Razvoj aplikacije za validacijo sledilnika pogleda v očalih za navidezno resničnost

MAURIČ, ANA (author), Sodnik, Jaka (mentor)

Tehnologija in oprema navidezne resničnosti se s časom vedno bolj razvija in nadgrajuje. Dobra uporabniška izkušnja v navidezni resničnosti med drugimi temelji na kvalitetnem prikazu okolice - očala morajo zato zagotavljati pravilno oz. natančno sledenje pogleda uporabnika. Eden izmed najbolj uspešnih podjetij na področju navidezne resničnosti je Tajvanska znamka HTC Vive. Ponuja in razvija rešitve v različnih industrijah - šolstvu, zdravstvu, zabavi, marketingu itd. Leta 2015 so izdelali svoja prva očala za navidezno resničnost, imenovana HTC Vive, leta 2018 pa nadgrajena Vive Pro Eye očala, ki so predmet obravnave te naloge. Namen tega dela je določiti točnost sledilnika pogleda Vive Pro Eye očal. Glavno vprašanje je, v kolikšni meri se zabeleženo sledenje pogleda ujema z dejanskim premikanjem opazovanega objekta. Ta diplomska naloga najprej predstavi teoretično ozadje sledenja pogleda v navidezni resničnosti, tehnične specifikacije in študije z Vive Pro Eye očali. Nadaljuje se z opisom naše aplikacije v platformi Unity - potek izdelave, prilagajanje delovanja aplikacije z očali in končna povezava aplikacije z opremo navidezne resničnosti. Sledi opis izvedbe eksperimenta na prostovoljcih (prostovoljci so igrali vlogo uporabnikov, katerih pogled se zabeleži) in analiza rezulatov eksperimenta. Naloga s primerjavo grafičnih predstavitev gibanja tarče, pogleda in fiksacij nudi vpogled v delovanje sledilnika na različnih uporabnikih, glede na unikatno gibanje tarče na zaslonu v njihovi navidezni okolici.

• Title: Development of an application for the validation of an eye tracker in virtual reality glasses

Abstract

Virtual reality technology and equipment continues to evolve and improve over time. A good user experience in virtual reality is among other things based on the quality of the virtual environment - the glasses must therefore ensure that the user's gaze is correctly or accurately tracked. One of the most successful companies in the field od virtual reality is the Taiwanese brand HTC Vive. It offers and develops solutions in various industries - education, healthcare, entertainment, marketing, etc. In 2015, they produced their first virtual reality glasses, called HTC Vive, and in 2018 they produced new and upgraded Vive Pro Eye glasses, which are the subject of this thesis. The purpose of this work is to determine the accuracy of the Vive Pro glasses' gaze tracker. The main question is, to what extent does the recorded gaze tracking match the actual movement of the observed object. This thesis first presents the theoretical background of gaze tracking in virtual reality, technical specifications and studies with the Vive Pro Eye glasses. It goes on to describe our app in the Unity platform - the build process, how to make the app work with the headset, and the final integration of the app with the virtual reality equipment. This is followed by a description of the experiment on volunteers (volunteers played the role of subjects whose gaze is recorded) and an analysis of the results of the experiment. By comparing graphical representations of target motion, gaze and fixations, this task provides insight into the performance of the tracker on different subjects with respect to the unique motion of the on-screen target in their environment.
