This research takes a material-driven design approach in combination with a research-through-design method and draws on theories from HCI like the Tension-and-Release principle, the Expressivity in Interaction framework and the concept of Provoking performing objects. The result is Merlett, a robotic worm crafted from a plastic vent tube that responds to touch through sounds and movements. Merlett communicates suffering and vulnerability, eliciting discomfort and empathy in the user.
