We're interested in building an AR experience for the AROne. I've seen that Zeiss has an iPhone app that uses a camera passthrough (called Zeiss VR One AR). Does Zeiss provide any support or SDKs for this AR functionality?
I do not think so, but it is fairly easy to do by yourself, you just have to put a webcamtexture in front of the camera pair.

I am working on a non-audio app for iOS and iPadOS and macOS. This question is specifically about iPadOS for now.
I purchased a generic "USB Volume Control" knob device. I am able to plug it into my (non M1) iPad Pro 12.9 and it does indeed control system volume (rotate), as well as things like rotate through tracks in the Music app (push and rotate), mute (push), etc. I have a second such device from another manufacturer on the way to test with as well.
What I'd really like to do is use it in a non-music context. To be able to capture the raw actions and interpret them in my app's subject domain (DCC model train control).
I have been able, on iPadOS but not iOS [as it doesn't have generic USB support as I understand it] to capture the volume changes by using AVAudioSession and KVO tracking the outputVolume property. I haven't yet figured out how to get the push and push-rotate yet but assume I just need to find the analogue functions in AVAudioSession or some other Apple class.
But I would rather not dink around with the Audio/Music classes and have to "re-purpose" them into my own control needs and was wondering if anyone knew of a way to be able to find and connect to the device and get the values directly.
As iPadOS now has pretty good generic USB support for all sorts of devices, I am hoping there is a way for me to provide service to/with/from those devices but I can't find information through normal internet searches. Poor Google-fu.
I looked at the External Accessory framework but my understanding is that only for MFi certified devices and my attempts to detect the devices have not worked as these are generic USB devices. (Unless there are generic protocols one can register for and make this work).
Thanks for any hints, pointers, admonishments, etc. RTFM is welcome if you tell me the M.
I know this has been all over the net. I browsed a lot and found a lot of information about Gesture recognition .However i got more confused after reading most of them seem to work on Kinect Official SDK , Microsoft's SDK and i don't want to use them.
I need to develop it for Linux and was wondering if OpenNI, NITE gives me the flexibility to recognize a gesture.
I am trying to develop a sign language program, which recognizes the gestures and draws stuff(spheres,cubes etc) on screen,
Could any one give me a clear guidelines to begin this project.I have no clue where to begin it from.
Any help is welcomed.
Thanks
For getting starting with understanding gestures I suggest checking out a blog post I made a while back:
http://www.exceptontuesdays.com/gestures-with-microsoft-kinect-for-windows-sdk-v1-5/
This, plus the post it links to, go into what makes up a "gesture" and how to implement them using Kinect for Windows SDK.
You can also check out thine Kinect Toolbox, which also does gestures for the official Kinect SDK:
http://kinecttoolbox.codeplex.com
These will give you a good understanding of how to deal with gestures. You can then move those concepts and ideas into an OpenNI environment.
If in your sign language system you want to use hand gestures you can have a look at Kinect 3D handtracking. If it includes whole body movement then have a look at KineticSpace. Both tools work for linux but the first tool requires CUDA enabled GPU as well.
I think the Gesture recognition is not depended on whether you use Kinect Official SDK or OpenNI, if you can get the skeleton data or depeth image from the Kinect,then you can extract the gesture or postion from the relations between skeltons with times. As far as i know ,those SDKs are all provide those informations.
I developed kinect on windows ,but the priciple are the same, I still suggest to know the principle about the Gesture recognition, then you can find the way to do recognition using other SDKs.
I'm about to make an application for ipad that has the following specifications:
download JSON (or xml) from server
download short audiofiles from server (locations are in the JSON from above)
save these to the iPad for offline use.
based on these files the user gets to do some exercises
user progress/results need to be saved to the device so they can continue where they left off the next time they launch the app.
My question: Can this be done with only html/css/jquery Phonegap? Or should I go native and make this all in Objective-C? Or can I combine phonegap and Objective-C?
Now I'd like to know how I can save a json file on the device for offline use.
Also I'd like to know how to download audio (or images or whatever) and save those to the device.
This can be done with PhoneGap/Cordova and its HTML5 approach.
If it is iPad only, then go native.
Your app's high level requirements do not sound too complicated. For more complex apps always consider that facebook just went native for iOS because of their performance issues. In the end, this may be the way to go for a number of apps. PhoneGap or other HTML5 or cross compiling approaches for 1000+ devices plus native solutions for the market leaders.
It depends on what level UX your are aiming for and how you think your app may expand in the future.
If you need full control over the user experience, then you will need to go native. All the physics involved in scrolling/swiping will be done for you. How much content will you have? if it's thousands of items then again native will offer the best performance. You can also perform certain tasks on background threads (my app did image compression and resizing before uploading the image, for example).
Otherwise - if you just want to get something out quick, go with phonegap.
*I speak as a developer who started out with Phonegap but went Native for performance reasons. Others may have had better experiences.
Comparing application build in native Objective-C with applications build with Webtool like PhoneGap, in terms of being fast, Objective-C apps always win, but in terms of building it fast with zero knowledge of Objective-C Web apps win.
If you have knowledge of Objective-C, in my opinion go with native Objective-C app, else do it with PhoneGap.
BTW, those functionality mentioned in your question can be done with both.
I'm developing a typical "Windows GUI" based app for iPhone using MONO technologies. I need to add a little AR based functionality to it. It is just about opening up the camera, and showing information to the user regarding nearby businesses.
How can I do this using mono?
Of course it is possible. I have created a project and works very nice. It is quite complicated and I would need three pages to explain it and, the time to do it which I do not have.
In general, you need to look into:
CLLocationManager for location and
compass.
MapKit, if you want to provide
reverse geocoding information.
Implement an overlay view over the
UIImagePickerController which will
act as your canvas.
And of course, drawing.
I hope these guidelines will get you started.
Simply I am asked to write an application for a smart device (smart cell phone), which will get the GPS coordinates from the device itself.
I have no smart device at all. And I am kind of lost among questions like how can I check if the device have a gps by using the code, if it has how can I obtain them in a "standard" way, do I need to be using frameworks like GeoFrameWork?
So, may somebody list the must or most required things I need to have ready?
Geoframeworks GPS.NET is free these days and it's pretty comprehensive so there's no point reinventing the wheel. It's also friendly to beginners which helps. I strongly recommend downloading it and playing with some of the sample apps. It's a bit tricky if you don't have a physical device to play around with but it does have GPS emulation classes that you can use.
All you need is a copy of VS2008 Pro with the Smart Device SDK installed.
