That is something I didn't notice at first glance. HTML5 isn't my first 
choice, and offline capability is a must.

It does seem very well featured, and may do more than I need.  

It's also pricey at $5490 per app. The ideas I had in mind may not bring a 
big ROI at that cost. But I'll look at it some more. Thanks.

Thanks. I might try it if I were going the computer vision route.

There isn't a lack of options - just looking for feedback on which ones
actually work.
The largest list I could find on this topic is this:

http://socialcompare.com/en/comparison/augmented-reality-sdks

I probably need:

  * GPS and sensors use
  * Placement of markers, icons, and some vectors (lines or shapes) in
the 3D world.
  * Should work without internet or data. Shouldn't be a problem since I
am not counting on an online feed.
  * Non GPL.

I may need ( in the dream future):

  * more complex 3d rendering with meshes and dynamically loaded
textures. Nothing too major, just maybe like overlaying a Google
Earth like image with the camera. ;)

I probably don't need:

  * Data for the Points of Interest, I'll provide my own and they'll be
small in number.
  * Computer Vision based reality. That eliminates quite a few.
  * Object manipulation - I don't need to design cities or anything like
that.

I'm looking for more of the viewfinder sort of thing.

I prefer buy over build, I think because I don't want to start from
scratch on working around the bugs on every single device. Of course, I
don't want to buy and still have to fix all the bugs myself.

So here are some I'm considering.

  * ARLab.com. As described on their website at least, it sounds like
the ArBrowser


don't know anything about this, can't comment on it


  * Wikitude. A bit more expensive, but possibly more established and
mature. Since their sample app has a million downloads.


this one sucks in my opinion.
It use a webview for an HTML5 app.
HTML5 app sucks for many reasons. Performance is one of them.
I would stay away from it.


  * http://www.chupamobile.com/products/details/296/Augmented+Reality+Toolkit/.
Probably made by a guy in his basement, but if it does work, it is
only $20. Probably worth buying just to prototype something before
going full scale.


As for ARLab, don't know, can't comment

Reading seems like Metaio http://www.metaio.com/ is the most complete 
(cross platform) Augmented Reality framework.
But you can't develop for it on Linux which makes no sense at all in my 
opinion.



In my company we use Vuforia 
http://www.qualcomm.com/solutions/augmented-reality for natural features 
and markers tracking.

It's unbelievably fast and reliable.
We haven't much experience with it on Android yet (we are starting now 
on the platform) - but I personally tried the examples and it works 
pretty well, fail to run only on very old devices or low end devices, I 
also tried with a RAZR with x86 processor and it works... MIPS devices 
will not work.
it doesn't provide a 3D engine tough (see my other post in this ml) so 
you'll have to find one on your own.

[android-developers] augmented reality

[tsioularisa]

Hello i have to make an android app for my thesis!the subject of the app 
depends on augmented reality!The brief description is that the app uses 
your position(gps) and your camera. it then detects some places of interest 
and when you click on them it gives you extra information about them. I 
want to ask you if you suggest any augmented reality development kit/sdk.

Thanks in advance and sorry for my English mistakes.

[android-developers] Augmented Reality Implementation

[Jeffrey Hodes]

I'm trying to implement a simple augmented reality tool for Android. All it 
needs to do is take as input my location and device orientation and the 
location of another device and present a camera view with an icon overlaid 
in the appropriate place in an appropriate size.

I'm stuck in two places:

I wrote code to get updates for the current azimuth, pitch, and roll of the 
device. The code looks like this:

private final SensorEventListener goodListener = new SensorEventListener() {
private float[] magneticValues;
private float[] accelerometerValues;

public void onAccuracyChanged(Sensor sensor, int accuracy) {
}

public void onSensorChanged(SensorEvent event) {
switch (event.sensor.getType()) {
case Sensor.TYPE_MAGNETIC_FIELD:
magneticValues = event.values.clone();
break;
case Sensor.TYPE_ACCELEROMETER:
accelerometerValues = event.values.clone();
break;
}

if (magneticValues != null && accelerometerValues != null) {
float[] outR = new float[9];
float[] orientationValues = new float[3];

SensorManager.getRotationMatrix(outR, null,
accelerometerValues, magneticValues);
SensorManager.getOrientation(outR, orientationValues);

double azimuth = Math.toDegrees(orientationValues[0]);
double pitch = Math.toDegrees(orientationValues[1]);
double roll = Math.toDegrees(orientationValues[2]);

}
}

When I use logging to read these values, they seem relatively stable, but 
they do not seem to correspond to angles around any natural set of axes, 
and I can't figure out what the numbers represent. How should I interpret 
these numbers?

