The AI pipeline behind clear, expressive and scalable HKSL experiences.
THE IMPACT AI TECHNOLOGY

Where language becomes movement.

Our technology combines LLM intelligence, HKSL grammar, motion capture and a generative 3D avatar engine. Together, these layers turn everyday digital content into accessible sign-language video.

A language-first pipeline for real-world communication.

AI PIPELINE

From input to an expressive 3D signer.

The LLM learns from text and audio, while the HKSL database, motion references and avatar engine turn that understanding into visual language.

01
UNDERSTAND

LLM & AI Pipeline

Text, audio and video are interpreted by our multimodal AI pipeline. Domain fine-tuning gives the model the vocabulary and context it needs to understand HKSL-related content.

02
STRUCTURE

Grammar Correction

The language layer reorganises meaning into natural HKSL grammar instead of translating word by word. This preserves sentence structure, context and signing order.

03
CAPTURE

Motion Capture

Reference signing data and high-definition video capture the movement, timing and expression needed to communicate the translated sequence clearly.

04
GENERATE

3D avatar Engine

The HKSL AI engine maps language and motion onto a controllable 3D avatar, producing consistent, reusable signing content at scale.

05
DELIVER

Accessible Video

The final signing video can be delivered through websites, apps, documents and public-service experiences wherever people need access to information.

THE KNOWLEDGE LAYER

HKSL database

The database is the bridge between AI understanding and natural signing. It brings together HKSL vocabulary, grammar patterns, 3D model data, high-definition video and curated signing references.

  • Language dataSigns, phrases, grammar and domain terminology.
  • Motion dataTiming, hand shape, facial expression and body movement.
  • Model dataFine-tuned LLMs and controllable 3D avatar parameters.
