It remains a challenge with current state of the art technology to use BDI agents to control real-time, dynamic and complex environments. We report on our effort to connect the Goal agent programming language to the real-time game Unreal Tournament 2004. BDI agents provide an interesting alternative to control bots in a game such as Unreal Tournament to(More)
A mathematical model is presented for comparing geometric and image-based simplification methods. Geometric simplification reduces the number of polygons in the virtual object and image-based simplification replaces the object with an image. Our model integrates and extrapolates existing accuracy estimates, enabling the comparison of different(More)
We have implemented a client/server system for running augmented reality applications on a PDA device. The system incorporates various data compression methods to make it run as fast as possible on a wide range of communication networks, from mobile phone links to WLAN, We provide a detailed description of various implementation issues, data compression(More)
In large ubiquitous computing environments it is hard for users to identify and activate the electronic services that match their needs. This user study compares the newly developed service matcher system with a conventional system for identifying and selecting appropriate services. The study addresses human factors issues such as usability, trust and(More)
Mobile augmented reality requires accurate alignment of virtual information with objects visible in the real world. We describe a system for mobile communications to be developed to meet these strict alignment criteria using a combination of computer vision, inertial tracking and low-latency rendering techniques. A prototype low-power and low-latency(More)
