What is the basics of ARKit
ARKit combines device motion tracking, world tracking, scene understanding, and display conveniences to simplify building an AR experience.
How does ARKit work?
ARKit recognizes notable features in the scene image, tracks differences in the positions of those features across video frames, and compares that information with motion sensing data. The result is a high-precision model of the device's position and motion.
What are the features of ARKit?
Some of the greatest features that ARKit has to offer are object and scene recognition, meshing, geographic tracking, face tracking, and more. ARKit is often compared to its Android competitor, ARCore. Just like ARKit, ARCore can make it possible to utilize the full potential of an Android device for augmented reality.
How does ARKit detect planes?
In ARKit you can specify that you want to detect horizontal planes by setting the planeDetection property on your session configuration object. This value can be set to either ARPlaneDetectionHorizontal or ARPlaneDetectionNone. This method gets called each time ARKit detects what it considers to be a new plane.
What are the system requirements for ARKit?
To experience augmented reality, ARKit requires minimally A-9 processor hardware and iOS 11 software, and additionally a real camera. For this reason, you cannot simulate your project with Xcode Simulator. You would have to make use of one of the following Apple devices: iPhone SE, iPhone 6s and later.

Can ARKit use both cameras?
iOS devices come equipped with two cameras, and for each ARKit session you need to choose which camera's feed to augment. ARKit 3 and later provide simultaneous anchors from both cameras (see Combining User Face-Tracking and World Tracking), but you still must choose one camera feed to show to the user at a time.
How accurate is ARKit tracking?
Our results indicate that ARKit is capable of producing accurate measurements, with overall errors ranging between 0.88% and 9.07% from the actual distance, across various head positions.
What are the benefits of ARKit?
AR content realistically passes behind and in front of people in the real world, making AR experiences more immersive while also enabling green-screen-style effects in almost any environment. Depth estimation improves on iPhone 12, iPhone 12 Pro, and iPad Pro in all apps built with ARKit, without any code changes.
Does ARKit use LiDAR?
Overview. On a fourth-generation iPad Pro running iPad OS 13.4 or later, ARKit uses the LiDAR Scanner to create a polygonal model of the physical environment.
How does ARKit face tracking work?
When face tracking is active, ARKit automatically adds ARFaceAnchor objects to the running AR session, containing information about the user's face, including its position and orientation. (ARKit detects and provides information about only face at a time.
Is ARKit better than ARCore?
Improved tracking. ARKit tends to perform better than ARCore in terms of image tracking and recognition. If you intend to create AR apps that track user gestures to manipulate on-screen images, ARKit will usually be the more efficient option.
Can ARKit create a 3D map of the environment?
ARKit can do even more: the iOS camera maps out the immediate vicinity as the device moves through space. By cleverly combining information from the motion sensors and camera images a very accurate 3D map of the environment can be created.
Does ARKit work with front camera?
Regarding the front-facing camera: in short, no. ARKit offers two basic kinds of AR experience: World Tracking ( ARWorldTrackingConfiguration ), using the back-facing camera, where a user looks "through" the device at an augmented view of the world around them.
Why should my students use AR?
AR can enhance learning by providing students with multiple ways of accessing and engaging with the content. For example, AR can help students visualize complex concepts, such as anatomy, physics, or geography, by showing them 3D models or simulations.
What is the difference between ARKit and LiDAR?
The LiDAR Scanner quickly retrieves depth information from a wide area in front of the user, so ARKit can estimate the shape of the real world without requiring the user to move. ARKit converts the depth information into a series of vertices that connect to form a mesh.
What do 3D Vtubers use for face tracking?
VTube Studio supports face tracking via webcam (using OpenSeeFace) or by using a connected iPhone/Android device as face tracker. On iOS, you need a device with FaceID or the Apple A12 (or newer) chip. On Android, you need a phone that supports Google ARCore.
What are the advantages of ARKit?
Improved tracking. ARKit tends to perform better than ARCore in terms of image tracking and recognition. If you intend to create AR apps that track user gestures to manipulate on-screen images, ARKit will usually be the more efficient option. It translates movements into data faster than Google's alternative.
What are the disadvantages of ARKit?
iOS's only. As with many things Apple ARKit is an iOS only framework not available for Android apps. If you are serious about cross platform and feature parity you will need to bring the same capabilities to iOS & Android.
What software is used for 3D mapping?
Autodesk's 3D mapping software suite includes AutoCAD, the AEC Collection, Inventor, Revit and Recap. 3D mapping is often used by advertisers and artists to add dimension, movement and depth to previously static objects such as buildings or stages.
What is AR zone camera?
AR Zone app allows users to experience augmented reality on Samsung Android devices. The users have the liberty to choose a feature and capture photos and videos with all the fun elements. You can add virtual items such as emojis, clothing items, makeup, or furniture to your images and videos.
How is AR used in teaching?
AR in Education:
Augmented Reality learning technology allows teachers and educators to incorporate personalized, game-based learning that extends beyond the classroom. Use of AR in education sector improves the learning environment by driving student engagement and experience.
What is the main use of AR?
Augmented reality either makes visual changes to a natural environment or enhances that environment through adding new information. It can be used for a variety of purposes, including gaming, product visualization, marketing campaigns, architecture and home design, education, and industrial manufacturing, among others.
How accurate is ARKit?
Our results indicate that ARKit is capable of producing accurate measurements, with overall errors ranging between 0.88% and 9.07% from the actual distance, across various head positions.
What technology do VTubers use?
As mentioned, motion capture technology is the foundation of VTubing and enables the creation of a virtual avatar that can mimic the movements and expressions of the performer. VUP, Live2D and 3D modeling tools like Blender are a few common motion capture technology possibilities.
What app do VTubers use to make their characters?
Once you've got an avatar, you need to import it into software that can retarget the motion capture data and render your character in real-time. The three most popular free tools that VTubers use to create content are VUP, Vtube Studio, and Amimaze by Facerig. All three are free to use and have paid versions.