The tutorial at http://www.devx.com/wireless/Article/42482/0/page/3 takes a 
much simpler approach, but I cannot get it to work.

Once I have my device's azimuth, pitch, and roll, along with my latitude 
and longitude and that of the other device, how can I determine where to 
put the icon on the screen? This seems to be a complicated geometry problem 
where we must imagine the view field of the camera as an infinite cone, 
project it onto the surface of the earth, and see if the other location is 
inside the projected area, but this seems awfully complicated. Is there a 
better way that I'm overlooking?
Thanks!

- Jeff

Re: [android-developers] Augmented Reality

[Raghav Sood]

Currently, there are no books on Augmented Reality and Android, AFAIK. I am
in the process of writing one, but that will not be published until May.
You can see if it can help you: http://www.apress.com/9781430239451. If you
use Google, you should be able to find Chris Haseman's tutorial on the
subject on devx. That should serve as an introduction.

I'd also recommend looking into Augmented Reality engines like AndAR.

Re: [android-developers] Augmented Reality

[Ricardo Santos]

You will need more than 7 days for that...

My advice it for you to go beyond wikipedia and see some real image
processing books. I had this on college a few years ago and do not remember
the name of the subject, but I know that with some real research you can do
it.

Hope you don't have a deadline to this project... :D

This is currently not possible. Unless you are willing to write code that

looks from every angle, then I'd suggest you drop it.

This is limitation is barrier for my app.I want to detect Physical

black square paper then marker generator generate pattern and AndAR
detect bulb with background black square,But if i remove background

[android-developers] Augmented Reality Advertisement: Survey

[EdwardComb]

Hi,

As for completing the final year project, I am in the midst of
distributing the survey questions that are related to the enhancement
of physical advertisement like newspaper, magazine, brochure and
flyer. I believed, most of the people used to buy or read one of them.
Thus, I would really appreciate if you are willing to participate in
this survey.

About the survey:
This survey is looking for the responses of the people towards the
advertisement in the newspaper, magazine, brochure or flyer.
Specifically, it is referring to the food advertisement like
chocolate, ice cream, fast food and the others.  By using technology,
this advertisement can be enhanced and the responses from this survey
will be used to implement Augmented Reality Advertisement on Android
(ReADroid).

Your participation in this research is voluntary and completion of the
survey is an indication of your informed consent to participate. You
are under no obligation to participate in the study. You can decide to
withdraw at any point prior to, or during the study. If you decide to
withdraw, any information that has already been provided in the survey
will not be used.

If you agree to participate, please complete the questionnaires below:

[android-developers] Augmented reality: using camera feed as texture

[Nickw]

Hi,

Posted on this a while back but I've been doing some more work on it
since. The aim of the augmented reality app I'm developing is to
overlay geographical data (roads, hiking trails) on a camera feed for
navigation. Following other examples on the web, I've decided to use
the raw camera feed as an OpenGL texture and overlay geographic data
on top of the texture within a GLSurfaceView. The feed will be black
and white for the moment.

Only problem is, it seems to be impossible to capture camera data
without creating a SurfaceView to show the preview. However, since
you're not supposed to layer SurfaceViews on top of each other, this
appears to mean that I presumably have to create an invisible
SurfaceView just to be able to capture camera data. The other
solutions to this I've seen on the web (nhenze.net and AndAR) seem to
layer SurfaceViews on top of each other.

Is it therefore true that (prior to Android 3.0) there is simply no
elegant solution to the problem? The only solutions people have come
up with are either:
a) overlay two surfaceviews on top of each other (not guaranteed to
work);
b) create a "dummy" SurfaceView for the preview just to get
PreviewCallback working; or
c) reimplement GLSurfaceView from scratch to incorporate a camera
feed?

Thanks,
Nick

[android-developers] Augmented Reality - Tutorial

[EdwardComb]

Hey Folks,

I am currently interested to create an Augmented Reality application
for Android.
I have no problem to create normal Android application and I am
familiar with IDE, SDK and etc.
But I just have no idea where to start for this Augmented Reality (AR)
stuff.

My intention is actually to make the drawing in the paper come alive
in 3D when using
the Android camera. But most of the tutorial in the web describing
about the GPS and etc.

