Video projection mapping e arti performative. Una nuova macchina scenotecnica della visione per generare nuovi spazi aumentati
L’oggetto principale della dissertazione è il video projection mapping, un’applicazione di realtà aumentata che utilizza le tecniche di videoproiezione digitale non su tradizionali schermi di proiezione ma sulla realtà stessa, sugli oggetti fisici, ai quali si adatta e si lega in maniera inestricabile, ibridando il livello fisico-reale e il livello digitale. Al contrario di come spesso è stato considerato, il video projection mapping non è solo un gadget tecnologico dei nostri tempi; quando si ibrida con altri media, come le arti performative, diviene linguaggio metaforico, oltrepassando il suo livello tecnologico per produrre significati, per mediare idee. Considerando il suo uso nello spe…
Affordances and signifiers in virtual learning environment design
2016
Virtuaalioppimisympäristöt edustavat suhteellisen uutta opetusmuotoa. Näiden ympäristöjen suunnittelussa on opetukselle asetettujen vaatimusten huomioimisen lisäksi oleellista ymmärtää yksilön tavat kokea ja ymmärtää käytössä oleva teknologia. Koettu käytettävyys on käsite, joka kuvaa tuote- tai palvelusuunnittelua siltä osin, kuinka ihmiset ymmärtävät käytettävyyttä ja käytön helppoutta. Nämä ymmärrykset on johdettu kohteiden ominaisuuksista ja toiminnoista eli affordansseista, jotka ovat erilaisten vihjeiden eli merkitsijöiden tarjoamia viittauksia siitä, miten kohdetta voidaan käyttää. Tämä tutkielma on toteutettu kirjallisuuskatsauksena. Sen tarkoituksena on määritellä käsitteenä virtua…
Promoting empathy through virtual reality experience: the case of sexual harassment
2020
Introducción: En los últimos decenios, la realidad virtual (RV) se ha adoptado de manera exponencial en la psicología clínica para tratar varios trastornos psicológicos y promover el bienestar. La RV es una forma avanzada de interfaz humano-computadora que permite al usuario interactuar y estar presente en un entorno tridimensional de manera naturalista. El uso de la RV se ha ampliado para simular no sólo el mundo exterior, sino también la experiencia corporal, dando la ilusión de encarnar un cuerpo "virtual". Cuando esta ilusión se induce con éxito, el participante puede percibirse a sí mismo como otra persona y sentir las emociones del cuerpo encarnado. Este modelo se ha adoptado para est…

Behavioral Activation through Virtual Reality for Depression: A Single Case Experimental Design with Multiple Baselines
2022
Behavioral activation (BA) is a structured psychotherapeutic approach for the treatment of major depressive disorder (MDD), which aims at increasing the engagement in activities that might bring enjoyment and meaning to patients’ lives. Although a growing body of evidence supports the effectiveness of BA, enhancing the motivation and activity level of depressed patients is often challenging. In the present study, we explored the effectiveness of a brief BA treatment supported by virtual reality (VR) to facilitate the visualization and anticipation of four pleasurable activities that we tried to re-introduce in the patients’ daily routine. To do so, we conducted a single-case experimental de…
A Double Auction Mechanism for Virtual Resource Allocation in SDN-based Cellular Network
2016
The explosively growing demands for mobile traffic service bring both challenges and opportunities to wireless net- works, among which, wireless network virtualization is proposed as the main evolution towards 5G. In this paper, we first propose a Software Defined Network (SDN) based wireless virtualization architecture for enabling multi-flow transmission in order to save capital expenses (CapEx) and operation expenses (OpEx) significantly with multiple Infrastructures Providers (InPs) and multiple Mobile Virtual Network Operators (MVNOs). We for- mulate the virtual resource allocation problem with diverse QoS requirements as a social welfare maximization problem with transaction cost. Due…
