Coding INDOOR NAVIGATION with A* Pathfinding

Today's Augmented Reality tutorial goes over an ARkit app for Indoor Navigation in Unity. We will go over how to use Placenote for persistent AR and the A* algorithm for pathfinding. Let me know if you guys have any questions in the comments!

[@AnujSharma-yr4rp]

I'm just starting a project using augmented reality and you are truely inspiring! Thanks a lot for these videos!!!

[@MatthewHallberg]

Sooo cool! Glad to help!

[@funbee746]

How do you make indoor map

[@user-li4xb9me2u]

It's the video I've been waiting for a long time ..... Thank you very much Matthew

[@sunnyqureshi2861]

Matthew you are brilliant work in Augmented Reality 😊

[@vladsamonin9794]

Same busy with school. But was waiting for the new video. Going to use the info for AI class seems like very cool project. Thank you for sharing.

[@MatthewHallberg]

Yeahh no prob!!

[@secompartenlibros8241]

Its amazing how A.R. has been growing! Thanks for sharing you knowledge ur videos help me a lot always! . Hope to see this sdk for Android

[@xenithsanguine]

Usage application; Cataloging mom and pop bookstores, and allowing customers to find sections and books simply. Now that's a great business to start!

[@Kazumo]

I'm so happy to see a new video from you, Matthew! Amazing one as always, thanks a lot.

[@MatthewHallberg]

Anytime!!

[@hamzzashaffi]

Finally a new video!

[@lingxianglu849]

Great video! I have been working almost 2 months to use filtering method combining RSSI beacon and gps result for higher localization accuracy, but it never work so well, placenote is definitely worth to try!

[@Spencergolde]

Yeah RSSI is never a reliable system for at least a couple reasons. The main one that limits it's usefulness over time is that fine measurements taken one day can be completely different the next day if someone moves a metal shelf or a new router gets connected or whatever other reason. There so many opportunities for signal strength to change and then you'll be off by tens of meters, useless for indoor navigation.

[@pablogutierrez5461]

Hey Matthew I love what you are doing with your videos they are truly amazing Just wanted to ask if you can make a video on how you used a image in the real world to effect a gun in the vr world Like how you did in Stalk. Thank you for everything and I can't wait for the new ideas you come up with. Have a great day.

[@karlotten8142]

Great stuff! Why can't more KZbinrs be this concise and effective with their content? Question.... What accuracy can you achieve with the placement of these nodes? cm, mm, miro, nano? I am thinking of an industrial application that could use this.

[@seaniethemick]

Mr. Hallberg, your videos are a diamond in the rough. Really great stuff, thank you for doing these. Can you recommend a program for beginners to learn Unity and AR development? Happy Christmas!

[@mk48sz33]

Hi Matthew! Thanks for this amazing video and for sharing your knowledge. How would this work with ARCore or ARKit image marked AR or Vuforia Image Targets? Can I have them both running the same scene? Or do you suggest putting them in two separate scenes? My next question is, how many maps can you create in one scene? Thank you!!

[@shl4905]

Hi Matthew, thanks for sharing this. I encounter a question, after I create my map and read map from Placenote. after startSession called, currstatus of OnStatusChange in ReadMap is always WAITING is there anything I missed? thanks.

[@waihanlim6699]

I like your video very much! So knowledgeable!

[@MatthewHallberg]

Thanks so much!

[@zismat]

Perfect video and channel over all! One quick question ; how big the map can be ? Will affect phone performance or because its cloud based can support larger maps ?

[@mimi7132]

I edited the project to work with multiple maps. Create scene works perfect but I can't see the map. After loading the map: prevStatus is waiting and current is lost then both are lost, and I cant find any points. What can I do to fix that?

[@virajkaushalye6139]

Thanks dude this is amazing!!!!

[@MatthewHallberg]

Hope it helps!

[@aunabbas8582]

Hi. I have question regarding arcore... How to pause or resume the arcore session?... I can't find any code example for it... Also I wanna know... Is it possible to serialize the arcore session?

