Inspiration
Echoes explores guidance beside everyday work, so useful instructions stay near the task instead of on a phone.
What it does
The working Lens Studio desktop Preview prototype is a seven-step spatial brick-building guide for the lower assembly of LEGO 40897, covering 17 incoming pieces. Separated parts, cyan final-position ghosts and insertion paths explain connections. Users can turn or orbit the model, switch top and underside views, zoom, return Home, and inspect individual joints. "I placed it" records manual confirmation and advances. Back preserves progress; Restart clears it.
How it was built
Built using Lens Studio, CLAD, Lens Studio MCP, Spectacles Interaction Kit and UI Kit. The public repository includes the Lens Studio project, design brief, run instructions and validation evidence. LDraw geometry uses CC BY 4.0 with attribution and modifications documented in the repository. Snap packages retain their own terms.
Challenges and learning
The project focuses on consistent model views, joint inspection and progress tracking. Guide-specific tests passed 24/24 control and 79/79 step-flow checks, covering all 17 joints. Source checks passed 29/29; a seeded state stress test completed 50,000 actions without failures. The work demonstrates the need to explain connections from useful angles, preserve the user's place, and distinguish automated Preview validation from real-device testing.
Prototype limits and next steps
The video uses actual desktop Preview footage with injected input for the demonstration sequence. Conceptual overlays illustrate a future wearable experience. Echoes does not see or verify physical bricks. Mouse interaction is a Preview stand-in; real hand tracking, physical fit and headset comfort are unverified. Peripheral placement, voice or gaze activation, task recognition and physical-placement verification are future possibilities, not implemented features.
