Sony Xperia Touch

By: Aafreen Ali

The Sony Xperia Touch Projector is a portable projector that transforms the surface projected on into a high-definition touchscreen. Unbelievable, right? The projector uses infrared technology and presence sensing to sense how you are manipulating the projected image and changing the image based on your actions, just like a normal touchscreen. It also uses short-throw projection to display the images. The Xperia Touch also has Wi-Fi capabilities.

This relates to engineering because it is the first of its kind. The engineers at Sony had to solve many problems, such as how the image would respond to touch and how they could fit all of the parts into such a small receptacle.
