Enhancing Elderly Leisure Experience Through Innovative VTuber Interaction in VR with ChatGPT

This research introduces an innovative approach that integrates a virtual character in a virtual reality setting using ChatGPT as a conversational artificial intelligence system. The program was developed using a programming language and leveraged the Unity game engine's built-in support for virtual reality and natural language processing. In this approach, users engage with the virtual character through natural language conversations, and ChatGPT generates the responses. A study was conducted with individuals living alone to assess the effectiveness of this approach, which yielded promising results in enhancing the user experience of conversational agents within the virtual reality context. The research findings indicate that experiential value significantly influences perceived ease of use and perceived usefulness, and these factors, in turn, impact the intention to use. Therefore, the experience of AI VTuber can provide a sense of leisure and entertainment for the elderly. Designing an innovative VTuber integrated with ChatGPT interaction in virtual reality offers a simple and useful interaction model that can provide a novel experience for the elderly, enhancing their leisure and entertainment experiences while promoting their physical well-being.
