How multisensory experiences in virtual environments affect intention to return: The role of cognitive flexibility, sense of power and personality traits

The technology advances made every day are creating opportunities for business. Virtual Reality has been the focus of several studies. However, virtual reality has been stated to fail in implementing some senses, such as tactile, smell and taste. In this study, we cross two sensory experiences, one with the senses of sight and sound and the other with the sight, sound and smell. The experience takes place in a Virtual Café and measures the impact it has on the intention to return. The choice of the different sensory experiences was based on the concepts of proximal and distal senses. For the purposes of the study, this dissertation further analyses the concepts of Sense of Power and Cognitive Flexibility and Personality traits is introduced as a moderator in this relationship. The type of sensory experience is introduced and used as a moderator on the relationship between Sense of Power and Intention to Return (behavior). This study concludes that multisensory experiences in a virtual environment, have no impact on return intentions. However, this study also concludes that cognitive flexibility has a positive impact on sense of power and that personality traits plays as a moderator in the relationship between the two variables. Furthermore, this study findings suggested the notion that senses can be psychologically more proximal or distal based on the maximum physical distance typically required for a stimulus to be sensed also applies to virtual reality environments.Os avanços tecnológicos concretizados todos os dias estão a criar oportunidades para as empresas. A Realidade Virtual tem sido o foco de diversos estudos. Contudo, a realidade virtual tem sido apontada pela inexistência de alguns sentidos, tais como o tato, cheiro e paladar. Neste estudo, cruzamos duas experiências sensoriais, uma com os sentidos da visão e audição e a outra com os sentidos da visão, audição e cheiro. As experiências tomam lugar num café virtual e mede o impacto que tem na intenção de retorno (intention to return). A escolha das diferentes experiências sensoriais teve por base os conceitos de sentidos mais próximos e sentidos mais distantes. Para o objetivo desta tese, vão ser também analisados os conceitos de sentimento de poder e flexibilidade cognitiva e as características de personalidade são introduzidas como moderador desta relação. Posto isto, este estudo conclui que as experiências multissensoriais num ambiente virtual, não têm impacto na intenção de retorno. Contudo, o estudo conclui também que a flexibilidade cognitiva tem um impacto positivo no sentimento de poder e ainda que as características de personalidade têm um papel de moderador na relação entre os dois. Além disto, este estudo sugere que a ideia de que os sentidos podem ser psicologicamente mais próximos ou distantes, com base na distância física normalmente necessária para um estímulo ser sentido, também se verifica em ambientes de realidade virtual

The effect of multi-sensory cues on performance and experience during walking in immersive virtual environments

To examine the effects of multi-sensory cues during non-fatiguing walking in immersive virtual environments, we selected sensory cues including movement wind, directional wind, footstep vibration, and footstep sounds, and investigated their influence and interaction with each other. We developed a virtual reality system with non-fatiguing walking interaction and low-latency, multi-sensory feedback, and used it to conduct two successive experiments measuring user experience and performance through a triangle-completion task. We noticed some positive effects due to the addition of footstep vibration on task performance, and saw significant improvement in reported user experience due to the added wind and vibration cues
