INTRODUCTION � Background The existence of sensor technology facilitate human to do something dangerous without directly having to do it, like extinguish fire. Besides that, sensor technology facilitate human in doing an observation in science. As it is automatic, sensor technology makes human be able to save energy and time. Sensor can work like human senses, even it is more accurate and faster than human senses. That’s why, the sensor technology is mostly used research.

INTRODUCTION � Problem Steatment The method used on the available application is a reflection method. The way of reflection method is emitting infrared rays which is reflected to the object, so infrared ray can be receive. On this research used method to determine the direction of object. The method used to determine object on this research is called pointing object method. As the problem on this research, namely : 1. What is the method object pointing using a back tracking algorithm can be used to determine the direction of the object with infrared sensors? 2. Whether in accordance with theory the development of methods to object pointing using back tracking algorithm can be applied to an object capture application?

INTRODUCTION � The Purpose The purpose of this research include : � 1. Proving that the method object pointing using back tracking algorithm with infrared sensors can be used to obtain the direction object. � 2. In accordance with theory object pointing method can be implemented on a simple application of object capture.

INTRODUCTION Scope Of this Research On this research is the beginning of the creation of a system using a object pointing method with infrared sensor, hence on this research were given a limit, namely : 1. Testing infrared sensor to obtain data in the from of emitting angle IR transmitter to use in developing methods. 2. Making algorithms to pointing object method. 3. Testing pointing object manually. 4. Analyzed testing and calculation data. �

THEORY LITERATURE � Infrared Sensor divided into 2 classification , those are : 1. Passive 2. Active IR transmitter � IR receiver �

THEORY LITERATURE � Basically the camera has the characteristics and differences in the shooting angle, namely as follows: 1. Straight Angle 2. Low Angle 3. High Angle

THEORY LITERATURE 1. Straight Angle The camera angles are normal. Usually used in the making of objects of the picture remains. 2. High Angle camera provides a view from the top down. Ordinary angle was used in the portrayal of the situation. The location of the camera position using the high angle higher than the object. The recommended angle not exceeding 45 degree, so as not to cause effects that are excessive. The ideal angle is between 50 -25 degree 3. Low Angle Camera angle on low-angle condition provides a view from the bottom / low in the direction of the object. Often used to put pressure on a person’s character or object. By placing the camera angle is lower than the object. The recommended angle is 45 degree. Meanwhile, to get the effect ideally beautiful object is the angle 10 -30 degree.

THEORY LITERATURE � High � Low Angle

RESULT & ANALYSIS

CONCLUSION The observation result, manually testing algorithm and result analysis from the testing can be obtained several conclusions as follows : 1. The design method of an object pointing using a backtracking algorithm can be used in infrared sensors. 2. The sensors can move based on infrared rays as the input signal. The sensor move finds the Infrared rays signal with following a signal which is transmitted infrared rays. 3. In accordance with theory about taking pictures with cameras and compared with the results of this study can be concluded that the method of pointing this object can be used to capture object. In accordance with theory about taking pictures with cameras and compared with the results of this study can be concluded that the method of pointing this object can be used to object capturing application.

FUTURE WORK � This observation are still many shortcomings and it has not become a complete system. Therefore, at the suggestion section on outlined a road map for a system that so from the results of this study, namely: 1. Testing methods used in manual (already done in this observation) 2. Testing method of automatically using the motor. Motor that can be used is the Stepper motor. The process of testing using this motor to obtain calibration data to determine the accuracy of motor movement. 3. Tests on the obstacles. The test is conducted to determine the influence of anything that may interfere with the infrared signal transmission to the recipient. 4. Find the maximum and minimum range of infrared rays 5. After doing the steps to obtain the data, then for the system to be implemented in applications using the additional microcontroller device.
