Determination of Optimal Reading Conditions by Taguchi Method

Abstract

Computers are regarded as an indispensable part of daily and business life. In many occupations, people work by reading from computer screens. This study intends to identify the optimum environment conditions for reading on computer screens especially for academicians. To this end, light level, music level, and font size were accepted as the factors influencing reading, and four different levels were set for each. To identify the factor levels that maximize the reading speed, Taguchi method, which produces the optimal factor levels with minimum experiment, was used. L₁₆(4⁵) orthogonal experimental design was employed during the experimental studies, and the reading speed was selected as the performance measure. The results revealed that low light level, maximum font type size, and low music volume are the optimum reading conditions.

Optimal Okuma Şartlarının Taguchi Yöntemiyle Belirlenmesi

Abstract

Bilgisayarların günlük hayatın ve iş hayatının ayrılmaz bir parçası olduğu bilinmektedir. Birçok meslek grubunda insanlar bilgisayar ekranından metin okuyarak çalışmaktadır. Bu çalışmada, özellikle üniversitede çalışan akademisyenler için bilgisayar ekranından yapacakları okumalarda en iyi ortam şartlarının belirlenmesi amaçlanmıştır. Bu amaçla, bilgisayardan yapılan okumaları etkileyen üç unsur ışık seviyesi, müzik seviyesi ve punto büyüklüğü olarak ele alınmış ve her unsur için dört farklı seviye belirlenmiştir. Unsurların okuma hızını en yüksek yapacak seviyelerini belirlemek için az sayıda deneyle en iyi unsur seviyelerini tespit eden Taguchi Yöntemi tercih edilmiştir. Çalışma esnasında L₁₆(4⁵) ortogonal deney tasarım planı kullanılmış ve okuma hızı performans ölçütü olarak belirlenmiştir. Elde edilen sonuçlara göre ekran ışık seviyesinin hafif, punto büyüklüğünün en fazla ve müzik seviyesinin hafif olduğu ortamın yapılacak okuma çalışması için ideal olduğu anlaşılmıştır.
