In the context of XR, an interface refers to the point of interaction and communication between a user and the XR system. It serves as the intermediary platform through which a user engages with the virtual or augmented environment. It contains various elements and components such as visual, auditory (sometimes haptic) interactive elements, that facilitate the exchange.
The interface is a critical component that enables the navigation, manipulation and immersion in the virtual or augmented world. On the hardware side, we have components such as headsets, controllers, sensors and display devices, while the software components include user interfaces, menus, spatial mapping and gesture recognition systems. The design and functionality of the interface significantly influence the user’s ability to perceive and interact with the XR environment effectively.
A user-centric approach to interface design in XR is about tailoring the interface to align with human cognitive capabilities, preferences and ergonomic considerations. It focuses on optimizing the interface for intuitive interactions, minimizing cognitive load and ensuring a seamless and engaging UX. A good user-centric interface design is intuitive, accessible and comfortable — and it is the defining element of a successful virtual environment.
This article discusses the essence and the main principles of the user-centric approach that serves articulation of best practices for designing an XR landscape.
Why User-Centric Design?
User-centric design places paramount emphasis on tailoring systems and interfaces to harmonize with the user’s cognitive, perceptual and ergonomic proclivities. It is ultimately based on human behaviors, preferences and their limitations to create a cognitive design that is aligned with mental models. The essence of user-centric design lies in focusing on user experience — how useful, efficient and overall satisfactory it is.
It carries a particular significance in XR, because interactions are the core and the basis of how this technology will be working. It considers sensory apparatus and psychological predispositions, as it needs to ensure a type of interaction that is natural and instinctive. If these criteria are not met, the product cannot serve its purpose, and therefore is rendered useless (or very uncomfortable to use). The interface must be crafted to optimize the cognitive load and allow an easy transition between the physical and digital worlds, which should not be causing any discomfort or distortion.
But it goes beyond the UX. The interfaces act as a linchpin in the widespread adoption of XR, because their quality determines if the interface mitigates the barriers to entry for users, reduce the learning curve and instil confidence in interacting with immersive systems — which is especially true for first-time users. If it is easy, comfortable and intuitive, it will propel broader acceptance across diverse user demographics and professional domains. The ecosystem can only be an ecosystem if it is democratized and accessible to everyone.
