Dual Hands Data Collection Guide
Data Collection Guide for Dual Hands V1.0
Notes
(1) USB Connection Security
During pairing, ensure the USB connection is secure. Use straps to minimize tension on the USB ports during collection. If the pairing indicator on the recording interface flickers or disappears, it indicates an unstable USB connection (refer to the fixation solution provided by Genrobot)
(2) Recording Operations
After successful pairing, use the record button on the left-hand device to initiate recording operations.
(3) Data Collection Initialization
During the actual data collection, please ensure that both devices are facing the same spot when starting the collection. Wait for 1 second in a stationary state before beginning the collection.
1. How to Pair on the Interface
(1) Connect both devices using a dual-ended USB cable.
(2) Turn on the pairing switch on both devices.
(3) Designate the left-hand device as the host. Long-press the pairing switch on the left-hand device and select "Left" on the pairing interface.
(4) Then, long-press the pairing switch on the right-hand device and select "Right" on its pairing interface.
(5) Upon successful connection, the pairing indicators for Left and Right should be displayed at the top of the recording interface on both devices, respectively.
(6) Finally, use the record button on the left-hand device to control the start and stop of data recording for both hands. The right-hand device is not controllable for this function.
2. Recording Data to the SD Card
(1) After recording data to the SD card, the bag names will distinguish between the host and client devices
