How can you design VR applications that are engaging and interactive, without sacrificing performance?

Use optimized 3D models and textures to keep things looking good but running smoothly. Design levels that are intuitive and guide players with visual cues. Use special effects like shaders sparingly to boost realism without draining resources. Employ dynamic loading to manage memory by loading only what’s needed. Include adjustable quality settings so users can tweak performance for their devices. Always test your app on various systems and use profiling tools to find and fix slowdowns.

1. Get to Know Your Users: Start by finding out what your users like and what they need. Talk to them, send out surveys, or watch how they use VR. This helps make sure the VR app is something they’ll enjoy and can use easily. 2. Understand Comfort Levels: Learn how long users can wear VR headsets without feeling tired or dizzy. Everyone is different, so it’s important to create a VR experience that doesn’t make users feel uncomfortable or sick. 3. Think About Accessibility: Remember that not everyone experiences VR the same way. Some users might have trouble with certain movements or might not be able to see or hear as well. Make sure your VR app has options for everyone to enjoy it. Try to counter motion sickness in your experience.

Understanding your users is a vital aspect to get right before undertaking any design work. Engage with your users and find out their goals and expectations of your VR project, how often they've used VR headsets in the past, how sensitive they might be to motion sickness and what kind of features they'd like to see.

Incorporating accessibility features has been incredibly beneficial in designing our VR applications. For example, we've introduced adjustable settings for users sensitive to motion sickness, such as dynamic field of view adjustments and teleportation movement options, significantly improving the comfort and inclusivity of our VR environments. These features not only cater to a wider audience but also demonstrate our commitment to creating an immersive experience that is accessible to users with varying levels of VR familiarity and physical comfort requirements.

I imagine you should Design it for user comfort: Implement comfort settings such as adjustable movement speeds, field of view options, and comfort vignettes to mitigate motion sickness and enhance user comfort. Use locomotion techniques like teleportation or room-scale movement that are less likely to induce discomfort.

VR typically can be quite exhausting if your users aren't used to the headsets, so optimising your experience for comfort and safety is vital. Reduce motion sickness as much as you can by utilising tricks such as 45° snap turning instead of continuous turning and using a vignette to focus on a certain area when turning.

Safety and comfort in medical XR aren't just checkboxes; they're our top priorities. Picture a patient navigating a virtual environment for the first time; their comfort is as important as the therapy's effectiveness. We take every measure to ensure the virtual world is a safe haven, from designing with empathy to prevent discomfort, to rigorously testing to avoid any potential health risks. By weaving medical expertise into every aspect of XR development, we aim to make these technologies a seamless, positive addition to healthcare.

Keeping an eye on texture resolution, baking in lighting, use less lights on the scene, keep the poly-count low on models to name but a few!

Create experiences that avoid causing motion sickness by maintaining a high, stable framerate and providing intuitive controls. It's important to design environments and interactions that feel natural and reduce the strain on the eyes and body. Offer customizable settings so users can adjust the experience to their comfort level. Regular breaks should be encouraged to prevent discomfort and fatigue. By considering the physical and mental well-being of the user, you ensure a pleasant and immersive VR experience.

Performance is arguably more important in VR than any other form of interactive application. Ideally, you want to run at at least 72hz (preferably 90hz or higher). Performance isn't just one thing and so planning early is important. You should continuously test your app to identify any performance bottleneck throughout your development process. Interactivity will bring you far more return on investment than realistic graphics. So go for performant graphics styles: lower poly count and simpler lighting models. Make limited use of transparency. If you are targeting the Quest set of devices you can potentially make use of Application SpaceWarp to increase performance. Finally, be wary of runtime memory allocation and garbage collectors.

Use techniques such as level of detail (LOD) management, where objects are rendered in higher detail when closer to the user and in lower detail when farther away, to maintain high performance. Implementing efficient asset streaming and culling techniques to only render what the user is currently looking at can also significantly improve performance. By optimizing content, you can create rich, interactive environments that run smoothly on a wide range of hardware.

I've heard from developers that I've worked with that they were able to increase performance by exporting GLB environments as a single object, rather than many multiple objects in a scene.

There are many different aspects to optimization. Most of these overlap with other 3D game optimizations. The basics are adding LODs, reducing textures, reducing draw calls (great for standalone devices!), and culling unseen models. Do not forget that the issue can also be in your code, which will put too much load on the CPU, rather than the GPU. For VR, the bottleneck usually is the GPU. It is important to optimize where it is needed. The biggest thing is to profile your project. This can be done with the Unity Profiler, Unity Frame Debugger, or runtime tools like renderdoc

Optimización de gráficos: Utilice técnicas de renderizado eficientes, como el culling de objetos que no están en el campo de visión del usuario, LOD (Level of detail) dinámico para reducir la carga de polígonos en objetos distantes y shaders simplificados. Reducción de la carga de texturas: Utilice texturas comprimidas y mipmapping para reducir el tama?o de los archivos de textura y la carga en la GPU. Gestión de memoria: Minimice la cantidad de memoria utilizada por la aplicación mediante la eliminación de recursos no utilizados y la carga de activos de manera eficiente bajo demanda. Optimización del código: analiza tu codigo, identifica y elimina ineficiencias, como bucles anidados innecesarios o asignaciones de memoria frecuentes.

