  • Map Navigation Using a Wearable Mid-Air Display
    Map Navigation Using a Wearable Mid-air Display Alexandru Dancu1, Mickael¨ Fourgeaud1, Mohammad Obaid1, Morten Fjeld1, Niklas Elmqvist2 1t2i Lab, Chalmers University of Technology 2iSchool, University of Maryland Goteborg,¨ Sweden College Park, MD, USA fdancu, micfou, mobaid, [email protected] [email protected] ABSTRACT Advances in display technologies could soon make wearable mid-air displays—devices that present dynamic images float- ing in mid-air relative to a mobile user—available. Such de- vices may enable new input and output modalities compared to current mobile devices, and seamlessly offer information on the go. This paper presents a functional prototype for the purpose of understanding these modalities in more detail, in- cluding suitable applications and device placement. We first collected results from an online survey identified map naviga- tion as one of the most desirable applications and suggested placement preferences. Based on these rankings, we built a wearable mid-air display mockup consisting of mobile phone, pico projector, and a holder frame, mountable in two alter- native ways: wrist and chest. We then designed an experi- ment, asking participants to navigate different urban routes Figure 1.

The experiment results validate the use of a wearable mid-air widely accessible [20]. Mobile wearable holographic devices display for map navigation.

  • SHOW ME WHAT YOU MEAN Gestures and Drawings on Physi
    Thesis in Master’s Degree Programme in Industrial and Strategic Design SHOW ME WHAT YOU MEAN Gestures and drawings on physi- cal objects as means for remote collaboration and guidance Andrei Savolainen Aalto University | School of Art and Design 2011 Abstract This thesis presents findings based on the study of remote projected interaction and guidance on physical objects. First, the results are based on the study of literature and previous research in the fields of ubiqutious computing and environment, augmented reality, remote collaboration and guidance. Second, the results are based on findings through testing projector technology in remote interaction and guidance with users with the help of prototype. Previous studies indicate that guidance on physical objects is seen as valuable and in such interaction, the focus should be shifted to the actual object. This thesis contributes to previous research and suggest better integration of hand gestures and drawings into remote collaboration and guidance. Projected interaction model, described in this thesis, enhances the feeling of together- ness between remote users (expert and novice), and provides critical help in conversa- tional grounding in remote collaboration and guidance with physical objects. Keywords Pico projector (also handheld projector, micro projector, mobile projector), remote inter- action, remote collaboration, remote guidance, augmented reality, contextual sensitivity, context-aware, ubiquitous computing, ubiquitous environment, gestures in remote col- laboration and guidance. Acknowledgements I would like to express my appreciation to my tutor, professor Turkka Keinonen from Aalto University and Lutz Abe, a supervisor from Nokia. Thanks for the valuable and con- structive feedback and advises during this process. Also thanks goes to Jussi Mikkonen, Laboratory Manager at Aalto University for the technical expertise with pico projectors and valuable insights.

  • Design and Construction of a Commercial Aftermarket Automotive Head-Up Display
    Design and Construction of a Commercial Aftermarket Automotive Head-Up Display by Donn Eric Pasiliao A thesis submitted in conformity with the requirements for the degree of Master of Applied Science Mechanical and Industrial Engineering University of Toronto c Copyright by Donn Eric Pasiliao 2014 Design and Construction of a Commercial Aftermarket Automotive Head-Up Display Donn Eric Pasiliao Master of Applied Science Mechanical and Industrial Engineering University of Toronto 2014 Abstract The contents of this report provides a comprehensive look at the details involved in the design and development of an automotive head-up display (HUD). By examining the product's complete assembly, including its optics, mechanical assembly, and embedded system, a portable aftermarket automotive HUD was successfully constructed. The resulting product addresses issues and criticisms present in commercially available HUDs, such as display clutter, placement, price, and versatility, giving it a strong competitive advantage within its target market. A brief overview on some performance improvements is also included, followed by recommendations for future actions to advance the developed product closer to commercialization. ii Acknowledgments I would like to thank my supervisor, Professor Ridha Ben Mrad, for providing me with a perfect balance of direction and creative freedom during my M.A.Sc. program. Throughout the course of this project, his guidance allowed me to consistently maintain a strong sense of enthusiasm for the project, even under seemingly insurmountable challenges. Also, I would like to thank the MIE Machine Shop staff (Ryan Mendell, Fred Gebeshuber, Jeff Sansome, Terry Zak, and Keith Hockley) for teaching me practical machining techniques and practices.

  • Unobtrusive Augmentation of Physical Environments
    Unobtrusive Augmentation of Physical Environments Interaction Techniques, Spatial Displays and Ubiquitous Sensing ALEX OLWAL Avhandling som med tillstånd av Kungliga Tekniska högskolan framlägges till offentlig granskning för avläggande av teknologie doktorsexamen fredagen den 5 juni 2009 kl 13.00 i sal E1, Lindstedtsvägen 3, Kungliga Tekniska högskolan, Stockholm. TRITA-CSC-A 2009:09 ISSN-1653-5723 ISRN-KTH/CSC/A--09/09-SE ISBN: 978-91-7415-339-2 © Alex Olwal, juni 2009 ii Abstract The fundamental idea of Augmented Reality (AR) is to improve and enhance our perception of the surroundings, through the use of sensing, computing and display systems that make it possible to augment the physical environment with virtual computer graphics. AR is, however, often associated with user-worn equipment, whose current complexity and lack of comfort limit its applicability in many scenarios. The goal of this work has been to develop systems and techniques for uncomplicated AR experiences that support sporadic and spontaneous interaction with minimal preparation on the user’s part. This dissertation defines a new concept, Unobtrusive AR, which emphasizes an optically direct view of a visually unaltered physical environment, the avoidance of user-worn technology, and the preference for unencumbering techniques. The first part of the work focuses on the design and development of two new AR display systems. They illustrate how AR experiences can be achieved through transparent see-through displays that are positioned in front of the physical environment to be augmented. The second part presents two novel sensing techniques for AR, which employ an instrumented surface for unobtrusive tracking of active and passive objects.

  • Sidebyside: Ad-Hoc Multi-User Interaction with Handheld Projectors
    SideBySide: Ad-hoc Multi-user Interaction with Handheld Projectors Karl D.D. Willis 1,2 Ivan Poupyrev 1 Scott E. Hudson 3,1 Moshe Mahler 1 1 Disney Research Pittsburgh 2 Computational Design Lab, 3 HCI Institute & 4720 Forbes Avenue Heinz College Center for the Future of Work, Pittsburgh, PA 15213 Carnegie Mellon University {karl, ivan.poupyrev, moshe.mahler} 5000 Forbes Avenue, @disneyresearch.com Pittsburgh, PA 15213 [email protected] ABSTRACT We introduce SideBySide, a system designed for ad-hoc multi-user interaction with handheld projectors. SideBySide uses device-mounted cameras and hybrid visible/infrared light projectors to track multiple independent projected images in relation to one another. This is accomplished by projecting invisible fiducial markers in the near-infrared spectrum. Our system is completely self-contained and can be deployed as a handheld device without instrumentation of the environment. We present the design and implementa- tion of our system including a hybrid handheld projector to project visible and infrared light, and techniques for track- ing projected fiducial markers that move and overlap. We introduce a range of example applications that demonstrate the applicability of our system to real-world scenarios such Figure 1: Interacting with the SideBySide system. as mobile content exchange, gaming, and education. each other in shared interactive spaces.
