1. Various AR recognition technology that CircusAR app provides

  Single-image recognition

As the most stable and popular form of recognition, it recognizes an image like textbook illustrations, product packages, banners, brochures, stickers, and etc. The recognition rate of such images must be high for stable   contents display. If the recognition rate of the image currently in possession is high, it can be sufficiently utilized. Request a recognition rate test at CircusAR app and make your image an AR content marker.

 Multi-target (image) recognition

It can recognize 5 or fewer images simultaneously. For instance, different content could come up when recognizing Images A and B or Images C and D. Also, it could be set up to bring a single piece of content only when all of the images are gathered. It is often used as educational content or for event purposes.

 Cylinder recognition

As a form of image recognition, it can recognize images on a curved-surface such as one attached on a cylindrical container. It is useful to utilize the outer surfaces of cylindrical products as subjects for recognition.

 VuMarks recognition

As a form of image recognition, it recognizes border image barcodes in the desired shape. Use of VuMarks enables recognition of images whose recognition rates are low.

 Object (3D object) recognition

It can recognize 3D objects such as toys, home appliances, cubes, etc. To increase the recognition rate of an object, the surface of the object to be recognized must be opaque, firm, and possess contrasting colors. If a shadow is cast excessively due to a moving object or a lighting environment, stability may be poor. Object recognition is widely used for product explanation or assembly-type toys.

AR Coloring (3D Coloring)

Coloring pages can be designed as a subject for recognition. When recognize the page after coloring them with color pencil, 3D objects according to the coloring emerge. Widely used in content for education, babies, and infants, it is the recognition method with the greatest potential to be applied in various areas of furniture, fashion, arts, etc.

 Face recognition

It can recognize the locations of eyes, noses, and mouths. Through face recognition, we can plan various events or take funny photos.

2. Create images (targets for recognition) with high AR recognition rate
When developing an AR content with the Image recognition, it is most important to increase the recognition rate of a marker image which is targeted for recognition.
If the recognition rate of the marker is low, the stability of the content becomes poor to generate phenomena such as shaking.

* Recommended design
1. Design with straight lines more than curves
2. Design with clear color contrast and differences in overall brightness
3. Design constituted of diverse and complex patterns
4. Design that creates many red dots when recognized with the CircusAR app

* Things to note for printing
1. Recommended to use printing paper without gloss (Vellum paper, Rendezvous, etc.)
 - If inevitably manufactured with glossy paper, it is recommended to partially give matte coating on image parts to be recognized
2. Design that contains engraved or embossed carving is to be avoided
3. Materials such as acrylic that transparently displays the back side are to be avoided
4. It is recommended to improve the sharpness of images via high-resolution or laser printing
5. Minimum of 5cm is needed for the longer side of an image
6. If the cut region of an image is changed, it may be recognized as a different image so it is recommended to maintain the original image of the marker
3. Types of AR and VR applications (Pros and cons of Cloud type and Embedded type)
To produce an customized app for specific AR content, the form of AR app that suits the purpose and environment of the content must be selected.
It is possible to only request production of AR content without making a separate app, and publish with the cloud-type CircusAR app.

→ Q&A

For VR content in the form of simple 360° video, an existing player that supports 360° features such as Youtube may be utilized without having to make a new app. 
A customized app is required to make VR content that contains interactions(3D). The content may be enjoyed in two forms, which are an <Immersive View> utilizing the direction sensors of smartphone devices and a <Dual-eye View> that requires HMD, and both forms can be implemented in a single app.
4. CircusAR’s CMS solution
CircusAR’s CMS (Content management system) is a work-management system that produces AR and VR content, establish and revise statistics databases, etc.
All of the content that currently runs on the CircusAR app is being published through CMS, and it boasts convenient usage.

The services provided through CMS are as follows;

- Customizing AR content
- 2D+sound slide brochure content
- 2D photo-taking content
- Video content
- Sub button inserted content
- Multi-language support (Korean, Chinese, Japanese, English)
- Database of scan traffic, country, time, device, model names
- Mission-type events
- Web slides
- Stamp rally
- CircusAR app control

※ It is not open to the public yet and will be open as a paid service in the future.
5. Concept of AR, VR, MR, and XR

- AR (Augmented Reality)
AR is technology that overlays the content created by a virtual computer (the “CG contents”) onto reality in real time.

- VR (Virtual Reality)
VR, which contains all immersive experiences, is technology that combines 360˚ videos and CG content to offer new experiences.
The virtual reality market in diverse scopes including WebVR and mobile- and PC-based VR is on display.

It uses HMD to allow users to feel like they are actually in a virtual space.

- MR (Mixed Reality)
MR is technology that erases the boundary between AR and VR and enables a CG object to understand the distance from the object in a real environment as well as its location, angle, height, etc.

Simply speaking, unlike AR, MR can recognize a table and, thus, produce contents with the concept of a virtual puppy hiding under the table.

- XR (Extended Reality)
XR refers to all real and virtual environments created via CG and wearables.

It is technology in which various forms of technology that can combine virtual information and reality are converged regardless any distinction between AR, VR, or MR, or a term that encompasses all content of an expanded concept that utilizes such technology.

6. What is Magic Marker?
Magic Marker is a multi-purpose marker (target for recognition) developed by CircusAR app for more diverse AR experiences.
AR content loaded from the contents list within the app may be enjoyed by ether recognizing the markers or attaching them to Magic Markers.
