For most of human history, shipping goods was a leap of faith. Medieval merchants risked entire fortunes on seaborne exports. All they could do was hope the fleet arrived safely at foreign ports. Often, it didn’t.??

And while piracy and shipwrecks are a lot less common today, many supply chains still suffer from a lack of visibility, compounding risk on risk. The leap of faith is still with us—but it doesn’t have to be.?

'Bluetooth Low Energy is particularly helpful in battery-powered asset tracking systems, and when you’re tracking shipments across long journeys, battery power is often the only viable option.' -Digital MatterClick To Tweet

The maturity of cellular networks such as LTE-M (Cat-M1) and NB-IoT has been combined with innovative asset tracking devices to provide consistent, often near real-time visibility for valuable assets as they move. It’s not surprising that the IoT asset tracking market is projected to expand at a compound annual growth rate of 11.3 percent through 2027, reaching a global value of $6.6 billion by that year. But for some assets, location data—the primarily GNSS-driven center of most asset tracking systems—isn’t enough.?

Take cold chains, for instance. When you’re shipping a vaccine or frozen foods, you need precise, reliable temperature monitoring. Typically, the asset tracking devices that accomplish this task are hard-wired into reefer trailers. That doesn’t help when cargo leaves the trailer. For consistent measurements, you need battery-powered devices capable of condition-monitoring and maintaining asset-level visibility

Until fairly recently, however, battery-powered IoT asset tracking devices struggled to meet the need. Always-on temperature monitoring required too much power. SIM-connected sensors were too expensive to scale. That’s all changing, thanks to a surprisingly familiar technology.?

New applications of this trusty short-range wireless technology standard are creating powerful new opportunities for asset monitoring within broader asset tracking systems. That tech? Bluetooth, specifically a low-power twist on the same technology that launched a thousand wireless headphone brands.?

Here’s what every shipper, carrier, and supply chain stakeholder should know about the asset-monitoring capabilities of Bluetooth Low Energy.?

Getting More for Less with Bluetooth Low Energy

Bluetooth Low Energy connects devices in relative proximity while drawing up to 10 times less power from devices than traditional Bluetooth. It’s an energy-efficient, low-cost way to transmit data from an array of sensors to a central gateway. Then the gateway harnesses WiFi, cell towers, or both to send that data to decision-makers, wherever they’re located.??

The low-power capability of Bluetooth Low Energy is particularly helpful in battery-powered asset tracking systems—and when you’re tracking shipments across long journeys by rail, road, air, and/or sea, battery power is often the only viable option.??

Bluetooth tags are sensors that you can attach to just about any asset, from a full pallet load to a single, high-value piece of equipment. A vast and growing ecosystem of Bluetooth Low Energy sensing devices allows shippers to maintain a constant stream of actionable data about their property with precise measurements on things like:?

? Temperature

? Impacts

? Humidity

? Movement

? Door status (open/closed)

Bluetooth Low Energy tags don’t require SIM cards, and they’re generally cheaper than a standalone cellular tracking device. That means Bluetooth Low Energy allows you to track more for less: More assets. More conditions. More insight. All with less power and less cost. But how does it work????

Bluetooth Low Energy Devices in the Asset Tracking Technology Stack

Adding Bluetooth Low Energy devices to an asset tracking sensor array is simple. You just need the following components:?

? Bluetooth Low Energy tags, which can track approximate location, temperature, humidity, door status, and more.

? A Bluetooth Low Energy gateway, which bridges the gap between devices and the cellular (and/or Wifi) connections that send that data to your asset tracking platform. Choose a GPS asset tracking device with Bluetooth Low Energy connectivity for full-service asset tracking with valuable focused condition data.?

? The cellular connection, via LTE-M or NB-IoT. Look for asset tracking devices that support automatic roaming between LTE-M and NB-IoT networks to improve global coverage.?

? A customer end-point: the mobile apps or desktop platforms that receive, process, and organize location and condition data for use.?

The diversity of Bluetooth Low Energy tags in a rapidly evolving market creates a plug-and-play ecosystem. Today, you can mix and match sensors to customize your data capture—but only if you choose the right Bluetooth Low Energy gateway, the heart of your asset tracking and monitoring system.??

What To Look For in an IoT Asset Tracking Bluetooth Gateway

To build an asset tracking/monitoring solution that tells you exactly what you need to know, start by finding the right asset tracking device, which doubles as a Bluetooth Low Energy gateway. Here are the technology features you need to get the best results:?

? Single-deployment battery life. Battery-powered asset trackers/gateways create more opportunities for supply chain tracking and monitoring. You can place them anywhere, even on rented equipment, because you don’t have to hard-wire them to power sources. Some of today’s asset tracking edge devices boast a battery life of up to 10 years at a time, so redeployment doesn’t become an issue.?

