Abstract : Ubiquitous computing is gradually coming into reality, people use various digital devices (personal computer, laptop, tablet and smartphone) in order to study, work, entertain and communicate with each other. A city is actually a ubiquitous society, citizens get practical information from digital public displays that are installed everywhere in a city: bus station, railway station, airport or commercial center, etc. It seems that we are closing to the vision of ubiquitous computing, however, it’s still far from the vision what Mark Weiser described: the most profound technologies are those that disappear, they weave themselves into the fabric of everyday life until they are indistinguishable from it. That means in nowadays the widespread digital devices are still not intelligent enough and not well integrated, this issue is especially serious under a context of city than for personal usage condition.Smart city is a modern concept of city that seeks to improve the efficiency and quality of life by the information and communication technologies (ICTs), it as well emphasizes the importance of citizens’ knowledge for the wise management of city. The ICTs of a smart city constructs a large scale ubiquitous system, including traffic control systems, public transportation system, energy control systems, etc. In all the systems, digital public displays are one of the most important viewports that connect citizens with city. However, the public display today is only used as a screen to display information, it’s blind to the presence of users and ambient devices, these result in low efficiency of interactions, and make a city unable to take use of citizen knowledge.In this dissertation, we build an intelligent public display by the theory of proxemic interaction. Proxemic interaction is spatial related interaction patterns inspired by the psychological term: Proxemics, it studies the spatial -related interaction human to device and device to device. A proxemic interactive public display means that it is aware of user’s presence, position, movement, identity and other user related attributes, and takes these attributes as implicit inputs for interactions. Besides, it can sense ambient mobile devices and act as a hub for local deices information flows. Compared with traditional public display, proxemic interactive display can provide specific users with more personal related and instant - need information rather than provide general information to all users. That means to make displays sense users instead of making users explore displays exhaustively. These advantages make a proxemic display more adapt to the prospect of smart city.Our object is to study how to address the challenges of public display in a smart city by proxemic interaction. Towards this object, we study the dimensions of proxemic interaction, and build a prototype of proxemic interactive projected display with Kinect, Leap motion and web camera. This prototype supports implicit and explicit interaction of users to provide more personalized contents to users, as well as natural interactions. Furthermore, we developed a toolkit for data migration between public display and personal mobile devices, so that public display becomes aware of ambient users’ devices, users can download resources from public displays freely, while public displays can be as a terminal to collect knowledge of citizens for smart city.We discuss the potential applications of this prototype under smart city, and build an experimental application of proxemic airport flight information board. Based on this experimental application, we organized a systematic laboratory user study to validate whether proxemic interaction can really improve the performance of public displays
