This project was made by 3 students of Télécom ParisTech as part of the Embedded Systems course (ELECINF344/ELECINF381 aka ROSE). At the beginning in February 2012 our initial goal was to create a display device using persistence of vision. The main interest of this type of device is that we obtain images carved in our retina but the device is moving so quickly that we cannot see it. Thus our images seem to float in the air.
Many POV devices already exist but they are often limited to simple display patterns, such as clocks or moving text. Some of them can display pictures or videos but these media often have to be preregistered in a memory on the device. We wanted to create a universal device able to display whatever you want whenever you want.
