«Методика создания фрактального стереоконтента для автономных шлемов виртуальной реальности»
The article describes experiments to determine the system of optimal synthesis parameters for fractal and mixed content that meets the requirements of its comfortable viewing in stand-alone helmets of virtual reality.
Iterated function systems (IFS) are interesting parametric models for generating fractal sets and functions. The general idea is to compress, deform and translate a given set or function with a collection of operators and to iterate the procedure. Under weak assumptions, IFS possess a unique fixed point which is in general fractal. IFS were introduced in a deterministic context, then were generalized to the random setting on abstract spaces in the early 1980s. Their adaptation to random signals was carried out by Hutchinson and Rüschendorff by considering random operators. This study extends their model with not only random operators but also a random underlying construction tree. We show that the corresponding IFS converges under certain hypothesis to a unique fractal fixed point. Properties of the fixed point are also described.
In the contemporary world where social media became one of the key sources of information about offline reality, a rally can be performed without even leaving your house. That is why the discussion participants and the audience reflect on the problem of ‘authenticity' of the virtual reality and political actions it provides. The users ponder the question whether virtual activism is relevant, what conditions make virtual political action ‘real' and ‘accomplished', i.e. they try to define the status of virtual reality and the boundaries between the ‘real' and the ‘virtual', the ‘original idea' (in E. Goffman's words) and the ‘falsifi cation'. This reframing results in a redef inition of what activists, city inhabitants and lawenforcementbodies considerto be a ‘political action'. The article considers how the perceptions of social media activism change and to what conflicts those changes can lead.
In the early 1990s, a small group of individuals recognized how virtual reality (VR) could transform medicine by immersing physicians, students and patients in data more completely. Technical obstacles delayed progress but VR is now enjoying a renaissance, with breakthrough applications available for healthcare.
This book presents papers from the Medicine Meets Virtual Reality 22 conference, held in Los Angeles, California, USA, in April 2016. Engineers, physicians, scientists, educators, students, industry, military, and futurists participated in its creative mix of unorthodox thinking and validated investigation. The topics covered include medical simulation and modeling, imaging and visualization, robotics, haptics, sensors, physical and mental rehabilitation tools, and more.
Providing an overview of the state-of-the-art, this book will interest all those involved in medical VR and in innovative healthcare, generally.
Human communication is basically the exchange of information. How can this be realized? Each communicant proceeds from a subjective perception of an objective reality; however in order to exchange information relating to this reality communicants are obliged to coordinate their perceptions. Each of us entertains personal experiences based on individual impressions and associations. But communication presupposes the presence of a common experience and the possibility of the coordination of subjective perceptions. It is presumed that communicants share common experiences: this seems to be the natural premise of communication.
How is this possible? How can I be certain, for example, that my interlocutor understands the words in the same way I do? How can we correlate our understanding? It seems obvious that the necessary condition of communication is an agreement between the communicants. But how can this agreement be reached? Where is the initial point of the coordination of individual experience of different persons?
The present book deals with this and related questions. Special attention is given to the role of deixis in the process of communication and to the mechanisms of linguistic comprehension.
