1. Public and private space
Public space is defined as an area where everyone, regardless of his or her background, can enter without prerequisite, while Private space are spaces which are owned by particular groups or individuals but not the community, and are meant for private use. However, private ownership does not necessarily mean a space is exclusively for private use. There are also privately owned public spaces(POPS), which exist due to requirements on the lease or simply business decisions.

The use of ICT can form a more intelligent use of public space. The Hong Kong Smart City Blueprint by the HKSAR suggests a trend of using ICT to improve the city. Hence, this part is looking into how current and possible future use of ICT in the study area.
