The invention discloses an immersive robot teleoperation master-slave system and method based on bidirectional force sense mapping. The system comprises a master hand controller and a slave end robot, wherein master-slave position-force bidirectional closed-loop control is established through a wireless communication mode; the master hand controller sends a mechanical arm target pose instruction, an execution tail end closing / releasing instruction and a control signal of the mobile platform to the slave end robot to form a forward control channel; the control panel obtains feedback torque based on the current I fed back by the slave end robot and a preset torque coefficient Kt, and the feedback torque serves as force sense feedback of the slave end; the control panel sends a torque resisting instruction to the feedback motor according to the feedback torque, the feedback driving motor rotates according to the torque resisting instruction, the feedback transmission mechanism is driven to act, and a reverse feedback channel is formed. According to the invention, the action of the operator can be accurately mapped to the slave end robot, and the force generated by interaction between the slave end robot and the environment can be truly fed back to the operator in a low-delay manner.

This invention provides a human-computer interaction guidance method, comprising: acquiring the user's gaze information and hand information, and converting them into coordinates in the same screen coordinate system; calculating the eye-hand coordination distance, hand position stability, and hand movement trajectory tortuosity based on the coordinates within a predetermined time window; identifying whether the user is in a state of confusion or hesitation regarding screen interface elements based on the judgment results of the eye-hand coordination distance, hand position stability, and hand movement trajectory tortuosity; and actively triggering and displaying interactive guidance information at the screen interface elements before the user performs an actual touch operation when the confusion or hesitation state is identified. This invention effectively reduces the learning cost and cognitive load for users in complex in-vehicle interfaces, and improves the intuitiveness and efficiency of interaction.
