Driven by the modern shift from quantity to quality, the concept of Quality of Life (QoL) has been proposed as an indicator to assess “health” not just in the physical sense, but also other qualities of daily living including mental disposition, social connection, and surrounding environment. In this research, the concept is extended to urban planning to assess urban development and operations by quantitatively estimating the QoL of people living in smart cities.

Conventionally, the area and the amount of distributed green spaces and commercial facilities, have been used as general-purpose measures to evaluate cities. These appropriate values are derived from the average values for all the people concerned, and it is not often rightly correlated to the satisfaction of people living there. The aim of this research is to develop and practically utilize a tool that can monitor the daily living and satisfaction of each city resident, and a new urban evaluation metric based on such observations. This is then expected to be used as essential feedback for the development of a smart city, which tends to be technology-biased, such that it is an all-inclusive city closely supporting the daily living of diverse groups of people.
