In this paper, we present an overview on recent advances in our work on multimodal human-machine communication between humans and technical cognitive systems in order to enable the solution of complex problems that require the joint cooperation of humans and intelligent systems to accomplish challenging tasks that can be only successfully handled if both interact in a cooperative manner. The te...

Most popular programming languages support situations where a value of one type is converted into a value of another type without any explicit cast. Such implicit type conversions, or type coercions, are a highly controversial language feature. Proponents argue that type coercions enable writing concise code. Opponents argue that type coercions are error-prone and that they reduce the understan...

The web is an increasingly important platform used for a wide variety of tasks on a regular basis. And as the web becomes more important, the ways in which it is used grows increasingly sophisticated. End users build web pages and applications, use web applications in new and unexpected ways and use web macro tools to automate web-based tasks. All of these tasks are error-prone. In addition, th...

In the first article in this series, which appeared in the April!June 2009 issue of IEEE MultiMedia, we presented an overview of using games in the classroom, cited several examples of this approach, and linked the use of games with various cognitive models as they relate to computing education. Most of this work, and the general effectiveness of these approaches with regard to assessment activ...

Google Maps is an intuitive online-map service which changes people’s way of navigation on Geo-maps. People can explore the maps in a multi-layer fashion in order to avoid information overloading. This paper reports an innovative approach to extend the “power” of Google Maps to adaptive learning. We have designed and implemented a navigator for multi-layer social knowledge maps, namely Progress...

Managing information based on hierarchical structures is prevailing, be it by storing documents physically in a file structure like MS explorer or virtually in topic trees as in many web applications. The problem is that the structure evolves over time, created individually and hence reflecting individual opinions of how information objects should be grouped. This leads to time consuming search...

Millenniums ago, Socrates established the basis for philosophy today, only by using criticism to set up concepts and rules discussing them with his disciples. This approach, named Socratic Method, has also proved to be a teaching-learning strategy. Nowadays, even though web-based, collaborative Distance Learning systems are becoming industry standards for representation and deployment of online...

Previous research has indicated that workload can have an adverse effect on the use of speech recognition systems. In this paper, the relationship between workload and speech is discussed, and two studies are reported. In the first study, time-stress is considered. In the second study, dual-task performance is considered. Both studies show workload to significantly reduce recognition accuracy a...

Purpose – The purpose of this work is to analyze the concept of self-regulated learning and applying it to a web-based interface for music teaching. Design/methodology/approach – This work starts from a systematic review about music education and self-regulation during learning processes. Then, the paper identifies thosemeta-cognitive strategies that music students should adopt during their ins...

In many domains such as avionics, railway, and automotive, safety-critical systems must comply with prescribed measures for safety, usually presented in the form of safety standards. Demonstrating compliance with a safety standard involves providing convincing evidence that the requirements envisaged by the standard are adequately met. Real systems are large and thus require collecting and mana...
