Abstract

This study addresses the critical ergonomic challenges faced by documentarians and content creators in mobile photography through the development of an innovative smartphone holder system. Through comprehensive mixed-methods research involving 100 general users and 20 expert photographers, key ergonomic deficiencies were identified, including hand tremors, inadequate camera control, and musculoskeletal discomfort during extended use. The iterative design process, grounded in user-centered design principles and ergonomic theory, resulted in a novel dual-grip smartphone holder featuring modular attachments and intuitive control mechanisms. Expert panel evaluation revealed substantial improvements across all performance metrics: 75% reduction in hand tremors, 50% enhancement in image stability, 43.5% increase in user comfort, 23.9% improvement in image quality, and 40% better control and maneuverability. The final design incorporates ergonomic optimization to minimize musculoskeletal strain, dual-grip functionality for versatile operation modes, and a modular attachment system ensuring broad equipment compatibility. This research contributes significant insights to human-computer interaction and industrial design fields, establishing a foundation for future developments in mobile photography accessories while emphasizing the critical importance of ergonomic considerations in contemporary content creation tools.
