ARtalet: Tangible User Interface based Immersive Augmented Reality Authoring Tool for Digilog book
Abstract
A Digilog Book is an augmented reality (AR) based next generation publication supporting both sentimental analog emotions and immersive digital contents to improve a user’s experience. This paper enhances the Digilog Book authoring tool, ARtalet. This is a tangible user interface based immersive AR authoring tool providing an intuitive nonprogramming based authoring methods using a 3D user interface in an AR environment. As novel authoring functions, we propose 3D object trajectory manipulation, real-time deformation, and audio/vibration feedback authoring functions to enhance a user’s experience and interest. The ARtalet can be applicable to other Digilog application authoring, including posters, pictures, newspapers, and sign boards.

An Empirical Evaluation of Virtual Hand Techniques for 3D Object Manipulation in a Tangible Augmented Reality Environment
Abstract
In this paper, we present a Fitts’ law-based formal evaluation process and the corresponding results for 3D object manipulation techniques based on a virtual hand metaphor in a tangible augmented reality (TAR) environment. Specifically, we extend the design parameters of the 1D scale Fitts’ law to 3D scale and then refine an evaluation model in order to bring generality and ease of adaptation to various TAR applications. Next, we implement and compare standard TAR manipulation techniques using a cup, a paddle, a cube, and a proposed extended paddle prop. Most manipulation techniques were well-modeled in terms of linear regression according to Fitts’ law, with a correlation coefficient value of over 0.9. Notably, the throughput by ISO 9241-9 of the extended paddle technique peaked at around 1.39 to 2 times higher than in the other techniques, due to the instant 3D positioning of the 3D objects. In the discussion, we subsequently examine the characteristics of the TAR manipulation techniques in terms of stability, speed, comfort, and understanding. As a result, our evaluation process, results, and analysis can be useful in guiding the design and implementation of future TAR interfaces.

An Interactive 3D Movement Path Manipulation Method in an Augmented Reality Environment
Abstract
In this paper, we evaluate a path editing method using a tangible user interface to generate and manipulate the movement path of a 3D object in an Augmented Reality (AR) scene. To generate the movement path, each translation point of a real 3D manipulation prop is examined to determine which point should be used as a control point for the path. Interpolation using splines is then used to reconstruct the path with a smooth line. A dynamic score-based selection method is also used to effectively select small and dense control points of the path. In an experimental evaluation, our method took the same time and generated a similar amount of errors as a more traditional approach, however the number of control points needed was significantly reduced. For control manipulation, the task completion time was quicker and there was less hand movement needed. Our method can be applied to drawing or curve editing methods in AR educational, gaming, and simulation applications.
