Tangible user interface

Tangible User Interface is a way that we can interact with computers, just like we interact with toys or other things we can touch and feel. Imagine you have a toy in your hand, you can touch it, move it around, and it responds to your actions. In the same way, a tangible user interface allows us to interact with the things we see on the computer screen by touching and manipulating physical objects.

For example, if you wanted to draw a picture on the computer using a tangible user interface, you would have a pen that you could hold and use like a real pen on a piece of paper. The computer would recognize the pen movements and translate them to the computer screen, so that you could see your drawing there, as if you had drawn it with a real pen.

Another example of a tangible user interface is a game that you can play on a tabletop. You would have physical game pieces that you could move around on the table and the computer would recognize the movements and change the game accordingly. This makes playing games much more engaging and interactive, like playing a board game in real life.

Overall, the idea behind a tangible user interface is to make computers more like real objects, so that we can interact with them in a more intuitive and natural way.
