    Abstract Preferred Interaction, Don’t Leave Home without It!

    In this paper we restructure the idea of ubiquity, seamless and seamful design into a single collaborative framework. We briefly explore the notions of seamlessness, seamfulness and invisibility in connection to the design of ubiquitous system. Additionally, we also briefly explore the connection of the activity theory to the above notions when we deal with user interaction. This leads to the taxonomy for evaluation of the ubiquitous computing system. One of the purposes of the taxonomy is to clarify the map of notions invisibility, seamless, and seamful. Additionally, the taxonomy shows that one alternative support to the seamfulness is to have the ubiquity in the interaction modal so the user have a degree of independent to have their preferred interaction. This idea is the motivation of the development of the ubiquitous tabletop augmented reality interaction kit in institute FAW. The experimentation on the idea implementation is illustrated. 1

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Flexible Camera Setup for Visual Based Registration on 2D Interaction Surface with Undefined Geometry using Neural Network

    Abstract. Camera setup, calibration and visual based registration of Augmented Reality (AR) based tabletop setups can be a really complicated and time-intensive task. Homography is often used liberally despite its assumption for planar surfaces, where the mapping from the camera to the table can be expressed by a simple projective homography. However, this approach often fails in curved and non-planar surface setups. In this paper, we propose a technique that approximates the values and reduces the tracking error-values by the usage of a neural network function. The final result gives a uniform representation of the camera against combinations of camera parameters that will help in the multi-camera setup. We present the advantages with demonstration applications, where a laser pointer spot and a light from the lamp will be tracked in non planar surface
