1ST Assignment - Marker AR - Week 36

 

1st Assignment - Vuforia Marker AR
Week 36


    For our first assignment of this course, we had to make a marker-based Augmented Reality Unity mobile app using Vuforia. This type of AR uses images or so-called markers that are easily recognizable by a camera, in our case a mobile phone camera which triggers additional content on the device according to the position of the marker. These markers need to be as abstract as possible from the surrounding environment. These can be used in cases like a museum showing dinosaurs when a tourist hovers over a QR code with an app on their phone or drink manufacturers include markers on their packages that when scanned with an app show additional information about the product. Even Google uses these to improve location accuracy by scanning for known 'markers' like street signs and comparing the images with Google StreetView images to make a more accurate reading of the user's location.

As our assignment, we have chosen to make a mobile maze game where the goal is to get to the end of the maze using the gyroscope of the device. The 'main character' of our game is a ball that rolls around the maze. For the marker, we have used a maze that when scanned gets turn into a 3D maze that you can play the game on. This game can be expanded to have multiple levels by creating new markers with different mazes on them and adding them to the app. Our target device is an Android phone which led to some very tedious manual re-copying of the application to the phone and re-installing it every time we made a change to our project.

For the movement of the player, we have used the old Unity movement system(Vector3).  
During the development of the app, there were many problems such as our app being dependent on how powerful the target device is. So on different devices results varied. For example, when the app was started sometimes the ball fell through the maze. This was due to the poor performance of the device. 


On this assignment, we all worked together on one computer.

Week 45 - Working on our final assignment

Image
    Working on our final assignment Week 45 This week we met again on Friday to continue on the project. We started with implementing the broom. We found a nice asset for it and put it into our project. As we tried to implement the grabbing of the broom with the VR hands, we had some issues where the broom was always off.  Since we wanted to use the grabbing script from our previous project because it was working well, we thought this would be the case as well. But we were wrong. So after a few hours of frustration, we decided to put the knife into our Harry Potter game and test it. The grabbing of the knife works well and we didn't know where we are messing up with the positioning of the broom. Then we got a brilliant idea to put the knife as a child object of the broom, position the knife handle where we want the hand to be placed on the broom, and get the right position values. Eventually, we removed and the knife itself and made the broom work. Authors: Patrik Horny, Mircea Dob

Week 44 - Starting to work on our final assignment

     Starting to work on our final assignment Week 44 This week we have to start working on our final assignment. Last week we assign everybody to find ideas on what we could do but in classic fashion, we all came up with crappy ideas that were too complicated to implement within our time limits as well as we all have separate bachelor's to write. We eventually did what we did at the start of every assignment. Started browsing the free asset store and looked for everything and anything. We eventually found a package with Harry Potter wands and we got the idea to do a game inspired by the Harry Potter universe.  After some digging, we found an abandoned project that had the textures we wanted. After importing those assets we decided to make a functional map to try it out.  While exploring the map we made using the assets we found, we came to think "why don't we make a game where you can fly in Hogwartz?". After some thinking, we decided this was the right course of act

Personal reflection - Mircea-Ionut Dobre - 293117

 Personal reflection Mircea-Ionut Dobre 293117 First project - Vuforia For our first XR project, we had to make an application using Vuforia for a marker based augmented reality experience. This did not go well to say the least.  We had constant problems with vuforia. At first it seemed quite easy to implement as we were mostly already accustomed to unity from the previous semester but we ran into problems especially when we started building the app going thru multiple versions of Unity and Vuforia before we got one to run. The light in the room was also a problem when the app was trying to get the marker. We also ran into some problems while getting the gyroscope scripts to work with our android test phone. We only had 1 android phone that was not company-locked (companies won't let you install external APKs on your phone if you have a work profile) so we had to use a Chinese phone. After getting past these problems the compile times on a pretty potent gaming laptop were abysmally
