Showcase 2.0 Features / 4. Hand Tracking and Controller Support / Grab Mechanics
Time Estimate
20 Hours
Summary
Develop intuitive grabbing mechanics that allow users to interact with objects using hand tracking or controllers, ensuring precise and responsive interactions across all scenarios.
Key Goals
- Provide users with natural and accurate grabbing functionality for both hand tracking and controller inputs.
- Ensure grabbing mechanics support a wide range of objects and interaction scenarios.
- Integrate grabbing seamlessly with other interaction systems, such as tutorials and training modules.
Responsibilities
- Design and implement grabbing mechanics that work with hand gestures and controller inputs.
- Optimize interactions for precision and responsiveness across supported hardware.
- Test grabbing mechanics with various object types and scenarios to ensure compatibility and reliability.
- Align mechanics with training modules to provide consistent interaction standards.
Acceptance Criteria
- Users can grab and manipulate objects accurately using both hand tracking and controllers.
- Grabbing mechanics are responsive and intuitive, with minimal latency.
- All interactions integrate seamlessly with training modules and scenarios.
Risks and Mitigations
- Risk: Grabbing mechanics feel inconsistent or unreliable across different hardware.
Mitigation: Standardize mechanics and conduct thorough testing on all supported devices.- Risk: Users struggle to understand or execute grabbing gestures.
Mitigation: Provide clear visual feedback and align mechanics with established UX principles.
Success Metrics
- 95% of users report grabbing mechanics as intuitive and reliable during testing.
- Grabbing success rates exceed 90% across all supported hardware.
- Interaction-related support requests decrease by 20% after implementation.
