Tuning devices TAZ

The voting devices developed by the municipal civil engineering office are used for surveys. The aim is to obtain a mood picture for a specific question. With each device, exactly one question can be asked, which offers up to four different answers. Each press of a button is registered by the device and aggregated at 10 minute intervals. This data is transferred wirelessly to a database every ten minutes. The raw data are first aggregated to fixed hourly intervals and then cleaned and analysed. Currently, the voting devices are mainly used for the survey of satisfaction with Piazza Pop-up. The data set contains the locations and the aggregated final results of each survey, before and after the cleanup. **Purpose**: Identification of needs, controlling, impact measurement, general planning basis
