Line Drawing Recognition AI Agent:

Enable a kid‑focused AI game to recognize and guess user drawings in real time, identifying shapes and character sketches as players draw—thereby creating an engaging, responsive, and delightfully interactive play experience.

​

Solution:

Implemented a custom GenAI–powered recognition agent that interprets line drawings and predicts the intended object or character during gameplay.

• The model stack leverages Stable Diffusion and LoRA components for strong visual representations and efficient fine‑tuning on sketch‑style data, improving robustness to varied drawing styles and partial inputs.

• Deployed as a low‑latency service integrated with the game client, supporting streaming inference (progressive guesses as the drawing evolves) and confidence scoring to drive in‑game hints, feedback, and difficulty adjustment.

 

Benefits:

• High player engagement: Instant “guess‑as‑you‑draw” responses make play feel smarter and more rewarding, boosting session length and repeat play.

• Robust accuracy across styles: Representation learning with Stable Diffusion plus LoRA fine‑tuning improves recognition of messy, partial, or childlike sketches.

• Low latency at scale: Optimized inference enables smooth gameplay on typical consumer devices and cloud backends.

• Rapid iteration: Modular training pipeline makes it easy to add new categories or characters and to adapt difficulty using confidence thresholds.

• Operational efficiency: Reusable model components and fine‑tuning workflows reduce ongoing maintenance and content‑update effort.
