Hello @141391,
The datasheet of the VL53L8CX sensor indicates a field of view of 45° horizontally and vertically, this means for a distance of 20cm, the sensor perceives in a 16cm square. Depending on the size of your hands, it may be better to place the development kit 20 to 30cm away from your palm to let it perceive the background behind. Also it is not very intuitive but the BreakTime sign is detected when you do a timeout sign (basically a T with your hands).
The provided neural network is trained with a small dataset and therefore it is not very accurate. If you want to create a better dataset, optimized for the position and the distance between your hand and the sensor, you can create one easily by following this tutorial.