? Open Bluetooth Low Energy ecosystems. Watch out for gateways that are only compatible with a single manufacturer’s products. That locks you out of the open market, which can provide a wider variety of measurements as well as lower costs than a closed Bluetooth ecosystem. Instead, look for an open ecosystem that works with third-party accessories.???

? Signal filtering. Some gateways pick up any Bluetooth signal in the vicinity. That can cause problems in, say, a busy distribution center, where workers may use Bluetooth voice-picking systems, or even just personal headphones. Choose a gateway that can filter out these signals to keep data streams clean and uncorrupted while reducing data costs and server loads.

With the right gateway on hand, you can take full advantage of the monitoring capabilities made possible by Bluetooth Low Energy. In other words, you get more for less, and can finally consign the shipper’s leap of faith to the dustbin of history.?

Metaverse App Development Guide for Business Leaders

What once began as a revolution of communication in the form of text, images, and two-dimensional formatting is now evolving into new dimensions. The metaverse has been with us in one form or another for some time, but the progression of critical technologies has vastly pushed the envelope of how we define and use the web. As a business owner looking to remain competitive in the future, you need to stay informed on the technologies involved in this space if you are to develop applications and even entire digital worlds for your customers.?

Let’s talk about what technologies are used in metaverse app development and how businesses can create their own metaverse applications.

'The metaverse is not simply a new, digital world. It is the intersection and seamless crossover between the real and digital world.' -MobiDevClick To Tweet

The Metaverse for Business Explained

Neal Stephenson’s Snow Crash coined the phrase that became the name for the metaverse, and executives like Mark Zuckerberg are fulfilling the book’s prophetic predictions of business, the economy, and society. The metaverse, as it is understood in modern business, is an immersive next step of the Internet where users participate in virtual, immersive worlds.?

It’s clear that the future of the Internet will arrive sooner rather than later. According to Bloomberg, metaverse technologies will be an $800 billion market this year in 2022. If businesses want to remain relevant throughout that evolution, it’s important that they stay on top of the technologies driving the development of ‘web 3’ forward.?

Technology Map for the Metaverse Development

There are a number of different technologies that are powering metaverse development. Understanding each of them and recognizing where they intersect is critical to innovation.?

Augmented Reality (AR) and Virtual Reality (VR) in the Metaverse

Virtual reality is one of the most prolific technologies moving the metaverse forward, but it has several limitations. Since these are emerging technologies, the world isn’t quite ready for widespread, easily accessible VR. First of all, this is due to limited mobility. In order to experience virtual reality, the user needs a special VR headset, which is quite bulky and doesn’t allow the head or body movements needed to get the full experience. Moreover, the cost of VR devices is quite high, and there are no standards for virtual reality yet, so content created for one platform may not work with another.

“Augmented reality is a more accessible technology that is breaking the boundaries between the real and digital worlds. It’s available on nearly all modern smartphones, making it a viable option to support a freer and more open metaverse. Even though AR doesn’t provide a fully immersive experience, overlaying images and information over the real world may be a more effective strategy for companies this early in the game,” – says Andrew Makarov, Head of Mobile Development at MobiDev.

Another way that augmented reality can be used for more immersive experiences overlaid on top of the real world is through the ‘try before you buy’ retail strategy. Through the use of virtual fitting room technology or similar technologies, shoppers can try on items virtually with AR before they decide to make a purchase. IKEA Place is a great example of how this functionality extends to furniture and interior design, since it allows shoppers to place virtual furniture in their house to see how it may look before they buy it.?

Natural Language Processing (NLP)

A subset of artificial intelligence that is important for the development of the metaverse is natural language processing. This is an advanced way for AI to interpret and emulate human speech. Not only will this be a great way for users and AI to interact in the form of customer service chatbots and virtual assistants, but it can also make the metaverse more accessible to diverse groups of people. For example, conversational artificial intelligence enables rich real-time language translation, even though it’s a challenging task.?

In fact, there is a non-monotonic relationship between the source speech and the target translations. It means that the words at the end of the speech can influence words at the beginning of the translations. So, there is no real real-time speech translation because there is always the need to check the translated text’s consistency against the original speech (so-called re-translations). There is always a small delay even if you can’t see it. Therefore, you need advanced algorithms to stabilize the translation of live speech, as Google does in its Google Translate to reduce the number of re-translations.

Internally, real-time speech translations may be organized as follows: the user says something, the user’s speech turns into a text, and the text is then translated into the other language. After the speech is paused/ended and the final re-translation is done, the text turns into a speech using speech-to-text technologies.

NLP also can provide live captions for users with hearing impairments. For example, AI technology can instantly transcribe the conversation of a group of people, making communication within a metaverse application accessible to users with hearing disabilities.

Virtual Assistant Technology

NLP also makes digital voice assistants and AI avatars possible that can help users with the hands-free operation of their devices as well as offer targeted suggestions. Meta is already developing a voice assistant that will be used in metaverse applications in the coming years. Virtual assistants can perform language translation, financial management, and much more.

