Digital canvas: A projection-space interaction tool

Abstract

We introduce a projection-space interaction tool (Digital Canvas) which can be used for visual environments. Using Digital Canvas, users are allowed to interact with the visual items on the same space where they are displayed. Digital Canvas has resolved some limitations of previous interaction tools by merging interaction space and display space, providing tangible interface, and allowing for intuitive and natural interfaces. Digital Canvas was successfully used for digital painting education and a virtual environment manipulation. As a painting tool, it provided tactile feedback, freedom of choosing painting tools, erasable and undoable procedures, and an interface that is similar to traditional painting. As a virtual environment interaction tool, Digital Canvas allowed for projection-space tangible interactions using physical objects.
