A couple of students at Munich University have invented a gadget that was conceived, as device, that help people become healthier. If you decide to change your life for the better and spend less time in front of the monitor, but it’s difficult to do yourself, "personal energy ball" is just for you. Personal Energy Orb is based on the computing platform Arduino and determines how much time the user spent the games or the Internet. The creators of the gadget uses the term "virtual energy level" by which they mean the ratio of time spent at the computer, and a healthy physical activity. If this level is reduced, the device begins to turn red, and over time the color becomes more intense. In addition, the gadget is able to gradually change the mouse resolution to the lowest rate, which not only can cause irritation, but also let the user know that it is time to at least make light exercise.
