Returning to using markers may seem a thing of the past, and in some contexts, it is not an acceptable solution, but in other cases you may need a marker to show the user that there is an augmentation in a particular place. While technically it may work also without them, thanks to ARCore and ARKit, using markers guarantees that your experience is compatible with all phones.
The preferred way to use AR.js is through markers. It’s not perfect, though and there are also various shortcomings that I will highlight throughout the article, this way you can evaluate if it is the right solution for you. Having tried it, I can tell you that it is truly interesting. Creating an AR experience may be a matter of creating a webpage with 10 lines of code! Very easy to be used, especially because it can work with A-frame.Pretty fast, since it can perform at 60FPS easily.Compatible with all the browsers and all the devices.This means that you can do with it whatever you want (even commercial applications) Completely opensource, with MIT license.

(It’s interesting to notice that the proposed solution can also be adapted to other frameworks, but I discovered it with AR.js, so I will show you how to develop it with AR.js) What is AR.js?ĪR.js is a Javascript framework that lets you offer augmented reality through your browser, created by Jerome Etienne and ma intained by Nicolò Carpignoli. How to solve this problem? Well, a guy named Nicolò Carpignoli has proposed a very smart solution that employs AR.js to create a completely seamless AR experience, and experience you will have time for 😉 WebXR removes some friction from the above process (the part where the app has to be installed)… but anyway leaves a lot of work to be done: the viewer has still to open his/her browser, write down the link, frame your business card and then finally he/she can enjoy your animation.

Thanks to this technology, it is possible to enjoy augmented reality without the need to install any kind of applications on your phone.Īs a developer, you have to create a webpage using the various frameworks through which you can offer augmented reality ( A-frame, the 8th Wall, ARCore, AR.js, etc…), then just provide a link to the person that you want to experience AR and bam, he/she can try your AR experience just through his/her browser without having to install anything! If only there were a way to try AR without installing an app… WebXR to the rescueĪctually, there is a way and it is called WebXR. The process was cumbersome, and also left an app on your phone… an app that was just useful to see a cube pop up from my business card… pretty nonsense, wasn’t it?

The problem of this kind of showcase apps (apart from being useless) is friction: in my case, you had to download an app from the store, open it, frame my business card with the camera of your phone, just to see a cube with my face popping out! Yeah, all the process was pretty annoying You had to download my app, then you could point your phone at my business card and see a textured cube popping out of it! Amazing, isn’t it? (Image by QuickMeme) I did one myself some years ago, even using Metaio, a framework that 4-5 years ago disappeared because it has been acquired by Apple. One of the classical showcase augmented reality apps are AR business cards. We suspect that there are more sophisticated ways to accomplish what Screen Markers does, but the program isn't bad if you need a simple way to create lines and markers on your screen.Mobile augmented reality has many problems that are hindering its success and one of them is the necessity to download applications to enjoy it. The program's Help file consists solely of a list of command line options, but on the whole, Screen Markers is pretty easy to figure out, aside from its abbreviations.
Markers can be saved in groups for repeated use. Users can create markers simply by clicking on the desired location on the screen, but marker position can also be adjusted numerically and users can specify the line length, thickness, opacity, and vertical and horizontal length. If it's obvious to you that "Vlen" means vertical length and "Thkns" refers to thickness, you'll have no trouble getting started with Screen Markers.
The program's interface is all business, and it's adorned with various abbreviations that took us a minute to figure out, though our background admittedly is not in design. It's not fancy, but it will do the job if you need a reminder of an object's size or location on your screen.
Screen Markers is a simple program that does exactly that. Whether you're doing graphic design, Web design, desktop publishing, or some other task where proportions and positions matter, it can be useful to have onscreen markers that denote specific spots on your screen.
