배경 및 목적: 증강현실은 가상현실과 구별되는 개념으로 가상세계를 현실세계에 중첩시켜 상호작용하게 하는 기술이다. 최근 언어치료 분야에서도 증강현실은 전통적인 치료 패러다임을 보완하기 위한 새로운 매체로서 관심 있게 다루어지고 있다. 본 연구에서는 태블릿 기반의 마크리스(markless) 증강현실 언어치료 프로그램을 개발하고 증강현실과 그림카드를 이용한 중재의 효과를 비교하고자 하였다. 방법: 증강현실 애플리케이션은 자연특징 추적 알고리즘을 이용하여 객체를 인식하게 프로그래밍하였으며, 단순언어발달지연 아동 3명에게 교대중재설계를 사용하여 24개의 동작동사에 대하여 증강현실과 그림카드 기반 중재를 시행하였다. 두 중재 간의 차이는 어휘정확도, 중재효과 크기, 몰입도, 학습 흥미도로 비교하였다. 결과: 태블릿 기반 증강현실 중재와 그림카드 중재 모두에서 동작동사 어휘력의 향상을 나타내었으며 중재와 유지 단계에서 증강현실 기반 중재가 더 높은 어휘정확도를 나타내었다. 학습몰입은 증강현실 기반 중재가 더 높게 나타내었으며, 일반적 흥미는 두 중재 모두 유사한 결과를 보였으나 상황흥미에서 증강현실 기반 중재가 더 높게 나타났다. 논의 및 결론: 증강현실과 그림카드 중재 모두 효과적이었으나 증강현실 기반 중재는 기존의 그림카드로 제한이 있었던 어휘들의 학습에 효과적이었으며, 혼합현실의 제공은 아동의 학습동기와 참여를 향상시키는 데 도움이 되었다. 또한, 마크리스 증강현실 플랫폼은 콘텐츠의 확장이 용이하여 임상현장에서 증강현실 기반 언어치료 프로그램의 적용에 유용하게 활용될 수 있을 것으로 사료된다.
영문 초록
Objectives: In the field of speech language therapy, augmented reality (AR) is being treated with interest as a new medium to complement the traditional therapy paradigm. The purpose of this study was to develop a program for markless AR-based speech language therapy using tablets and to compare the effects of AR and picture card intervention. Methods: AR applications were programmed to recognize objects using natural feature tracking algorithms, and 3 children with specific language impairment participated in AR and picture card-based intervention with 24 action verbs in an alternating treatment design. The differences between the two interventions were compared in vocabulary accuracy, improvement rate difference, flow, and learning interest. Results: Improvement in action verb vocabulary was shown in both the AR-based intervention and the picture card intervention, with the AR-based intervention resulting in higher vocabulary accuracy in the intervention and maintenance phase. Additionally, the AR-based intervention showed higher learning flow. General interest was similar in both intervention methods, but the AR-based intervention was higher in situation interest. Conclusion: AR-based intervention was effective for learning vocabulary that would normally be taught with conventional picture cards; mixed reality AR helped improve children’s learning motivation and participation levels. In addition, the markless AR platform has advantages for clinical speech language pathology practice because the content can be easily expanded.
