That's a pretty slick program. It has a clean interface. What did you
write it in? VB ?
I imagine I can use the camera from Vision Command as a web cam.
Unfortunately I don't know anything about web cam's as far as software goes.
Can you point me in the right direction?
Regarding the java script:
<INPUT TYPE="button" NAME="button1" VALUE="Program 1" onClick='dummy.src
=
WebBrickURL+"X1"+Math.random()'><br>
What is the Math.random() part for? how about the dummy.src? I can barely
spell javascript so I'm curious as to what it is sending to web brick.
I would want to keep a single program running so that I can limit the web
cam (via a rotation sensor) to look at only certain parts of the room
(privacy). The javascript and web brick could be modified to send messages
using SendMessage(). The program running in the RCX could then respond to
them - up, down, left right, open close, etc.
You could also just send commands to activate the motors (like the remote)
regardless of the program running - ideal for a motorized web cam stand.
Thanks and keep up the good work.

| That Math.random is a hack to fool JavaScript into sending messages to WebBrick. Here is how the JavaScript works: First, I make a fake image variable "dummy." When you push a button, JavaScript is given the command to load the image with the image (...) (24 years ago, 15-Sep-00, to lugnet.robotics.tele)
