This product uses the signals to interpret player facial expressions in real-time. It provides a natural enhancement to interaction by allowing characters to come to life. When a user smiles, their avatar can mimic the expression even before they are aware of their own feelings. You can also examine folowing link: http://www.emotiv.com/insight.php

This is really impressive. They have used brain signals to control computer. First Computer learns brain signals (pulling a cube in the screen) when person thinks it, then, a person can use that signal to control anything.

This is amazing. I cannot imagine all the gaming possibilities. Such a system should change the whole human computer interaction in a gaming platform.

Adopting a design-based research methodology, this study used digital video technology to support reflective tasks for language learning in multimedia environments. The emphasis was on the improvement of oral communication skills. The reflective tasks used in this study were exposed to iterative design process and the whole research process was driven by two underlying learning theories. This iterative and theory driven design reflects the nature of DBR well.

Is there ant iteration in the design here? Or is it the implementation of three different courses?

Hocam, students' reflective practice happened in different formats each year. To be more specific, task-completion tools and task-completion formats were exposed to an iterative design. Each year a different tool and a format were implemented and the reflection by the students progressed in an iterative way though it was conducted with different classes. For example, in 2006, students of Class 1 reviewed their presentations in a multimedia player and reflected on it via a word-processing program. In 2008, YouTube was used for their presentations and they had a collaborative reflective task after being paired with each other. So, a different design was applied for each year but in an iterative fashion.
