（Ⅱ） Data Collection

1. After the human body model is created, relevant data collection can begin.
2. Enter the file name for the data to be collected in the "File Box" at the bottom of the software interface. Avoid using Chinese characters or special symbols in the file name. After confirmation, press Enter.

3. After entering the file name for data collection, click the red recording button below to start collecting data. Click the recording button again to stop the recording, and a pop-up window will prompt that the data has been collected.

4. After recording a set of data, the number on the right side of the "File" input box will change to 2, indicating that the next recording will be the second set of data for this file name. Without changing the file name, this number will increment sequentially after each set of data is recorded.

5. If there is an issue with recording the second set of data, or for other reasons, you want to re-record this set of data, change the number to 2, click the "Overwrite" button on the left, and then click the recording button to re-record. The same operation can be applied to other sets of data.