I really need your help to point me any references I can use to create
the application mentioned above.

Thank's..

[android-developers] Augmented Reality project, help please

[saex]

I have a Augmented Reality App that simply shows the camera view and
get's the user GPS position, azimuth, direction, inclination, etc...
Also i have stored the GPS position of a famous building of my City.
Now i need that when the user faces to the direction of the Building,
a textview ("Building") or a image (the easiest one) must be draw on
the screen in the Building position on the camera.

**I know how to check if the phone is facing the building, i can do
with this code:**

float a =loc.bearingTo(BuildingLocation);
float b =azimuth;
float d = Math.abs((a - b)) % 360;
float r = d > 180 ? 360 - d : d;

Ok, that code gives me the degree diference between what is facing the
phone and the building GPS position. Then, the most the user is facing
the building, the little will be the `r` value. The problem now is
that when the user is at more distance of the building... the angle of
vision is higher, and i dont know how, when and where i have to draw
the textview that i want to put exactly on the building position.

¿How can i do it? I read some accelerometer/compass/gps tutorials but
all of them are poorly explained and didn't show me how to do this,
for example: [http://www.devx.com/wireless/article/42482/1954][1] this
tutorial is very poorly explained and it didn't works when i use the
code, Also doesn't gives me explanations of how to show a point when u
face the object and how to calculate distances

Good tutorials for doing this, and code examples, are welcome.

This is the code i have done. Captures user GPS position (`location`),
azimuth, direction, inclination, etc... and also have stored the
position of the building (`BuildingLocation` `BuildingLat` &
`BuildingLon`).

Help will be appreciated

[android-developers] Augmented Reality Eyes

[SenCogi]

https://market.android.com/details?id=com.xminds.sencogi.augrealeyes&feature=search_result

In no time you can see how you and your friends look with various
colours of eyes!

It recognizes eyes in real-time.
Then when you take a picture it will replace the eyes on the photo
with the type and colour of your choice.

The menu gives you a choice between different human, animal and
extreme eyes.

It works best in normal lighting conditions, avoiding partial shadows
on face and eyes.
The phone needs to be kept in landscape mode.
The ideal distance for the recognition is a profile image of 1 person,
so about 50 cm.
Wait for the real-time augmented overlay of pupils before taking a
photo.
The flash light will improve recognition, also in daytime light.

It works with the normal fotocamera (not the forward-facing
fotocamera, because that has a lower resolution).

[android-developers] Augmented reality: overlaying OpenGL on camera feed without GLSurfaceView

[Nickw]

Hi,

I'm developing an augmented-reality app in which I wish to overlay
real-world data, specifically hiking trails from the OpenStreetMap
project, on the phone's camera feed.

I'm getting this kind-of working, using the camera's SurfaceView
stacked on the GLSurfaceView (yes, that way round, as documented by
several on the web). However you can't always see both layers and in
any case I've seen posts on here suggesting you're not supposed to
overlay two SurfaceViews on each other.

However what I'm struggling to find is an alternative way of doing it.
The method which springs to mind is to draw the OpenGL layer without
using a GLSurfaceView (e.g. just a regular view) but can that be done?
An alternative method is to send the feed to the GLSurfaceView as a
texture but this seems a bit of a long winded way of doing it and if
there are simpler alternatives, I'd prefer to go that route.

On another issue related to the same app, on Android 2.1 (and below)
there is no way to use the API to find any of the camera field of view
parameters, focal length, and so on. The specification for the HTC
Hero does not mention any of those parameters, though I've estimated
in the field a horizontal field of view of just under 40 degrees. It
seems that for 2.1 and below one would have to use some sort of table
mapping phone models to parameters, but again googling is drawing
blanks. Is anyone aware of a list of models and camera FOV parameters?

Thanks,
Nick

Re: [android-developers] Augmented Reality - Please Help

There is Layar API available and wikitude api is also good

But if you are using any of the above mentioned api's then the device must
have the Layar or Wikitude application
installed respectively.

considering the complexity of AR if you wanna develop a stand alone
application then its HARD

[android-developers] Augmented Reality and Spherical 360º Views

[miguel]

Hi, Im working on a AR framework to have the same functionality and
behaviour as Layar or Wikitude does.
Im working hard and now Im totally stuck and missing many hours trying
to fix a problem: I cant get the screen objects to move smooth.

