Semiotic thinking about cities, that is through the prism of their ways of representing various meanings, symbolic values and communication in this text is set into the framework of the User Experience (UX) Design. The primary aspect through which the city is perceived is the appropriation of public spaces by two different communities: Experts and Users - two groups engaged in daily communication situations within a city.
Design and appropriation are viewed as a tool for modulation of a language of the city. While it is the inhabitants who use the city, and thus define it, experts exercise the power of setting communication norms and have the responsibility for the User-Centered Design approach in built environments.
Elements of the "Language of the City" concept are explored and offered in a perspective of the User-Centered Design.
