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.

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 the 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.

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
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.

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 the 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 the 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. Microcontroller is
