Virtual Reality In Cognitive Psychology

Improved Essays
There are many research studies that have been conducted for examining the effect of Virtual Reality Environments. A number of them are also related to cognitive psychology. Some of the studies related to the analysis of the virtual reality effect on cognitive psychology are mentioned briefly.
Sutherland I.E.in 1965, the very first idea of Virtual Reality was presented by Ivan Sutherland “make that (virtual) world in the window look real, sound real, feel real and respond realistically to the viewer’s actions”. It made fundamental contributions in the area of human-computer interaction, being one of the first graphical user interfaces. It exploited the light pen, the predecessor of the mouse, allowing the user to point at and interacts with

Since the technology provides different types of sources for visual perception, the effectiveness and efficiency of visual and cognitive tasks in these simulated environments can be affected either in a positive or a negative way. To understand these effects, it’s necessary to examine our visual perception and the mechanisms of human cognitive in virtual environments. The earlier paper-pen test was used for psychological tests like attention process, workload etc.
• With the advancement of technology, various computer- based test batteries like VTS (Vienna test system), WAIS, CPI etc. have been

Virtual reality is experienced through two senses out of five those are sight and sound. Virtual Environments are new types of human-computer interaction interfaces which help the users to perceive and act in a three-dimensional virtual world. A 3-D image is the simplest form of virtual reality. The 3-D images can be explored efficiently with the help of the computer, usually by keyboard keys or by using the mouse, so that the content of the image can be movable in some direction or zooms in or out (Roy, S.,2003). Wearable computers and Haptic devices help in making virtual reality more sophisticated and realistic. The user experiences the 3D world from the first person point of

    A 3D presentation allows the user to fully grasp the scope of work if they are allowed to flow through the space. Traditionally it has started with creating a 3D model and presenting rendered scenes. From there it had progressed from scenes to automated walk-throughs. Now with today’s technology the user has the ability to immerse themselves into the model and fully experience their project with the use of virtual reality. There are two kinds of approaches to VR presentations: immersive and non-immersive.…

    1 INTRODUCTION Virtual Reality is a way for humans to visualise, manipulate and interact with computers and highly complicated data (Kushner 2016). In addition, this visualisation refers to the computer developing visual, auditory and other sensual outputs to the user of a world within the computer (Kushner 2016). Also, this world may be scientific simulation, or a look into a database, the user is able to collaborate with the world and directly manipulate objects within the world, where some worlds will be animated by processes, either by physical simulations or simple animation scripts (Stevens 1995). Therefore, interaction within the virtual world is a demanding test for a virtual reality, in this essay, a brief history of virtual…

    Now thoughtful and innovative designs are available to the textile designers and textile manufacturers at the click of a mouse. When the products in pre-manufacturing stage are designed with the help of computer-based tools, it is termed as CAD or Computer-aided design. Sometimes the acronyms such as CADD or CAID are also used which stand for "Computer-aided design and drafting" and “Computer-aided Industrial Design” respectively. These terms are mostly used in the sectors related to the manufacturing of engineering goods. As far as textile industry is related, CAD is generally used for interpreting computerized designing.…
