The designer places 2D graphic visualisations or 3D objects within an environment to stimulate discussion and elicit a response from the user. These designed elements take the form of interventions or provocations within the research process, engaging a person’s imagination and encouraging a fuller response in ways that more formal interview and questionnaire techniques cannot achieve. Interventions can include futuristic prototypes that express new ideas; provocations can include shock imagery or incongruous juxtapositions.
