Šio baigiamojo bakalauro darbo tyrimo tikslas ištirti akies ir rankos koordinuotų judesių savybes sekant taikinį skirtingo pločio labirintais, taikiniui judant skirtingais greičiais. Akių judesiams registruoti buvo panaudota EyeGaze System, o rankos judesiams registruoti - WACOM Intuos® 2 XD-1212-U grafinė planšetė. Tiriamiesiems reikėjo pravesti taikinį trim skirtingo pločio labirintais. Tyrimo metu buvo registruojami akių ir rankos judesiai, pagal kurios buvo analizuojami žvilgsnio šuolio amplitudės, atstumas tarp rankos ir žvilgsnio prieš įvykstant žvilgsnio šuoliui, akies ir rankos greičių santykis bei gautieji rezultatai įvertinti remiantis Fitso dėsniu, kuris įvertino, kaip tiksliai ir greitai tiriamieji atliko labirintus. Gautieji rezultatai parodė, kad didėjant rankos greičiui ir esant platesniam labirintui žvilgsnio šuolių amplitudžių ir atstumo tarp rankos ir žvilgsnio prieš įvykstant žvilgsnio šuoliui vidurkiai bei jų standartiniai nuokrypiai didėja. Akies ir greičio santykis parodė, kad esant mažesniems greičiams akis lenkia ranką, o didėjant ranka pralenkia akį. Tyrimo rezultatai gali būti panaudoti kuriant robotų programinę įranga, neurofiziologinių procesų analizei bei įvertinti žmogaus koordinaciją reabilitacijos metu. / The theme of Bachelor project of Electronics engineering is important for research in biomedical engineering. In my purpose is to investigate eye-hand coordination during target guiding by hand along labyrinth.
Investigatives have to guide a target in different wide of labyrinth. First they have to guide a target in the narrowest labyrinth, which wide is 10 px, later in the widest labyrinth, which wide is 39 px and last in moderate labyrinth, which wide is 15 px. In this labyrinth investigatives have to guide targets of two different sizes. They have to guide at different speed and precision. Eye coordinates were recorded by EyeGaze System, which produced LC Technologies, Ltd. Hand coordinates were recorded by WACOM Intuos® 2 XD-1212-U graphic tablet.
During the research recorded eye and hand coordinates, which were analysed. Due to this information, were calculated gaze jump amplitudes, distance between the gaze and hand before gaze will do a jump, gaze and hand speed ratio and results were evaluated by Fitts‘s law. Results revealed that average and standart deviation of these parameters are major if speed of target becomes faster and labyrinth is wider. Gaze and hand speed ratio revealed, that at slow speed gaze overtake a hand and vice versa. In accordance with results, which were evaluated by Ftts‘s law, revealed that the longest duration and least precision are in the narrowest labyrinth. The shortest duration and the best precision are in the widest labyrinth... [to full text]
