accelerometer game BOING...

A New version of Boing is available on my website. This requires a device that has opengl es support.
Touch the screen or use arrow keys to start or pause the game.
Tilt the device side to side to move the ball.
Enter button exits the game.
When paused, touching the lower portion of the screen where it says resume will resume
and touching the upper area where it says exit will exit the game.
-------------
BOING... is a game built for use on a HTC windows mobile phone with a tilt sensor / accelerometer / g-sensor. Move the device to move the ball and bounce from platform to platform.
-older version instructions-
The phone I used to test development has a resolution of 240 x 320.
I have tried to add support for larger resolutions but am unable to test.
I have also tried to make it usable by phones without an accelerometer with the arrow keys.
Please visit my website http://flyingmonkeypuke.com/boing
It is playable but I am still having some trouble with consistent platform generation and collision detection.

any screens pleas ?

Hi, could you put some screenshots? Thanks

It's neat. Tested on a Fuze/Touch Pro and it works well. There's some slight flickering going on. Are you going to build in levels or something similar?
For anyone asking - there are 'trampolines' that a ball bounces off of and goes higher and you need to move the device left/right to move the ball around while it's in air and the platforms are spaced out randomly. I like the concept. MyMobiler won't pick it up on a screenshot...

Thanks for trying it out. I was curious how it plays on a vga resolution. The way I tried to support larger resolutions was to just add more platforms when a larger screen size was detected which probably adds more of a problem with the randomly generated platforms. Unless the ddraw is scaling to fit the vga screen which might be the cause of the flickering? It runs smooth and with no flicker on my device.
I am working on an opengl project at the moment. I will revisit this project and make some adjustments when I can.
I couldn't get MyMobiler to work to get a screen shot either so I just mocked one up.

Tested it to see how it behaved with cursor keys, but since I dont have accelarometer, it crashed...

hey twolf, I dusted off my mpx200 and made some adjustments. I got it to work but I don't recommend running this on on a device with 176x220 resolution. still no flickering on this phone either.
new zip uploaded to my website.

nop.... It shows "unable to load sensor dll", splashscreen appears, crash.
I have a Qvga (240x320) screen.

Doesn't work on my Touch HD (480x800) I see for one second the title, and then it closes..

Has anyone had a positive experience with this program? I would appreciate any feedback.
If anyone is interested I posted an opengl cube that responds to tilting the device.

I had a good experience but I stated that already I didn't see the 'cube' post - I'd test it out...anyone making gsen apps is good in my book

It doesn't work on WM6.5

And with WVGAFix3 resolution to 640x480? It should work i think.

doesn't work with touch pro 2

Doenst work on my Touch HD either. It also doesnt work, if i use WVGAFIX3

New openGL es build of Boing now available. hopefully this will work better for everyone. I finally got access to a touch pro to test on. no sound in this build. enjoy

Thanks a lot, looks great!
Hope soon we can have it with sound

Works fine on VGA screen (Diamond). Thank you, nice game

Works great on the HD2. Very addictive game indeed!
The only problem is that touching the screen pauses and then resumes. The menu doesn't do anything for me, so I can't exit the game that way.
Other than that, tip-top mate

when paused, touching the lower portion of the screen where it says resume will resume and touching the upper area where it says exit will exit the game.

looks alot like the old leaked pics..

at least it looks like there's speakers at either end of it and not a paltry one like on the X1

Looks a bit fat. Speakers on both sliding parts seem like a waste.

The speakers aren't at the top and bottom of the phone [in portrait mode]. They are on the two back slits of the phone. The speaker grille design is aesthetic. I've seen phones with fake windows mobile speaker grilles... and they are usually Samsung, but my wish will come true if I am wrong about the X1.

I am in love with both the X2 and Rachael,
the X1 is the beginning and im glad to be a part of that now I want the next chapter, something inside knows that SE is going to kick some ass with the next gen of xperias and i cant wait to see how this story pans out.
come on SE show us what u can REALLY do. Damn they are going to be good.

