Creating a layout for an augmented reality (AR) application which
embeds virtual objects in a physical environment is difficult as it
must adapt to any physical space. We propose a rule-based framework
for generating object layouts for AR applications. Under
our framework, the developer of an AR application specifies a set
of rules (constraints) which enforce self-consistency (rules regarding
the inter-relationships of application components) and sceneconsistency
(application components are consistent with the physical
environment they are placed in). When a user enters a new
environment, we create, in real-time, a layout for the application,
which is consistent with the defined constraints (as much as possible).
We find the optimal configurations for each object by solving
a constraint-satisfaction problem. Our stochastic move making algorithm
is domain-aware, and allows us to efficiently converge to
a solution for most rule-sets. In the paper we demonstrate several
augmented reality applications that automatically adapt to different
rooms and changing circumstances in each room.
