The current study derived seven descriptors from the pixel matrix of 5401 Chinese characters in the commonly used Ming, Kai, Li, and Hei fonts. A factor analysis was used to reduce the number of descriptors for a validation experiment. The three-factor solution (number of strokes, character height, and character width) explaining 89.54% of the variance was(More)
This paper represents the results of an anthropometric measurement of the isometric muscle strength of Chinese young males in Taiwan aged from 16 to 20 years. The study uses a sample of 120 male students and measures four types of muscle strength: (1) right arm strength in exerting pull, push, adduction, abduction, lift, and press directions with five elbow(More)
The study derived seven descriptors from the pixel matrices of both the uppercase and lowercase forms of the 26 letters in the English alphabet in the regular and italic versions of the most commonly used font, Times New Roman. A factor analysis of the seven descriptors showed that a two-factor solution of letter width and height explained 76.6% of the(More)
Recent advances of the broadband Internet and multimedia environment let web users demand from web pages not only cognitive usability but also related feelings. Drawing on existing theories of cognitive psychology and human–computer interaction, a research model has been developed to explain the relationship between the visual factors and aesthetic(More)
Sleep quality is an essential factor to human beings for health. The current paper conducted four studies to provide a suitable pillow for promoting sleep quality. Study 1 investigated the natural positions of 40 subjects during sleep to derive key-points for a pillow design. The results suggested that the supine and lateral positions were alternatively 24(More)
The study presents a simple method to predict the drawing performance of designers or artists by measuring the stability of their line drawings. An 8 x 3 two-way factorial design experiment with directions and phases was conducted to explore the most stable direction and phase among eight directions and three phases of line drawing. The scores of 40(More)