The blue prints look alot nicer than the real thing.
My only wish is to changed the top row into number keys and add FN CTRL Indicators.

my WISH is to get a tiny cell wtf, the x1 so thick and heavy!
the best keyboard is on the touch pro2, if only the were a jack 3.5mm and material buttons like the x1, htc wouldhavedone thebest cell ever, i'mnot talking even about the xperia panel which are so ridiculous....
however I think x1 has inovations like the opticalmouse very useful to surf the web AND the PAD(which seems to have disapered on the X2...), the camera which was the best when it came out. that's it.
speaker is crappy, my cell cracked (I had to send it twice to get repaired)
don't think I am against the x1 but we must admit that it is not so GREAT

I would rather have a keyboard cursor arrows than a D-pad that is hard to press. And the X2 delivers that. Besides, the main reason for a D-pad on the for me is that it allows me to move among the text and edit them but the buttons are too thin on X1 and optical mouse either goes too fast or too slow. And even worst no one realizes that D-pad is used more often on the text field then on menu navigation. By doing this, the arrow keys on the X2 is perfect text editing.
Haven't you realized that most of the time the X2's optical-joystick-only-feature is perfect for menu navigation especially when the phone is closed you usually don't type anything. And when the phone is open: there you have it, cursor keys that work exactly like a D-pad but even better than the X1's optical joystick. Why do people think the X2's optical joystick is a bad design?

D-pad + optical joystick = Win. Anything else is a big ass failure in my book.... Why downgrade it when you have the perfect setup as it is?

i dont believe that "thing" is the next Xperia.
why would they build something so ugly after they made an amazing phone like the X1 !?
& everyone knows that SE cares so much about the style even the cheapest phones they got look good!
i think the leaked pix & the blue prints belong to the X1 , as they made that ugly ass phone & made it better.

Axis-inversion bug with multi-touch?

I've read most HTC multi-touch handsets use a bugged controller that has an axis-inversion issue. You can test this yourself on all Android handsets by downloading the Multitouch Visible Test (Battery Powered Games) application from the Android Market. The Motorola Droid doesn't have this problem, so I've read.
For example, my HTC Magic (32A) will show this axis-inversion problem after performing a diagonal pinch gesture and then pulling my fingers apart again (while still contacting the screen), although it can take several pinches to demonstrate it. The phone will usually correctly detect the position of my fingers when I pinch, but when parting my fingers again the phone will believe my fingers are retreating to the wrong corners of my screen.
Can someone with an HTC Legend please test the screen with this application for me? Cheers!

Hi,
I just tested, and yes it is like on Magic, he inversed multitouch in few seconds, but then he is back on track.
So it is a HTC bug.

Thanks. If this device ever becomes available in Australia I think I will still consider getting one.
While the bug is still there, I don't think very many (if any) multi-touch gestures care too much about exactly where your fingers are. For the pinch gesture, it really only matters where your fingers are in relation to each other.
It sucks that there's a bug, but there's nothing we can do about it. And it's really a very nice phone in every other aspect.

Well, I didnt find this bad, and I am using it big time, internet, photos and stuff , so bug can be bug, but it is not bugging me

Here is a picture which I take for review of pinch to zoom:

No, there are no bugs in a Legend.

Multitouch is as brilliant as it is easy. When 2 points on a touch screen are pressed. You get 2 X and 2 Y coordinates. Problem is, it is impossible to know where the actual fingers are at this point. There are 4 options for each finger (2 x and 2 y combined)
As you can see in this example, the light blue dots are your fingers. The dark blue dots are the other options for the software to consider. The lines illustrate what x and y range the software will get to determine where the fingers actually are.
Luckily, it is very rare for people to put their fingers on the screen at the exact same moment. Which gives the software a hint for where your fingers actually are.
And for most gestures (like pinching) it doesn`t matter where the fingers are.
This the type of capacitive touchscreen that is used by HTC. Apple however has a far more advanced type of touchscreen that uses more sensors then just x & y. The touchpad of a MBP can detect up to 11 fingers and still is very accurate. How many the iPhone can detect I'm not sure, but it certainly uses a more advanced touchscreen then HTC Android devices.

