Hello everyone, Lightpack project here. We've got some spare
time today, which will be well spent on a demo for you. First of all, the open beta
of Prismatik's Android app, anticipated since June, launches tomorrow. Behind my back there's
a 32" Samsung TV with 2 Lightpacks on it. There are 12 LED modules overall, more isn't
possible to go in this setup. Ouya is connected to TV and controlled with
gamepad. Lighting works well, and i'm going to demonstrate it to you.
As you might noticed, lighting corresponds also to the OUYA interface. Let's have a look
at Prismatik. GUI is based on the Unity engine. We did our
best to make the interface as simple as possible. There are 3 lighting modes buttons on the
main screen. Below the buttons there's an information block, which shows how many Lightpacks
were detected by Prismatik and if the root privileges are granted.
The first mode, Solid color, is a typical but slightly simplified color picker, where
you can choose any color to your liking and play with saturation channels and lightness.
This downbar can be minimized. Lets have a look at the second mode, which
is the Mood Lamp. There are four kinds of common animations available in this mode,
speed of each can be changed. So, with "Simple" animation on, lighting randomly changes colors
with the set speed of color change trigger. There are also "Water", "Lava" and our old-timer
"Cylon". These animations can be changed, which depends on community and your feedback.
And the most interesting mode of all is the image capturing mode, of course.
There are not many options available, we've cut off all irrelevant stuff in order to make
controlling as easy as possible. Here's the FPS limit control bar. FPS slightly affects
the OS performance, and we're actually planning to cut this option off too. The default value
is set to 30. Another option here, called Threshold in desktop
Prismatik, is a Magic eye-saving feature (we failed to come up with some other name for
it). I strongly recommend turning this feature on to everyone, it's just a must-have for
lighting. There will be more details about it along the video.
The last option here is an average color lighting: all LEDs give out one color, which means that
all sides of your TV are lighted with the same color. Well, we shouldn't apply this
option now, as this is a demo video of performance capabilities, so lets turn it off.
Certainly, the question is how user-friendly is the setting and tuning. Here's the zone
adjustments screen. Everything is pretty simple here, even though it might seem complicated
at first sight. Obviously, all these bubbles represent capturing zones, which you have
to adjust once at the initial setting according to your LED modules location. Each bubble
can be selected and dragged around. You can also switch between bubbles. We've got central
zones inactive due to the reason I've mentioned before — there are only 12 LED modules for
2 Lightpacks here because more than that cannot fit to such small TV. Those of you who already
got their devices from our first shipment won't be surprised to hear of Constellation
system we came up with, all Constellations are in the Quick-install Guide. So if you
followed the Constellation pattern while mounting your Lightpack, then you only have to push
the corresponding button here and your setting is complete. This is what we call a one-click
setting. I'm not going to save the current setting, lets go back to the menu and return
as there's still plenty to show you on this screen. Certainly, there's a Help section
(overlay) with control buttons explanation. By the way, I got to point out that GUI is
optimized for gamepad controlling. We've tested it with different gamepads and mostly it performed
very well. Of course, GUI will still shine even if you are using a mouse or a keyboard
or a touch-interface. There's also a test video, added for checking
the correctness of your setting, which allows to spot a misplaced zones .
There's nothing unusual left here, so another option that is worth to show is the White
balance. As you see, it's also pretty typical. Overall, the app is very simple, nothing complicated.
Lighting can be turned off by pressing the screen capturing button.
Now lets see the real-life performance. Android's special is that capturing works
absolutely everywhere, be it a game, a video or anything else.
Lets take a look at a game. Not sure which would be better to show you. All android games
on OUYA are pretty colorful.
Now let me show you the Magic eye-saving feature in action by the example of this game, Mirror Moon.
The "left-screwing" game, as Tim calls it. Lets see what happens here and how it works.
Magic eye-saving feature is an utterly cool story. It enables lighting when the screen
is black, like now. As you see, we are walking on some red planet, and lighting at the bottom
is red. And at the sides and at the top, the lighting isn't off but transmitting a faint
glow, a faint average color, i.e. a faint red color. This actually looks pretty cool,
and this is how the lighting should work always. I won't stick to this game, there's not much
time for that. I think I've covered the basics. Now I'll
show you the capturing in a video. Of course, lighting works on XBMC with all
kind of OS screens, as it was mentioned before. There was a Vimeo app for OUYA presented recently,
lets have a look at something in it. For example, this one.
I want to tell you right away that we implemented automatic letterbox detection in Prismatik.
I.e., if the video got black stripes at the top at the bottom or at the right and at the
left, this stripes will be automatically detected and only the video image will be captured.
It's a long-awaited and highly requested feature by you, so we fulfilled your wish.
Your feedback is extremely appreciated. It would be great if you download .apk, test it
and give us your review on its performance: what features work and what don't. As unfortunately,
we only could test it on OUYA, chinese HDMI sticks and Xios, Android-based media center
by Pivos. I leave you to enjoy the video now and bid
my farewell. Till next time!
