This paper discusses a new technique for detecting affective events using Hidden Markov Models(HMM). To map low level features of video data to high level emotional events, we per...
We have developed a technique, Aggregate Towers, that allows geospatial data to be visualized across a range of map scales. We use a combination of data aggregation algorithms and...
This paper discusses semantic interoperability issues in agentbased E-commerce systems. The literature reports various techniques to enable agents to understand the meanings of th...
In tangible learning environments the potential to exploit different physical-digital links increases representational power but also broadens the complexity of design. This paper...
This paper presents early work on the "Jots" system, integrated with the Scratch programming environment, which aims to help learners reflect on their learning processes...
