Human centered computing and medical data visualization

Computing, communication, and networking have gone through a phenomenal evolution in recent years. Mobile or cell phones embedded with computing power are finding their in roads even in rural population in developing nations. As a result there has been an increased interest in "HCC or Human Centered Computing". HCC is not a new field but a new focus in the analysis, design, development, and deployment of application oriented software systems. Human computer interface (HCI) and user centered design (UCD) focus more at the interface level whereas the scope of HCC is expanded to the software life cycle level with due emphasis to human aspects and it is relatively more interdisciplinary in nature. In the use of computing as a tool, humans work on their own interacting with a computer system or interacting with other humans assisted by the computing infrastructure. As computing becomes ubiquitous, researchers in technology have a social obligation not to ignore the efforts required to bridge the "digital divide" that the computing technology is introducing. Content creation, dynamics of the content, trust on the information, local relevance and sustainability, all these in the context of social development are non-trivial issues. The proposed research in this grant application is a small attempt towards a larger goal of addressing the above issues. We focus on three sample problems that are well defined in scope for an individual researcher. The problems are selected to match, social relevance, feasibility of the experimental approach proposed and the availability of test grounds. The problems addressed are to seek answers to: How to incorporate socio-technical models in software requirements elicitation and engineering? What is the best way to support interacting clinical researchers in their quest to use multiple sources of data in formulating their hypotheses that might lead to discovery? How to empower chronically ill patients by providing right information at the right time in a right manner? Creating appropriate models, integration of models, developing model based design and prototyping, experimental evaluation with real end users are the common themes to these three selected sub problems in the proposed research.