[Q] see this touch screen behavior? Co-linear touch points cause lost of location

Has anyone used the multi touch app to test their touch screen? It looks like this picture. The program projects a vertical and horizontal line across the screen where your finger is. I've noticed that with two fingers, sometimes one of the finger points "disappear" from the screen when it lines up with the other finger - that is, when the horizontal lines from the two points line up.
This happens sometimes when using two fingers, and all the time when using 3 or 4 fingers and making the horizontal lines of all 4 fingers to line up. Since the program uses pure sensor data, without much manipulation from the OS, I think this means the capacitive grid is actually losing the touch location (not seeing the finger that disappears).
I was wondering if it's only on my unit or if anyone else sees that?
I've tested with my finger far apart and close together when lining up the cross hair lines. The disappearing finger location isn't caused by the fingers being too close. It's definitely disappears when the lines fall on the same "grid" line. It happens on the horizontal as well as vertical grid lines.
Thanks.
Here's the app:

I cannot replicate this behaviour either horizontally or vertically either in your suggested app, or another similar app by jpjoyjp called Multitouch Test. In either case, aligning two or more fingers from either hand on the exact same horizontal or vertical grid line doesn't cause any touch points to stop registering.
For reference, I'm on a 32GB stock Transformer with 3.1 US installed.

Using Yet another MultiTouch tester I can't duplicate that behaviour.
It tracks all ten of my fingers splendidly well and I can't get them close enough to make them confused - well, I get confused though and often lift my fingers from the surface when trying to get close

Works fine here. Btw, the limit seems to be 10 fingers. Had to ask someone to help me with experiment. xD

Wait I think I see what you mean now. When you hold one finger and quickly tap with the second one, it doesn't detect that the second finger is not longer there. The key is to hold first finger in the exact same coordinates.
Hehe or not.. I didn't read your description carefully.

Thanks for trying it everyone. Well, I tried again just now, but couldn't reproduce it. Weird. Don't know...seems ok now.

[Q] Nook Touch and Stylus ?

Hi there !
This is my first post. I've been reading XDA extensively on many topics, so first, thanks for all the information here !
I think I'm about to go for a Nook Touch.
Just a little question : I've seen on Amzn a stylus for the Nook Touch, but haven't been able to find any reviews of it. Does any one has any experience of that ?
I might find use of that to anotate PDFs...
Thanks a lot !

Since the Nook Touch has an IR-based touch screen, I've been led to believe that any stylus should work with it. However, I have an old Palm stylus, and it DOES NOT work with my Nook Touch. It seems that the tip of the stylus is too small to make the touch screen react. If I use the other end of the stylus (it's much thicker), it works about half the time.
I don't know if this is a hardware limitation or not. It would be great if there were a config setting somewhere to make the touch screen react to smaller objects, like the tip of a stylus.

Thanks a lot !
I found it quite strange that we can supposedly buy stylus, but no other site mention it.
If you make any other experiment with the nook (since I haven't buy it yet), I'll be glat to know
Thanks again.

I've been experimenting with this a bit.
Even thick objects are unreliable if the point of contact is too small. For hard materials, round is too pointy. Something soft is required to get enough coverage.
I've had good luck with an ordinary round-point #10 paintbrush (about as thick as a pencil). A cotton swab and an earplug-on-a-stick also work, but the brush feels better.
I'd also expect a soft-ended stylus designed for capacitive screens to work. Anything designed for resistive screens is probably too thin or pointy.
I'm curious about the spacing and positioning of the IR sensors. I tried looking at the bezel with a couple cameras in the dark, but they didn't pick anything up. Either it's too dim, too narrowly focused, or my camera's IR filters are too effective. I wouldn't expect them to be very bright, just based on the battery life.
I've also experimented with hands-free page turning, by blowing some kind of little flag to flap against the screen, but I haven't come up with anything reliable yet.

What would you say could be the use of such stylus ?
Is it possible, for example, to annotate more precisely than by hand ? Is it possible to write ?

I mostly use it for page turning.
For example, suppose you are reading while you eat. You've got a plate of food in front of you, and beyond the food you've got your nook propped up in a little picture-stand.
With a stylus it's easy to turn the page without reaching across the table and getting greasy fingerprints all over the nook.
I haven't rooted my nook yet, and it doesn't seem like much of the built-in functionality would benefit from a stylus. For example, notes are just typed on a keyboard, not freehand.
Rooted, there are probably apps that would take more advantage of it, but I wouldn't know.

Stylus? I use simple watercolor brush with NST

Also for turning pages?
Could you write with it? (annotate PDFs, for example) Or draw? (OK, paint, in your case )
