Learn How Google Bests ARKit with Android’s ARCore

Previously, we covered the strengths of ARKit 4 in our blog Learn How Apple Tightened Their Grip on the AR Market with the Release of ARKit 4. This week, we will explore all that Android’s ARCore has to offer.

All signs point toward continued growth in the Augmented Reality space. As the latest generations of devices are equipped with enhanced hardware and camera features, applications employing AR have seen increasing adoption. While ARCore represents a breakthrough for the Android platform, it is not Google’s first endeavor into building an AR platform.

HISTORY OF GOOGLE AR

In summer 2014, Google launched their first AR platform Project Tango.

Project Tango received consistent updates, but never achieved mass adoption. Tango’s functionality was limited to three devices which could run it, including the Lenovo Phab 2 Pro which ultimately suffered from numerous issues. While it was ahead of its time, it didn’t receive the level of hype ARKit did. In March 2018, Google announced that it will no longer support Project Tango and that the tech titan will be continuing AR Development with ARCore.

ARCORE

ARCore uses three main technologies to integrate virtual content with the world through the camera:

  • Motion tracking
  • Environmental understanding
  • Light estimation

It tracks the position of the device as it moves and gradually builds its own understanding of the real world. As of now, ARCore is available for development on the following devices:

ARCORE VS. ARKIT

ARCore and ARKit have quite a bit in common. They are both compatible with Unity. They both feature a similar level of capability for sensing changes in lighting and accessing motion sensors. When it comes to mapping, ARCore is ahead of ARKit. ARCore has access to a larger dataset which boosts both the speed and quality of mapping achieved through the collection of 3D environmental information. ARKit cannot store as much local condition data and information. ARCore can also support cross-platform development—meaning you can build ARCore applications for iOS devices, while ARKit is exclusively compatible with iOS devices.

The main cons of ARCore in relation to ARKit mainly have to do with their adoption. In 2019, ARKit was on 650 million devices while there were only 400 million ARCore-enabled devices. ARKit yields 4,000+ results on GitHub while ARCore only contains 1,400+. Ultimately, iOS devices are superior to software-driven Android devices—particularly given the TrueDepth Camera—meaning that AR applications will run better on iOS devices regardless of what platform they are on.

OVERALL

It is safe to say that ARCore is the more robust platform for AR development; however, ARKit is the most popular and most widely usable AR platform. We recommend spending time determining the exact level of usability you need, as well as the demographics of your target audience.

The Future of Indoor GPS Part 5: Inside AR’s Potential to Dominate the Indoor Positioning Space

In the previous installment of our blog series on indoor positioning, we explored how RFID Tags are finding traction in the indoor positioning space. This week, we will examine the potential for AR Indoor Positioning to receive mass adoption.

When Pokemon Go accrued 550 million installs and made $470 million in revenues in 2016, AR became a household name technology. The release of ARKit and ARCore significantly enhanced the ability for mobile app developers to create popular AR apps. However, since Pokemon Go’s explosive release, no application has brought AR technology to the forefront of the public conversation.

When it comes to indoor positioning technology, AR has major growth potential. GPS is the most prevalent technology navigation space, but it cannot provide accurate positioning within buildings. GPS can be accurate in large buildings such as airports, but it fails to locate floor number and more specifics. Where GPS fails, AR-based indoor positioning systems can flourish.

HOW DOES IT WORK?

AR indoor navigation consists of three modules: Mapping, Positioning, and Rendering.

Mapping: creates a map of an indoor space to make a route.

Rendering: manages the design of the AR content as displayed to the user.

Positioning: is the most complex module. There’s no accurate way of using the technology available within the device to determine the precise location of users indoors, including the exact floor.

AR-based indoor positioning solves that problem by using Visual Markers, or AR Markers, to establish the users’ position. Visual markers are recognized by Apple’s ARKit, Google’s ARCore, and other AR SDKs.  When the user scans that marker, it can identify exactly where the user is and provide them with a navigation interface. The further the user is from the last visual marker, the less accurate their location information becomes. In order to maintain accuracy, developers recommend placing visual markers every 50 meters.

Whereas beacon-based indoor positioning technologies can become expensive quickly, running $10-20 per beacon with a working range of around 10-100 meters of accuracy, AR visual markers are the more precise and cost-effective solution with an accuracy threshold down to within millimeters.

CHALLENGES

Performance can decline when more markers have been into an AR-based VPS because all markers must be checked to find a match. If the application is set up for a small building where 10-20 markers are required, it is not an issue. If it’s a chain of supermarkets requiring thousands of visual markers across a city, it becomes more challenging.

Luckily, GPS can help determine the building where the user is located, limiting the number of visual markers the application will ping. Innovators in the AR-based indoor positioning space are using hybrid approaches like this to maximize precision and scale of AR positioning technologies.

CONCLUSION

AR-based indoor navigation has had few cases and requires further technical development before it can roll out on a large scale, but all technological evidence indicates that it will be one of the major indoor positioning technologies of the future.
