Development of a contactless operation system for radiographic consoles using an eye tracker for severe acute respiratory syndrome coronavirus 2 infection control: a feasibility study

<p class="Abstract">Sterilization of medical equipment in isolation wards is essential to prevent the transmission severe acute respiratory syndrome coronavirus 2 (SARS–CoV-2) infection. Particularly, radiographic console portable X-ray machines requires frequent disinfection because it regularly moved; this considerable infection control effort as number patients with disease 2019 (COVID-19) increases. To evaluate application a system facilitating noncontact operation consoles for COVID-19 reduce need disinfection. We developed that used common eye tracker. compared calibration errors between and without face shield conditions. Moreover, use among 41 participants was investigated. The error tracker conditions did not significantly differ. All (<em>n</em> = 41) observers completed operation. Pearson’s correlation coefficient analysis showed strong (<em>r</em> 0.92, <em>P</em> < 0.001) average time misoperations. Our an can be applied even if operator uses shield. Thus, its important preventing infection.</p>
