Music table

How does the exhibit work?

Put the headphones on. Place the tiles in the centre of the circle. Place them with the image of the blob-figure face down.

Do you hear sound through the headphones? By combining or rotating different tiles, you can create music.

What is the science behind it?

Anyone can make music. That's what the makers of this musical instrument, the Reactable, wanted to prove, among other things. Give it a try. By placing a blue square cube - with the blob figure facing down - on the playing surface, you will hear a sound. The other cubes change that sound in different ways.

How it works? Well, under the playing surface is a camera that films the cubes on the table. The camera images then go to a computer. Which, thanks to artificial intelligence (AI), recognises which image is on the cubes, where the cubes are located and in which direction they are rotated. And like this the computer knows what sound should come out of the speaker and what animations the projector should show.

What do you think: can everyone make music?

AI in the forest

What is that animal you spotted in the forest? You can quickly find out with the free photo-recognition app Obsidentify. You take a photo and the app - thanks to AI - tells you which animal is on it. It also works with plants and mushrooms.

The best thing about it? You also help science with it. Your observations are part of research on those species. Every observation counts!

AI on a trip

Travelling is fun. But talking to children who don't speak English is not easy. The solution? A translation app like Google Translate or Deepl Translate! Speak in what you want to translate and AI transforms it into the language of your choice.

AI at the doctor's office

Detecting cancer in scans? Doctors can now turn to AI for that too. There are AI systems that can spot cancer at an early stage. They have learned this by first analysing a lot of scans. Handy, because that way people are helped quickly.
