Traces: Studying a Public Reactive Floor-Projection of Walking Trajectories to Support Social Awareness

Research output: Contribution to conferenceAbstractScientificpeer-review


Research units


Walking trajectories have been used to understand how users interact with public displays. However, it has not yet been studied how displaying them in-situ could affect users’ awareness about others’ presence and activities. We present the study of an interactive public floor-projection called Traces. Traces projects the walking trajectories of individuals as they pass through the lobby of a university building. We investigated Traces through a 6 week in-field study. Our results outline how different uses and understandings of Traces contributed towards its appropriation as a glanceable display for social awareness. We outline design suggestions that future designers should consider to support social awareness with public displays.
