Abstract:
Laser cutters are increasingly relevant within many user contextsand have
become an essential tool for model building and prototyping. While providing
precision and flexibility, these tools are typically suited for expert staff
in industrial settings. VAL (Visually Augmented Laser cutting) proposes a
novel system utilizing spatial augmented reality techniques to provide visual
augmentation directly on the work surface. VAL involves projection of the
user’s model prior to and during laser cutting providing key benefits
including minimizing idle time, reduction of errors, and support for new
creative practices. We interview and observe laser cutter users to identify
issues and concerns in the shared work context of a design school and
describe the design process for our prototype, which aims to address these
problems and unmet needs. Initial evaluation suggests VAL reduces complexity
and raises user confidence. Our findings extend research on adapting new use
contexts and creative practices with industrial fabrication tools.
