Multimodal World Memory: Integrating Audio, Haptics, and Language into Open-Source World Models

TL;DR: What if LingBot-World could not only "see" but also "hear," "feel," and "converse"? Integrate audio, haptic feedback, and language as first-class citizens into the world model, creating richer simulations for agents and users. The first experiment: Extend LingBot-World to include synchronized audio streams and text-based agent communication, then measure gains in agent learning efficiency and realism.

Research Question: Can extending video-based world models with multimodal inputs and outputs (audio, haptics, language) improve agent learning, interactivity, and simulation realism in open-source environments?

Hypothesis: Adding synchronized audio, haptic, and language modalities will enhance both agent training (e.g., faster policy convergence, better generalization) and user experience (e.g., immersion, usability), especially in scenarios where visual cues are insufficient.

Experiment Plan: - Extend LingBot-World's data pipeline to collect and align audio (environmental sounds, speech), haptic signals (e.g., force feedback in simulated robotics), and textual dialogues.

• Retrain or fine-tune the world model to generate and respond to multimodal signals.
• Compare agent learning (e.g., in navigation or manipulation tasks) and user-reported realism/immersion with and without multimodal inputs.
• Analyze performance on multimodal benchmarks, e.g., AVE (Audio-Visual Event), and new user studies.
