Two novel personal calibration procedures that do not require active user participation are presented. These procedures, in conjunction with a state-of-the-art remote eye-gaze tracking (REGT) technology, allow estimation of the angle between the optical and visual axes (angle kappa) automatically without explicit/active user involvement. The first algorithm for the binocular estimation of angle kappa (BEAK) is based on the assumption that at each time instant both eyes look at the same point on a surface with a known geometry (e.g., a computer monitor). The sensitivity of the BEAK procedure to the geometry of the observation surface and to the noise in the estimates of the optical axis is studied both analytically and in computer simulations. Experimental results with 4 adult subjects suggest that with the current REGT technology angle kappa can be estimated with an RMS error of 0.5°. The second personal calibration algorithm (‘calibrate and validate’, CaVa) adopts a probabilistic approach to the estimation of angle kappa in infants. Even though the presentation of visual stimuli at known positions is part of the procedure, the CaVa algorithm does not require/assume continuous fixation on the presented targets. If an infant attends to roughly half of the presented targets, angle kappa can be estimated accurately and with high confidence. In experiments with five babies, the average difference between repeated measurements of angle kappa was 0.04 ± 0.31°. The second part of the thesis describes two methods for automated measurement of eye misalignment in adults and infants. These methods are based on the user-calibration-free (UCF) technology presented in the first part of the thesis. The first method is based on the clinical Hirschberg test. It is shown that the UCF-REGT technology can improve significantly the accuracy of the Hirschberg test by enabling the estimation of subject-specific parameters (the Hirschberg ratio and angle kappa) in infants. The maximum error in the estimation of the horizontal and vertical components of eye misalignment in five orthotropic infants was shown to be less than 1°, which is significantly better than the accuracy of a standard clinical Hirschberg test. Finally, a novel Eye-Tracker Based Test (ETBT) for the estimation of the maximum (manifest + latent) angle of deviation is presented. ETBT is based on the UCF-REGT system. ETBT allows free head movements and does not require continuous fixation on specific targets. Experiments with 22 adult subjects demonstrated a good agreement of 0.7 ± 1.7° between ETBT and the gold-standard clinical procedure—the altenate prism and cover test. A pilot study with 5 orthotropic infants and one infant with strabismus demonstrated that the ETBT can be used in infants.

This thesis describes design gallery of aviation technology and traditions at the airport in Brno Part of my thesis is focused on urban solution of area layout its interconnections with near districts “Komín“ and “Medlánky“. There is new pedestrian, cycling paths, operational and logistic roads inside the complex layout. This design supposed to keep the two existing historic hangars and demolishing remaining buildings with subsequent completion of necessary objects. Priority and the main idea is to keep compositional and visual axis to ensure visual contact with all airport operational parts to ease of orientation. According to this principle is mass and platform solved with object “gallery”. This object in addition to the exhibition space is also used for administration and operation department of the gallery. In separate part there is ensured catering in form of restaurant with associated technical, operational and sanitary facilities. The gallery is designed to visually and physically separate section used by pilots and airport vehicles from visitors to avoid dangerous situation. Other buildings I have designed in my project are “the clubhouse”, airport administration, emergency accommodation, social activity space mainly designed for aircraft-model pilots and the air traffic control tower. These objects creates border between premises restricted for aero club and visitors.
