Human computer interaction (HCI) is currently aimed at the design of interactive computer applications for human use while preventing user frustration. When considering the nature of modern computer applications, such as e-learning systems and computer games, it appears that human involvement cannot be improved only by using traditional approaches, such as nice user interfaces. For a pleasant human involvement, these computer applications require that the computers should have the ability to naturally adapt to their users and this requires the computers to have the ability to recognize user emotions. For recognizing emotions currently most preferred research approach is aimed at facial expression based emotion recognition, which seems to have many limitations. Therefore, in this paper, we propose a method to determine the psychological involvement of a human during a multimedia interaction session using the eye movement activity and arousal evaluation. In our approach we use a low cost hardware/software combination, which determines eye movement activity based on electrooculogram (EOG) signals and the level of arousal using galvanic skin response (GSR) signals. The results obtained using six individuals show that the nature of involvement can be recognized using these affect signals as optimal levels and distracted conditions.

Source-code that a developer writes may not definitely make sense to another, the understandability of a source code depends on the proficiency in the language and the logical thinking pattern of the person who has developed the code and who tries to understand it.   However, in distributed software development and in software maintenance there is a need to read and understand the source-code probably written by someone else after some time it has encoded.  Flowcharts are used to depict the logical flow of processes and can be used as an effective tool in representing the control flow of software programs. This paper presents a novel approach to generate flowcharts from program snippets. It demonstrates that by using an intermediate abstract representation, independent of any programming language, the generation of flowcharts for programs written in any programming language can be achieved. The feasibility of the proposed approach was demonstrated by developing a porotype system of compilers to generate flowcharts for source-codes written in the PHP language.
