Enhancing spherical photography with videogame visual effects in virtual reality experiences for users with limited mobility
Abstract
For people with a condition of disability, including those with limited mobility, accessing places of interest can be a challenge, affected by factors such as transportation distances, costs, and available infrastructure, among others. Inclusion is a current topic, as there is a need to provide and develop universal access. How can a virtual reality experience be developed to help disabled people experience public or private places of interest? To answer this question, we developed and tested an application for smartphones with virtual reality concepts. The application allows users to explore a sculpture museum, taking into consideration the context of the target group and the quality of a virtual reality experience. To test the application, we conducted a feasibility test with eleven patients with Parkinson's disease, who then responded to a survey with 57 questions. The test showed that users liked and found the application useful for bridging the gap for disabled persons in accessing culture through an enhanced photospheres virtual reality experience. The main contribution of this work is the design of an immersive user experience at low cost, with spherical pictures and effects inspired by game development
... This technology has several applications in different fields such as training [6], applications for people with special needs [7], education [8], and tourism [9,10], among others. ...
Virtual reality technology has grown significantly in recent years. The arrival of Head Mounted Displays (HDM) on the market for end-users has positioned these technologies as a new channel to promote new simulated or contextualized experiences. We have used the design and creation strategy to develop a virtual reality experience for the Oculus GO and Quest HDM. We digitized 30 pieces from nine local museums to provide an experience guided by a character that represents the main artisan work of the local region. A usability test was performed, showing that participants felt a high degree of immersion and realism. They were able to complete the assigned tasks, and results suggest that the software meets the main objective. Furthermore, the creation of this virtual reality (VR) experience has shown how important it is to make users a part of the creation process, as well as to develop a process to make the software useful to them and other users. Some recommendations are made based on the experience of the development, and comments are given on each step of the design and creation strategy.
摘 要
博物馆实践中的展示、教育、收藏、研究与观众服务,无不涉及身体本身与身体技术的概念化。博物馆本身的认知性积累及其物质形式,不但牵涉科学与文化的不同观点,也牵涉内在与外在、集体与个人、身体与灵魂之间互补性的二元区分。身体在博物馆中始终是一个不可或缺的重要维度。因此,本文旨在通过分析身体在博物馆中的基础作用来探讨未来博物馆以身体为中心的发展趋势,即从博物馆如何实现身体的在场出发,从博物馆物的历史文化实践性过渡到博物馆身体的社会属性,一直延续至当今虚拟技术视域下的博物馆具身化转向。
Chile ha reducido de manera acelerada sus niveles de pobreza, especialmente en áreas rurales. A lo anterior,se suman las transformaciones en diversos ámbitos que han experimentado los espacios rurales que han dadopaso a una nueva ruralidad. Este estudio permite cuantificar la importancia de estos cambios estructuralesacaecidos sobre las áreas rurales y urbanas para el período comprendido entre los años 2000 y 2011 sobre lareducción de la pobreza. Los resultados de esta investigación advierten un cambio profundo en la interacciónde los hogares rurales con su entorno.
This note addresses the confounding of the term 'presence' with several different distinct aspects of experience. Distinctions should be made between immersion, presence, involvement, emotional response, degree of interest. An analogy with colour science is pursued, specifically the difference between wavelength distribution and perception of colour-where the former is like 'immersion' the latter is like 'presence' (a human response). On top of this colours may be experienced as interesting, emotion-producing and so on. Just as the emotional experience engendered by a colour is not the same as the perception of the colour, which is not a simple function of the wavelength distribution, so involvement, interest or emotional response in a virtual reality is not the same as presence, which is not the same as immersion.
This paper demonstrates how physically disabled people can benefit from the innovative virtual reality techniques. Several specific examples show the applicability of virtual reality to the therapy and rehabilitation of people with various disabilities. In addition, the paper describes how physicians can use virtual reality as an advanced visualization tool for the diagnosis of physical disabilities. Finally, possible display techniques and input devices for diagnosis and rehabilitation purposes are discussed briefly.
A common measure of the quality or effectiveness of a virtual environment (VE) is the amount of presence it evokes in users. Presence is often defined as the sense of being there in a VE. There has been much debate about the best way to measure presence, and presence researchers need, and have sought, a measure that is reliable, valid, sensitive, and objective. We hypothesized that to the degree that a VE seems real, it would evoke physiological responses similar to those evoked by the corresponding real environment, and that greater presence would evoke a greater response. To examine this, we conducted three experiments, the results of which support the use of physiological reaction as a reliable, valid, sensitive, and objective presence measure. The experiments compared participants' physiological reactions to a non-threatening virtual room and their reactions to a stressful virtual height situation. We found that change in heart rate satisfied our requirements for a measure of presence, change in skin conductance did to a lesser extent, and that change in skin temperature did not. Moreover, the results showed that inclusion of a passive haptic element in the VE significantly increased presence and that for presence evoked: 30FPS > 20FPS > 15FPS.
This paper describes our recent experimental evaluation of Information-Rich Virtual Environment (IRVE) interfaces. To explore the depth cue/visibility tradeoff between annotation schemes, we design and evaluate two information layout techniques to support search and comparison tasks. The techniques provide different depth and association cues between objects and their labels: labels were displayed either in the virtual world relative to their referent (Object Space) or on an image plane workspace (Viewport Space). The Software Field of View (SFOV) was controlled to 60° or 100° of vertical angle and two groups were tested: those running on a single monitor and those on a tiled nine-panel display. Users were timed, tracked for correctness, and gave ratings for both difficulty and satisfaction on each task. Significant advantages were found for the Viewport interface, and for high SFOV. The interactions between these variables suggest special design considerations to effectively support search and comparison performance across monitor configurations and projection distortions.
