Although Tangible User Interfaces are considered an intuitive means of human-computer interaction, they oftentimes lack the option to provide active feedback. We developed ‘Sensators’: generic shaped active tangibles to be used on a multi-touch table. Sensators can represent digital information by means of ‘Sensicons’: multimodal messages consisting of visual, auditory, and vibro- tactile cues. In our demonstration, we will present Sensators as suitable tools for research on multimodal perception in different tangible HCI tasks
