Ltd Support Platform Notes SDK for Windows Unity3D SDK Need to be used with USB2BLE gForce Dongle Win 7/ win8 / win10 With original Bluetooth BLE 4.0 and above Android Unity3D SDK SDK for Arduino/STM32 ArduinoSTM32 Need to be used with UART2BLE gForce-Joint (Contact the manufacturer for purchase additionally) Android MCU 6.2. gForce OTrain gesture training platform 6.2.1. Otrain gesture training platform is based on hybrid development concept and adopts C / S architecture. The internal tools of the platform include web server, data collection service, machine learning engine and interface display service. 6.2.2. The personal gesture training, modeling and uploading of gforce EMG Armband can be completed through the guidance of OTrain platform to achieve personalized gesture customization. gForce can work offline after gesture training. 3 6.3. gForce and Arduino development board (additional purchase required) All Rights Reserved by OYMotion Technologies, Co. Ltd gForce Joint acts as a Bluetooth Center and can automatically establish a connection with gForce Pro Armband through Bluetooth BLE for data transmission. gForce Pro sends the recognized gesture index and quaternion values to gForce Joint. gForce Joint forwards the received gesture index and quaternion values to the next level through its COM port (TX). Arduino receives gesture index and quaternion values from gForce Joint through its COM port (Rx) . 6.4. Key points of using gForce Pro Armband 6.4.1. When using gForce Armband, it should be close to the skin and worn in the middle of forearm. 6.4.2. In the power OFF state, press the switch button gently, the armband starts, the green indicator light is on, and it flashes slowly; in the power ON state, press the switch button lightly, and set the gyroscope as the current direction. 6.4.3. In the power ON state, long press the switch button for five seconds to release, the armband is closed, and the green indicator light is off. 6.4.4. When charging the armband, the red charging indicator light is on; when charging is completed, the indicator light is off. 6.4.5. When connecting the armband to OTrain, try to be as close to Dongle as possible. When the green indicator light flashes, it indicates that the connection is successful. 6.4.6. In the process of training gestures in OTrain platform, when switching from one gesture to another, the green light is always on, indicating that the new gesture training mode has been entered, and the training can be started. 6.4.7. When making gestures, gestures need to be performed when the user's arm muscles are relaxed. 7. gForce technical parameters Main indicators Specific parameters Communication mode Low power Bluetooth BLE4.2 standard Communication distance 10m 4 All Rights Reserved by OYMotion Technologies, Co.
