During the last years, several easy-to-use tools for home planning and interior design have been released. These tools intend to allow users, without specific skills, to create their virtual house, decorate it and navigate in the resulting scenery. In this paper we present three of these applications and describe task analysis using them. As a result of this experiment, we identify user requirements for this kind of tools, along with positive and negative aspects, providing good insights and directions for future work.ComputerAided DesignSketchBased InterfacesUser InterfacesTask AnalysisEvaluation10.2312/pt.20061557225-228
