A Secure Behavior Modification Sensor System For Physical Activity Improvement, Alan Price

CGU Theses & Dissertations

Today, advances in wireless sensor networks are making it possible to capture large amounts of information about a person and their interaction within their home environment. However, what is missing is how to ensure the security of the collected data and its use to alter human behavior for positive benefit.

In this research, exploration was conducted involving the "infrastructure" and "intelligence" aspects of a wireless sensor network through a Behavior Modification Sensor System. First was to understand how a secure wireless sensor network could be established through the symmetric distribution of keys (the securing of the infrastructure), and it involves …

Eliciting User Requirements Using Appreciative Inquiry, Carol Kernitzki Gonzales

CGU Theses & Dissertations

Many software development projects fail because they do not meet the needs of users, are over-budget, and abandoned. To address this problem, the user requirements elicitation process was modified based on principles of Appreciative Inquiry. Appreciative Inquiry, commonly used in organizational development, aims to build organizations, processes, or systems based on success stories using a hopeful vision for an ideal future. Spanning five studies, Appreciative Inquiry was evaluated for its effectiveness with eliciting user requirements. In the first two cases, it was compared with traditional approaches with end-users and proxy-users. The third study was a quasi-experiment comparing the use of …
