Augmented reality based system for virtual room lighting application

Obogatena resničnost je tehnologija, ki združuje virtualni in realni svet in nam omogoča doživljanje realnega sveta z dodanimi virtualnimi elementi. Tehnologija je še vedno v razvoju, vendar počasi prehaja v zrelo obdobje in je uporabna na številnih področjih. Svet filma in gledališča ponuja gledalcem čudovite vizualne podobe in doživetja. Za izdelavo kvalitetnih izdelkov je potrebno veliko drage opreme, še posebno pri večjih snemalnih projektih. Zato se vprašamo, ali obstaja možnost združitve AR s filmskim svetom in s tem omogočiti direktorjem fotografije, da si vnaprej opremijo virtualni set ter prihranijo energijo in čas s prenašanjem in prestavljanjem opreme. Ravno temu izzivu in rešitvi se posvečamo v tem delu. V uvodnem delu diplomskega dela je opisana kratka zgodovina obogatene resničnosti in teoretično ozadje delovanja naprav, ki jo omogočajo. Sledi opis sistema za virtualno osvetljevanje prostora na podlagi obogatene resničnosti ter naprave MS Hololens. Sistem omogoča 3D-analizo prostora okoli nas, omogoča virtualno postavljanje luči v prostor ter njihov nadzor. Rešitev smo evaluirali s standardnimi metodami za merjenje uporabniške izkušnje. V pilotsko uporabniško študijo je bilo vključenih pet uporabnikov, ki so jo ocenili preko standardnega vprašalnika za uporabniško izkušnjo (User Experience Questionnaire), hkrati pa smo preverili še možnost simulacijske slabosti (Simulator Sickness Questionnaire) ter zbrali njihove komentarje. Aplikacija je bila dobro sprejeta, vendar se je trenutno izkazala kot manj primerno za profesionalno uporabo.Augmented reality is a technology that merges virtual and real world, which enables us experiencing real world with added virtual elements. Technology around AR is still developing, but it is already useful in many different fields. Film and theatre are entertaining their visitors with incredible visual masterpieces and experiences. In order to develop such works, a lot of expensive equipment, especially on bigger sets, is needed. Therefore the question emerges – Is there a chance of merging the world of AR with the world of film? It would be a big advantage for the directors of photography, giving them a tool to develop their own virtual movie set, prevent wasting their energy and save time with moving the equipment. This thesis covers a short history of augmented reality and theoretical background of how the equipment works. Than follows a description of augmented reality based system for virtual lighting and Microsoft Hololens device. The system enables us 3D environmental mapping, adding of lights into the scene and controlling their characteristics. The solution was tested with standard methods for measuring user experience. 5 users, who participated in the pilot user experience study, evaluated the application through User Experience Questionnaire. At the same time the possibility of simulator sickness was checked with Simulator Sickness Questionnaire and users\u27 experience with our solution were collected. The solution was positively rated, but has proven itself to be inappropriate for professional use
