ABSTRACT
This chapter addresses the exciting question through a fresh discussion of the science, techniques, and applications of sketching in 3D space. It ocuses specifically on a different form of sketching that may be new to many readers. Sketching is expressive while also being immediate and easily editable. Sketching enables rapid exploration. Sketching in 3D space promises to overcome these limitations by combining the best of both worlds. In theory, this leads to a medium that provides designers with both the expressiveness, immediacy, and edit-ability of traditional 2D sketching as well as the body-centered spatial awareness, presence, and multiple perspectives afforded by traditional 3D design tools, such as prototyping. In recent years, AR and AR technologies have become more widely available through commercial outlets and consequently, there is wider availability of tools that allow for sketching in 3D space.
