An overview on virtual reality and its history,types of VR,Architecture and various applications of it.It contains Current problems and future works as well.
Virtual reality is, plainly speaking, seeing an imaginary world, rather than the real one. Seeing, hearing, smelling, testing, feeling. The imaginary world is a simulation running in a computer. The sense data is fed by some system to our brain.
Virtual reality (VR) is a computer technology that uses Virtual reality headsets, sometimes in combination with physical spaces or multi-projected environments, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment. A person using virtual reality equipment is able to "look around" the artificial world, and with high quality VR move about in it and interact with virtual features or items. VR headsets are head-mounted goggles with a screen in front of the eyes. Programs may include audio and sounds through speakers or headphones.

Virtual Reality refers to a high-end user interface that involves real-time simulation and interactions through multiple sensorial channels. Virtual reality is also known as Artificial Reality. It us often referred as VR/AR. Virtual reality includes Augmented reality, Windows on web, Immersive VR, Telepresence, Mixed Reality(Augmented Reality), Distributed VR.
Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality can include entertainment (i.e. video games) and educational purposes (i.e. medical or military training). Other, distinct types of VR style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR.
Virtual Reality refers to a high-end user interface that involves real-time simulation and interactions through multiple sensorial channels. Virtual Reality is often used to describe a wide variety of applications, commonly associated with its immersive, highly visual, 3D environments. The development of CAD software, graphics hardware acceleration, head mounted displays, database gloves and miniaturization have helped popularize the concept. Jaron Lanier coined the term Virtual Reality in 1987. Today Virtual Reality plays a big part in the everyday lives of the world’s population.
this presentation covers the very aspects of creating the virtual environments and also gives a small tutorial on how to create AR apps to create custom synthetic environments.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

the physical world which become in a sense an equal
part of our natural environment.
12. Types of VR system(cont’d)
• Video Mapping VR
− The user watches a monitor that
shows his body's interaction
with the world.
− The element of interaction
depends on a number of factors
like speed, range and mapping.
13. Types of VR system(cont’d)
• Distributed VR
– A simulated world runs on several computers which
are connected over network and the people are able
to interact in real time, sharing the same virtual world.
15. Technologies of VR--Hardware
