SECOND LIFE -A Paper Presentation on Virtual Reality

Our innovations have given us the power to transform our environment. Technologies have made this possible—from the simplest wooden plough to the most advanced personal computers. Throughout the journey of shaping the world, our technology went a long way in transforming our lives only physically but have you heard of a promising technology which brings about physical as well as mental transformations?. With the recent breakthrough in information technology, virtual reality has made it possible.

Virtual Reality is stimulating the user’s senses in such a way that a computer generated world is experienced as real. The computer presents the stimulating 3-D environment which creates sense of presence and deeply engaged by providing the interface using display devices like Head-Mounted Display (HMD), Binocular Omni-Orientation Monitor (BOOM), &Cave Automatic Virtual Environment (CAVE).The participant interacts with computer generated 3-D world through input devices like Data Gloves, Joysticks, Hand-Held Wands, & Body Sensors. Virtual world gives mental support to people with disabilities, cancer, AIDS, strokes, depression and other ailments, there by giving them second life. Its other applications include simulation of surgical incision, Virtual Prototyping, & Information Visualization. Thus, virtual reality brings the imagination as close and realistic as reality itself.

In short, virtual reality is the simulation of another world, the world in which the user can see through his own eyes, the world in which a user can experience his aspirations virtually and do it really, and the world which can be rightly called as his second life.

Multi Stage Car Parking System in a building

ABSTRACT:
One of the most important aspects of the transportation system is the accommodation of stationary motor vehicles: parking provision and its quality is crucial to the overall performance of the road, transport system. Unfortunately the failure in many communities to meet parking demand results in the development of several problems. Slow moving cars whose drivers are searching for parking places and drivers who do not know all possible alternatives regarding the best choice of car park or time of travel are common problems faced in urban road networks. Increased drivers stress and journey times, costs and energy consumption are frequent consequences.
In order to avoid these adverse effects we propose a multi stage car parking system in a private building using 8051 microcontroller, light sensors, seven segment display unit and motors, utilizing the concept of embedded systems. This system senses the car requiring parking slot, finds an empty slot in the parking building and transports the car to the appropriate slot through an automatic lift. In this way the problems of traffic jam and time delays are solved with implementation of separate building for parking.
