Operating Steps

Download the SEN0670_Upper Computer Software, save it to a local folder, and unzip it. Locate the SEN0670-AI Posture and Gesture Sensor.exe file as shown in the image below.
Double-click the .exe file to open the host computer, and you will see the Upper Computer Software interface as shown in the image below.
Click the port drop-down menu, select the matched serial port (e.g. COM27 (USB-SERIAL CH340K)), then click Open Serial Port → Connect Device to access the real-time camera feed and recognition data.

The Upper Computer Software Functions are as follows:

Function Name Concise Description

Function Switch Toggles between Gesture Recognition and Posture Recognition modes.

Data Display Area Shows gesture ("hand_keypoints": []) or posture ("pose_keypoints": []) data, with one-click copy support.

Learn Button Learns and custom-names detected gestures/postures; max 8 custom gestures + 8 postures.

Clear Button Erases all learned custom gestures/postures.

Baud Rate Display Reads the current sensor serial baud rate; baud rate modification is not supported.

Function Name	Concise Description
Function Switch	Toggles between Gesture Recognition and Posture Recognition modes.
Data Display Area	Shows gesture ("hand_keypoints": []) or posture ("pose_keypoints": []) data, with one-click copy support.
Learn Button	Learns and custom-names detected gestures/postures; max 8 custom gestures + 8 postures.
Clear Button	Erases all learned custom gestures/postures.
Baud Rate Display	Reads the current sensor serial baud rate; baud rate modification is not supported.

The Upper Computer Software defaults to the Gesture Recognition function. It will display the ID, confidence score, and 21 keypoint data of any detected gesture in real time.
Gesture Learning Steps: When the camera screen recognizes a custom gesture, click the Learn Button and keep the gesture stationary for 3~4 seconds until the learning is completed (the color of the gesture will change at this time).
There is no need to power off the sensor; simply click the Function Switch to directly switch to the Posture Recognition function. The posture recognition experience is shown in the image below.
The posture learning steps are the same as the gesture learning steps and will not be repeated here. Note: The optimal distance for gesture recognition is 50~60cm; the minimum distance for posture recognition is 2m.