Im trying to figure out how layar, wikitude, skymap or streetview does
to have such a smooth moving overlays that follows the orientation
changes of the devices. But I cant. (PLEASE: google free the skymap
code)
I dont even know if Im focusing the problem well so please, if someone
could help me a bit It would be awesome.

So here are some questions for someone who may answer it:

- Any tip for the sensor noise removal? Low pass filter, threeshold?
both? any value for that filters? I tried EVERYTHING but the smooth
problem may not be just here (so sad)
- Any useful tip to make the overlay views move smooth?

Im using a framelayout witch has a camera overlay on it. Over it I
paint everything else, the radar and its points, a frame, and the
moving views so:
- You think skymap or wikitude use a separated thread just for the
painting?
Should I include all the moving views on a surface or am I doing well?
Do you think they are using openGL?

Thank you very very much in advance. Any help would be appreciated.
Im totally desperate and can go head without this issue solved. Sorry
for my bad english and regards.

[android-developers] Augmented Reality

[bgkarthikeyan]

Hello,

I am developing an application using the WikitudeAPI (Wikitude AR Browser).
But, I am having problem with defining the layout and orientation of the
Cam-view.  I have attached screenshot of the application.

If I select the Cam-View Tab - it starts the WikitudeAR Intent (Which is
another activity).  But I am not able to change the orientation of this
activity.  Whenever I select the Cam-view tab, the orientation is in
landscape and it occurs in full screen mode. What I really want is I would
like to display the Cam-view within the tab-layout.  Will that be possible?

Help me to sort out this problem.

Thanks,

[android-developers] Augmented reality problem with Android 2.2 only, Openg Surface View and Surface View for Camera. 3D Not Rendering.

[dlzerocool]

Hello,

At moment I'm developing an Augmented Reality game, so I'm using the
Hardware Camera and a Surface View to show camera preview.

Everything works fine from what I've been able to test from
Android 1.5 to android 2.1
What goes wrong is in Android 2.2
If I leave the layer from 3D rendering and Camera on the same ordre
than for the previous androids then I don't have the 3D on the screen,
apparently it's drawing it on the back (behind the camera surface).

So Here is the pastebin of the code I have to change (switch the too
layer order in the current layout), also added as attached file.
http://pastebin.com/gyVd0nWR

I've searched for an answer, and have been talking on IRC #android-dev
but apparently it's not very common issue.

What is strange is that there's no release note about 2.2 that this
views have been changed or something else.

The issue is quite easy, but that means I've to have 2 versions on the
market of the same applications.

I hope someone will be able to find why this strange behavior happen
with 2.2

Thank you.

Best regards.

Yvan.

I have several geo points around the user and his phone. I want to
display this point overlaying them on the input from the camera (kind
of standard AR (Augmented Reality) app). Part of my requirements are
that the user can use the phone in either landscape or portrait mode.

My plan was like this.

1. Register for Sensor.TYPE_ACCELEROMETER, Sensor.TYPE_MAGNETIC_FIELD
2. Pass the result to SensorManager.getRotationMatrix(), getting back
the R matrix that should be telling me how to translate points from
the Phone coordinate system (defined here:
http://developer.android.com/reference/android/hardware/SensorEvent.html)
to World coordinate system (x -> East, y -> North, z -> Sky)
3. I want to translate points from World to Phone so I take the
inverse of R (I'm using Matrix.invertM()) to get R_In
4. Using the GPS I translate the geo points I want to display on the
camera to points in the World coordinate system and then I run them
through the R_In matrix to get their coordinates in the Phone system.
5. Draw the points in the screen only if the have (phone coordinates)
z < 0 and x and y such that they are visible...

This is my grand plan... however I have problems quite early (2). I do
get the R matrix back and it looks good when I align the phone to the
world coordinate system ( I get the identity matrix ). However when I
try to translate an imaginary point from the Phone coordinate system
say (0, 1, 0) to the World coordinate system I don't get the numbers I
expect.

For example when i expect (1, 0, 0) i get (-1, 0, 0)
when i expect (0, 0, 1) i get (0, 0, -1)

I haven't done any remapping of the coordinate system and I feel I
don't need too...
Is this the right approach? Any suggestions for me?

Thanks

Hi guys ..

 i am planing to develop augmented reality application for
anrdoid ..can  anybody provide some inputs for that type of
application or  available  example codes for this type of
application ..thanks in advance

Thanks & Kind regards
