In this article, the authors present an image processing method to reduce three-dimensional (3D) crosstalk for eye-tracking-based 3D display. Specifically, they considered 3D pixel crosstalk and offset crosstalk and applied different approaches based on its characteristics. For 3D pixel crosstalk which depends on the viewer’s relative location, they proposed output pixel value weighting scheme based on viewer’s eye position, and for offset crosstalk they subtracted luminance of crosstalk components according to the measured display crosstalk level in advance. By simulations and experiments using the 3D display prototypes, the authors evaluated the effectiveness of proposed method.

This study develops an eye tracking method for autostereoscopic three-dimensional (3D) display systems for use in various environments. The eye tracking-based autostereoscopic 3D display provides low crosstalk and high-resolution 3D image experience seamlessly without 3D eyeglasses by overcoming the viewing position restriction. However, accurate and fast eye position detection and tracking are still challenging, owing to the various light conditions, camera control, thick eyeglasses, eyeglass sunlight reflection, and limited system resources. This study presents a robust, automated algorithm and relevant systems for accurate and fast detection and tracking of eye pupil centers in 3D with a single visual camera and near-infrared (NIR) light emitting diodes (LEDs). Our proposed eye tracker consists of eye–nose detection, eye–nose shape keypoint alignment, a tracker checker, and tracking with NIR LED on/off control. Eye–nose detection generates facial subregion boxes, including the eyes and nose, which utilize an Error-Based Learning (EBL) method for the selection of the best learnt database (DB). After detection, the eye–nose shape alignment is processed by the Supervised Descent Method (SDM) with Scale-invariant Feature Transform (SIFT). The aligner is content-aware in the sense that corresponding designated aligners are applied based on image content classification, such as the various light conditions and wearing eyeglasses. The conducted experiments on real image DBs yield promising eye detection and tracking outcomes, even in the presence of challenging conditions.

Tracking Technology

Prostredníctvom technológie eye-trackingu sme pri využití vnútrosubjektového dizajnu u 50 pokusných osôb zaznamenávali pohyby očí pri vypĺňaní päťfaktorového osobnostného inventára NEO-FFI v podmienke úprimného vs "fake good" vypĺňania. Výsledky indikujú, že ľudia sú schopní skresľovať odpovede v osobnostnom dotazníku. Participanti inštruovaní skresľovať odpovede za účelom vytvorenia portrétu najvhodnejšieho uchádzača o pracovné miesto po prečítaní otázky častejšie zamerali vizuálnu pozornosť priamo na extrémne typy odpovedí („platí to pre mňa úplne“, „neplatí to pre mňa vôbec“), preukazovali nižší celkový reakčný čas a celkový počet fixácií potrebných na odpovedanie na položky. V kontraste s uvedeným bolo úprimné odpovedanie charakterizované vizuálnou pozornosťou, ktorá po prečítaní otázky častejšie smerovala na stredné možnosti odpovedí („platí to pre mňa prevažne“, ani platí ani neplatí“, „platí to pre mňa len málo“) než na extrémne, celkový čas potrebný na odpovedanie bol dlhší a počet fixácií bol vyšší ako pri skresľovaní. Tieto výsledky sú v zhode s teóriami, ktoré predpokladajú čisto sémantickú interpretáciu položiek osobnostných dotazníkov pri falošnom správaní uchádzačov o zamestnanie. Metóda sledovania pohybov očí pomocou eye‐trackingu sa tak v tomto kontexte javí ako pomerne nádejná.We conducted a laboratory experiment in an experimental design within-participants with a research sample of 50 persons. Eye-tracking technology is used to collect data for detection of eye behavior while responding to a NEO – FFI in „fake good“ and honest condition. Results indicate that people are capable of faking personality test. Participants when instructed to fake good on personality items, for the purpose of making impression as the most suitable job applicant, more often engaged eye behavior characterized by direct fixation to extreme response option after having read the item, also lower response times and less eye fixiations in general. In contrast the pattern of results for answering honestly is characterized by direct fixation of visual attention on the middle response categories, slower response times and more fixations in general. Confirming previous research, our eye-tracking data show more direct evidence for a semantic item interpretation characterization of the response process when faking. We consider eye-tracking technology as valuable and beneficial method in detecting intentional response distortion of personality tests in personal selection process.
