Research on emotion animation generation based on AIGC tools: Personalized expression and multi-level encoding strategy.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study targets the problems of poor semantic consistency and inadequate control over personalized expression in emotion animation generation. Its goal is to develop an automated generation framework that combines multi‑level semantic recognition with style adjustment functions, thereby enhancing the semantic building system and human‑computer interaction paradigms of AIGC technology for controllable emotional animation. Utilizing ChatGPT's NLP capabilities and Runway ML's techniques for generating dynamic images, we construct a hierarchical prompt structure and adopt a three‑dimensional encoding strategy, which allows structured interpretation and coordinated mapping of emotional, behavioral, and stylistic information. The experimental results demonstrated that the proposed method could stably generate animations with coordinated consistency among facial expressions, motion rhythm, and color semantics under various emotion-driven conditions, while exhibiting reasonable temporal progression characteristics. In personalized generation, distinct user profiles produced significant differences in dimensions such as expression amplitude, motion rhythm, and stylistic features, reflecting the model's fine-grained control over multidimensional generation parameters. In the validation of the encoding mechanism, the integration of hierarchical prompts with the multi-level encoding strategy significantly enhanced the naturalness of facial expressions, the logical coherence of movements, the continuity of temporal sequencing, and the precision of micro-action depiction, thereby reinforcing the intensity and realism of emotional presentation. This work develops a framework for generating emotional animations that combines semantic layering with adaptive personalization. It offers methodological backing for the structural optimization and interactive enhancement of AIGC systems within the realm of high‑quality visual content production.
