Museos virtuales y entorno construido: narrativas y experiencias inmersivas vía centros de geodatos multitemporales

[EN] Our built environment is nowadays considered as a dynamic complex, stretching and transforming across space and time, with the interaction of human, social and economic dimensions. It needs to be safeguarded as living places for the future taking into account such complexity. The general aim of this work is to contribute to the comprehension of landscape values, enhancing participation processes by tourists and local communities, considering the built environment as a system: the sum of natural transformation, ancient artefacts stratification and human activities, partially covering the tangible traces, and functioning as a vehicle for the comprehension of intangible values. Multi-temporal, multi-scale and geospatial datasets can play an important role in such knowledge transfer processes by means of narratives and immersive experiences in a multimedia museum approach. In particular, the cartographic heritage, in the form of metric and non-metric maps, can be progressively used as a source of information for innovative narratives. Virtual Museums (VMs)are additional "channels" to disseminate content and to provide knowledge about cultural heritage; they have emerged from the crossbreeding process between museums and digital technologies. Investigating how digital storytelling may support communication and understanding of complex systems, such as the built environment and landscape, it is relevant because cultural awareness may foster the sense of belonging and identity construction of which Europe is thirsty, contributing to the safeguarding of fragile sites. The paper provides useful information for museums that would like to follow this pathway. It retraces the main steps of storytelling production and presents interesting examples of immersive narrative models based on geospatial data and a virtual hub, helping people to retrieve and access information and to recognize places of memory mostly unknown. Moreover, it offers an evaluation of existing tools that can be adopted for this purpose. Eventually, by virtue of the research carried out for the case study of the Virtual Museum of Como Lake Landscape, the paper aims at ascertaining which kind of stories and experiences can be designed, the potential of these tools and possible weaknesses or constraints that deserve future researches.[ES] El entorno construido se considera hoy en día como un complejo dinámico, que se extiende y transforma a través del espacio y el tiempo, con interacción de dimensiones humanas, sociales y económicas. Debe salvaguardarse como lugares donde vivir el futuro teniendo en cuenta tal complejidad. El objetivo general de este trabajo es contribuir a la comprensión de los valores paisajísticos, potenciando los procesos de participación de los turistas y de los autóctonos, considerando el entorno construido como un sistema: suma de la transformación natural, de la estratificación de artefactos antiguos y de actividades humanas, cubriendo parcialmente los rastros tangibles, y vehículo de comprensión de valores intangibles. Los conjuntos de datos multitemporales, a multi-escala y geoespaciales pueden desempeñar un papel importante en dicho proceso de transferencia de conocimiento a través de narrativas y experiencias inmersivas en el enfoque de un museo multimedia. En particular, el patrimonio cartográfico, en forma de mapas métricos y mapas no métricos, puede utilizarse progresivamente como fuente de información para narrativas innovadoras. Los Museos Virtuales (VM) son “canales” adicionales que permiten difundir contenido y proporcionar conocimiento sobre el patrimonio cultural; surgen del proceso de mestizaje entre museos y tecnologías digitales. Investigar cómo la narración digital puede apoyar la comunicación y la comprensión de sistemas complejos, como el entorno construido y el paisaje, es relevante porque la conciencia cultural puede fomentar el sentido de pertenencia y la construcción de identidad de los que Europa tiene sed, contribuyendo a la protección de sitios frágiles. El artículo proporciona información útil para los museos que deseen seguir este camino. Describe los principales pasos que deberían considerarse a la hora de producir narrativas y pone ejemplos interesantes de modelos narrativos inmersivos basados en datos geoespaciales y centros virtuales, que ayudan a las personas a recuperar y acceder a información, y a reconocer lugares desconocidos o vagamente retenidos en la memoria. Además, ofrece una evaluación de las herramientas existentes que se pueden adoptar con este propósito. El objetivo es aclarar, finalmente, en virtud dela investigación desarrollada en el caso de estudio del Museo Virtual del Paisaje del Lago di Como, qué tipo de historias y experiencias se pueden diseñar, el potencial de estas herramientas y las posibles debilidades o limitaciones que merecen futuras investigaciones.We thank Stefano Della Torre (Head of Polimi dABC) as Sc.

