PhoneCanvas: 3D Sketching System Using a Depth Camera-Equipped Smartphone as a Canvas

We present PhoneCanvas, a system using a depth camera-equipped smartphone as a canvas, which enables users to draw 3D sketches and view their sketches on a PC in real-time. Users can draw lines, erase lines, and draw surfaces by varying their hand gestures and rotating 3D models by rotating their smartphones. This system allows for 3D sketching operations using hand gestures, with the aim of providing operations for 3D modeling beginners to perform rapid prototyping. PhoneCanvas addresses the issue of a few 3D sketching systems for beginners balancing both installation costs and operability. We conducted studies with 3D modeling beginners to test the performance of the system. The study results showed that the system can be used for rapidly prototyping various 3D models and discussions.
