A Salvadoran lab is building camera-based tools for hands, bodies and sign language
Zero Day Labs presents three projects that use ordinary cameras for gesture-controlled 3D, body movement analysis and a LESSA sign-language translator.
- For
- LESSA users and Salvadoran deaf communities
- Worth noticing
- The LESSA translator is described as covering the full alphabet, including moving letters, plus numbers 0–10; it is in validation.
Field notes
The lab groups three camera-based projects: Handviewer manipulates 3D objects with hand gestures; HumanViewer estimates posture and movement; and the LESSA project describes sign-to-text-and-voice output. Their stated stages differ—internal development, prototype, and first version under validation—so the page is a snapshot of an early portfolio, not evidence of finished public tools. Handviewer is described as running in the browser and offline; HumanViewer is also described as working without internet.