The representation of users in the metaverse as AI avatars or digital humans also relies on NLP. Conversational AI allows avatars to process and understand human language as well as respond to voice commands. Last year, NVIDIA introduced the Omniverse Avatar modeling platform. It allows you to create virtual versions of people who not only recognize speech but also capture emotions on the faces of users.?

NVIDIA’s Omniverse Avatar

One important role that virtual assistants can help with in the metaverse is customer service. Since shopping experiences in the metaverse will be highly immersive, conversational AI will be very useful for allowing shoppers to ask virtual customer service avatars about the characteristics of the goods, payment terms, discounts, and the like.

Computer Vision

Computer vision can enable machines to better create digital copies of objects, recognize images and patterns, and even recognize the expressions and moods of users.?

One of the limitations of VR and AR experiences is control. Hardware controllers, gloves, or other kinds of physical devices can be used to input into the device. However, computer vision can help make this experience more natural by using hand tracking. By recognizing gestures and finger positions, users can interact with their devices more naturally and freely.

AR hand-tracking demo by MobiDev

This is an example of how it can work. AR implementation includes the coordination of both the cell phone’s video camera and LiDAR. A video camera captures the image/video of the real world and the user’s hand. LiDAR estimates the distance between real-world objects and the user’s hand. With that information we can correctly place some virtual objects on the phone screen, so from the user’s perspective, the virtual object looks like a part of the real world.

With the help of computer vision technologies, we can recognize if the user tries to interact with the virtual object with the hand. Examples of such interactions can be putting the virtual object in a cart in a virtual shop or animating objects (useful for AR-interactive games).

Computer vision in the metaverse doesn’t just stop there. ReadyPlayerMe uses face recognition to create a virtual avatar from a user’s selfie. Most video games and platforms require users to create a brand new avatar to use for each service. However, these avatars created by computer vision are designed to be used across thousands of different platforms.

Internet of Things (IoT) and the Metaverse

Artificial intelligence is just a part of the metaverse story and it’s usually not the answer to every problem that developers face when making metaverse projects. AI needs high-quality data, and that data needs to come from somewhere. Internet of Things devices and sensors are critical for providing high-quality real-time data to AI systems for analysis.?

One of the most useful applications of IoT in the metaverse is digital twins. This technique utilizes IoT sensors to create a digital version of an environment or system. With VR relying heavily on virtual environments, being able to create a virtual representation of an environment using sensors is in high demand.?

The metaverse is not simply a new, digital world. It is the intersection and seamless crossover between the real and digital world. Using augmented reality technologies with IoT sensors to bring the real world into the digital, and the digital into the real world will revolutionize metaverse technologies.?

The Blockchain’s Role in the Metaverse

As a global and decentralized system, blockchain platforms are in demand for use in metaverse projects. Centralized data storage is problematic in the metaverse because of the barriers to the flow of information. A more open solution like a blockchain can allow for a more fluid flow of information and proof of ownership for digital assets. Due to this, there is high demand for the development of systems that can support cryptocurrencies and non-fungible tokens.?

Non-fungible tokens or NFTs, today are the most promising way to develop the metaverse economy. Since each token is unique, it can be a reliable proof of digital ownership recorded in the blockchain. For example, users can buy in-game assets and digital real estate in the form of non-fungible tokens representing the right to own these items.?

3D Modeling?

With the metaverse relying heavily on virtual worlds, 3D modeling is a skill that’s in high demand. From decorating homes to creating skins for avatars, modeling is something that virtual worlds can’t do without. With such a large number of objects that need to be digitized, it’s clear why IoT sensors need to be used to create digital twins of environments. Large databases need to be made of real-world objects that have been ‘3D captured’ and digitized.?

However, there are challenges to the digitization of the real world. The higher resolution that an object is digitized with, the greater the memory it will use. Finding space for all of these objects and rendering them on lower-end hardware isn’t always possible. This is especially challenging for VR support. VR experiences have to be rendered at higher frame rates to maintain immersion. However, if all the objects in a scene have very high poly counts, then performance could take a hit. Managing this is critical for providing successful metaverse experiences.?

Metaverse Software Development: How to Start a Project

As we continue into the wild west of the development of metaverse and web 3.0, there are countless opportunities for ideas to flourish. Whether these ideas ride the wave of disruption that these technologies bring to the table or if these ideas extend the potential of your business to reach new markets, keeping your business competitive is a must.?

As an example, let’s say your team wants to build an immersive retail store based on metaverse technology. To build this, the project would need either a fully 3D VR environment or objects to serve as products. This virtual store would also need digital customer service agents to help users find what they need.?

The metaverse use cases don’t stop there. It could be a virtual meeting room where you and your colleagues can interact as avatars. Or imagine how cool it would be if a designer could place decor and change the color of walls and furniture right in the VR metaverse. Modern technology makes all this possible.
