sketch: Bridging Between Movement & Fabrication


Spatial Sketch is a three-dimensional (3D) sketch application that bridges between physical movement and the fabrication of objects in the real world via cut planar materials. This paper explores the rationale and details behind the development of the Spatial Sketch application, and presents our observations from user testing and a hands-on lamp shade design workshop. Finally we reflect upon the relevance of embodied forms of human computer interaction for use in digital fabrication.

Sketching with the Spatial Sketch application.

Slices can be projected from sketches in parallel (left) and radial (right) mode.

The 2D slices are then adjusted to house a small light bulb and fabricated using a laser cutter.

Presentations and workshops conducted during our research.
