Vision
Mobile computing is naturally complemented by Augmented Reality
(AR), which superimposes computer-generated images onto a
user's perception of the real world via devices such as see-through
or see-around head mounted displays (HMD). As a consequence,
a portable 3D information space becomes available to the user.
Such systems are often combined with position sensing devices
(such as differential GPS) to yield location aware computing,
which associates computer-generated images with arbitrary
landmarks of the real world.
Our aim is to develop a mobile AR system that combines the
following features :
- 3D stereographic display of computer generated images.
This enhances the sensation of seeing virtual objects.
- Direct manipulation and interaction with the virtual objects.
- Instant collaboration with another user wearing another
mobile kit.
- Application and data sharing between a mobile and a stationary
user or two mobile users
We are using standard of-the-shelf equipment as well as industrial
components to assemble our mobile computer kits. This allows
simple and fast experiements with an abundance of user devices
and to deploy them in new, unthought-of ways.
Tracking
Our project partner - the Institute
of Electrical Measurement and Measurement Signal Processing
( EMT ) at the Graz University of Technology - is developing
advanced hyprid tracking systems for the mobile user kits.
These will enable a user to work in a world stabilized system
in an arbitrary environment by relying on natural features
for an optical tracking approach. Combining this with an inertial
tracking system will make it responsive and robust at the
same time.