The History and Evolution of North American Ski Resort Map Style and Design

The first official ski resort in North America opened to the public in 1936 in Sun Valley, Idaho. Today, there are over 400 resorts across the continent in constant competition with one another for customers. Ski maps were first introduced as navigational tools, but quickly became a means for advertising what the resorts had to offer. The desire to outshine rival resorts has produced thousands of unique ski maps over the years, forming a collection of maps that has never been comprehensively analyzed until now. The first phase of the thesis involved the gathering of historical and modern ski maps to be examined and catalogued into a database. A total of 1,779 maps were archived along with relevant attribute information concerning the style and design of each map. This database, in addition to interviews with key informants and historical texts, helps to provide a complete picture of North American ski mapping history for the first time. The second phase of the thesis was a quantitative survey of skiers and snowboarders to assess users’ impressions and satisfaction levels of modern ski maps. Several examples of ski maps were presented to the survey respondents, and they were asked to provide their opinions and concerns about the overall appearance of the map. It was found that most respondents preferred the traditional painted panoramic style over other styles of printed ski maps, and many were hesitant about the effectiveness of newer mobile ski mapping alternatives. While it appears that printed maps are around to stay for now, the recent retirement of prominent ski map painter James Niehues may signify the demise of traditionally hand-painted ski resort maps. Extensive literature already exists regarding the reproduction of hand-painted panoramas using computer software programs, and as the digital image becomes more accepted in our culture it is possible that many future ski resort maps will be digitally-rendered

Bar Harbor Project Center Trail View: Acadia National Park

Acadia National Park is home to over 125 miles of highly visited trails in coastal Maine. A pressing goal of the park is nature preservation and public outreach. The goal of the Trail View project was to document and make these trails more accessible using 360-degree panoramic photos. These photos were compiled and geotagged to be assembled online in virtual tours. This allows potential hikers and people with disabilities to view the trails. Previous WPI Trail View teams have demonstrated proof of concept, completing 7.2 miles of trails. Building on their foundation, this year’s team used cameras that captured 360-degree photos. Using this method, 64.6 miles of trails were recorded. These trail views will be made available on the Acadia National Park website

Mapping speditivo da sensori mobili per il controllo della conservazione dei valori paesaggistici del territorio. Quick mapping by mobile sensors for landscape values monitoring and conservation

Geomatics researches, applied to architecture and landscape, are becoming increasingly focused on development of innovation in survey techniques and digital data management. Quick techniques are sought, with a high level of automation and versatility, to support knowledge management and protection of cultural heritage, be it referred to artistic and architectural heritage or, overall, to whole varied landscape assets, in so such highest density in the country as to consider Heritage itself. The investigation and conservation initiatives in the field of landscape heritage must constantly deal with many conditions of risk exposure, and that is not always possible to make up with preventive protection, whether if it is a constant risk like that intrinsic to the status of the property, or sudden and unforeseen risks, or if it is only partially predictable, determined by an environmental emergency. In these test-sites, which have a typical vulnerability resulting from their intrinsic conditions of exposure to risk, is interesting to experiment and combine technological research with the public interest for the protection and preservation of the value of the asset. This paper is intended for the testing of systems for the expeditious acquisition of spatial data in a outstanding test site, an area of the Cinque Terre, devastated by the flood of autumn 2011 Le ricerche della Geomatica applicata all’Architettura e al paesaggio, sono mirati sempre più allo sviluppo dell’innovazione nel campo delle tecniche di acquisizione dei dati e della loro gestione digitale; si ricercano metodi speditivi, con elevati gradi di automazione e versatili, per il supporto alla gestione della conoscenza e della tutela del patrimonio culturale, che sia esso riferito ai beni artistico-architettonici o in senso più ampio all’insieme variegato dei beni paesaggistici, ad elevatissima densità nel territorio nazionale tanto da considerarlo Patrimonio esso stesso. Le indagini e le iniziative di conservazione in materia di patrimonio paesaggistico devono costantemente fronteggiare le innumerevoli condizioni di rischio cui esso è esposto, e cui non sempre si riesce a sopperire con una tutela preventiva. sia esso un rischio costante come quello intrinseco allo status del bene, oppure rischi improvvisi e imprevedibili, o solo parzialmente prevedibili, determinati da una emergenza ambientale. E’ in questi test-site, che possiedono una tipica vulnerabilità derivante dalle loro intrinseche condizioni di esposizione al rischio, che risulta interessante sperimentare e combinare la ricerca tecnologica con l’interesse collettivo di tutela e conservazione del valore del bene stesso. Il presente contributo ha per obiettivo la sperimentazione di sistemi speditivi di acquisizione dei dati spaziali in un test site d’eccezione, un’area delle Cinque Terre devastata dall’alluvione dell’autunno 2011

