On Monday, Bluetooth's governing body, the Bluetooth Technology Alliance (SIG), announced that Bluetooth 5.1, now available to developers, will bring enhanced location services to Bluetooth-enabled devices.

The key to the AR experience is the ability to determine the exact location of real and virtual objects in a variety of applications and devices. The latest advances in Bluetooth technology may facilitate this location service in the near future.

The new Bluetooth feature will allow the app to determine the orientation of the connected device to the nearest centimeter. In contrast, the location accuracy of smartphone GPS sensors is typically within 4.9 meters (according to the National Oceanic and Atmospheric Administration).

Bluetooth SIG executive director Mark Powell said: "Location service is one of the fastest growing solutions for Bluetooth technology and is expected to reach more than 400 million products per year by 2022. The Bluetooth community will continue to adopt technology. Improvements to further develop this market, better meet market demand, drive innovation, and enrich the technology experience of global users."

With accurate location and direction information, Bluetooth 5.1 developers can connect devices with AR Experience connected together, such as indoor navigation and object tracking.

To date, AR indoor navigation solutions (such as those provided by Blippar and Google) rely on visual recognition of landmarks and waypoints to maintain positional accuracy. In these scenarios, Bluetooth devices can replace visual markers.

AR platforms for corporate business such as Upskill and Ubimax also provide asset management and logistics use. The AR prompt can direct workers to the product in the warehouse or on the shelf. In addition, Bluetooth 5.1 allows software manufacturers to detect Bluetooth scanning instead of barcode scanning.

On the consumer side, the Bluetooth object tracker Pixie has provided an AR experience that guides the user through the approximate location of keys, wallets and other items that are not easily found. Bluetooth 5.1 allows customers to more accurately track the location of items.

ABI ResearAndrew Zignani, senior analyst at ch. "Since the introduction of Bluetooth low power in 2010, developers have been able to leverage Bluetooth to create powerful, low-cost applications for consumers, retail, healthcare, public spaces and manufacturing environments. Location-based service solutions. The new direction-finding feature can help Bluetooth better meet the changing needs of the positioning industry, enabling more flexible, scalable and future-proof deployments, further accelerating Bluetooth's location-based service applications in existing markets. At the same time, it provides additional business opportunities for new apps and applications. "

Bluetooth 5.1 is an attractive opportunity in AR from AR cloud platforms such as Niantic Real World Platform, 6D. Ai and Ubiquity6. Accuracy is paramount in the AR cloud paradigm, which can locate multiplayer gaming experiences and anchor content persistently. Bluetooth can also address the location changes of these new platforms.

"6D.ai CEO and co-founder Matt Miesnieks said: "When determining your location, Bluetooth positioning accuracy will be part of the AR system's challenges, due to the limited range and only the relative position coordinates, so Can't solve all the problems (that is, not latitude and longitude, there are no precise and custom settings when installing the base station). But the AR tracker and AR cloud system should be able to add these signals to their algorithms and reduce the power required to achieve accurate sharing and a durable AR experience. "
