Developing a FPGA-supported touchscreen writing / drawing system for educational environments

📝 Abstract

Developments in information and communication technologies have been greatly influential on the practices in all fields, and education is not an exception to this. To illustrate with, computers were first used in computer assisted education in order to increase the efficiency of teaching process. Recently, computer has contributed more to the field through interactive and smart class applications that are specially designed for classroom use. The aim of this study is to develop a low cost, portable and projection supported touchscreen to be used in educational environments by using FPGA technology and to test its usability. For the purposes of the study, the above mentioned system was developed by using the necessary hardware and software, and later it was tested in terms of usability. This usability test was administered to teachers, who were the target end users of this touchscreen writing / drawing system. The aim of this test was to determine user friendliness, subservientness and usability of the system. Several tools were used to obtain data from the users that participated in the study. The analysis and evaluation of the data collected revealed that the system has achieved its objectives successfully.

Abstract

Developments in information and communication technologies have been greatly influential on the practices in all fields, and education is not an exception to this. To illustrate with, computers were first used in computer – assisted education in order to increase the efficiency of teaching process. Recently, computer has contributed more to the field through interactive and smart class applications that are specially designed for classroom use. The aim of this study is to develop a low – cost, portable and projection – supported touchscreen to be used in educational environments by using FPGA technology and to test its usability. For the purposes of the study, the above mentioned system was developed by using the necessary hardware and software, and later it was tested in terms of usability. This usability test was administered to teachers, who were the target end – users of this touchscreen writing / drawing system. The aim of this test was to determine “user – friendliness”, “subservientness” and “usability” of the system. Several tools were used to obtain data from the users that participated in the study. The analysis and evaluation of the data collected revealed that the system has achieved its objectives successfully.

1. INTRODUCTION

Education has always been a field of study making use of technology as effectively as possible. Today’s popular concept “educational technologies” has been derived from “the process of benefiting from the advantages provided by technology as much as possible in order to increase the effectiveness and efficiency of teaching process and educational studies. In other words,

Develop. a FPGA – Supported Touchscreen Writing / Drawing System for Educ. Env. – Tufekci, A., Samanci, K. & Kose, U. educational technologies (also called teaching technologies) are defined as “the studies and ethical applications ensuring facilitated education and increased performance by effectively using, managing and developing appropriate technological processes and resources (Richey, 2008).
Technology has always supplemented educational practices in several ways. It is clear that extending and introducing these practices to larger audiences, presenting visual simulations and graphic supports for students, developing various audio – visual educational materials and introducing many evaluation systems and tools result in more efficient and easier educational processes. Similarly, the findings of the studies conducted in educational technologies are to a great extent reflected in real classrooms in the form of practical applications. To illustrate with, many technological tools and devices, most of which are computer – supported, are used for educational processes in real classroom environments. It is also true that almost all the educational materials used in today’s classrooms are computer – controlled or computer – operated. Therefore; thanks to computer support, classrooms have now acquired “smart classroom” features. Depending on the developments in computer technology, the users (students or teachers) have started to interact with the devices available in classrooms, which have inevitably led to the emergence of the concept “interactive classroom” as the “next generation” version of “smart classrooms”.
In interactive classrooms, there is an ongoing direct interaction between the users and the system, and this process requires a computer enabling this interaction. The studies conducted on this issue show that almost all interactive classroom applications require the use of at least one computer. Thus, the dense use of computers has become inevitable in educational processes just like in every field of life. Used for measurement and evaluation purposes at the beginning, computers later have been used in computer – assisted teaching intensively as well (Dogan, 1997). The most recent example of this new function of computers is computer – supported board, which is also called “smart board”. The system is fully controlled by a computer, and the texts and visuals are projected on a board via a pro
