Naru
A client asked us to design a screen-free sensory toy for children aged 3–6, using NFC, projection and audio to create interactive experiences. The product needed to be safe, calming, child-operated and portable, with a target cost of around £100.
Taking inspiration from the client’s feedback and exploring simple, recognisable shapes, we developed the idea of a volcano. This evolved into Naru — a volcano-shaped, screen-free sensory projector and speaker. Children can independently use NFC cards or characters to change the projected visuals and matching sounds, creating calming sensory experiences without needing a phone or parental assistance.
Design Process

Sketch
We developed different concepts based on the required components, using a design matrix and client feedback to select the strongest ideas.

Prototype
We created prototypes to explore different ideas, gather client and group feedback, and narrow down the final concept.

Testing
We tested the design through physical prototypes, FEA, calculations and component testing to ensure everything worked together.

Final
We manufactured and assembled the final components. More cost-effective materials were used where the original components were too expensive for the client.
Final Design
The final Naru design combines a volcano-inspired form with a projector, speaker and NFC system. Children can use interchangeable NFC cards or characters to independently change the projected visuals and matching sounds, creating calming sensory experiences without needing a phone or parental assistance. The final design was developed to be simple, engaging and easy for children aged 3–6 to use.
