The intelligent wireless video camera described in this paper is designed using wireless video monitoring system, for detecting the presence of a person who is inside the restricted zone.  This type of automatic wireless video monitors is quite suitable for the isolated restricted zones, where the tight security is required.

The principle of remote sensing is utilized in this, to detect the presence of any person who is very near to reference point with in the zone.

A video camera collects the images from the reference points and then converts into electronic signals.  The collected images are converted from visible light into invisible

electronic signals inside a solid-state imager.  These signals are transmitted to the monitor,

In this paper for the demonstration purpose three reference points are taken.  Each reference point is arranged with two infrared LED’s and one lamp.  This arrangement is made to detect the presence of a person who is near the reference point.   The reference point is nothing but restricted area, when any person comes near to any reference point, then immediately that particular reference point output will become high and this high signal is fed to the computer.   Now the computer energizes that particular reference point lamp and rotates the video camera towards that reference point for collecting the images at that particular reference point. To rotate the video camera towards interrupted reference point, stepper motor is used.   

ABSTRACT

              "HAPTICS”-- a technology that adds the sense of touch to virtual environment .Haptic  interfaces allow the user to feel as well as to see virtual objects on a computer, and so we can give an illusion of touching surfaces, shaping  virtual clay or moving objects around.

               The sensation of touch is the brain’s most effective learning mechanism --more effective than seeing or hearing—which is why the new technology holds so much promise as a teaching tool.

               Haptic technology is like exploring the virtual world with a stick. If you push the stick into a virtual balloon push back .The computer communicates sensations through a haptic interface –a  stick, scalpel, racket or pen that is connected to a force-exerting  motors.

               With this technology we can now sit down at a computer terminal and touch objects that exist only in the "mind" of the computer.By using special input/output devices (joysticks, data gloves, or other devices), users can receive feedback from computer applications in the form of felt sensations in the hand or other parts of the body. In combination with a visual display, haptics technology can be used to train people for tasks requiring hand-eye coordination, such as surgery and space ship maneuvers.

                In this paper we explicate how sensors and actuators are used for tracking the position and movement of the haptic device moved by the operator. We mention the different types of force rendering algorithms. Then, we move on to a few applications of Haptic Technology. Finally we conclude by mentioning a few future developments.
