Augmented Reality (AR) and Virtual Reality (VR) have become increasingly popular over the years, with many companies investing in these technologies to enhance user experiences. Ensuring that these applications are of high quality and provide optimal user satisfaction requires thorough testing.

What is augmented reality (AR) and virtual reality (VR)?

Augmented Reality (AR) and Virtual Reality (VR) are two technologies that enable users to interact with digital content in immersive and interactive ways.

Augmented Reality (AR) is a technology that overlays digital information onto the real world. This is typically done using a camera and a mobile device, where the device recognizes the physical environment and displays digital information on top of it. For example, a user can point their smartphone camera at a restaurant and see digital reviews or menus overlaid onto the physical space.

Virtual Reality (VR), on the other hand, is a technology that creates a completely artificial, computer-generated environment. It typically requires a specialized headset or display device that completely immerses the user in a virtual world. The user can interact with this world in a variety of ways, such as using hand controllers or simply moving their head and body.

Why quality assurance and testing is important for AR and VR

Quality assurance and testing are essential for ensuring that AR (Augmented Reality) and VR (Virtual Reality) applications function as intended and provide a seamless user experience. Here are some reasons why quality assurance and testing are important for AR and VR:

  • User Experience: The success of AR and VR applications relies heavily on the user experience. Quality assurance and testing help identify and fix issues that could impact the user experience, such as glitches, lag, or incorrect tracking. By ensuring a smooth user experience, AR and VR applications are more likely to gain adoption and keep users engaged.
  • Safety: AR and VR applications can create an immersive experience that blurs the lines between the physical and virtual worlds. Therefore, it is essential to ensure that they are safe for users. Quality assurance and testing help identify potential safety issues, such as motion sickness, and ensure that applications comply with safety standards.
  • Compatibility: AR and VR applications can run on a wide range of devices with different hardware specifications and operating systems. Quality assurance and testing help ensure that applications work correctly across different devices, platforms, and configurations.
  • Performance: AR and VR applications require significant processing power and can be resource-intensive. Quality assurance and testing help identify and fix performance issues, such as slow frame rates, to ensure that applications run smoothly and efficiently.
  • Functionality: AR and VR applications often have complex functionality, such as gesture recognition or spatial mapping. Quality assurance and testing help ensure that all features work correctly and as intended, providing a seamless experience for users.

By identifying and fixing issues related to user experience, safety, compatibility, performance and functionality, quality assurance and testing help ensure that AR and VR applications provide a seamless, immersive experience for users.

Why preparation is vital when testing on AR and VR products

To conduct effective testing for AR and VR products, it is crucial to consider as many scenarios and angles of perception as possible. While many companies focus on the most obvious factors, such as functionality, there are other important angles to consider.

Before beginning testing, QA engineers should review the product’s scope of requirements and prepare a list of real-world experiences. This helps them understand all potential user engagement scenarios and provides a holistic view of the product.

For VR testing, preparation involves creating a play space and removing obstacles to ensure a clear path. AR testing also requires environmental setup, but existing objects like tables and chairs need to be detected and tagged prior to usage to enable identification during operation.

Measuring performance in the mixed reality world typically involves calibrating sensors and IMUs, checking a series of collective points for frame rates, latency, machine vision, and various optical measurements.

Two key approaches to AR and VR testing – manual and automated testing

When it comes to testing AR and VR applications, there are two key approaches: manual testing and automated testing.

Manual testing involves human testers using the application as an end-user would, to identify issues and bugs that may impact user experience. During manual testing, testers can provide valuable feedback on the functionality, performance, and user interface of the application. Manual testing is particularly effective in identifying issues related to user experience, such as navigation and visual elements, which may not be immediately apparent in automated testing.

On the flip side, automated testing involves using specialized software tools to run pre-defined test scripts, which are designed to identify specific issues and potential bugs in the application. Automated testing can be particularly useful in testing the functionality and performance of the application at scale, by simulating a large number of virtual users. This approach is efficient and reliable, as it is less prone to human error and can quickly identify bugs that might be missed in manual testing.

Both manual and automated testing have their advantages and disadvantages, and the most effective approach will depend on the specific needs and constraints of the project. For instance, manual testing may be more effective for early-stage testing, where the application is still in development and requires constant feedback and iteration. On the other hand, automated testing may be more efficient for testing large-scale projects, where testing hundreds or thousands of scenarios and user interactions manually would be time-consuming and costly.

What are the challenges and misconceptions around testing for VR and AR products?

Quality assurance and testing of AR and VR applications present unique challenges and common misconceptions:

  • Limited device availability and compatibility: As AR and VR technology is still relatively new, there is limited availability of compatible devices and platforms. This can create challenges in testing the application across different devices and operating systems, resulting in a lack of consistency in user experience.
  • Lack of standards: Another challenge is the lack of industry standards for AR and VR applications. This means that there is no clear benchmark for quality, performance, or user experience, making it challenging to identify when an application is considered “good enough.”
  • Complexity: AR and VR applications are complex and require advanced technology and hardware. This complexity can make it difficult to identify and diagnose issues and bugs during testing, particularly when they involve the interaction between different hardware and software components.
  • Limited testing tools: There are limited tools available for testing AR and VR applications, particularly for automated testing. This can make it difficult to create comprehensive test scripts and identify issues quickly.

Final thoughts

AR and VR are disruptive technologies that impact, and will continue to impact, many aspects of both business and our personal lives. With the advent of new immersive experiences that are emerging all the time, there are different ways for ensuring quality, efficiency, and effectiveness. Innovative approaches to manual and test automation is critical for organizations attempting to deliver business and consumer products, services and content.

To ensure successful testing, it is important to consider the challenges and misconceptions around the specific needs to AR and VR products and develop effective testing strategies that ensures their success.
