Interactive video

An idea I’m thinking for some time now: the possibility to implement a solution that will allow a video player (software) to be able to control lights and objects. It would be useful for installations as an experience. The project could develop to an interesting “out of home” advertising platform. Not that it not existent today, but it would de certainly be a helpful thing. I’m sure that there are some options on the market. But such idea would simplify the way a video can interact with real objects. Thinking more of films as software apps that could interact with the lights of your house or maybe your devices and so on. That could be very interesting. I will do some tests and I should publish somethign soon.

For that purpose I could use a simple DMX dimmer pack:

A dimmer pack is a collection of dimmers used to DIM, or change the intensity of the lights in a theatrical show. Dimmer packs come in many varieties, from budget (anything from £50) right up to the high end stuff (up to about £3000). They are commonly controlled remotely from the lighting control console via either 0-10v analogue, or (more commonly these days) DMX-512.

An ideal dimmer changes only the intensity of the light, leaving all other attributes unchanged. Most dimmers lower the voltage to the light, which also causes the light to shift to the warm/red end of the spectrum because the filament cools. Some modern lighting instruments include a dimmer in the instrument (either mechanical or electrical) and do not require a dimmer pack. Most dimmer packs also distort the sinusoidal waveform of the AC voltage and can cause noise and problems if connected to motors. Some special dimmers produce true sine wave output.