[@juanm.rodrigo1155]

Hello Mathew, great tutorial on interior navigation. How could the RA be added to the example? I tried to import the 'ARKit1.5' to make RA and I get errors when loading the package, any ideas ?, I would appreciate it. Thank you regards

[@279ann]

That's awesome! Still waiting for android version thx

[@mingzetang3211]

Just curious, is android version now released?

[@honlammatthewtang6527]

Hi Matt, would you mind to teach how to get the app & got the details in the placenote's "place"?

[@joodjindy318]

Hello matthew...awesome!! I have a question....how you move the camera in unity world with the device?

[@denolaa_]

Hello Matthew. Was just wondering if you know what to do when the error message " The associated script can not be loaded. Please fix any compile errors and assign a valid script " ?

[@heroiuraresjustinian4681]

I want to make a 2d indoor positioning(I want to see the position of my drone/robot from above in a pre-made map).Can anyone provide me with any tutorials or suggestions or resources such as programs that would make my job easier?

[@zacharyjohnson2299]

So after you create the map in the app, does the user also need the app or can they scan a QR code which will then show them directions to their destination?

[@omarelherraoui6031]

Can i find the code that you wrote for this, I'm trying to replicate a similar project for school?

[@ronakdarji1960]

Hey bro thanks for this amazing video. I am getting this error while importing Placenote saying "The Associate Screen cannot be loaded". how to solve that?

[@danilobastidas4672]

tengo una duda, si uso unity 401FT en windous 10 tambien funciona.......

[@azizah5020]

How we do the same thing for indoor system but by using GPS?

[@vedoxg]

can you explain how the algorithm gives those green dots whet it finds the obstacle and is that called mapping?

[@abudriaz9678]

hey mattew iam modifying the placenote randomshpes sample app map is creating and loading successfully but how will i be able to give animation to only the last destinition node in it iam not getting it any help?

[@dplumly]

Thanks Matt, worked on iOS 13.1.2

[@RudraSingh-pb5ls]

Where have you uploaded the video to perform indoor navigation in android devices

[@Therahul7175]

This is really cool! I wanted to understand that if you are using gps here than how is the accuracy for the indoor location.

[@ozkanadar2971]

Hello guys! I have build my application but problem is I cannot read map which I saved already. How can I see?

[@averyc7492]

The placenote guys are so cool! Shoutout to PJ and Neil for helping me with their SDK 🔥

[@MatthewHallberg]

Neil is the man! So nice and knowledgeable.

[@hasanthiseneviratne7900]

[@rohith6xt]

Can you list which are the algorithm used in the development of ar

[@aliammar160]

hey Matthew ....how can i render videos on specific gps coordinates????plz help....im stuck with this problem

[@surajshukla345]

Hi Matthew, how can we create an application like vuforia chalk.

[@NabilMajid]

How can i put a 3D object in VR over an image in a specific lattitude and longittude? Do you havr a tutorial?

[@gundeep0]

Is there any way to do the same for browser platform on android and IOS?

[@jaimegomez5639]

Nice video! I will like try to create a spacial app but at this moment PlaceNote don't have support for android, do you recommend other platform to both devices(Ios and android)? tks!

[@najmihamdi9267]

What hardware that we need? Can we make Ar path way and map without use bluetooth beacon

[@tolcserygergely5389]

Hey, thank you for the video! I'm just started to plan a little AR treasure hunting app, what will operate only in my apartment. I'm a programmer but never did anything AR and/or mobile. I'm just wondering, what are the best technologies to use here. - I want virtual marks to appear on strictly specified 3d points (x,z and y too) - I can't put any marks on the places, to drive the app - I can teach the 3D space to the app before the using - in general - but I can't garantee, that every little thing will be on the same place (only walls, doors, bigger furnituers) I would like to put a game layer onto it but it's not in AR, just some questions, the gamer has to answer to get the mark of the treasure. - it has nothing to do with AR This thing in your looks nice, but I need it for android, and - if I'm right - they didn't make it for android yet. Thank you for the advice

[@yakshitjain3048]

Hey Mathew Can the project work on multiple floors and staaircases