3D virtual geology field trips: opportunities and limitations

As a part of The OpenScience Laboratory (http://www.open.ac.uk/researchprojects/open-science/), we have developed a virtual Geology field trip in a three-dimensional (3D) environment (https://learn5.open.ac.uk/course/format/sciencelab/section.php?name=skiddaw_1), using the Unity 3D software (https://unity3d.com/). The learning activities within this 3D application are designed to mirror the experience of a field trip in the Skiddaw mountains of UK’s Lake District. The primary objective of developing an authentic 3D avatar-based interactive environment has been to provide an immersive experience to the users through sense of space. The application is based around a 10km x 10km low to medium detail model of the terrain around Skiddaw with overlaid photogrammetry-derived mesh and textual imagery, and augmented with in-built Unity terrain and flora. The virtual embodiment in the form of avatars and the multi-user environment give a sense of co-presence and provides opportunities for collaborative learning. In this presentation, we will reflect on the design and development process of the 3D App: how the pedagogical aspects of Geology and fieldwork were integrated with the affordances of 3D environments and the capabilities of Unity 3D, the development platform. We will discuss the interaction design of the 3D App including its navigation and wayfinding aspects that provide a sense of presence, sense of place, and an immersive learning experience for the students. We will analyse the pedagogical design of the 3D App to highlight the spatial and contextual learning opportunities for the students. With this Virtual Skiddaw App as an example, we will reflect on the following: a) opportunities offered by 3D virtual field trips for science education in both schools and higher education; b) comparisons (advantages and obstacles) of the 3D experience with 2D field trips (for example, via the websites or DVDs) – for example, the real-time multi-user interactions offered by a 3D environment and their impact on learning and student engagement; and c) limitations of 3D virtual field trips with respect to real world field trips

Visual Distortions in 360-degree Videos.

Omnidirectional (or 360°) images and videos are emergent signals being used in many areas, such as robotics and virtual/augmented reality. In particular, for virtual reality applications, they allow an immersive experience in which the user can interactively navigate through a scene with three degrees of freedom, wearing a head-mounted display. Current approaches for capturing, processing, delivering, and displaying 360° content, however, present many open technical challenges and introduce several types of distortions in the visual signal. Some of the distortions are specific to the nature of 360° images and often differ from those encountered in classical visual communication frameworks. This paper provides a first comprehensive review of the most common visual distortions that alter 360° signals going through the different processing elements of the visual communication pipeline. While their impact on viewers' visual perception and the immersive experience at large is still unknown-thus, it is an open research topic-this review serves the purpose of proposing a taxonomy of the visual distortions that can be encountered in 360° signals. Their underlying causes in the end-to-end 360° content distribution pipeline are identified. This taxonomy is essential as a basis for comparing different processing techniques, such as visual enhancement, encoding, and streaming strategies, and allowing the effective design of new algorithms and applications. It is also a useful resource for the design of psycho-visual studies aiming to characterize human perception of 360° content in interactive and immersive applications
