System Instructions & Design Rules: > Create a highly detailed, 15-slide technical academic presentation for a project named "AuraBlend." > CRITICAL DESIGN REQUIREMENT: The strict color palette for every single slide must be Mocha Brown, Platinum Silver, and Pale Lavender. Apply this custom theme globally to backgrounds, text, and visual accents. > LAYOUT RULE: Do not use long paragraphs. The layout must be highly professional and scannable, using crisp, technical bullet points (maximum 6 bullets per slide, roughly 30 words each).

Created using ChatSlide
AuraBlend addresses the pressing issue of privacy leaks during video calls by offering a hardware-free spatial privacy solution. Utilizing a gesture-controlled interface, it maintains authentic room aesthetics. The architecture employs a robust technology stack including Python, OpenCV, and YOLOv8, featuring a five-stage pipeline for real-time skeletal hand tracking. Validation results demonstrate effective performance at 30 FPS with OBS routing. Future directions include enhancing...
