Sketched Reality: Sketching Bi-Directional Interactions Between Virtual and Physical Worlds with AR and Actuated Tangible UI
This paper introduces Sketched Reality, an approach that combines AR
sketching and actuated tangible user interfaces (TUI) for bidirectional
sketching interaction. Bi-directional sketching enables virtual sketches and
physical objects to "affect" each other through physical actuation and digital
computation. In the existing AR sketching, the relationship between virtual and
physical worlds is only one-directional -- while physical interaction can
affect virtual sketches, virtual sketches have no return effect on the physical
objects or environment. In contrast, bi-directional sketching interaction
allows the seamless coupling between sketches and actuated TUIs. In this paper,
we employ tabletop-size small robots (Sony Toio) and an iPad-based AR sketching
tool to demonstrate the concept. In our system, virtual sketches drawn and
simulated on an iPad (e.g., lines, walls, pendulums, and springs) can move,
actuate, collide, and constrain physical Toio robots, as if virtual sketches
and the physical objects exist in the same space through seamless coupling
between AR and robot motion. This paper contributes a set of novel interactions
and a design space of bi-directional AR sketching. We demonstrate a series of
potential applications, such as tangible physics education, explorable
mechanism, tangible gaming for children, and in-situ robot programming via
sketching.Comment: UIST 202
