SUMMARY:Effects of Glass Transmittance, Font Brightness and Font Size on T
 ext Legibility in LCD Home Appliance Interface
DESCRIPTION:Lecture\n\nMinjoon Sohn, San Hong, Namhee Kim, Sungwoo Jeong, 
 and Woojin Park (Seoul National University)\n\nThis study experimentally i
 nvestigated the impacts of major design variables of a liquid crystal disp
 lay (LCD) home appliance control interface on interface text legibility. T
 he home appliance of interest was a washing machine. \n\nThe experimental 
 setup simulated a real-world washing machine usage condition challenging i
 n terms of visual information processing. Independent variables were surfa
 ce glass transmittance (25%, 50%, and 75%), font brightness (25cd/m², 44cd
 /m², and 90cd/m² at 60%, 75%, and 100%), and font height (3mm, 5mm, and 7m
 m). Response time (RT) and proportion of errors (PE) were employed as the 
 dependent measures. Regression analysis was conducted to analyze data. \n\
 nThe results showed that: 1) an increase in the font height resulted in de
 creases in RT and PE, and 2) increasing glass transmittance and font brigh
 tness reduced RT and PE for the 3 mm and 5 mm font heights. The study find
 ings would inform the design of home appliance control interfaces.\n\nTrac
