Optimal laptop VDU parameter setting using Taguchi method

Abstract

This paper shows that the Taguchi method of optimization can be easily used in optimizing the visual display unit (VDU) parameters for maximizing the readability on the laptop. Researchers use five factors, each at three levels which are font size, font style, line spacing, viewing distance and screen inclination angle with reading time in seconds (for reading about 300 words) as the response variable. Other parameters like text/background color combination (black/white), table height, illumination etc. were kept constant. Experiments were conducted by varying different parameters on the basis of L27 orthogonal array design. Results show that there is a 15.3% decrease in mean reading time when working at optimal condition. Results also show that factor A is the most important factor which is font size followed by factor C (line spacing), factor E (screen inclination angle), factor D (viewing distance) and factor B (the font style) which is the least important factor.Growing Science Ltd.

“…Before conducting the study, an application was sent to and approved by the Institutional Review Board (IRB) to ensure that the necessary steps were taken to protect the rights of The laptop was physically set up at 40 cm from the edge of the table with a screen inclination angle of approximately 105°to allow for consistency among participants (Gangele & Mishra, 2015). All participants then gained "experience" with the LEP by completing the pretest presentation.…”
