liqbase cool inverse Augmented Reality

[sultan111000]

very nice

[lcukmaemo]

@zbo7800 CONGRATULATIONS!

Yes, thats exactly it :)

I have uploaded a slightly altered test version of package to maemo extras-devel, its called "invar" and works based on green lights.

if you have 2 N900s, you can test it yourself and play around.

its just an image viewer but if you tile 9 of them together they will collaboratively show the big picture :)

the app on the phone has an overlay that covers a large area, just like the paper you wrote on. we are only seeing a small window of that area, the paper serves as a map to the area. it is difficult to tell from the video if that overlay is separate from the apps being shown and if the apps are being "snapped" into place when the edges of the screen are within proximity, or if it simply a large app. 

[LikeNoOthr666]

The only thing I would say that it is, is the front facing camera. Its probably looking towards something that is actually above the phone and paper, thus, the paper that you see is not gonna be needed.

[GenericBlack]

phone has sensors(gps, accelerometer, all that stuff) so it can tell which way you move the phone and by how much, when u open the app it probably starts from the middle panel and maps itself out, so now which ever directon u move it, it goes to the corresponding screen

[lcukmaemo]

@GenericBlack that is incredibly detailed and also incorrect.

[zaffe93]

it's a video lulz

[j9kl]

its a video on your phone

[lcukmaemo]

@j9kl

heh, nope! 

[MisbehavingMal]

These comments are full of people who've never used an optical mouse. I find that hilarious.

[lcukmaemo]

@MisbehavingMal i find your comment hilarious also ;)

[ItsMeRobin10]

its kewl, but too bad its a shitty nokia phone

[lcukmaemo]

@tehhez

no.

[lievelake]

If this was on iPhone, I would have guessed it's "magic". But since it is not, I would have to guess it has something to do with the camera focusing sensor (not the camera it self) and line crossing.

[lcukmaemo]

@lievelake it works the same without any paper there.

i just drew those for my benefit

[4guns]

is the front facing camera sensing direction by using the captured images and looking for best match on neighboring pixels?

[burgwinkel]

You've ruled out accelerometer, so front-facing camera then.

[Abemelekm]

accelerometer tracking?

[JookieJenkins]

@Abemelekm I think that's what it is. He mentions in one of his comments that it works the same without the paper. It's gotta be the accelerometer.

[collegavanjevader]

front camera with head tracking?

[lcukmaemo]

@collegavanjevader closest yet :) it could operate based on head location, someone mentioned such a thing the other day whilst I was discussing it.

[VWdriver]

its the camera...

[dEM0nsTAr]

@VWdriver Are you sure that the camera can "see" something with nearly no light and a few mm distance?

[lcukmaemo]

@dEM0nsTAr

thats right, there is no way for me to focus on the paper (I tried)

[dEM0nsTAr]

@lcukmaemo so, what is it then? The full Maemo power unleashed?

[lcukmaemo]

@dEM0nsTAr haha

[VWdriver]

@dEM0nsTAr All it has to see is the lines drawn on the page. Note the delayed response traveling from frame to frame, it has to see the lines before it knows which frame to display. The LED flash can be on to allow the camera to see the lines.

[maxximuscool]

haha magnet? :P

[lcukmaemo]

@maxximuscool nahh dude. #liqbase #voodoo

[lcukmaemo]

nope BrEn, accelerometer is disabled during this test

(as shown by the inactive cell in centre top)

people on twitter are saying its witchcraft.

[BrEnNo1023]

my guess is that it uses accelerometer and distance to work out which apps to select. and maybe a parameter to remember the position of each app...thats just fantastic, we need to work on apps like this to win over the plain old iPhail!

[Fila718]

what is the name of that app?

[BrEnNo1023]

@Fila718 are you serious? dude it's right there in the title AND in the description.
