Today, smartphones have become necessary because of their convenience and service. Despite all its benefits and advancement, mobile phone manufacturers have not yet designed a model suitable for the Filipino population, adversely affecting the user's health and comfort. The study aims to explore and recommend an ergonomic smartphone physical design that would cater to the perceived Filipino consumer preference to improve usability and user comfort. This study uses dimensions, luminous intensity, design attractiveness, screen, material, weight, design features, grip comfort, battery life, and actual product use to examine the perceived customer preference by disseminating a self-administered questionnaire. Using multivariate data analysis and structural equation modeling (SEM), the approach will enable the researchers to evaluate relationships between the ergonomic variables on the perceived customer preference of Filipino consumers and set standards for the physical design of smartphones for Filipino users. The results of this study identified that dimensions (DI), design attractiveness (DA), design features (DF), battery life (BL), and actual product use (APU) are the variables deemed to be significant to the perceived customer preference (PCP) of Filipino consumers.
