   "title": "Handheld Augmented Reality Interaction: Spatial Relations",
   "abstract": "We explored interaction within the context of handheld Augmented Reality (AR), where a handheld\r\ndevice is used as a physical magic lens to ’augment’ the physical surrounding. We focused, in\r\nparticular, on the role of spatial relations between the on-screen content and the physical surrounding.\r\nOn the one hand, spatial relations define opportunities for mixing environments, such as the\r\nadaptation of the digital augmentation to the user’s location. On the other hand, spatial relations\r\ninvolve specific constraints for interaction such as the impact of hand tremor on on-screen camera\r\nimage stability. The question is then, how can we relax spatial constraints while maintaining the\r\nfeeling of digital-physical collocation. Our contribution is three-fold.\r\n• First, we propose a design space for handheld AR on-screen content with a particular focus\r\non the spatial relations between the different identified frames of reference. This design space\r\ndefines a framework for systematically studying interaction with handheld AR applications.\r\n• Second, we propose and evaluate different handheld AR pointing techniques to improve pointing\r\nprecision. Indeed, with handheld AR set-up, both touch-screen input and the spatial\r\nrelations between the on-screen content and the physical surrounding impair the precision of\r\npointing.\r\n• Third, as part of a collaborative research project involving AIST-Tsukuba and Schneider-\r\nFrance and Japan, we developed a toolkit supporting the development of handheld AR applications.\r\nThe toolkit has been used to develop several demonstrators.",
