By 2050 the world’s urban population is expected to grow by 72%. This steep growth creates an unprecedented urge for understanding cities to enable planning for the future societal, economical and environmental well being of their citizens. The increasing deployments of Internet of Thing (IoT) technologies and the rise of so-called “Sensored Cities” are opening up new opportunities towards forming a profound understanding of the relationship of the citizens with their cities. Dr. Fahim Kawsar, the Director of the Internet of Things research at Bell Labs thinks that while silicon sensing helps us to know our cities quantitatively, it is also important to understand the city qualitatively by capturing the subjective metrics such as citizen well being, perception of safety, trust, cleanliness, friendliness, happiness, etc. In his talk he will explain how Bell labs’ research is addressing this aspect of urban landscape.
