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.

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.

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.

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:
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.
