When surgical operations are being performed under a microscope, the surgeon needs to work with high concentration and precision. However, it is difficult to control the functions on existing microscopes when both hands needed for the operation. The Squid Surgical BCI (Brain Computer Interface) comes in to control all functions of a surgical microscope, resulting in a much more ergonomic work process. This area of application allows Squid Surgical BCI to become the first real BCI tool in the near future. When connecting the whole system with a microscope, the individual neural code is collected from the brain, sent wirelessly to the tablet, which then converts the neural code into a binary code. At this point, the interface sends the commands to the microscope to execute the desired functions. Before connecting the BCI system to a microscope, the user needs to practise specific training sequences so that the tablet can learn the individual patterns of thought and command execution.
