20.500.12556/RUL-160091 Effectiveness of a time to fixate for fitness to drive evaluation in neurological patients We present a method to automatically calculate time to fixate (TTF) from the eye-tracker data in subjects with neurological impairment using a driving simulator. TTF presents the time interval for a person to notice the stimulus from its first occurrence. Precisely, we measured the time since the children started to cross the street until the drivers directed their look to the children. From 108 neurological patients recruited for the study, the analysis of TTF was performed in 56 patients to assess fit-, unfit-, and conditionally-fit-to-drive patients. The results showed that the proposed method based on the YOLO (you only look once) object detector is efficient for computing TTFs from the eye-tracker data. We obtained discriminative results for fit-to-drive patients by application of Tukey’s honest significant difference post hoc test (p < 0.01), while no difference was observed between conditionally-fit and unfit-to-drive groups (p = 0.542). Moreover, we show that time-to-collision (TTC), initial gaze distance (IGD) from pedestrians, and speed at the hazard onset did not influence the result, while the only significant interaction is among fitness, IGD, and TTC on TTF. Obtained TTFs are also compared with the perception response times (PRT) calculated independently from eye-tracker data and YOLO. Although we reached statistically significant results that speak in favor of possible method application for assessment of fitness to drive, we provide detailed directions for future driving simulation-based evaluation and propose processing workflow to secure reliable TTF calculation and its possible application in for example psychology and neuroscience. eye tracker driving simulation neurology patients fitness to drive object detection time to fixate sledilnik pogleda simulacija vožnje nevrološki pacienti sposobnost za vožnjo detekcija objektov čas fiksacije true false true Angleški jezik Slovenski jezik Članek v reviji 2024-08-19 14:08:59 2024-08-19 14:09:02 2024-08-20 03:46:12 0000-00-00 00:00:00 2024 0 0 Str. 4277-4292 iss. 5 Vol. 56 Aug. 2024 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 004.94:629.4.072 1554-3528 10.3758/s13428-023-02177-3 159757315 s13428-023-02177-3_(2).pdf s13428-023-02177-3_(2).pdf 1 E7AFBBA664815C9A5ADD16FFD3779803 2992ce469d5db1901a38766f3692b821a5afafb0cf7fe3fef8fd1d2a6866a44e f6aa253a-5e23-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188550 https://link.springer.com/article/10.3758/s13428-023-02177-3 1 a172810b-5e23-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188549 Fakulteta za elektrotehniko 0 0 0
