Tracking natural walk is only feasible when the dimensions of the virtual environment match those of the real world. The problem of most navigation techniques is that they produce motion sickness because the optical flow observed does not match the vestibular and proprioceptive information that appears during real physical movement. Walk in place is a technique that can successfully reduce motion sickness without losing presence in the virtual environment. It is suitable for navigating in a very large virtual environment but it is not usually needed in small virtual spaces. Most current work focuses on one specific navigation metaphor, however in our experience we have observed that if users are given the possibility to use walk in place for large distances, they tend to switch to normal walk when they are in a confined virtual area (such as a small room). Therefore, in this paper we present our ongoing work to seamlessly switch between two navigation metaphors based on leg and head tracking to achieve a more intuitive and natural virtual navigation.","PeriodicalId":385751,"journal":{"name":"Spanish Computer Graphics Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132735350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Faced with increasingly demanding quality standards it is reasonable to address the transition from a manual inspection system to an automatic one using some advanced machine learning approaches such as deep learning models. However, the introduction of neural models in environments such as the manufacturing industry find certain impairments or limitations. Indeed, due to the harsh conditions of manufacturing environments, there is usually the limitation of collecting a high quality database for training neural models. Also, the imbalance between non-defective and defective samples is very common issue in this type of scenarios. To alleviate these problems, this work proposes a pipeline to generate rendered images from CAD models of industrial components, to subsequently feed an anomaly detection model based on Deep Learning. Our approach can simulate the potential geometric and photometric transformations in which the parts could be presented to a real camera to faithfully reproduce the image acquisition behavior of an automatic inspection system. We evaluated the accuracy of several neural models trained with different synthetically generated data set simulating different transformations such as part temperature or part position and orientation with respect to a given camera. The results shows the feasibility of the proposed approach during the design and evaluation process of the image acquisition setup and to guarantee the success of the real future application.

En este proyecto, ambas disciplinas han sido combinadas en el desarrollo de una aplicación móvil que permite, mediante el uso de un casco de realidad virtual, asistir a la reconstrucción del pterosaurio Tropeognathus mesembrinus, paseando a través de tres niveles anatómicos: el esqueleto, la musculatura y el aspecto externo. La reconstrucción culmina con una escena de Tropeognathus sobrevolando un paisaje del Cretácico Inferior. Además, incluye un visor 3D por el que se puede navegar por la anatomía del pterosaurio, así como una opción de poder mostrarlo en realidad aumentada al encontrar el logo del museo. En conclusión, esta aplicación supone una forma novedosa y atractiva de exponer una pieza paleontológica al público general, que podrá familiarizarse no sólo con Tropeognathus y los pterosaurios, sino también con el proceso de reconstrucción de la vida extinta.

Concretamente, el modelado de un entorno urbano con miles de ediﬁcios puede suponer un enorme reto si debe respetarse la información real del plano de la ciudad con manzanas, alturas de ediﬁcios reales, así como nombres de calles u otro tipo de información relevante. El objetivo ﬁnal es posibilitar la navegación libre por dicho entorno virtual ofreciendo al usuario la mayor sensación de realismo posible, independientemente del lugar exacto por donde decida moverse en la ciudad, y exista o no información de interés en dicha zona. A pesar de partir de toda la información posible disponible en un SIG urbano, éste no suele almacenar datos relativos al aspecto real de los inmuebles, lo cual resulta imprescindible para realizar un levantamiento realista de la ciudad completa. En este trabajo se propone una solución alternativa, aplicando texturas de forma automática a los ediﬁcios de los cuales no se tenga información exacta de su posible aspecto.
