Abstract

In immersive virtual environments including mixed reality (MR) and virtual reality (VR), avatars or agents, which are virtual humans, are being studied and applied in various ways as factors that increase users' social presence. Recently, studies are being conducted to apply generative AI as an agent to improve user learning effects or suggest a collaborative environment in an immersive virtual environment. This study proposes a novel method for interface application of a virtual assistant agent (VAA) using OpenAI's ChatGPT in an immersive virtual environment including VR and MR. The proposed method consists of an information agent that responds to user queries and a control agent that controls virtual objects and environments according to user needs. We set up a development environment that integrates the Unity 3D engine, OpenAI, and packages and development tools for user participation in MR and VR. Additionally, we set up a workflow that leads from voice input to the creation of a question query to an answer query, or a control request query to a control script. Based on this, MR and VR experience environments were produced, and experiments to confirm the performance of VAA were divided into response time of information agent and accuracy of control agent. It was confirmed that the interface application of the proposed VAA can increase efficiency in simple and repetitive tasks along with user-friendly features. We present a novel direction for the interface application of an immersive virtual environment through the proposed VAA and clarify the discovered problems and limitations so far.

본 연구는 혼합현실과 가상현실을 포함하는 몰입형 가상환경에서 OpenAI의 ChatGPT를 활용한 가상 보조 에이전트의 인터페이스 응용에 관한 새로운 방법을 제안한다. 제안하는 응용 방법은 사용자의 질의에 응답하는 정보 에이전트와 사용자의 요구에 맞춰 가상 객체, 환경 등을 제어하는 제어 에이전트로 구성된다. 이를 위해, Unity 3D 엔진, OpenAI, 그리고 가상현실과 혼합현실 사용자 참여를 위한 패키지 및 개발 도구를 통합하는 개발환경을 설정한다. 그리고 음성 입력으로부터 질문 쿼리에서 답변 쿼리, 또는 제어 요구 쿼리에서 제어 스크립트로 생성으로 연결되는 작업 흐름을 설정한다. 이를 기반으로 혼합현실, 가상현실 체험 환경을 직접 제작하고 에이전트의 성능 확인을 위한 실험을 정보 에이전트의 반응 시간, 제어 에이전트의 정확도로 나누어 진행하였다. 결과적으로 제안하는 인터페이스 응용을 통해 사용자 친화적이고 단순하고 반복적인 작업에서의 효율을 높이는데 유용할 수 있음을 확인하였다. 우리는 새롭게 제안하는 인터페이스를 통해 몰입형 가상환경에서 인터페이스로의 응용에 관한 새로운 방향성을 제시하고 발견된 문제점과 현재까지의 한계점을 분명히 밝힌다.
