In human–computer interaction, translating information between binary and numerical representations and human concepts remains an active research area aimed at bridging the gap while preserving the core meaning of the information. The field concerned with this transition, translation, and transformation of information is known as Human-Centric Computing (HCC). In this context, adopting a human-centered approach to information representation, such as categorization, grouping, and summarization through various forms of granulation, incorporates information into the paradigm of Granular Computing (GrC). This perspective on information processing and semantics in systems and programming has experienced continuous growth in both conceptual development and methodological interest.This paper investigates GrC research from 1990 to 2026, with a particular focus on the evolution of publications in the field. It begins with an overview of GrC, including a brief history and a discussion of its main techniques. Publications since 1990 are statistically analyzed and reviewed to identify common themes and research trends. In addition, selected research papers are examined under specific categories to provide further insights and discussion. This paper aims to highlight the evolution of GrC and identify potential future research directions.
