The conflict of uses of public spaces between tourists and locals. A time-based visualization of uses and characterization of the users.

The use of ICT in public spaces may depend on multiple variables. The hypothesis of the current STSMS was to consider if the variables concerning the built environment, socio-economic context and perception from the users of the open public spaces are significant for evaluating the use of ICT in public spaces. Difference of perception, uses and use of ICT were cross-validated with socioeconomic variables of the respondents. In order to validate the hypothesis data mining and statistical methods on data collection will be used.
In this STSM 4 public spaces in the city of Lisbon were explored. The choice of the 4 cases was based on location, dimension and relation in the urban system between the selected contexts; being in historical area; their potential for attracting tourists; and being used by a multiplicity of actors (e.g. residents, tourists, workers, managers). The four chosen cases where Jardim do Principe Real, Jardim da Estrela, Praça das Flores and Praça da Alegria. They were located in the neighbourhoods of Chiado and Bairro Alto in Lisbon (Portugal).
For each of the cases 5 data sets were collected. First, interviews with local shoppers located in the case areas and some additional expertise. Second, questionnaire surveys for each case were collected from the users. Third, set of observations of types of uses and users, pictures and maps of use were collected. Fourth, a selection of main in news in press about the cases or their surroundings for the last 15 years was collected. And fifth, maps on the services and characterization of their surrounding shops were additionally obtained and developed.
The analysis of the spaces and uses covered different spatial and temporal scales. In the temporal scale the daily usage; medium-term (by interviews with local shoppers, questionnaires and maps and data collection of the surroundings of the cases); and long-term temporal scale (by interviews with local shop owners and press collection of the main news of happenings in the cases and surroundings in the last 15 years) were observed. Regarding the spatial scale, three spatial scales were considered. The smallest scale regarding the cases (collected by observations, questionnaires and interviews with the shoppers); a medium scale regarding their surrounding area (by questionnaires, interviews with shoppers, press collection and maps of the surroundings); and a larger scale on the influence of the case study areas as a system and their influence on the city (by questionnaires and interviews with shop owners).
