Designing For VR

Designing user interfaces for emerging technologies like virtual and augmented reality headsets presents unique challenges compared to traditional desktop and mobile interfaces. VR/AR places the user in a fully immersive 3D environment surrounded on all sides, requiring interfaces optimized for new interaction methods and sensory perceptions. As designers create experiences for next-gen headsets like Apple Vision, several technical differences must be accounted for.

Immersion and Presence

One of the primary design goals in VR is immersion – how thoroughly the user feels present in the virtual world. On headsets, the display fills the entire field of vision, granting a heightened sense of presence. However, this comes with motion sickness risks if the VR content is not smooth and responsive enough. Designers must optimize framerates, image quality, latency, and motion controls to avoid discomfort. Interfaces need to feel intuitively integrated with the environment instead of breaking the user out of the experience. Subtle notifications versus intrusive pop-ups better support immersion.

Spatialization of Interactions

In VR, users can look in any direction and interact with their environment by moving their head, hands, or full body. Interfaces need to match this spatial nature. 2D flat screens or panels placed in space may conflict with presence. Instead, consider interactions that make use of the entire 360-degree space, like guiding the user’s hands to virtual objects or gestural menus that appear where needed. Spatial audio further enhances the directions interfaces can provide feedback from. Proper use of spatialized interactions keeps interfaces feeling like natural extensions of the virtual world.

Accounting for Non-Traditional Inputs

Headset displays preclude traditional input devices like mice and keyboards. Interfaces must support innovative methods like motion controllers, gaze tracking, gestural controls, and voice commands. Each of these has affordances and limitations that designers should leverage. For example, gestural menus can provide quick selectable options while avoiding occluding the view, but they may require visible feedback on the selection state. Motion controllers enable direct manipulation but have fatigue tradeoffs. Supporting multiple complementary inputs allows tailoring interactions to each user’s preferences and needs.

Embracing Emergent Form Factors

While current VR headsets resemble goggles worn on the face, future form factors may diverge into new possibilities. AR smartglasses or direct brain-computer interfaces could eliminate screens entirely. Designing flexible, context-aware interfaces adaptable to unexpected changes in technology ensures experiences last beyond any single device. Core interaction patterns and information architecture principles remain important to carry over between form factors while surface designs evolve.

Consistency despite Lack of Shared Standards

Fragmentation exists across VR/AR platforms as no dominant standard has emerged like with mobile. Designers build experiences targeted to specific hardware without guarantees of portability. Maintaining design consistency despite this allows for the delivery of quality even when users own different headsets.

Consistency in conceptual models, control schemes, and core navigational paradigms helps onboard new users regardless of technical variations between platforms. Design systems that separate content from their presentation enable flexibility.

In conclusion, effectively designing user experiences for VR/AR headsets requires embracing challenges like comprehensive immersion, spatial interfaces, alternative inputs, and uncertainty in standards. Optimizing for the strengths of these new technologies while avoiding discomfort creates engaging, intuitive products that fulfill the promise of next-generation platforms. With a user-first approach, VR/AR interfaces can feel like extensions of their virtual worlds.
