Design and Evaluation of a User-Centric Information System: Enhancing Student Life with Mobile Computing
MetadataShow full item record
This project is a continuation of the work carried out autumn 2008 by the author, which reviewed the digital communication channels currently used for distribution of student information at the Norwegian University of Science and Technology (NTNU), and defined the key design decisions for a mobile service called MSIS. The project proposes a new mobile computer system (MSIS) intended to make user-centric information more easily available to students at NTNU. The system is designed using a Service Oriented Architecture (SOA), providing a number of services which offers functionality such as a dynamic course schedule, and a location search tool. Furthermore, MSIS makes use of context-awareness and elements of mobile computing, in order to provide a service that dynamically adapts to the situation of the user. A geographical positioning module based on Wi-Fi location fingerprinting technology is described, which makes it possible to determine the position of a handheld device within existing wireless network infrastructure. The project has been carried out in accordance with the design-science research model over a number of implementation and evaluation iterations. A user-driven evaluation of the MSIS service has been conducted among a group of NTNU students. The utility and usability of the system were evaluated by applying observational and empirical evaluation methods in a real-world environment on campus. The user tests identified numerous issues with the initial design, and suggested ideas for enhancements which have been implemented in the final version of the system. The Mobile Service Acceptance Model (MSAM) has been used to examine the factors that are influential for user adoption of mobile services in light of our project. The MSAM instrument measures different facets of a mobile information service, such as the perceived usefulness, ease of use, and usage intention. Our findings confirm that the utility of the MSIS system is perceived as very high, and students would likely benefit from such a system. There is no doubt great potential for a service like MSIS, and it is believed to be a useful addition to existing systems.
