Handheld Augmented Reality: Spatial Relationships and Frames of Reference

In Workshop on Designing Mobile Augmented Reality at MobileHCI 2013. 2013.

Thomas Vincent, Laurence Nigay, Takeshi Kurata


Handheld Augmented Reality (AR), one type of mobile AR, relies on the spatial coupling between the real world and the on-screen augmented reality outputs. Such spatial coupling introduces new design challenges for interaction and in particular for precise pointing techniques that go beyond mobile interaction design challenges (e.g., screen real estate, fat-finger problem with direct touch on the screen). Focusing on the design of touch interaction techniques for handheld AR, we propose two conceptual design elements, namely spatial relationship and frame of reference, as part of a conceptual framework organized according to four main entities: (1) the control space, (2) the digital augmentation (3) the representation of the physical world and (4) the physical world.