Start by testing early versions with users to get feedback on how engaging and interactive your world is. Pay attention to how they interact with your VR world, what they enjoy, and where they have issues. Use their feedback to make changes and improve the world. It's a cycle: test, gather feedback, then tweak and improve. This process helps you to refine interactions, improve engagement, and ensure that the app runs smoothly on different devices. Frequent testing also helps catch performance issues early, so you can optimize as you go rather than trying to fix problems at the end.

Testing, especially in the new world of spatial computing, is paramount. The fun thing about VR experiences is that everyone is looking for a new thing to try. We're still at a point where even the simplest interaction is unique and engaging, but you want to make sure that the platform can handle the improvements, upgrading and user suggestions. What I have learned over the years is that users have more ways than ever to interact with Devs. There's no shortage of testers or feedback - but be prepared to take it all in stride. Stay on the path when you believe it's the right way to move, and take suggestions when you believe it's an improvement. Don't fall into the trap of meeting every user's recommendation after testing.

Test your projects, and test early! The first thing to do in a new project is not to add content, it is to test on the device you want to work with! If this does not work, any time spent in the project will just make it more complicated to fix the issue. After that make at least 1 test for design and performance after a major addition to the project. Especially if these additions add new features, which are not tested beforehand. Documenting these test results also can benefit you by having performance overviews and design improvements throughout the project

We began by minimizing latency, improving responsiveness, and tackling motion sickness by optimizing code execution and reducing unnecessary processing overhead. Asynchronous loading became our trusted ally, preventing frame rate drops by loading large resources during runtime.

Push boundaries by trying new interaction models or storytelling techniques. Mix physical movements with virtual for a sense of presence. Use voice, gaze, and gesture controls to see what feels most natural. Explore multiplayer experiences to add a social dimension. Constant innovation keeps users engaged and can lead to breakthroughs in how we experience virtual worlds. While experimenting, keep performance in check by monitoring how new features affect the VR app's smoothness and response. This balance of innovation and performance is the sweet spot for successful VR applications.

Focus on creating immersive environments that captivate user's attention while maintaining optimal performance . Utilize spatial audio, dynamic lighting, and environmental effects to enhance immersion without overburdening the hardware. One must pay attention to small details and environmental cues that contribute to the overall sense of immersion. Enrich the virtual world with realistic objects, textures, and animations that evoke a sense of familiarity and believability, enhancing the user's sense of presence and immersion.

Especially in VR/MR there are many ways around problems. We are far from having discovered all methods to work with VR hardware. This is both on the design side, where you can guide your users differently through an experience. This could change the user flow to keep the same design elements, while having them in more performant areas. There also are new and innovative methods to optimize for VR. Use Multipass/single pass instanced rendering, (eye tracked) foveated rendering, application spacewarp on standalone devices, late latching, variable rate shading, and so much more. Give a look at these new developments and see if your project can benefit!

Take the highest-rated VR experiments. Break each one down into its smallest components to understand why they are highly successful in terms of performance, 'wow' factor, educational value, accessibility, other aspects. Create a mind map to organize and visualize these elements. Identify which of these elements align with the experience you aim to build. Test these elements within your experience one at a time. Be selective and don't try to incorporate them all in your project.

What I've been focusing on to build engaging yet efficient VR experiences, is adding gaming elements. Interactive challenges, rewards, and storytelling can enhance user engagement without straining the system. Incorporating features such as leaderboards and achievements encourages users to spend more time in the app without compromising its performance. Gamification not only makes the VR experience more fun and engaging, but it will also give users an incentive to continue to come back.

Favorisez des gestes et des mouvements naturels, alignés sur le comportement humain quotidien. Par exemple, si votre application nécessite des sélections ou des manipulations, envisagez des gestes familiers comme le pincement ou le glissement. Cette approche simplifie l'expérience utilisateur en créant une symbiose entre les actions virtuelles et les réflexes humains, réduisant ainsi la charge cognitive. En concevant des interactions basées sur la nature humaine, vous contribuez à une expérience immersive où l'utilisateur se sent connecté intuitivement à l'environnement virtuel, créant ainsi une interface qui semble naturelle, voire invisible.

i think highlighting the role of ethical consideration and some morality points such as improving privacy and data security is effective too, and I belive AI and ML will be gamechanger. Using AI and machine learning in VR makes virtual worlds smarter and more suited to what different users like. AI helps create changing environments that respond to what users do. Machine learning makes VR adjust to users' likes by noticing how they behave and changing the VR world for them. This makes VR more real-feeling, easy to use, and fun, leading to new ways we experience digital worlds.
