Multimodal trajectory information processing and analysis system based on man-machine interaction terminal

A multimodal trajectory information processing and analysis system based on man-machine interaction terminal, comprising:

• a collection sensor, an information processing device, and data transmission interface;
• wherein the collection sensor is configured to collect, finger operation trajectory information comprising real-time operation interaction information, and send the collected finger operation trajectory information to the information processing device through the data transmission interface;
• the information processing device is configured to receive a display interface of a device under test in real time, and is configured to fuse and display the collected finger operation trajectory information corresponding to the display interface of the device under test, and obtain an evaluation system of man-machine interaction experience by analyzing finger operation trajectories;
• and
• a bracket and a lifting device;
• wherein the bracket is configured to place the device under test and support an upper limb of a tester;
• the lifting device is connected to the bracket and is configured to adjust a location of the bracket;
• and
• the collection sensor is fixed arranged on the lifting device at an end away from the bracket.
