When the TV screen is the only source of light in a dark room the muscles of an eye are in constant tension which can lead to vision problems. Dark and bright scenes are switching very fast when you are watching a movie. Your pupil reacts to the level of light by changing its size, sometimes from 1 to 8 millimeters, and when it is switching from darkness to light, it takes about 5 sec for a pupil to narrow, and up to 5 mins to increase the size of a pupil when it gets darker. This is exactly why your parents didn’t allow you to watch TV in the dark.

Lightpack can also level the intensity of light in your room by reducing the difference in lighting between dark and bright scenes or completely eliminating it (Prof. Dr. Ir. S.H.A. Begemann of TUe, Netherlands, scientific study for Philips).

Lightpack is an open-source device, which lightens your computer or TV screen to strengthen the presence effect. The device needs to be mounted on your TV or computer screen and to be connected to your GenieTV Mac Mini USB port. The software analyses what you currently have on the screen, be it a movie, a game, or anything else, and sends this information to the Lightpack device which in turn lightens the surface behind the screen with matching colours using the RGB-LEDs available within the Lightpack device and it is a cool addition to you GenieTV media centre.

There are 2 modes of operation Screen Grabbing and Mood Lamp. In Screen Grabbing the software analyzes the image on the screen, calculates the colors, and sends them to your device which then displays these on the screen. In Mood Lamp the software provides monochromatic back-lighting regardless of what happens on the screen. Because the capture does not occur, there is almost no load on the CPU. Recommended to designers and to all those that have to strain their eyes for a long time while examining the details in semi-darkness.

The software is open source, is easy to understand and is being expended into a plugin achitecture that allows notifications. Different coloured lights can notify you of actions like incoming email or chat requests.
