1 WIRELESS INTERACTIVE BOARD USING INFRARED AND BLUETOOTH TECHNOLOGY Froilan G. Destreza Master of Science in Computer Engineering ABSTRACT The methods of teaching and instruction in the academe have become more advanced and sophisticated since the advent of technology. The endless emergence of technology has made the researcher realize that he, too, can help in the improvement of teaching methodology in way that it will be more interesting. The study aimed to design, develop and evaluate a device which could be used in classroom discussions, presentations and reporting with the available technology in the market in terms of hardware and software. This study is a project development which followed the three stages such as, design, development and testing/evaluation. Three designs were drafted addressing the disadvantage of each; developed three prototypes out of those designs, and formulated a design algorithm for readily available software, which is iPen Suite. Through series of trials, the researcher identifies the best angle and distance to set up the project. First pen prototype can be set up at 30, 45, 60 degrees angles and at 2 and 3-meter distances. Second pen prototype and third pen prototype can be set up at 90 degrees angle and 2, 3 and 4-meter distances. There was no different in setting up the project in three tested environment; room, day and dim lights environment. The final product is accurate and smooth in 2- meter distance, 60 and 75 degrees angle of the infrared camera in relation to the board and can be set up in day light, room light and dim light environment with no difference. The project is more secured compared to the existing presenter; it uses a much later technology, and has the capability to be used for an interactive presentation. Keywords: interactive, wireless, infrared, Bluetooth INTRODUCTION In education, the methods of teaching and instruction have become more advanced and sophisticated since the advent of technology. Technologies such as computers, application programs and other devices are now widely used in the academe. The advancement of technology and other emerging technologies have gone almost beyond the realm of imagination. Man’s creativity and his ability to conceptualize and then turn those concepts to reality are being pushed to the limit; thus, every aspect of human life is touched one way or another by technology. As one type of technology becomes available another innovative product emerges. The seemingly endless emergence of technology has made the researcher realize that he too can help in improving teaching methodology in a way that it will be more interesting to students. He also believes that his concept will help in the advancement of information technology in a practical, affordable way. Being mindful of the students who are usually the audience in the teaching-learning process, the researcher conceived a developmental project that will make instruction interesting since it is interactive and will make use of advance technology. The project is entitled “Wir eless Interactive Board using Infrared and Bluetooth Technology.” METHODOLOGY The study is a project development. The researcher followed the three stages of development namely: design stage, development stage and testing and evaluation stage. Guided by the methodology of this type of study, the researcher conducted experiments and computed the needed values for the project. He gathered information; draw up designs, conducted tests and evaluation to make sure that the project would materialize into a realistic and reliable system. ANALYSIS OF RESULT The researcher determined the suitable wireless technology for the development of the project. The target of the researcher was to design and develop a device which could be used in classroom discussions, presentations and reporting with the available technology in the market. Combined with the software, iPen Suite was created as the middleware of the hardware and the computer system. Through a series of trials, the researcher successfully identifies the best angle and distance to set up the project. First pen prototype can be set up at 30, 45 and 60 degrees angles and at 2 and 3-meter distances. Second pen prototype and third pen prototype can be set up at 90 degrees angle and at 2, 3 and 4- meter distances. The researcher noticed that there was no difference in setting up the project in three tested environment: room light, day light and dim light environment. The researcher supported the experiment with computation of the y coordinate by using the angle of elevation computation (Stewart, J. et. al., 2006), angular diameter computation (Wikimedia, 2011), and the law of cosine computation (Stewart, J. et. al., 2006). Computing the angles with respect to the field of view of the infrared camera and the
