Abstract
Geosocial networks gather large amounts of voluntarily generated information that can be explored in different contexts, including urban areas. In this sense, we developed the Crowd4City system, which puts together city authorities and citizens focusing on the improvement of their urban spaces. In order to ensure the effectiveness of our proposal, we carried out a usability assessment following the ISO 9241, which covers ergonomics of human-computer interaction. For such, this paper describes a case study using Crow4City in a 3-stage evaluation, involving human volunteers, pre-defined tasks, survey analysis and conformity analysis. The statistical indicators show the usability levels which are useful in the analysis of the user’s challenge and motivation on using such a system.
