User-Defined Gestures with Physical Props in Virtual Reality
When building virtual reality (VR) environments, designers use physical props to improve immersion and realism. However, people may want to perform actions that would not be supported by physical objects, for example, duplicating an object in a Computer-Aided Design (CAD) program or darkening the sky in an open-world game. In this thesis, I present an elicitation study where I asked 21 participants to choose from 95 props to perform manipulative gestures for 20 referents (actions), typically found in CAD software or open-world games. I describe the resulting gestures as context-free grammars, capturing the actions taken by our participants, their prop choices, and how the props were used in each gesture. I present agreement scores between gesture choices and prop choices; to accomplish the latter, I developed a generalized agreement score that compares sets of selections rather than a single selection, enabling new types of elicitation studies. I found that props were selected according to their resemblance to virtual objects and the actions they afforded; that gesture and prop agreement depended on the referent, with some referents leading to similar gesture choices, while others led to similar prop choices; and that a small set of carefully chosen props can support a wide variety of gestures
Metafore mobilnih komunikacija ; Метафоры мобильной связи.
Mobilne komunikacije su polje informacione i komunikacione tehnologije koje karakteriše brzi
razvoj i u kome se istraživanjem u analitičkim okvirima kognitivne lingvistike, zasnovanom na
uzorku od 1005 odrednica, otkriva izrazito prisustvo metafore, metonimije, analogije i
pojmovnog objedinjavanja. Analiza uzorka reči i izraza iz oblasti mobilnih medija, mobilnih
operativnih sistema, dizajna korisničkih interfejsa, terminologije mobilnih mreža, kao i slenga
i tekstizama koje upotrebljavaju korisnici mobilnih naprava ukazuje da pomenuti kognitivni
mehanizmi imaju ključnu ulogu u olakšavanju interakcije između ljudi i širokog spektra
mobilnih uređaja sa računarskim sposobnostima, od prenosivih računara i ličnih digitalnih
asistenata (PDA), do mobilnih telefona, tableta i sprava koje se nose na telu. Ti mehanizmi
predstavljaju temelj razumevanja i nalaze se u osnovi principa funkcionisanja grafičkih
korisničkih interfejsa i direktne manipulacije u računarskim okruženjima. Takođe je analiziran
i poseban uzorak od 660 emotikona i emođija koji pokazuju potencijal za proširenje značenja,
imajući u vidu značaj piktograma za tekstualnu komunikaciju u vidu SMS poruka i razmenu
tekstualnih sadržaja na društvenim mrežama kojima se redovno pristupa putem mobilnih
uređaja...Mobile communications are a fast-developing field of information and communication
technology whose exploration within the analytical framework of cognitive linguistics, based
on a sample of 1005 entries, reveals the pervasive presence of metaphor, metonymy analogy
and conceptual integration. The analysis of the sample consisting of words and phrases
related to mobile media, mobile operating systems and interface design, the terminology of
mobile networking, as well as the slang and textisms employed by mobile gadget users shows
that the above cognitive mechanisms play a key role in facilitating interaction between people
and a wide range of mobile computing devices from laptops and PDAs to mobile phones,
tablets and wearables. They are the cornerstones of comprehension that are behind the
principles of functioning of graphical user interfaces and direct manipulation in computing
environments. A separate sample, featuring a selection of 660 emoticons and emoji, exhibiting
the potential for semantic expansion was also analyzed, in view of the significance of
pictograms for text-based communication in the form of text messages or exchanges on social
media sites regularly accessed via mobile devices..
