Reactive scripts are designed to get a exible approach for responsive systems; they are based on the reactive/synchronous approach, well suited to real time programming. A reactive script interpretor is a broadcast event-driven interpretor which can react to several commands in parallel. Generating events and waiting for occurrence of events are the basic commands which are composed in several ...

Collaboration scripts are activity programs which aim to foster collaborative learning by structuring interaction between learners. Computer-supported collaboration scripts generally suffer from the problem of being restrained to a specific learning platform and learning context. A standardization of collaboration scripts first requires a specification of collaboration scripts that integrates m...

Collaboration scripts can help learners to engage in argumentation and knowledge acquisition. However, they might have differential effects for learners holding differently structured knowledge (internal scripts) on argumentation. We investigated how external scripts interact with learners’ internal scripts concerning collaborative argumentation. 98 students from two secondary schools participa...

A representational approach to ecological psychology is presented. This paper identifies a computational-level commonality in ecological psychology research related to passability of apertures. It is argued that a cognitive mechanism capable of comparing the geometric properties of an environment and the geometric properties of the agent can be used to support judgments for action in space.

An alternative view of presence is introduced based on existential philosophy and ecological psychology. This view favors a Heideggerian/Gibsonian metaphysic over the more conventional rationalistic orientation. In this alternative view, notions of subjective presence and objective presence no longer exist. Presence is instead tied to one’s successfully supported action in the environment, this...

According to the 8th schedule of Indian constitution, there are 22 official languages and 122 regional languages prevalent in India. In the last few decades, the recognition of these scripts has been prominent area of research. Among these scripts most of the recognition research work has been done for Bangla, Devanagari, Gujrati, Gurumukhi and Telugu scripts etc. Commercial OCRs were available...
