Sound design & Tangible interaction


Let children explore sounds, train their memory and discover the connection between sounds and patterns.


Mimi is a tangible interface for children to explore sounds and related patterns. By using blocks, the user needs to recreate the sound sequences that the computer creates.


In this course I was responisble for creating the physical prototype, designing a sound system fiting childerens ability to comprehend and disect sound sequences and creating the sounds used in the Mimi blocks.

Sound System

The difficulty of creating the soundsytem lies in creating a system that is intuitive, not too easy and not to hard for children to understand. By doing usertests with children that had musical education and children that had none, we aimed to test our first soundsystem with the use of the Wizzard of Oz technique. The aim of this technique is where you fake interactions in a way that the person doing the interactions has the real experience without making a working prototype.

The sequence mode plays the blocks one after the other one from left to right.

The parallel mode plays the blocks at the same time, increasing difficulty for the player.
