Interactive Display - iBar

I first came across the iBar on BBC World’s program called >Click, which talks about the latest developments in the world of technology. The iBar is a system for the interactive design of any bar-counter. Integrated video-projectors can project any content on the milky bar-surface. The intelligent tracking system of iBar detects all objects touching the surface. This input is used to let the projected content interact dynamically with the movements on the counter. Objects can be illuminated at their position or virtual objects can be ‘touched’ with the fingers. The interactive surface may show corporate logos from certain brands for promotional purposes. Alternatively, the iBar could show more visually stimulating images such as water effects where the person interacting with the surface would leave an impression behind. Other visual images include flowers and butterflies, where the butterflies follow the person’s hand, or even a glass that may be on top of the bar. This concept really fascinated me, and it looks amazing. However there isn’t much information on how the iBar exactly works, for example the use of any sensors it uses. But I will keep checking for any new information.
