How does the Otakus Cam perform its scan?

Question

The function of what intrigues me is the Otaku's Cam. What actions are accomplished in the process of its scan, does it work or is it inconvenient, may be even painful?

Answer 1

Over the course of this research, the [Otakus Cam] shall be elastically controlled by the patient's hand scanning points. This technique seems subtle, and it registers photometric signals from biological tissues. After obtaining the information from the photometry for relative time, conclusions shall be derived after the information is processed in the cloud.
