【Unite 2017 Tokyo】EditorVRの設計から学んだこと：使えるVRエディターのためのデザイン
2 likes949 views
The document discusses the development of an open-source EditorVR package for Unity, which allows users to design in virtual reality while addressing various UI and UX challenges. Key hurdles include creating tools for editing in edit mode and ensuring functionality across different controllers and scales. It also highlights the need for intuitive user interactions and constraints in object manipulation to enhance the VR experience.
【Unite 2017 Tokyo】EditorVRの設計から学んだこと：使えるVRエディターのためのデザイン
- 4. EditorVR • Open-source package you add to your project • Extensible; you can add functionality to it • Runs in edit mode, so your changes are saved • Available for Vive or Rift • Requires controllers and a PC • Just updated to Unity 5.6, but requires a custom build until our input system is finished
- 6. Key hurdles • Creating inside Unity in Edit Mode • Designing a robust creation tool • Key UI + UX pain points
- 7. Creating inside Unity in Edit Mode • Unity itself does not run in realtime, but we need to render the scene view in realtime. • Can’t use the GPU to select objects. • Can’t use onCollision to select objects in a scene; no physics in edit mode.
- 8. Creating inside Unity in Edit Mode • Can’t edit the user’s scene (so can’t add colliders). • Can’t scale the world; have to scale the user.
- 11. Creating inside Unity in Edit Mode • Miniworld is a re-render of the scene from a different perspective, preserving the existing z- buffer. • Play mode is very different in VR; it takes up all of the input.
- 12. Key hurdles • Creating inside Unity in Edit Mode • Designing a robust creation tool • Key UI + UX pain points
- 13. What is a robust tool? • Work for every type of scene. • UI shows up on any kind of color scheme and lighting scheme. • Must work consistently across controller types. • Works with any scale of asset. • Does not limit the developer.
- 14. Designing a robust creation tool • Render queues
- 16. Designing a robust creation tool • Render queues: 9000+. • Gizmo interaction: different than 2D. • Anisotropic filtering is needed for everything. • Keyboard inputs: brand new.
- 17. Key hurdles • Creating inside Unity in Edit Mode • Designing a robust creation tool • Key UI + UX pain points
- 18. Key UI + UX pain points • Introducing the concept of tools • Tool switching.
- 21. Key UI + UX pain points • Introducing the concept of tools. • Tool switching: how to teach people? • Gestures: mentally & computationally taxing. • UI: HUDs are terrible. Want it accessible but not in the way. • Periphery is not useful for many interactions.
- 23. Key UI + UX pain points • Animations seem gratuitous, but are necessary. • Users really don’t see things. • Show what’s going to happen, what is happening, and what just happened. • Show as much of the controller’s real buttons in your model as you can.
- 24. Object interaction • Ultimate freedom is not so great. Use rotation constraints.
- 27. Object interaction • Ultimate freedom is not so great. Use rotation constraints. • User want to interact with all objects, even if they’re blocked. • But not in the same way: close objects should be more responsive, and far objects should be more forgiving.
- 28. Other surprises • Locomotion: fast, precise, won’t make you sick: pick two. • Sounds need to be predicted. • Double-clicks need to be slower. • Users don’t know if they’re inside a large object. • Must filter controller noise from user movement more than the tracking system.
- 29. How to start playing around with EVR • Have a Vive or Rift • Recommend a 1080 or higher • https://github.com/Unity-Technologies/EditorVR/ • http://rebrand.ly/EditorVR-build • Put package in project • Window > EditorVR
- 30. Add GDC video
