These scientists wanted to create a special system that can show digital information on the world around us, like in movies or video games. They found that the current devices were too big and didn't show things in 3D very well. So, they made a new system using special designs and smart computer programs. This new system is small, shows colorful images, and makes things look like they are really there in front of you. They used tiny, special surfaces and clever computer programs to make this system work really well. It's a big step forward in making cool 3D experiences that you can wear and take with you anywhere!
