User 25.04.2007 08:09:01 | wii remote ir calibration | |
This posting is older than 6 months and can contain outdated information. I'm not able to calibrate the wii ir mouse feature ( build RC2). It
seems as though the ir is not bright enough. If that makes sense? I
can calibrate to a bright light source, but then I have to point the
wii at the light bulb to get the cursor to move on the screen. I've
tried close up to the tv and mac mini (same place really, right next
to each other). Any ideas or thoughts would be appreciated. Also
kudos for the ability to change the length of time the song display
window stays on. Thanks.
| These entries from the FAQ may be relevant to this topic: Hardware - Apple® Remote
To enable you to use all capabilities of the IR Receiver of your Mac®, Remote Buddy is using its own driver. In contrast, all other applications with integrated Apple® Remote support usually use the OS X Apple® Remote subsystem.
As long as you're running Remote Buddy, Remote Buddy and its driver are responsible for turning the received button presses into actions. As soon as you quit Remote Buddy, this task is again handled by the OS X Apple® Remote subsystem.
If other applications don't use the interface to the OS X Apple® Remote subsystem correctly, this can lead to the effect that nothing happens when you press a button on your Apple® Remote. For as long as you're running Remote Buddy, issues like this are covered by Remote Buddy and it's driver and are therefore not visible to you. However, as soon as you quit Remote Buddy, the OS X Apple® Remote subsystem is back in control and any issues caused in it by other applications become visible.
Therefore Remote Buddy is neither the cause of the issue nor is it responsible for it. Instead, the cause of the issue exists independently of Remote Buddy. It's located elsewhere and can also only be solved there.
Although our products can't cause any such issues, we're regularly contacted about such issues and asked for help. In order to make locating and fixing the cause of such issues as easy and efficient as possible, we've developed a free diagnostics tool: Remote Control Diagnostics. It can locate issues with a single click and will provide you with information about the issue as well as with instructions on how you can fix it.
Hardware - Wii™ Remote The calibraton function does not serve the purpose of adapting the sensor to low power IR light sources nor does it in any way influence the communication with the Wii™ Remote or change its settings in any way. It is purely a function of the driver, which should only be used if you can not reach one or more borders of your screen.
When in mouse mode, the position of the mouse pointer on the screen is determined by where the sensor field in the front of the remote recognizes the infrared light source. If objects are hindering the path between remote and sensor, the borders of the screen can no longer be reached.
This is exactly where the calibration function kicks in. Using it, you can intuitively determine which area of the sensor should be used to interpolate to your screen coordinates. Therefore, start calibration and follow the instructions on the screen. The goal is to maximize the size of the rectangle on the screen with your movements.
Built into the Wii™ Remote is an infrared sensor, that can locate several, punctual infrared light sources and report their location to Remote Buddy.
It's impossible to determine the position of the remote control - and thus also moving the mouse cursor - without at least one of these infrared lightsources.
When using the game console, the so called sensor bar is supplying this IR light source. The name is a bit misleading, as it does not contain any sensors at all, just IR diodes, that emit light in the IR spectrum - which is invisible to the human eye.
If no sensor bar is available to you - or if the IR diodes in it are currently turned off, another infrared light source is required. Infrared radiation is also called heat radiation. Simply said, when there's heat, there's infrared light, too. Using this physical phenomena, you can also use very hot objects as infrared light source - whereas f.ex. tealights and candles are especially predestined. Always make sure to exclude the possibility of a fire and any other risks, when using burning candles, tealights or very hot objects,
An infrared receiver can not be used as infrared lightsource. It can only receive, not emit infrared light.
TV sets and monitors don't create light in the infrared range that would be strong enough, either.
In order to use the infrared mouse mode, you have to point your remote control to the IR lightsource. You can easily check, whether this source is strong enough by having a look at the options of your remote in Remote Buddy's preferences (in the Hardware tab). There, all light sources recognized by the IR sensor are displayed for as long as the IR mouse mode is active.
You can find more information on infrared light on f.ex. Wikipedia (Link to external article).

