This paper addresses a simple question: Is there a behavior pattern of an individual node in peer-to-peer systems? It is known that peer-to-peer systems collectively show daily patterns, but the behavior patterns of i...

Motion detection plays a fundamental role in any object tracking or visual surveillance algorithm and many different approaches exist for motion segmentation. However, recent comparisons show that often basic methods are equivalent to more complex ones and the few existing hybrid approaches that combine frame differencing and background subtraction are surprisingly effective and very fast. We claim, and show quantitatively, that a new hybrid algorithm based on a proper combination of basic methods can outperform many of the most commonly-used methods. It is based on frame differencing and background subtraction, along with a single-Gaussian background model and a maintenance mechanism. We evaluate its performance using existing public benchmark datasets. It is simple, efficient, robust and effective.

Despite the gaming industry's recent trend for using ¿natural¿ interaction techniques, which mimic real world actions with a high level of fidelity, it is not clear how natural interaction techniques affect the player experience. In order to obtain a better understanding, we designed and conducted a study using Mario Kart Wii, a commercial racing game for the Nintendo Wii. We chose this platform due to its seemingly balanced design of both natural and non-natural interaction techniques. Our empirical study of these techniques found that the non-natural interaction techniques significantly outperform their more natural counterparts. We offer three hypotheses to explain our finding and suggest them as important interaction design considerations.
This video demonstrates an application that uses a body-centric approach to support interaction with very large wall displays. The design is centered on a virtual body model that represents the users in the context of...

As a robot formation increases in size or explores places where it is difficult for a human operator to interact, autonomous control becomes critical. We propose a distributed autonomous method for evaluating properti...

Plug-in architectures enable developers to build extensible software products. Such products are assembled from plug-ins, and their functionality can be enriched by adding or configuring plug-ins. The plug-ins themselves consist also of multiple plug-ins, and offer dedicated points through which their functionality can be influenced. A well-known example of such an architecture is Eclipse, best known for its use to create a series of extensible IDEs. In order to test systems built from plug-ins developers use extensive automated test suites. Unfortunately, current testing tools offer little insight in which of the many possible combinations of plug-ins and plug-in configurations are actually tested. To remedy this problem, we propose three architectural views that provide an extensibility perspective on plug-in-based systems and their test suites. The views combine static and dynamic information on plug-in dependencies, extension initialization, and extension usage. The views are implemented in ETSE, the Eclipse Plug-in Test Suite Exploration tool. We evaluate the proposed views by analyzing eGit and Mylyn, two open source Eclipse plug-ins.
We examine the design space of interaction techniques for very large wall displays by drawing from existing theory and practice for reality-based interfaces and whole-body interfaces. We also apply insights drawn from...
