using sensors and video
Dec 15th, 2009, 1:15am  
I am new to processing and was curious if it is possible to play with sensors and video.

for example, a piece of video runs when something is in front of the sensor and when nothing is in front, the video stops.

In order to start a project such as this one, where would the best place to begin be? What would i look for?

Thank in advance.

its actually a combination of 2 questions i answered yesterday.
The first one was, how to play a movie :

and the other one was, "keypress" where he wants to turn things on and off by pressing a key. i did that by setting a boolean variable true/false.
thats actually what you need to do but with your sensors.

but you can first try to make it work with they key press. if the video plays and you can stop and play it, you are almost done. next step would be to add the sensors.

Cedric is totally right. Make your program work with a key press. Then try a sensor. These two are perfectly separable. For seneors, you may check out the electronics board
http://processing.org/discourse/yabb2/board_Electronics.html

Or else I suggest you check out arduino.cc and its forum. Have in mind that you can do anything with processing. But your background may limit you. If you've never done any circuit (resistors or switchs), you're better off not messing around it alone. Find someone willing to help.

An alternative is to use a webcam to detect some movement. the video board may have something for you.

thats a good idea. video tracking is a great way to create some kind of movement sensor without actually dealing with hardware sensors.  there are some libraries arround that do the job.
