Figure 7 shows the prototype of the ICT laparoscopy system, engineered to mitigate the challenges previously outlined and facilitate solo surgery. This innovative prototype incorporates a hairband controller module that captures user motion in real time and transmits this information to the main unit when donned on the user's head. Additionally, it features a foot pedal switch for initiating the motion tracking of the head and a central unit responsible for transmitting and receiving data to regulate camera movement. The operation of the ICT laparoscopy system shown in Figure 7 is delineated in the following steps.  
Step 1: The activation of the camera module is achieved by centering the camera and engaging the foot switch, setting the stage for the controller to commence motion tracking.  
Step 2: Equipped with motion-tracking technology, the hairband controller responds to the user's head movements, enabling dynamic system control.  
Figure 7: The operation procedure of the ICT laparoscopy system involves the following steps. First, (a) initiate the system by activating the foot switch (Step 1). (**b**) The user wears it on their head, and their head motion is tracked in real-time (Step 2). Next, (**c**) the camera is adjusted according to this motion (Step 3).  
Step 3: By interpreting the user's motions, the hairband controller transmits a command signal to the camera, aligning the viewing perspective with the user's intent.  
This operational flow highlights the ICT laparoscopy system's intuitive and efficient functionality. Safety tests, including leakage current, grounding resistance, and power input, were performed in alignment with the General Requirements for Basic Safety of Medical Electrical Equipment (IEC 60601-1 series) by KTL. These tests are crucial components of the General Requirements for the Basic Safety of Medical Electrical Equipment, ensuring the medical device's essential performance and basic safety in clinical settings. In the leakage current test, the leakage current of the device must be below the Ministry of Food and Drug Safety (MFDS) standards. In the grounding resistance test, for a device with a power socket, if the impedance between the protective grounding point of the power socket and grounded contactable metal parts does not exceed 0.1 \(\Omega\), the test passes, and in this case, the test passed with 0.052 \(\Omega\). The power input test is divided into devices that consume power by electric motors and other devices. This prototype belongs to devices other than those that consume power from electric motors. Hence, it is classified as another device. In the power input test of this prototype, the input current or power in the normal state under the rated voltage, normal operating temperature, and operating conditions set by the manufacturer must be less than 10% of the rated input exceeds 100 W or 100 VA, and this was satisfied (refer to Table 1). The prototype passed several safety tests for leakage current, grounding resistance, and power input. This achievement paves the way for further testing to ensure compliance with all requirements outlined in the General Requirements for Basic Safety of Medical Equipment in the future.  
Performance evaluations conducted by KTL-assessed dimensions and camera rotation angle. The main body dimensions were 192.86 mm in width, 192.58 mm in height, and 94.63 mm in depth. The camera showed degrees of freedom for movement in the up, down, left, and right directions, with rotation angles defined as 88\({}^{\circ}\) upward, 89.55\({}^{\circ}\) downward, 92.5\({}^{\circ}\) to the left, and 88.05\({}^{\circ}\) to the right, highlighting the system's versatility in camera motion control based on controller inputs.
