Content in the context of Augmented Reality (AR), is defined as the presentation of existing information in a format applicable to the current world-view. This takes the form of visual and/or audio but can also take on other sensory formats such as touch or even smell.
This distinction between content and information is important to understand when considering the functional applications of AR platforms. In simple terms, an AR platform will not create information but rather consume it from existing sources and create, package and deliver it as AR content.
AR platforms such as Appearition’s Experience Management System (EMS), rely on the availability of information to create and deliver contextually relevant content to connected clients. AR platforms should, therefore, be regarded as mediums for connecting to existing data stores and aggregating and formatting that information based upon the context of the intended audience.
There are several challenges facing AR platforms today. At the outset, any effective platform must provide an intuitive user interface that is accessible and available to non-technical users. More often, it will be business staff who will be interacting with the platform to manage and create information and content.
- Access to information
A key concern of AR platforms is access to information. This demands connection and integration to various types of data stores. It comes with adherence to security and authentication protocols, data privacy laws and compliance and the support of various types of data formats such as CSV, XML and JSON.
With this concern comes the fundamental need of having a scalable, robust and highly responsive infrastructure for reliable functional performance.
- Contextualising information
Once information is available to the AR platform, it is important to be able to classify and group it. This will become an integral step in content creation as it will be important to link the context of the audience with the context of the information.
Meta-data is a common concept used in IT systems to help with classification. You can apply meta-data to existing information and then filter and query that when creating content.
- Delivering a good user experience (UX)
A well delivered UX has these two common properties: relevance to what we are doing and is quick to load. The former is something we have already touched on above. The latter is about network latency and is best understood when we think about today’s websites. According to studies, more than 40% of users bounce from websites that take more than 3 seconds to load. This is directly related to internet connectivity speeds and the amount of content being delivered to the browser. The same principle applies to AR experiences, however, instead of the latency concerns of HTML, AR is concerned about the speed of recognition, the stability of tracking and the download and rendering of immersive content such as 3D models or 360-degree videos.
A critical factor for AR is a reliable and fast wireless network connection. Whilst the current 4G technology does enable us to watch videos and images seamlessly, when it comes to immersive AR experiences, content is much bigger and heavier than standard website content. As such, we eagerly look forward to 5G which aims to revolutionise our world again with quick access to immersive content.
Whilst the promise of 5G is very much a future aspiration, there are strategies today that can be considered when designing and building AR solutions with latency in mind. Can you anticipate and pre-download AR content before the user has asked for it? Can you place content closer to the user to minimise too many hops around the world? Can you break up the content into smaller chunks and stagger how and when it’s presented?
In many respects, we are exposed to information all the time and in different ways. Since the dawn of humanity, we have exchanged information by communicating and interacting with each other. We then became exposed to printed information in the form of books, newspapers and magazines. In more recent times information has emerged in the form of TV and radio. Finally, the invention of the internet and social media has exploded our access to information at our fingertips. We use information all the time to make important decisions at work, school, home and in social settings. Filtering and deciphering this information in a way that is relevant to what we are doing now, has always been and will continue to be a struggle.
AR content is the means to access and view contextually relevant information in our world.
