This course involves the way to acquire meaningful data from the real world as a tool of problem finding and solving. The data source ranges from the space, e.g. environment monitoring, objects around us, which play critical role cyber physical systems, to human as the stakeholder of a problem. Different data sources require different ways to extract data from them, and the correct way must be used to acquire meaningful data. This course overviews social surveys using questionnaire technique, environment monitoring using state-of-art sensing technologies, and data analysis/presentation skills that are common to all the different projects.
