Creating a Vizard Sensor Plugin

[Vbents]

Another newbie question:

I am trying to make a generic wand device which has an LED light on either end, and one or two buttons for basic input/resetting the user when the lights become switched. Does such a device already exist, in some form?

If not, then I would be interested in buying several more LEDs either from WorldViz or some online retailer. Also, if anyone could suggest a simple way of getting button input, that would be very helpful. I saw that someone has posted an example using serial input, but I wonder if this would be reinventing the wheel for my simple application.

Thanks.
