i'm trying to develop a small application that is able to track the position of the user indoors. I also want to create a small map of the building floor, so the user can see a image of it and his/her current position as they travel though the building. They would be able to connect via wifi.
Are there any tutorials/examples of how to create a navigational map indoors on the iphone? furthermore is it possible to accuratly track the position of the player by the use of wifi indoors?
Your second question is IMHO much more crucial, and the answer is "not very easily, and not very accurately". You'd have to see multiple APs (4+) located at well known positions at the same time, and triangulate your position from the signal strengths. This would also require that the phone scans for networks all the time but doesn't connect to any.

I'm working on an application where the concept is that you can 'select' objects before actually placing them. So what I wanted to do was have some low quality objects on a shelf or something like it. When the user selects the object he then can tap to place the high quality version of the object in his area for further viewing.
I was wondering if it's possible with vuforia. I wanted to use this platform since it works well from what I could tell and it's cross platform (The application needs to be for android and the HoloLens).
I have set up the basic application where you can place a capsule in the area. Now I wanted to automatically place the (in this case capsule) once vuforia has detected a ground plane. From what I could see the plane finder has events that go off when an input is detected, but I couldn't find an event that goes off when the ground plane is detected. Is it still possible with vuforia? I know it's doable with the HoloLens, but I would like to know if it's possible for android or other mobile devices. I really don't know where to start/look for so I hope someone can point me in the right direction.
Let me know if I need to include more information!
The Vuforia PlaneFinderBehaviour (see doc here) has the event OnAutomaticHitTest which fires every frame a ground plane is detected.
So you can use it to automatically spawn an object.
You have to add your method in the On Automatic Hit Test instead of the On Interactive Hit Test list of the "Plane Finder":
I've heard that vuforia fusion, does not yet support ARCore (it supports ARKit) so it uses an internal implementation to simulate ARCore functionality, and they are waiting for a final release of ARCore to support it. Many users reported that their objects move even when they use an ARCore supported device.
I just want some hint of how can I create an app in iOS which can do following.
When a user is at point X, user will click on start button so app will start a timer and track the movement. User will be on a horse and user needs to ride in a full circle. When user comes back to point X the app should draw the route taken by the user on the horse.
Aim is to ride completely in a circle. I want to make this app to
practice and see how close to a circle I ride.
I tried to look at GPS locator but I am not sure whether it will give me efficient results because the circle I ride can be as small as 60m or less in radius.
I don't know if iOS GPS can be this accurate. I read article on motion sensor and how to track rotation and acceleration.
But I am not quite sure how to use that to my advantage.
I just need some tips like which API to use etc.
Using the Standard Positioning Service one can achieve 15 meter
horizontal accuracy 95% of the time. This means that 95% of the time,
the coordinates you read from your GPS receiver display will be within
15 meters of your true position on the earth.

For integrate Map and draw path using current position google map is good option for integrate in iOS mobile .
small and range and get accurate result use indoor position system.

I downloaded the Indoor Atlas iPhone SDK and also generated path maps and test paths for my venue. SDK navigates me perfectly when I am moving from one place to another but when I stop moving it generates scattered output with the position radius from 10 to 25. I am expecting precise co-ordinates in both the above cases in my project.
Is there any way to get more precision?
IndoorAtlas technology is using the history of magnetic field observations for computing the precise location. This means that the device needs to move some distance in order to collect enough data to converge to a correct location estimate, i.e., to have a location fix. We are constantly improving our service to decrease the time needed for the first location fix.
If you experience your position moving after you've already stopped walking yourself, please contact support#indooratlas.com with details of your application and venue where this is experienced and we'll look into it. Thanks!
I have a requirement mentioned below:
Already have a floor plan map image
First detect current location on floor
Then select the destination location using floor plan map image
Now application should provide direction & distance for that source to destination path
This is like how google direction works, but its in-house map require.
For example,
- Current position of user is: At his desk
- Where is Meeting Room #11
- So application should provide direction and distance updates on the map/floor plan image.
Any kind of suggestions/help would be great.
Thanks in advance
Couple of points...
You could create various audio files and play them as way points based on routing. Same principal as 'turn right at the next light'.
Definitely want to set your accuracy to: kCLLocationAccuracyBest. But this will still probably only get you accuracy of around +/- 10 meters at best.
Do a floor plan overlay using MapOverlayView.
If you are indoor, iPhone uses cell towers or WIFI for a location fix. This might be a problem for you because if you are looking to map multiple floors, only GPS can give you altitude readings - ground floor, second floor, etc...
I don't want to pour cold water on your idea but I have not heard of anyone successfully doing an indoor navigation app on an iPhone using standard stuff. If you really wanted to move forward on this project, your best accuracy might be using indoor bluetooth transmitters as navigational beacons...?
What you want is path-planing in the map, is that? If so, there is lot of algoritms you can use. You can choose a block size based on your map and resolution needs, divide de map into this, amd mark each block as navegable or not. Then getting from the first block trying in the direction of the destionation block, check if the neighboor block is blocked or not, and get going, until you reach (or not, if its not reacheable) the destination block.
Thats a pseudo-implementation, you have some option to do it, if I understand your needs.
(I dont know your hardware as said by others, with simple GPS and indoor navigation, assuming a 15m resolution is a good balance between optimistic/pesimistc signal, If its for robot-navigation, its not a goos approach in the GPS terms, but the algorimt is).
I'm working on a project but i want to try if i can locate my position using 1 wifi access point because i only have 1 at home, or would i need to go somewhere where there are atleast 3?
It depends on how accurate you need the reading to be. A typical wi-fi point will have a range of something like 30m indoors or 90m outdoors.
So, if you can actually locate the wi-fi point perfectly and you don't need better than 90m resolution (although, technically, that's probably an up-to-180m error), one should be fine.
If you need more resolution, the more points you can get (assuming of course the points aren't sitting on top of one another in a rack or something) should allow you to refine your position.
It is like xyz coordinate system. With one Wifi AP you will know the distance from the AP but not the direction. With two wifi APs you will know the location within a 2d plane (only the positive plane). You will need a third wifi AP for the 3rd dimension.
