The Mix & Match ML toolkit was developed during the last year of my master Industrial Design at the Eindhoven University of Technology. Originating from the observation that ideating with AI/ ML is very difficult as there are so many possibilities, I started designing a toolkit that could provide just-in-time knowledge to designers in a playful manner. Leveraging the advantages of Tangible User Interfaces, I embedded the constraints of the types of ML into the shapes of the tokens. The tangible tokens are sensorized and once placed on a sensor board, information, and examples are shown on a web interface. Since designers mainly understand ML through exemplars, real application examples are included for each combination of data and ML capability.
