Emotional Kitchen Appliance - The Nervous Trash Droid
As part of the HCI Interaction Technologies course, this project aimed to challenge the static, emotionless nature of everyday kitchen appliances. The brief called for reimagining a simple kitchen device by embedding an emotional personality into its interface, ultimately creating an interactive physical prototype that conveys a chosen emotion. The project required a combination of interaction design, physical prototyping, and behavioral storytelling.
For my approach, I chose to redesign a mundane yet frequently used kitchen appliance: the trash bin. Drawing inspiration from anthropomorphic robotic characters like R2D2, I conceptualized
“The Nervous Trash Droid”—a bin that exhibits anxious and excitable behaviors in response to user interactions. The goal was to break conventional associations with waste disposal by turning an often-overlooked object into an expressive and engaging presence in the kitchen.
The interaction design was based on exaggerated, non-verbal feedback. When trash is thrown in, the bin responds with a series of nervous rotations, synchronized lid movements, and distinct sound effects, reinforcing its anxious personality. As it reaches capacity, the responses escalate, incorporating more frantic movements and urgent auditory cues.
This project resulted in a pictorial developed as part of my coursework during the Master’s program in Human-Computer Interaction at Paris Lodron University Salzburg. It was not submitted to or published in any academic journals or conferences, but serves as a standalone exploration of the topic through design and visual storytelling.
