(I) General Requirements

To provide testers with a comfortable and relaxed scenario for upper limb rehabilitation training, the system uses 3D VR technology to realistically simulate two training environments: a high-end hospital room and a home living room. Users can interact within the scene using VR devices and eye-tracking equipment, such as moving positions and selecting tasks. The hospital room scene should have a space of no less than 30 square meters and a height of no less than 3 meters. It must include a large-screen (80-inch) TV and a virtual chair. The TV screen is used to display interactive content with the user, and the virtual chair corresponds to the real chair, allowing the user to sit and complete tasks, which include six upper limb rehabilitation training movement postures. The home living room scene should also have a large-screen (80-inch) TV, as well as furniture and appliances such as a sofa. The material representation in the scene should be realistic, with authentic surface textures and lighting that simulates a real environment.

(II) Functional Technical Requirements

(1) The system must have a login function. Before testing, users need to log in to the system so that test results can be recorded correspondingly for different users.

(2) The system must provide a training count setting function, allowing the test process to be repeated for the set number of training sessions.

(3) Scene selection function: Provide users with the ability to choose the test environment scene: hospital room or living room.

(4) After the test is completed, the system should prompt "End and Return" or "Retest."

(5) Result recording function: The system must synchronously record various test data and corresponding timelines in real time during the testing process.
