Title: Wii IR camera as standalone sensor
Post by: engineerzg on May 03, 2010, 11:56:55 PM
As subject. I have a ideal, the core part that we need in Wiimote is IR camera, right ? So can we just use that camera to work with smoothboard program? or we need more part? If we only need this camera, we can order it from nintendo with cheaper price and without loss any performance. Some pic about IR camera in Wiimote

One of the advantages of using the Wiimote is that the Wiimote's processor handles the image processing to track the IR points. If you are connecting to the IR camera directly, you will need to process the IR dots from the raw data from the IR camera. With this, you are actually not limited to use the Wiimote's camera but will need more processing power on the computer.

The Wiimote's IR camera is actually a PixArt camera with a IR bandpass filter.

If you would like to use Smoothboard, you will need the entire Wiimote as the connection is made via Bluetooth and the Wiimote will need to output the IR dot coordinates directly.

How much would a pixart camera cost, or is it even available as a separate unit? If you HAD to create a little camera box that just had the camera, image processor, bluetooth connection chips, a power connector and a little attractive case, how much money and time do you think we would be talking about?

I personally have nothing against the Wii mote but I know many possible sales are going to go bye bye because this "LOOKS" clunky / hacky.  If we could look like we had a unit that was built and designed to be a white board system from step one, I think we could get more sales and maybe even charge more.

What microprocessor / microcontroller is built into the Wii or was this custom designed by Nintendo?

Hi,

If you are able to design and manufacture a similar device, most probably it will cost a lot more. This is of course unless you are able to achieve economies of scale by selling hundreds of thousands.

However, as there as China-made Wiimote clones available in the market, it should be possible.

I guess if you are to design something similar, it may take a team of electronics and software engineers. This is of course separate from the manufacturing process which will cost a significant amount of cost as there will be circuit board printing, plastic molding, etc.

Like I have mentioned before, all the while there is always been optical based interactive whiteboard system available in the market. This will also would mean that there should be pre-existing patents covering this area too.
