Design And Implementation Of Chat System For Elderly Virtual Reality Application

With the breakthrough of 5G and Internet technology,virtual reality applications are gradually moving to the stage.At the trend of the aging population in the world,their spiritual life will become an important social issue.The products designed for the elderly will also have huge market and value.For the elderly,the simplified and intelligence of the interaction will be the top priority in product design.Based on this,a chat system based on handle and voice interaction in virtual reality application is proposed.To design such a fully functional system,it analyzes three demands of users,the docking requirements with the virtual reality application scenarios,simplify the interaction needs of the elderly users,and meet the emotional sustenance and friend needs of the elderly.After the requirements,the architecture of the system was built,and the functional modules were designed.The system is divided into client,server and hardware.The client uses the Unity platform for design and development.The framework of the chat system is built with the GameLink SDK from cloud.The server uses the SSH framework.The background database is MySQL for storing data information.The hardware includes a handle and a walker,and communicates with the client by using Bluetooth.The voice interaction part uses the API of the IFLYTEK to perform voice recognition,search keyword and compares the library.The system is divided into user information module,friend module,voice chat module,voice recognition module and handle control module.The article has designed and implemented these modules in detail,and gives test cases and results for the system.We can see from the result that the system can meet the requirements of basic handle control and voice interaction and run stably.Users can perform voice chat and operate friends,the system can connect existing project users and integrated into virtual reality applications.The system achieve the desired design goals and can small-scale trials and promotion in hospital rehabilitation centers and nursing homes.
