Augmented reality for STEM learning: A systematic review

Abstract: This study presents a systematic review of the literature on the use of augmented reality technology to support science, technology, engineering and mathematics (STEM) learning. It synthesizes a set of 28 publications from 2010 to 2017. A qualitative content analysis is used to investigate the general characteristics of augmented reality applications in STEM education, the instructional strategies and techniques deployed in the studies reviewed, and the evaluation approaches followed in the interventions. This review found that most augmented reality applications for STEM learning offered exploration or simulation activities. The applications reviewed offered a number of similar design features based on digital knowledge discovery mechanisms to consume information through the interaction with digital elements. However, few studies provided students with assistance in carrying out learning activities. Most of the studies reviewed evaluated the effects of augmented reality technology in fostering students' conceptual understanding, followed by those that investigated affective learning outcomes. A number of suggestions for future research arose from this review. Researchers need to design features that allow students to acquire basic competences related with STEM disciplines, and future applications need to include metacognitive scaffolding and experimental support for inquiry-based learning activities. Finally, it would be useful to explore how augmented reality learning activities can be part of blended instructional strategies such as the flipped classroom.

Sensetable: a wireless object tracking platform for tangible user interfaces

Abstract: In this paper we present a system that electromagnetically tracks the positions and orientations of multiple wireless objects on a tabletop display surface. The system offers two types of improvements over existing tracking approaches such as computer vision. First, the system tracks objects quickly and accurately without susceptibility to occlusion or changes in lighting conditions. Second, the tracked objects have state that can be modified by attaching physical dials and modifiers. The system can detect these changes in real-time.We present several new interaction techniques developed in the context of this system. Finally, we present two applications of the system: chemistry and system dynamics simulation.

View management for virtual and augmented reality

Abstract: We describe a view-management component for interactive 3D user interfaces. By view management, we mean maintaining visual constraints on the projections of objects on the view plane, such as locating related objects near each other, or preventing objects from occluding each other. Our view-management component accomplishes this by modifying selected object properties, including position, size, and transparency, which are tagged to indicate their constraints. For example, some objects may have geometric properties that are determined entirely by a physical simulation and which cannot be modified, while other objects may be annotations whose position and size are flexible.We introduce algorithms that use upright rectangular extents to represent on the view plane a dynamic and efficient approximation of the occupied space containing the projections of visible portions of 3D objects, as well as the unoccupied space in which objects can be placed to avoid occlusion. Layout decisions from previous frames are taken into account to reduce visual discontinuities. We present augmented reality and virtual reality examples to which we have applied our approach, including a dynamically labeled and annotated environment.

A Procedure for Developing Intuitive and Ergonomic Gesture Interfaces for HCI

Abstract: Many disciplines of multimedia and communication go towards ubiquitous computing and hand-free- and no-touch interaction with computers. Application domains in this direction involve virtual reality, augmented reality, wearable computing, and smart spaces, where gesturing is a possible method of interaction. This paper presents some important issues in choosing the set of gestures for the interface from a user-centred view such as the learning rate, ergonomics, and intuition. A procedure is proposed which includes those issues in the selection of gestures, and to test the resulting set of gestures. The procedure is tested and demonstrated on an example application with a small test group. The procedure is concluded to be useful for finding a basis for the choice of gestures. The importance of tailoring the gesture vocabulary for the user group was also shown.

Fundamentals of Wearable Computers and Augumented Reality

Abstract: Data will not help you if you cant see it where you need it. Or cant collect it where you need it. Upon these principles, wearable technology was born. And although smart watches and fitness trackers have become almost ubiquitous, with in-body sensors on the horizon, the future applications of wearable computers hold so much more. A trusted reference for almost 15 years, Fundamentals of Wearable Computers and Augmented Reality goes beyond smart clothing to explore user interface design issues specific to wearable tech and areas in which it can be applied. Upon its initial publication, the first edition almost instantly became a trusted reference, setting the stage for the coming decade, in which the explosion in research and applications of wearable computers and augmented reality occurred. Written by expert researchers and teachers, each chapter in the second edition has been revised and updated to reflect advances in the field and provide fundamental knowledge on each topic, solidifying the books reputation as a valuable technical resource as well as a textbook for augmented reality and ubiquitous computing courses. New Chapters in the Second Edition Explore: Haptics Visual displays Use of augmented reality for surgery and manufacturing Technical issues of image registration and tracking Augmenting the environment with wearable audio interfaces Use of augmented reality in preserving cultural heritage Human-computer interaction and augmented reality technology Spatialized sound and augmented reality Augmented reality and robotics Computational clothing From a technology perspective, much of what is happening now with wearables and augmented reality would not have been possible even five years ago. In the fourteen years since the first edition burst on the scene, the capabilities and applications of both technologies are orders of magnitude faster, smaller, and cheaper. Yet the books overarching mission remains the same: to supply the fundamental information and basic knowledge about the design and use of wearable computers and augmented reality with the goal of enhancing peoples lives.
