iOrb - Unifying Command and 3D Input for Mobile Augmented Reality (2004)
Input for mobile augmented reality systems is notoriously
difficult. Three dimensional visualization would
be ideally accompanied with 3D interaction, but accurate
tracking technology usually relies on fixed infrastructure
and is not suitable for mobile use. Command input is simpler
but usually tied to devices that are not suitable for 3D
interaction and therefore require an additional mapping.
The standard mapping is to use image plane techniques relative
to the users view. We present a new concept - the
iOrb - that combines simple 3D interaction for selection and
dragging with a 2D analog input channel suitable for command
input in mobile applications.
The aim of this project is to investigate how two or more users can interact on such tasks as navigation and information browsing/display with the help of Augmented Reality in an outdoor environment. It is based on the hard- and software developed in the Mobile Collaborative Augmented Reality subproject of the Studierstube research project.

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.
