Insights & Lessons

Interface Design Philosophy

This experiment highlights the important distinction between technologically impressive interfaces and practically useful ones. While hand tracking creates compelling demonstrations, the absence of tactile feedback and precision control limits real-world applicability.

Development Velocity

The rapid prototyping capability enabled by AI assistance allows for quick exploration of ambitious interface concepts, making experimental UI development more accessible.

Future Considerations

VR/AR contexts may provide better frameworks for gesture-based interfaces where the lack of traditional input methods creates different usability trade-offs.
