But this basically confirms that the IR camera has pointer functionality.  So that's something.

 

Not really - they were replying to a comment asking about a 'motion pointer', and it's easy to imagine one working purely gyroscopically (as with the gyroscopic text entry on PS4, for example). The tweet doesn't really tell us what technology is being used. Or, you know, if it'll actually be much cop as a control method.

Motion pointing needs a point of reference.  My previous explanation mentioned the point of reference being the dock's and tv's positions relative to where the joycon is in 3D space.  But people didn't seem to like that idea.

 

It's a simple concept that only requires you to point at where your TV is to calibrate, though.

 

The gyro and distance measuring (and the fact that gyro can tell when its parallel to the ground or not), should be able to recall where it is in 3D space very accurately.  So it should be able to remember previous positions, as well.  So I was thinking, every time you detach the joycons, it recalls where it was in docked position in that 3D space,  and where it is now with you holding it.  So it can recall the dock position automatically, based on where it once was.

 

The only information you have to input is the TV's position, since it can't know this.  Do so by pointing at the television with the IR, and it should be able to remember where the TV and dock are in relative space.  This won't be real time, just a map created essentially of these locations, that it can recall for positioning, depending on where you go with the joycons. 

 

As long as the dock and TV remain in the same place, you shouldn't have to recalibrate, as it could constantly be measuring where it is in 3D space, and by extension where it thinks those two objects were based on the map it created.  And from then on you can hold the joycon the correct way, and the IR no longer needs to be front-facing to guess where the objects are.

 

If you were to move your dock to another side, it would still think your dock is in its original position, and that your TV relative to that location was as well.  And it would mess up calibration.  So you'd have to put the right joycon back in the dock, then detach it, so it knows where the dock is again.. then you'd have to point at your television again to know their object relatively in 3D space.

 

But basically it just acts like a sensor bar, by guessing the locations of the TV and dock, based on where they were when the information was gathered, relative to where the joycon is now.

Or we can go with my original guess, that you hold the damn thing upside down and the tablet has a built in sensor bar. :lol:

Oh boy he's done it again.

 

I think it'll work more like a mouse which has zero idea where the TV is.   Maybe there'll be a calibrate button you can press when pointing at the screen.

 

One of the mini-games in 1-2 Switch has the the player turning the Joycon on a table top which means it has a compass* (wiimote didn't have this).   So pointing at the screen and pressing a calibrate button would probably allow it to centre the orientation on the yaw (x) and pitch (y) axiis.      

*Or just REALLY good motion sensing I guess.

I just think recalling two points of reference is better, since it shouldn't have to calibrate but only once, so long as those two points remain in similar positions to each other.  So I was assuming Nintendo would do this instead so people didn't have to constantly calibrate their controller anymore.

 

But doing what you're saying, they'd still have to recalibrate all the time... and that can be tedious.  I simply think with all the technology they packed into this thing, they've found a better way.

Yeah having an anchor point is better but not essential.  I don't there's anything for the IR camera to latch on to.

 

I think the motion gyro stuff is much improved and drifting will be much reduced.  It'll still be there but not a big deal.   While the pointer function on Wii was direct a mouse is mostly relative (you see the cursor and work from that rather than point) and that works fine.

Except that I can't use a mouse when I'm facing backwards, like I can a joycon.  It will be difficult to distinguish particular angles in this way without an anchor point.  A mouse deals with a flat surface, not 3D space.

 

But I guess it doesn't matter.. I'm just happy motion pointing will be a thing that is possible.  Hopefully Wii emulation will happen.

Didn't they mention that the joycons can tell the positions of one another, relative to their own?  Maybe they can tell the position of the tablet as well, perhaps it has similar gyro sensors? The screen would need gyro anyway, considering they planned to eventually do VR.  So it probably has built in sensors.

 

Then you just input in settings whether the dock is left, right or center to the television. And whether or not it's facing forward or sideways.  Then input your TV's size.

 

Should give it a general idea of where your TV is and how big of a space it uses, right?  That's the missing point of reference.
