Augmented Urban Planning Workbench: Overlaying Drawings, Physical Models and Digital Simulation
“Luminous Table”: Augmented Reality Workbench that integrates multiple forms of physical and digital representations.
2D drawings, 3D physical models, and digital simulation are overlaid into a single information space in order to support the urban design process.

Inexpensive Non-Sensor Based Augmented Reality Modeling of Curves and Surfaces in Physical Space
Adrian David Cheok,Neo Weng Chuen Edmund
and Ang Wee EngNational University of Singapore
Augmented reality system where a user can model surfaces with his hands, and without expensive sensing systems.
The system uses computer vision based methods for the tracking of the user’s head and hand position.
Using a glove and the tracking system, the user can draw smooth lines or surfaces with her hands in a physical space.
MagicCup: A Tangible Interface for Virtual Objects Manipulation in Table-Top AR
City-planning system based on augmented reality with tangible interface.
Tangible interface for virtual object manipulation in table-top augmented reality based on ARToolKit.
User holds a transparent cup upside down and can pick up, move or delete a virtual object by using it.

Mediated reality describes the concept of filtering our vision of reality, typically using a head-worn video mixing display.
Proposes a generalized concept and new tools for interactively mediated reality.
First prototype system for painting, grabbing and glueing together real and virtual elements.
Collaborative Augmented Sketching
Software prototype using AR Toolkit for collaborative augmented reality sketching in architectural design.
Non-intrusive interaction technique developed for this prototype.
Sketching and distribution mechanisms are discussed and illustrated.

Collaborative Mixed Reality Visualization of an Archaeological Excavation
Hrvoje Benko,Edward W. Ishak,
Steven FeinerColumbia University
VITA (Visual Interaction Tool for Archaeology) tool. Experimental collaborative mixed reality system for
offsite visualization of an archaeological dig. System allows multiple users to visualize the dig site in
a mixed reality environment. Tracked, see-through, head-worn displays are
combined with a multi-user, multi-touch, projected table surface, a large screen display, and tracked hand-held displays.

Mix It
ADETTI. Visual interface for authoring AR/MR. Magic Book metaphor. Books are made of markers and associated 3D models. Editor + AR Viewer. Virtual Flashlight live demo.
AMIRE
A Mixed Reality Authoring tool. The main objective of AMIRE is to enable non-
expert researchers: to use Mixed Reality (MR) for their applications to create and modify these MR applications
with the support of dedicated tools that foster an efficient authoring process for MR.

Authoring of a Mixed Reality Assembly Instructor for Hierarchical Structures
Mixed Reality based step-by-step furniture assembly application.
Context related actions are given to the user to install elements.
Intuitive way for authors to create new MR based assembly instructions.

DART: The Designer’s Augmented Reality Toolkit
Designer’s Augmented Reality Toolkit (DART). Allows users to easily create augmented reality (AR)
experiences. Can be used by technologists, designers and students
alike. Rapidly prototype AR applications without extensive
programming and content creation as well as knowledge of technical topics involving cameras, trackers, and 3D geometry.

Immersive Authoring of Tangible Augmented Reality Applications
New approach for authoring tangible augmented reality applications, called ‘immersive authoring.’
Allows the user to carry out the authoring tasks within the AR application being built.
The development and testing of the application can be done concurrently throughout the development process.

DesignAR
DesignAR allows a way of authoring augmented reality environments without needing to write code in C++ or other programming languages.
The environment centers around Touch Designer, a commercial 3D modelling package by Derivative.

User requirements
Project partner (User Requirements): NOA - Design agency in Germany. Develops modern 3D products in the context of market,
communication, technology and production.
Specification of the core technology: MxToolkit Handles user interaction, hardware interfaces, system management, etc Independent of application to be developed; provides generic programming
language mechanisms for VR/AR/MR applications. Specification of a new AR authoring tool: Performance Plaza
Based in MxToolkit. Geared towards designers and 3D artists. Proposes a visual and intuitive new Human-Computer Interaction technique.
Two different work paradigms: design and presentation Design: interactively prepare 3D models for presentation. Presentation: show and interact with 3D animated models in AR.
User requirements
Design phase: Highlight and select subscenegraphs of
3D models. Transform, measure, cut and change
appearance of models. Insert text and voice anotations. Allow model version control based in
product development timeline. E.g.: problem level model, concept level model, design level model, realization level model.
With these operations author a “powerpoint-style” 3D presentation:
Timeline based. User’s (designer, architect, engineer,
marketeer) actions trigger events. Create automatic or event-based
animations.
User requirements
Presentation phase: Users interact with models (view, pick, move around, etc). Arrange models in a life-situation. Show or hear, select and change text and voice annotations. See/switch between time-related and speciality-related
(architect, designer, engineer, marketeer) model versions. Launch presentation prepared in Design phase; trigger events
and animations.
System architecture
Hardware Peripherals: webcam(s), microfone, speaker. Input devices: human hand, AR fiduccial marker(s), keyboard (or equivalent for
text anotations). Output devices: computer monitor, HMD, “Paycheck” screen.
