OBJECTIVE To investigate whether virtual humans produce social facilitation effects. BACKGROUND When people do an easy task and another person is nearby, they tend to do that task better than when they are alone. Conversely, when people do a hard task and another person is nearby, they tend to do that task less well than when they are alone. This phenomenon is referred to in the social psycho...

Mathematical competence can be evaluated by analyzing pauses between strokes that occurring whilst an individual copies equations. These pauses provide a temporal signal that reflects the cognitive effort to process chunks. ‘Centre-click’ interaction with a mouse and response grid on a computer display is introduced as new technique for measuring the temporal chunk signal. Alternative pause mea...

| This paper describes the work currently developed at Heudiasyc and Liia within the Pro-Lab II demonstrator. This project started with the second phase of the European Prometheus/Pro-Art program. Its purpose is to develop an electronic co-pilot to assist the human driver. The global software architecture of the demonstrator, presented in 3], is structured in three main modules: perception , de...

In this article, we describe the first results of two series of experiments. It is the aim of our experiments to compare the performance of novice users working with ı̇∗ models. We compared the results achieved with ı̇∗ diagrams in the traditional notation with the results using the alternative notation which has been suggested by using Moody’s “Physics of Notations” framework. We created two mod...

The behavior of agents in multi-agent systems is hard to control without restricting the agents’ autonomy. Normative organizations have been deployed successfully to deal with this. A core requirement of a normative organization is that norm violations can be observed and dealt with. Due to the distributed nature of multi-agent systems it is often fitting that this is done decentrally. In this ...

The study was designed to determine if spatial location of movement was automatically encoded in memory by children with intellectual disabilities (ID) and typically developing (TD) children. Each participant performed motor exercises at each of four selected locations on a 20X20 m field. The condition variable consisted of intentional position-intentional exercise, incidental position-intentio...

We examined whether children's ability to integrate speech and gesture follows the pattern of a broader developmental shift between 3and 5-year-olds (Ramscar & Gitcho, 2007) regarding the ability to process two pieces of information simultaneously. In Experiment 1, 3-year-olds, 5-year-olds and adults were presented with either an iconic gesture or a spoken sentence or a combination of the two o...

Films at the cinema, at home or on the computer screen are a fundamental part of today’s entertainment culture. The careful listening and watching of foreign films with or without subtitles is often used as an aid for the learning of foreign languages. This paper presents the ongoing development of an entertainment/learning computer based DVD subsystem for the home environment that has been ext...

Stock markets play a fundamental role in the countries’ economies, since they allow companies to raise funds for their investments in technology, expansion or infra-structure by selling stocks to the public. At the same time, stocks are, for the stockholders, important assets that can help to maintain or increase the investor’s wealth for future use, like retirement, education, etc. On the othe...

In this paper, we present the system that aids people in wearing makeup easily and make the process enjoyable. The proposed system is the “Smart Makeup Mirror” device, which is an electronic dressing table that facilitates the process of makeup application. In this system, we place a high-resolution camera on top of a computer display. We developed some functions such as “Automatic zoom to a sp...
