AFAIK Natal was based on a previous system from MS that relied entirely on visual recognition. Of course it was really fucking expensive so maybe they went IR with Natal since now everything has distance sensors, even my vacuum cleaner. Anyways, about MOVE messing your "atmosphere", well using the wand thing as a flashlight and the other as a gun would kick ass in games like Doom3 or Alan Wake, and it could even flash red or blue when some ugly shit is about to happen, like Frodo's sword when orks were about to rape him.
I don't think anything has shown the move light ball to be all that bright. As well if you're going to play in a dark environment I'm sure they can town down the light/color since in a dark room the PS Eye won't have to work as hard to pick out the ball from the image.
um...unless the PSeye can do proper IR optometry the room's darkness will adversely affect the sensor if the lights are dim.
Not really, if anything it will work better. When you calibrate the Wiimote's and you see the Wiimote camera-eye-view the only thing it can see is the sensor bar. The same thing will apply to the Move. It only just needs to see the glow for it to work. Anything in the background will just be a distraction. Apparently the colour changes depending on the backlighting in your room (incandescent, flourescent, etc) which is actually pretty cool when you think about it.
Well the whole reason why they're using a color spectrum is because the Eye isn't capable of infrared, unlike the infrared receivers located on top of each wii remote. Sony's balls might be fancy but they're not as robust a solution as nintendo's when it comes to pin-pointing stuff. I'll give them the scaling though, the ball allows better relativity as a focal point vis-a-vis the Eye.
If it's that robust, how come it still works like shit though? If we are nit picking for the sake of it, the Wiimote really isn't that accurate, hence motion+ which doesn't rely on the sensor bar.
PSEye + Move requires light, yes. "Fortunately", the controller itself seems to generate whatever light it needs. But using it in the dark would certainly be a slight rave stick experience. You can do it, but you'll also have a glowing ping pong ball (or two... or eight) floating around in front of your face in a wide (distracting?) variety of colors. What I am curious about is how well the PS Eye is capable of differing between an actual controller and a different light generating object (nothing a color change on the controller shouldn't change or the motion input from the controller itself should be able to handle via a quick "did this move?" check.) Relying on the sensor bar is, again, entirely a design choice. You can do motion tracking, albeit a tad bit limited, without the use of the IR camera and the sensor bar, relying entirely on the tilt sensors in the Wii remote. There are plenty of games that do this. In fact, the majority of software that doesn't have a direct pointer on the screen does it this way and some games that do feature a pointer only feature it briefly to calibrate the tilt sensors pre-game start. What the Motion+ does is merely add another layer of sensors for more accurate motion tracking. Whether or not that additional data is used along with the IR camera + sensor bar is entirely up to the individual developer to decide.
keep in mind that the accuracy of the Wii Remote is not the issue here, it's the clarity and consistency of the optical signal. Practically this means less error correction and need to compensate, since the basic idea (Infrared) is one that covers most areas pretty well.
The frequency of the light doesn't make any difference to the device, otherwise in the daytime, you know when the sun is pumping out all that IR light the Wiimote wouldn't work. They just use IR as it's less obtrusive to the end user. Something Sony can't really do without forcing you to buy another camera just for IR. I already have 2 PSEye's, I don't want another.
well what do u know..it doesnt! daylight really screws with the IR sensor on the Wii if it's anything that catches its attention.
I have to agree on that daylight thing with the Wii remote. The Wii remotes work perfectrly fine in pitch black or bright shinning sun. I'm now a 360 gamer but had good fun with my Wii when I had one. Never ever had a problem with the remote not being reconized. yakumo
http://www.nintendo.com/consumer/systems/wii/en_na/settingsSensorBar.jsp Sony won't have THIS^ problem, but they have a more dynamic range of sensors (ie colours) instead of a single infrared light, which puts the probability rate of error quite high if not handled correctly.
Depends what res the PS3 camera is put into (it has a 120hz mode but at a low res) and the fact the system controls the color of the ball lets it adjust the colors to something it finds to have less troubles with. It will be able to self correct it self during calibration.
The Move has motion sensors which help calibration. It's eyetoy visual tracking and motion detection via blue tooth.
