복합적 의사소통요구를 가진 개인의 사법접근권 강화를 위한 법률용어 AAC 상징 제작 가이드라인 개발 및 내용타당도 검증

Purpose: Individuals with complex communication needs (CCN) are vulnerable to marginalization within the legal system. Augmentative and alternative communication (AAC) can serve as a vital means to address this issue. This study was conducted as a preliminary step towards creating AAC judicial symbols to ensure access to justice for people with communication disabilities, by developing and validating a symbol design guideline. Methods: Forty-seven adults without disabilities were asked to draw representations of 15 judicial vocabulary items. A modified version of the symbol analysis framework proposed by Patel et al. (2007) was used to analyze and identify the visual features of these drawings. Commonly observed visual elements were categorized into eight domains, and detailed guidelines were proposed. These guidelines were then reviewed, revised, and finalized through a content validity assessment conducted by AAC experts. Results: Analysis of the drawings revealed that the most frequently applied visual features were ‘connectedness’ from gestalt principles, ‘exemplification’ from semantic property principles, and ‘singularity’ from constructive distinction principles. Detailed design guidelines for the AAC judicial symbols were derived across eight pictorial element domains: person, action, place, object, emotional expression, color, emphasis and contrast, and additional information. The final guideline was established following expert validation. Conclusions: To enhance iconicity of AAC judicial symbols, the visual characteristics of judicial vocabulary were systematically analyzed and understood. The resulting guideline provides a useful tool for symbol development aimed at strengthening access to justice for individuals with CCN. Future research should further validate the guidelines and symbols across diverse populations and continue the development of vocabulary and symbol systems to support the legal rights of individuals with CCN.
