Logitech Bluetooth Cordless Presenter Review 121
securitas writes "Many Bluetooth devices have (deservedly) received dismal reviews and we were prepared for the phaser-like Bluetooth Logitech Cordless Presenter to be another toy headed for the trash-heap of history. Instead we were surprised (some might say stunned :) ) at how well it performed. The Presenter combines a laser pointer, an electronic presentation remote control and a wireless optical mouse in one elegantly designed package."

The point of Bluetooth is that in the future it could work with other things besides just a computer w/ the right drivers.
For instance. A bluetooth TV could let you use it for volume/channel control. A bluetooth projector could let you use it to control its features. A bluetooth system could let you lower/raise the screen. A bluetooth dvd player could give it control...etc. Any bluetooth enabled device that would have a use for a remote or mouse interface could use this.

Assuming you have a correct Bluetooth stack.
Most companies provide one with their adaptors.
Windows XP will include one with the next SP. Linux has the BlueZ-Stack (integrated), Axis Stack and another one I can't remember.

Both must share a common secret (a PIN-code) to enable communication between those two.
But any two devices can (with human intervention) be paired up.
They could conceal the PIN to the user, but why should they?
Another possibilty is to hard code the Bluetooth device address from the Reciever in the sender. But again, why should they do so?
This would only increase the work and costs as they had to flash different programs on the controllers for the benefit of a disgruntled user.
Could you provide a link to back up your statement?
I can't imagine that the Bluetooth SIG would approve this, as it would be detrimental to the goal of Bluetooth.

Reminds me of a lame patent claim, 4,387,297 [164.195.100.11] in which Symbol Technologies claimed a trigger that activated a laser.
They patented a switch to turn on an electrical device.
Good thing the patent expires next year so that Logitech won't get sued...
alternatives (Score:4, Informative)
For under $80, you can get the Keyspan Presentation Remote [keyspan.com], which is smaller, comes with a carrying case, includes a laser pointer, and looks just like a USB mouse from the PC side (no drivers). And, yes, it works with Linux.
Another choice is the Gyration [gyration.com] wireless mice. But their receiver is a bulky box and requires a wall wart. And if you want to be able to use standard AAA batteries, you have to pay $100 extra for the "Pro" version.

How it worked. (Score:5, Informative)
Oh, you don't know how a lightpen works.
A CRT based screen "paints" the image by scanning an electron beam over the display surface. The graphics chip that generates the display knows where the beam is at any time (it has to, since it has to know what pixels to be sending out.)
The light pen (or gun) is a lens that focuses the display down to a point on a fast image sensor (typically a phototransistor). So, when the electron beam paints the part of the screen that the pen/gun is focuses on, the photosensor fires.
This signal is tied back to the graphics controller, which says "AHA! the electron beam is at 234x421 when the sensor fires. I'll record that into these registers".
After that, it is simplicity itself to set up a cursor.
Now, that technique won't work for a liquid crystal display, since they aren't "scanned" in the conventional sense - there is no pulse of light as the system writes the data to the LCD. Therefor, there is no way a light pen or light gun could work on an LCD display like a modern projector.
Now, in theory you could use a camera to sense a laser pointer's spot, and then move the pointer there. But then you would need a fairly high resolution camera, plus a calibration proceedure so the system would know what points on the camera corrisponded to what points on the display. You would also need a fairly narrow band filter to allow the camera (once calibrated) to see only the laser pointer spot - otherwise it might respond to other objects on the display.

Each bluetooth device has an ID, like a network card has a MAC address. In order to get most devices, and I assume the mouse here is the same, you have to pair them up. Once they are paired, they work together, otherwise I'd be on the train on my notebook leeching someone elses bluetooth GPRS connection via an unpaired phone.
Re:Multiple Presenters? (Score:3, Insightful)
My point is merely that two devices shouldn't interfere with one another. And -- assuming that the two devices have different addresses -- yes, each mouse should talk to its designated node, although this may depend on how Logitech actually implements the device and drivers.
Joy. Another "custom" blue tooth adapter. (Score:5, Insightful)
So, this little toy comes with a blue tooth adapter to plug into the USB port. The Microsoft bluetooh keyboard and mouse also have their own adapter.... except some of us have laptops with bluetooth built in, or seperate cards. Why are we ending up with a seperate USB adapter for every piece of hardware?
Re:Joy. Another "custom" blue tooth adapter. (Score:4, Insightful)
This one and the Microsoft devices have a Bluetooth adaptor of their own, because most people don't have one. Not because they need their own.
It's just a matter of marketing. No technical reasons.
I guess they had to make a choice:
Either the disaproval of those few people who have already a bluetooth adaptor and have to pay for the unwanted extra.
Or the disaproval of the people who buy the device and discover that they have to buy another device to make it work.
Or maybe they just thought that there may be people with integrated Bluetooth. Or maybe they didn't think at all.

It would have been great, if they had come out with two separate devices but with some mechanical coupling, so that they can be held together as if it is 1.

If this is correct (or somewhat) why not release the drivers or source 'support free'? I would happily forego tech support for the promise of using devices with other OS's.
Why Bluetooth? (Score:3, Interesting)
One of my favorite bits from the article:
Uhmmm...so, to paraphrase, it's significant because it's hyped. Apparently, there's no reason for it to use Bluetooth, other than the hype. As many others have noted, you can get products that do the same thing for less than half that price, and that don't use Bluetooth.
Re:Why Bluetooth? (Score:1)
Your post takes that quote completely out of context and conveniently ignores the rest of that paragraph and the one that follows, which clearly explain why it's significant that this device uses Bluetooth:
In other words, this is one of the first commercially available devices that has gotten past all of the problems and implemented the Bluetooth standard.
Either you chose to ignore the explanation for some reason or you need to brush up your reading comprehension skills. Either way, read thoroughly and include the context before posting next time.
And as someone else posted here, the reason to use Bluetooth is its range -- have you ever used a 900mHz remote? The signal is inconsistent and anyone with a cordless phone or even a minidisc player can throw off interference that disrupts its operation.
Based on this review, I'm going to check this out.
No idea why it is so expensive (Score:4, Informative)
I still wonder why this device is so expensive. It is possible to get a Bluetooth [arrownordic.com]
baseband controller for 4$ in quantities of 100K pieces (and logitech must order much more than that) with a spec which reads an ARM7 core, 64KB SRAM, 384KB flash and many more things, I cant really comprehend what makes this device so expensive. I mean surely they are using a configuration which maybe costs only half as much. I dont have experience with mouses but I have some experience with more complilcated bluetooth devices, like bluetooth watches with Mpeg4 decoders and stuff like that, and even they cost about 50 USD to make even though they use much more flash and SRAM. So I will say wait for a year before contemplating buying something like this.
