“…In other words, the experiments were conducted in an environment similar to a hospital room. In addition, there are cases in which eye tracker was used in hospital rooms in previous studies, although these studies were not directly operating computers [29], [30]. Therefore, we believe that the system in this study can be used without problems in the isolation ward where it is planned to be used.…”

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

“…So called video occulography eye trackers use a video camera which can be positioned in front of a subject or be head mounted (e.g., on eyeglasses frame), to track the position of the eyes [ 11 , 12 ]. Eye trackers are considered as robust and are already an established technology as communication systems for disabled persons; commercial systems such as the Tobii eye tracking devices (Tobii AB, Danderyd, Stockholm, Sweden) have become a valuable tool in augmentative communication [ 13 , 14 , 15 ].…”

A Novel Hybrid Mental Spelling Application Based on Eye Tracking and SSVEP-Based BCI

et al. 2017

Steady state visual evoked potentials (SSVEPs)-based Brain-Computer interfaces (BCIs), as well as eyetracking devices, provide a pathway for re-establishing communication for people with severe disabilities. We fused these control techniques into a novel eyetracking/SSVEP hybrid system, which utilizes eye tracking for initial rough selection and the SSVEP technology for fine target activation. Based on our previous studies, only four stimuli were used for the SSVEP aspect, granting sufficient control for most BCI users. As Eye tracking data is not used for activation of letters, false positives due to inappropriate dwell times are avoided. This novel approach combines the high speed of eye tracking systems and the high classification accuracies of low target SSVEP-based BCIs, leading to an optimal combination of both methods. We evaluated accuracy and speed of the proposed hybrid system with a 30-target spelling application implementing all three control approaches (pure eye tracking, SSVEP and the hybrid system) with 32 participants. Although the highest information transfer rates (ITRs) were achieved with pure eye tracking, a considerable amount of subjects was not able to gain sufficient control over the stand-alone eye-tracking device or the pure SSVEP system (78.13% and 75% of the participants reached reliable control, respectively). In this respect, the proposed hybrid was most universal (over 90% of users achieved reliable control), and outperformed the pure SSVEP system in terms of speed and user friendliness. The presented hybrid system might offer communication to a wider range of users in comparison to the standard techniques.
