Thread: Details on Sensor Bar LED configuration Hi there, I'm making a currently setting up my Wii with a projector. I'll be putting the Wii next to the projector (which is mounted to the ceiling) and therefore will make my own sensor bar to put under the screen. Making the sensor bar is the easy bit. What I'm wondering is: is there an optimal distance of the IR LEDs? I'm pretty sure Nintendo simply chose a distance which matches most TV sets. So, for a 200cm image diagonal, I'd probably chose a larger distance--or is this BS? Does anyone know any details about the triangulation algorithm used? Or can give me advice on what distance to chose?http://forum.wiibrew.org/read.php?7,64803,64803#msg-64803Sat, 06 Jun 2026 00:03:20 +0200 Phorum 5.2.23 http://forum.wiibrew.org/read.php?7,64803,65432#msg-65432 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,65432#msg-65432spritesmods.com]
Seems to make much more sense with a projector :-)]]> Daid HardwareThu, 24 Mar 2011 16:15:55 +0100 http://forum.wiibrew.org/read.php?7,64803,65392#msg-65392 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,65392#msg-65392 uglymonkey HardwareSun, 20 Mar 2011 23:31:26 +0100 http://forum.wiibrew.org/read.php?7,64803,64940#msg-64940 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,64940#msg-64940 Daid HardwareFri, 25 Feb 2011 14:16:05 +0100 http://forum.wiibrew.org/read.php?7,64803,64914#msg-64914 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,64914#msg-64914distinct points of light.]]> tueidj HardwareThu, 24 Feb 2011 20:35:38 +0100 http://forum.wiibrew.org/read.php?7,64803,64906#msg-64906 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,64906#msg-64906

this is an impossible question to answer. you really need to factor in the distance between the LED and the wiimote.


i have a 32" TV and the stock wii sensor bar. it works good for playing 10ft from the TV. but playing 20ft from the TVis impossible. the wiimote cannot track correctly and the pointer constantly disappears. i got an adjustable sensor bar that moves the LEDs from the stock width to 6 inches wider. now my wiimotes work fine 20ft away from the TV.

the TV is the same size, but the distance between the LEDs is different. without factoring in the distance you will be playing from the LED source, you cant generate a ratio from this.
Which has nothing to do with the distance between the LEDs, and all with the brightness. I think the default sensor bar contains 2 leds per side. If you boost that to 4 LEDs you get a much better distance.]]> Daid HardwareThu, 24 Feb 2011 17:54:04 +0100 http://forum.wiibrew.org/read.php?7,64803,64886#msg-64886 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,64886#msg-64886

thanks for that input. I don't have Wii Play, so I haven't tried this. This is a good point, though: If my assumptions are correct, gauging the z-distance would scale linearly with the LED distance, meaning I'd have to move the whole thing more than twice as far in z-direction, which would be a bugger.
Are there any other games that use z-distance information?]]> brownieman HardwareMon, 21 Feb 2011 11:38:21 +0100 http://forum.wiibrew.org/read.php?7,64803,64850#msg-64850 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,64850#msg-64850 tueidj HardwareMon, 21 Feb 2011 02:21:38 +0100 http://forum.wiibrew.org/read.php?7,64803,64835#msg-64835 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,64835#msg-64835With my projector, I have an image width of a bit more than 150cm. My IR sources (for figuring out the distance, I used candles) are about 52cm apart to give the right response--if I use the original bar, I basically have to point right at the IR sources.

I'm pretty sure the Wii-Remote simply uses the two IR sources to figure out the bottom line (or top line) of the screen and assumes the LEDs are placed at about a half distance of the total screen width, centered around the middle.]]> brownieman HardwareSun, 20 Feb 2011 16:07:48 +0100 http://forum.wiibrew.org/read.php?7,64803,64805#msg-64805 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,64805#msg-64805 tueidj HardwareFri, 18 Feb 2011 12:12:44 +0100 http://forum.wiibrew.org/read.php?7,64803,64804#msg-64804 Re: Thread: Details on Sensor Bar LED configurationhttp://forum.wiibrew.org/read.php?7,64803,64804#msg-64804screen.
