Creative Experiment # 1



3.1           Marker-less Augmented Reality

In this experiment, Unity was used as the interactive software to create the marker-less AR project. For this experiment to work the necessary tools that was installed are, Unity 2018.3.5f1 and Android Studio 3.3. The Vuforia package was built into this version of Unity. It is important to locate the correct paths to the SDK location, so that the build can be done and stored locally in the computer. The player settings need to be adjusted accordingly as well. A short tutorial was followed for this to be done correctly.

Step 1: Open a new project in Unity. Go to File > Build Settings > Select Android and hit switch platform. Right click on the Hierarchy Area and hover on Vuforia engine to select AR Camera. After doing so, open Vuforia Configuration on the inspector box and apply a license key which can downloaded from the Vuforia’s official website.

Step 2: Right click on Hierarchy area, hover over Vuforia Engine then Ground Plane and selected Ground Plane stage

Step 3: After inserting the ground plane stage the following guide has appeared. Then repeat the steps from step 2 until Ground Plane drop list. Select Plane Finder. Plane Finder helps to detect the ground in the real world helps to place object on top it.

Step 4: Go to assets, import assets to import the downloaded model. The models can be in these formats. fbx, dae (Collada), .3ds, .dxf, and .obj files. It is important to make sure the object lies on top of the plane detector so the position values are set to (0,0,0) for (x,y,z) axises.

Step 5: The imported object is set as the child to the Ground Plane Stage. After that the Ground Plane Stage is dragged and dropped into the Anchor Stage under Content Positioning Behaviour Script on the inspector box of Plane Finder. With this the Marker-less AR is done. Simply go to File > Build Settings and hit Build.

Understanding AR with Vuforia

Image
My previous research led me to finding a plugin that is used within Unity to create AR apps. The plugin responsible for this is Vuforia. Vuforia a software development kit for creating AR related apps for mobile devices. It's able to map certain points of an object that is identified as an unique pattern to assign an Augmented object to it. A popular example that uses the AR and rose it's popularity worldwide in a short period of time is PokemonGo.     (The Washington Post,2013)    What is AR? and what does it mean for us? (as explained by IDC) Augmented reality (AR) technology is here now, and companies of all shapes and sizes are utilizing it to change the way work gets done and to drive better outcomes for themselves and their clients. IDC believes that service-based organizations should be among the first to embrace this new technology or they could face near-term disruption of their business. Beyond the service elements within a wide range of ent...

3.3            Interaction with AR Object using Leap Motion For this experiment, Leap Motion sensor is used with an older version of Unity 5.51f1 along with LeapMotion_CoreAssets_4.1.6 and Interaction_Engine_0.3.1. Open a new project on Unity 5.5, Step 1: Import the Packages “LeapMotion_CoreAssets_4.1.6” and “Interaction_Engine_0.3.1” into the project file. Step 2: Find the “Leap_Hands_Demo_Desktop” scene under Leap Motion > Examples > Scenes and open the scene. Step 3: Create a 3D object Plane and position it (0, 0, 0) on (x, y, z) axes. Step 4: Create a two 3D Object Cube and scale it appropriately and place it on the plane. Step 5 : Create Materials to differentiate the colors of the cube from each other and assign them accordingly. Also Click on Add component to add the Rigid Body script to each of them individually. Step 6: Find the “InteractionManager” Prefab and drag it onto t...
