What scalability issues do AR developers need to consider?

由人工智能和领英社区提供技术支持

Augmented reality (AR) is a technology that enhances the real world with digital content, such as images, videos, sounds, or 3D models. AR can create immersive and interactive experiences for users across various domains, such as education, entertainment, health, and tourism. However, developing AR applications also poses some challenges, especially when it comes to scalability. Scalability refers to the ability of an application to handle increasing demands, such as more users, more data, or more features, without compromising performance, quality, or functionality. In this article, we will explore some of the scalability issues that AR developers need to consider and how to address them.

1 Hardware diversity

One of the main scalability issues for AR developers is the diversity of hardware devices that can run AR applications. These devices range from smartphones and tablets to headsets and glasses, each with different capabilities, specifications, and limitations. For example, some devices may have higher resolution, processing power, or battery life than others, which can affect the quality and duration of the AR experience. Moreover, some devices may have different sensors, cameras, or input methods, which can influence the accuracy and interactivity of the AR content. Therefore, AR developers need to consider how to optimize their applications for different devices, such as by using adaptive design, responsive layout, or cross-platform frameworks.

If your art is as portable as possible, you shouldn't have too many issues. Interactivity is coming to the main GLTF spec, which will enable interactivity to be defined portably in the future!

2 Content delivery

Another scalability issue for AR developers is the delivery of content to the devices. AR content can be either local or remote, depending on where it is stored and processed. Local content is stored and processed on the device itself, which can reduce latency and bandwidth consumption, but also limit the amount and complexity of the content. Remote content is stored and processed on a server or a cloud platform, which can enable more and richer content, but also introduce latency and bandwidth issues. Therefore, AR developers need to consider how to balance the trade-offs between local and remote content, such as by using caching, compression, or streaming techniques.

We were able to package content, per experience in our Unity App. This allowed users to find their way to the experience, and once hooked, download just the assets required for that experience. It was the best of both worlds.

In my experience this was one big factor AR applications lacked more depth in the content or were killed before its inception. The key is to identify your target audience and check if streaming and networking are acceptable in the user journey. If not, then it’s better to package the initial content where users can interact enough to generate retention, in the background the app downloads the extra content for later usage. The balance between in-app content and remote can make your AR experience stand out.

3 User interaction

A third scalability issue for AR developers is the interaction of users with the AR content and the environment. AR applications can support different types of interaction, such as gesture, voice, touch, or gaze, which can enhance the user experience and engagement. However, these interactions also require more resources and processing, such as recognition, tracking, or feedback, which can affect the performance and reliability of the application. Moreover, these interactions can also vary depending on the context, such as the location, the lighting, or the noise level, which can influence the usability and accessibility of the application. Therefore, AR developers need to consider how to design and test their applications for different interaction modes and scenarios, such as by using user research, prototyping, or evaluation methods.

Each interaction technique has its pros and cons; You don't want to have expressive gestures or voice if your application will be used in public; Different people and cultures have different expectations when it comes to gestures, touch, and even gaze; Different users have different physical limitations - for example, there are users who can barely touch their pinky finger with the thumb of the same hand. The list can go on and on... The solution to this is, as with any UX development - is to test early and test a lot. Another concern with the user interactions is how easy is it to adapt. Ideally, an interaction would be intuitive and easy to discover. While the idea of "naturalness" is enticing, it may not always be the best choice.

4 Data management

A fourth scalability issue for AR developers is the management of data that is generated and consumed by the AR applications. AR applications can use different types of data, such as images, videos, sounds, or 3D models, which can enrich the AR content and functionality. However, these data also require more storage and processing, such as encoding, decoding, or rendering, which can affect the speed and quality of the application. Moreover, these data can also raise some privacy and security concerns, such as the collection, transmission, or storage of personal or sensitive information, which can affect the trust and satisfaction of the users. Therefore, AR developers need to consider how to handle and protect their data, such as by using encryption, anonymization, or consent mechanisms.

5 Application maintenance

A fifth scalability issue for AR developers is the maintenance of their applications over time. AR applications can evolve and change, such as by adding new features, fixing bugs, or updating content, which can improve the user experience and value. However, these changes also require more resources and testing, such as development, deployment, or debugging, which can affect the cost and efficiency of the application. Moreover, these changes can also introduce some compatibility and consistency issues, such as the support of different devices, platforms, or versions, which can affect the functionality and usability of the application. Therefore, AR developers need to consider how to maintain and update their applications, such as by using version control, documentation, or feedback tools.

In my past experience is that many AR projects are handled as MVP or prototypes, without the full planning which involves maintenance and risk assessment. This means that after a release the application will need major updates eventually. This could disrupt the work done and planned for the team. Risk assessment in AR is vital as tech evolves and costs are added to the project. After initial release we need to define what decisions we can take if the AR tech changes and new requirements are imposed.
