As a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. Today laptops are a great tool for education and learning, work and personal multimedia. Millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). Over the past several years, ...

background: with increased use of computers, exposure to electric and magnetic fields is increasing, the main objective of this study was to evaluate the electric and magnetic field strength in portable computers (laptops) and its relation with eyestrain users. methods: in this cross – sectional study, magnetic and electric fields in 125 laptop computers were measured from 30 cm and 50 cm dista...

The paper considers the level of the extremely low-frequency magnetic field, which is produced by the laptop computers. The magnetic field, which is characterized by the extremely low frequencies up to 300 Hz is measured due to its hazardous effects to the laptop user’s health. The experiment consists of testing 13 different laptop computers in normal operation conditions. The measuring of the ...

This research explores the effect of the use of laptop computers on students’ learning experiences during lectures. Our methodology involves embedding laptops with visualization software as a learning aid during lectures. We then employ a framework of seven principles of good practice in higher education to evaluate the impact of the use of laptop computers on the learning experience of compute...
