International Journal of Engineering and Technical Research (IJETR) ISSN: 2321-0869, Volume-2, Issue-9, September 2014 Abstract— A gesture is a form of non-verbal communication in which visible bodily actions communicate with some specific messages, in place of speech or with combination of words. Gestures is movement of the hand, face or any other parts of our the body. Gestures is different from physical non-verbal communication which actually do not communicate a specific message .The gesture movements can be used to interact with the technology like computers, using touch or multi-touch popularized by the iPhone, physical movements detection and capturing of visual motion, used in video game consoles .Human Computer Interaction(HCI) plays a vital role in day to day activities. Use of computer vision has taken HCI to an altogether different level. In this project, simple potentiometers are used for tracking hand movements to control mouse pointer. The features to be detected include hand movement. Our objective is to implement all the mouse tasks without the use of mouse. . Index Terms—Gesture, interaction with technology, potentiometers, implementation of mouse I. INTRODUCTION In this paper the result of the work done in development of "Hand Gesture Controlled Mouse" operated wirelessly is discuessed. The objective is to design a equivalent model of mouse which can be operated wirelessly and control mouse actions using hand gesture recognition. This project can be used with great versatility in day to day life. The transmitter model takes data from potentiometer sensor, encode it and sends using Radio-Frequency transmitter 434MHz. The Radio-Frequency receiver receives data and amplifies it. This data is then sent to PC for mouse controlling action according to data received. The data is decoded using proper decoding technique. According to data received the mouse pointer Manuscript received September 13 , 2014. Pankaj P Kolhe, Department of Instrumentation Engineering, S.G.G.S.

Then its features can be detected using different logic. Finally the features extracted are used for making gestures recognized by a system as input. In this project, the designed system is capable of identifying three different gestures. To make sure that only one of the three required tasks is performed, at that particular instant. Proper entry and exit conditions in the state machine ensure smooth functioning of the gesture recognition system .The ability to track a person's movements and determine what gestures they may be performing can be achieved through different tools .Although there has been a large amount of researches in image/video based gesture recognition, there is some variation in the tools and environments used between implementations. II.HAND GESTURE MOUSE CONTROLLING A. Arrangement of potentiometric sensors Fig.1.Potentiometric arrangement The arrangement of potentiometric sensors, play a vital role in development of this project. A perpendicular arrangement of the potentiometric sensors shown in Fig.1 is made in order to scan the exact position of hand in xy-plane. The third sensor is placed on the hinge of the arm to locate the movement of arm in z plane. The potentiometric sensors are used as voltage divider circuitry, which supply the dc voltage from voltage divider circuitry to the analog input pins of the ATmega328p IC. B. Symmetric-key cryptography We used symmetric key cryptography to encode the data to be transmitted wirelessly in order to reduce the data losses caused due to the transmission media and it also keeps a check while decryption that the correct data gets extracted. The 10 bit data from ADC was split into 2, 5 bit data and added 3 bit encryption to make 1 www.erpublication.org POTENTIOMETRIC SENSOR BASED 3-D MOUSE CONTROL Pankaj P Kolhe, Mahesh N.
