constructable & LaserOrigami: interactive lasercutting of two- and threedimensional mechanical objects
Stefanie Mueller, Human Computer Interaction Lab, Hasso Plattner Institut
The traditional workflow in personal fabrication is that users sit at the computer, create a digital model in a 3D editor, and after all editing is done fabricate the physical object. While there are good reasons for doing this, such as editing with high accuracy and the availability of undo, it also removes the user from the physicality of the workpiece.
In this talk, we propose to change this workflow by (1) allowing users to work directly on the workpiece again as known from traditional crafting, and (2) by providing physical output of the fabrication device after every editing step.
We developed two projects that follow this paradigm: The first project is constructable, which is an interactive drafting table based on a laser-cutter that allows users to directly draw on the workpiece using handheld laser-pointers. An overhead camera tracks the laser-pointer, beautifies the path and finally cuts the workpiece. The second project is LaserOrigami, which is a method to interactively create 3D objects using a laser-cutter without any manual assembly. LaserOrigami achieves this by cutting and bending the workpiece in a single integrated process by switching between a focused and defocused laser.
Stefanie Mueller is a PhD student in the Human-Computer Interaction Group at Hasso Plattner Institute where she works with Prof. Patrick Baudisch on new interfaces for personal fabrication. Her research paper "LaserOrigami: Laser-cutting 3D objects" won a best paper award at the ACM SIGCHI Conference on Human Factors in Computing Systems 2013, the premier conference in the field of Human Computer Interaction. Stefanie was also an invited speaker at the rapid prototyping panel of the TSB Technologiestiftung Berlin in April this year.
