I was one of the early adopters of the Connectix QuickCam for the
Mac back when it attached via serial ports and worked in black and
white. I still have pictures taken through this camera that have
managed to survive my various computer transitions and now reside in my
iPhoto library.
Logitech now makes the QuickCam, and they continue to support the
Mac as much as they can.
Remember when we thought that we would get a slew of peripherals
previously denied us because Apple adopted both FireWire and USB
interfaces? For the most part, that has happened, but in some cases the
Mac plays a second cousin to the PC.
This is what has happened with the QuickCam. We can still use it,
but we don't get to do all the stuff a PC user does.
For example, for videoconferencing: We could use Yahoo messenger but
not MSN messenger or Windows Messenger (natch). Unfortunately the
camera is not compatible with iChat AV, because Apple only supports
FireWire webcams for that application.
The
QuickCam Orbit comes in a box, encased in a plastic shell
nearly as massive as it is. Once you manage to extract it, you find a
ball on the base, another ball containing the camera, and a stem them
you can use to raise the ball closer to eye level.
The gimmick for this particular camera is that you can remotely
direct the camera to pan left and right as well as tilt up and down. It
also sports a "face tracking" feature that is supposed to keep track of
your head movements during video conferencing.
I found the face tracking worked about as well as voice commands on
the Mac. If you don't move too fast and keep your face towards the
camera, it works all right. But if you lean over suddenly, the camera
tends to swing in some random direction and start zooming in and out
until you return.
There is a nice long 9 foot cable. Props for that.
Electronically the QuickCam is essentially a
Pro 4000 with a pan and tilt head. The video quality is
about the same as it was when the first color QuickCam came out, maxing
out at 640 x 480 in video (1280 x 960 larger in still images).
The refresh rate on a 1 GHz TiBook didn't
impress me too much. The thing is a webcam, and it performs like one.
Perhaps I've been spoiled by the faster response time I see with DV
cameras over FireWire. The frame rate is probably better with the
current generation of Macs equipped with USB 2.0.
Zooming is sluggish. If you drag the slider over the edge of the
controller window, it jumps back to where it started instead of
maximizing in the direction you were going. This feels clumsy.
The main problem I have with the camera is the interface. There is a
4-way mouse-clickable arrow interface to activate the pan and tilt. If
you hold the mouse button down, the pan takes a single step and stops.
There are no keyboard equivalents, so you couldn't program a joystick
to control it, which is a real shame for budding robot designers. You
would have to go deeper into the control system and talk to the USB
port directly, I suppose.
The thing is obviously capable of smooth panning, because it does so
when you click the "Home" button. Why can't I do that myself?
We bought the camera to serve as part of a display on the Mars
Rovers. We set ours on top of a Lego™ model of a Mars rover and
voilà, an instant interactive display. It's good for a table at
open house, which is where we intend to use it.
I wish I could embed the video output and controllers in a HyperCard
Stack, but those days are long gone. It would make a great kiosk for a
display, though. Pity.
Installation was simple and quick, although it did require a
restart, which seems a bit rare these days on OS X. At one point
the camera software couldn't find the camera, so I had to reinstall it.
I haven't been able to reproduce the problem, so I'm not exactly sure
what happened.
Overall, at the price I paid (retail is US$129.95) I'm getting more
or less what I paid for. There are cheaper webcams. There are less
expensive FireWire webcams (the iBot comes to mind). You pay a little
for the gimmick, and I wish I had more control over it in a greater
variety of ways. The QuickCam Orbit is so new that Logitech hasn't yet
posted any Mac drivers for it.
is a longtime Mac user. He was using digital sensors on Apple II computers in the 1980's and has networked computers in his classroom since before the internet existed. In 2006 he was selected at the California Computer Using Educator's teacher of the year. His students have used NASA space probes and regularly participate in piloting new materials for NASA. He is the author of two books and numerous articles and scientific papers. He currently teaches astronomy and physics in California, where he lives with his twin sons, Jony and Ben.< And there's still a Mac G3 in his classroom which finds occasional use.
