With increasing product portfolios of eCommerce companies it is getting harder for their customers to find the products they like best. A solution to this problem is to analyze the customer's behavior, and recommend products based on ratings. By considering click-stream data, the customer is unburdened with explicitly rating his favored. In this paper, we introduce a system for segmenting visitors and recommending adequate items in real time by using an event-based system called Sense and Respond Infrastructure (SARI) for processing click-stream data. We present the architecture and components for a real-time click-stream analysis which can be easily customized to business needs of domain experts and business users. SARI provides functionality to monitor visitor and customer behavior, respond accordingly and at the same time optimize and adapt customer processes in real time. To illustrate this approach, we introduce a reference implementation, its underlying infrastructure and business scenarios.

This paper introduces a new low-cost pressure-sensitive user input device called "SqueezeOrb". The device is built from an assembly force-sensing resistors embedded in an elastic hand exerciser. A USB-enabled microcontroller continuously samples the sensors, applies a double-exponential noise-reduction filter and streams the resulting "handgrip strength" measurement to an attached host computer at a frequency of up to 1000 Hz. When combined with optical motion-tracking, the SqueezeOrb becomes a pressure-sensing input device for three-dimensional interaction. Copyright 2008 ACM.

We present an augmented reality application for mechanics education. It utilizes a recent physics engine developed for the PC gaming market to simulate physical experiments in the domain of mechanics in real time. Students are enabled to actively build own experiments and study them in a three-dimensional virtual world. A variety of tools are provided to analyze forces, mass, paths and other properties of objects before, during and after experiments. Innovative teaching content is presented that exploits the strengths of our immersive virtual environment. PhysicsPlayground serves as an example of how current technologies can be combined to deliver a new quality in physics education.

Serious games and especially their use in healthcare applications are an active and rapidly growing area of research. A key aspect of games in rehabilitation is 3D input. In this paper we present our implementation of a full body motion capture (MoCap) system, which, together with a biosignal acquisition device, has been integrated in a game engine. Furthermore, a workow has been established that enables the use of acquired skeletal data for serious games in a medical environment. Finally, a serious game has been implemented, targeting rehabilitation of patients with chronic pain of the lower back and neck, a group that has previously been neglected by serious games. The focus of this work is on the full body MoCap system and its integration with biosignal devices and the game engine. A short overview of the application and prelimiary results are provided.

Given the increasing importance of multi-energy carrier system modeling, this paper focuses on modeling the dynamics that occur in natural gas transmission lines. In high-pressure pipelines, these dynamics are governed by a set of hyperbolic partial differential equations. Dissipative finite volume discretization schemes are proposed that honor the discrete maximum principle. The convergence of the proposed discretization schemes is investigated and compared with existing methods suggested in the literature for natural gas transmission such as the implicit cell-centered method. High order time discretization methods are also tested and their suitability with respect to the maximum principle is discussed.

The standard method for estimating the rigid-body motion of arbitrary interaction devices with an infrared-optical tracking system involves attaching pre-defined geometric constellations of retroreflective or light-emitting markers, commonly referred to as "targets", to all tracked objects. Optical markers of the same type are typically indistinguishable from each other, requiring the tracking system to establish their identities through known spatial relationships. Consequently, the specific geometric arrangement of markers across multiple targets has a considerable impact on the system's overall performance and robustness. In this paper, we propose a simple new methodology for constructing optically tracked rigid-body targets. Our practicallyoriented approach employs an optimization heuristic to compute near-optimal marker arrangements. Using prefabricated mounting fixtures, the assembly step requires only basic hobbyist tools and skills. Copyright 2008 ACM.