This posting is older than 6 months and can contain outdated information. Hello Casey, hi Craig, that makes perfect sense. You need a strong IR light source like a
tea light or candle. Your Mac Mini or TV shouldn't emit much if any
IR light / great heat and would probably also be too massive as that
they could be used as a - literally - hot spot for the Wiimote to
recognize. The calibration does only kick in after you already have a IR source
that is strong enough. It allows you to determine in which range you
want to move the cursor across the screen. But you'll usually not
need that as Remote Buddy is preconfigured with values good for
almost every purpose. You can (ab)use calibration to also see what your IR sensor is
seeing, though. Alternatively, you can also do this by pressing
button 1 to activate/deactive the IR mouse mode. What calibration doesn't (and can't) do is to change the sensitivity
of the IR sensor. Hardware wise it's possible to adjust it, but you'd
still need a proper IR source, so it wouldn't be of help here either. Hope that helps. Best regards,
Felix

This posting is older than 6 months and can contain outdated information. Hi Felix,
Thanks for the reply. I guess I wasn't clear on what caused me to try and calibrate the wii remote ir. The cursor doesn't move at all (motion sensitive wise) after I pair the remote. The only way to get the cursor to move is to choose virtual mouse and use the pad keys. I gather from your reply that the motion sensing cursor movement should just work after pairing. (Yes I have tried the toggle (1) button) So my question is, how do I get the ir motion sensing to work, because the only way I can get the cursor to move via motion is to calibrate to a very bright light and then I have to point the wii remote at the bright light (not the screen) to get the cursor to move on the screen.
Thanks,
Casey

This posting is older than 6 months and can contain outdated information. Hello Casey, thanks for the follow up. The InfraRed light source (and infrared light is also emitted at
great heat - that's why a candle is working and a TV isn't) is
*required*. The motion / accelleration sensors aren't used by Remote
Buddy at this time and would probably also not be accurate enough to
allow accurate mouse movements. For more background info on this,
here's an interesting read: http://www.wiili.org/index.php/Wiimote#IR_Sensor I've implemented support for the IR sensor starting with a battery of
candles on the desk in front of the screen and finally cutting down
Remote Buddy's candle needs to one candle - which is a world premiere
as far as I know ;-) And, as said, the calibration has nothing to do with the intensity an
IR light source has to have. It just allows you to define a different
rectangle to be used for tracking. My advice: light a candle, place
it in a safe place where it can't have any potential to burn down
your place, then go into Preferences, activate mouse mode or
calibration and have a look at the options for the connected Wiimote
while pointing it to the candle. That's a good way to understand how
the whole InfraRed sensor / mouse mode works. Best regards,
Felix

This posting is older than 6 months and can contain outdated information. Hi Felix, That makes a lot more sense. Keep up the good work. Thanks for the fast replys and GREAT support!!! P.S. I was just having my morning coffee while reading your (fast) reply and it crossed my mind, that probably in a future release, Remote Buddy will support my coffee maker too. ;-) This program amazes me!!!

This posting is older than 6 months and can contain outdated information. hi,is it possible to adjust sensibility of the IR mouse?
the cursor trembles a lot, and i cant seem to click on icons, i keep dragging them accidently :S
Is it because im using a candle and not a IR emitter?

This posting is older than 6 months and can contain outdated information. Hello Fillipe, thanks for asking. In fact Remote Buddy already has an algorithm to keep the cursor from
excessive turbulences ;-) I'll certainly work on the improvement of this algorithm, though. Best regards,
Felix

This posting is older than 6 months and can contain outdated information. Hi Felix, While I have had good performance using the candle method, I was wondering if you think a home-made USB-powered LED IR device would work, something like this:

I've implemented support for the IR sensor starting with a battery of candles on the desk in front of the screen and finally cutting down Remote Buddy's candle needs to one candle - which is a world premiere as far as I know ;-) Yes, but with only one IR source the control is not very good, and in the calibration process i can't set properly each edge screen. With two source is better, because there is a differential information, so the control is more "smooth" and precise. However, sometime i use my webcam with infrared led and it works. If your monitor is on a desk, put the IR source on the border of the desk for better control Last edited: 13.05.2007 16:14:21

This posting is older than 6 months and can contain outdated information. Hello Steve, I guess pretty much anything that roughly takes the form of a spot
and emits a sufficient amount of light in the infrared spectrum
should work. There's also a ready-made (but not cheap by far
considering the simplicity of the construction and the low cost of
its elements) sensor bar replacement available from Nyko (and
available through amazon.com): http://www.nyko.com/nyko/products/?i=101 This construction is also quite clever (but no longer available as
far as I can see): http://gear.ign.com/articles/751/751096p1.html Have a close look: it seems to take standard DYI-market elements and
should be really cheap to put together - especially as you'd need
just half of that bar for Remote Buddy. Best regards,
Felix

This posting is older than 6 months and can contain outdated information. Oh, it really depends on the strength of the IR source and whether it's standing still or changing its position randomly (like with the light of a candle). One light source works very well provided that it is strong enough. Two distants points don't add any advantage in precision or smoothness. They move by the same offset - and so does the mouse cursor in return. The "black corner" phenomen is actually what the calibration feature
in Remote Buddy is solving. With it, you can set the actual
"rectangle of sight" Remote Buddy should use to interpolate to your
screen's coordinates. Best regards,
Felix
