Showcase 2.0 Features / 4. Hand Tracking and Controller Support
Time Estimate
100 Hours
Summary
Hand Tracking and Controller Support forms the foundation for intuitive interactions within Showcase 2.0. This epic ensures precise, seamless interaction with objects and interfaces, accommodating both hand-tracked and controller-based input for maximum accessibility and user comfort.
Key Goals
- Enable accurate and responsive interaction through hand tracking and controllers.
- Provide multiple input methods to ensure flexibility and accessibility for all users.
- Integrate haptic and visual feedback to enhance user interaction with objects and interfaces.
Responsibilities
- Develop grabbing and selecting mechanics optimized for hand tracking and controllers.
- Implement near-field and far-ray-based interaction for UI and object manipulation.
- Enable locomotion through teleportation and smooth movement mechanics.
- Integrate spatial joysticks for specific features like excavator operation.
- Provide consistent feedback mechanisms (audio, visual, and haptic) to guide user interactions.
Acceptance Criteria
- Grabbing, selecting, and object manipulation functions smoothly with both hand tracking and controllers.
- Teleportation and smooth movement options are functional and meet user comfort standards.
- UI elements respond to both near-field and far-ray-based interactions.
- Spatial joysticks support intuitive and precise interaction during use cases like operating virtual machinery.
Risks and Mitigations
- Risk: Inconsistent behavior across different hand tracking hardware.
Mitigation: Standardize interactions and test thoroughly on all supported devices.- Risk: User discomfort during smooth movement.
Mitigation: Include comfort options like tunneling and snap-turn to reduce motion sickness.
Success Metrics
- High user satisfaction with hand tracking and controller interactions during testing.
- Achieve consistent performance benchmarks across all supported hardware.
- Reduced user-reported issues related to interaction mechanics by 90% post-launch.
