Welcome to Young Sang Choi's personal website

Young Sang Choi is a doctoral candidate of H. Milton Stewart School of Industrial and Systems Engineering at the Georgia Institute of Technology .

He is a member of the Healthcare Robotics Laboratory at the Health Systems Institute. Under academic advice of Dr. Charlie Kemp, he is studying human-robot interaction (HRI) issues in developing a robot El-E, pronunced as "Ellie", an assistive mobile manipulation robot designed to help people with motor impairments. He conducted an assessment of user needs from people with amyotrophic lateral sclerosis (ALS) who experience progressve degeneration of the muscle system to understand how the developed robot can fulfill the actual needs of daily lives of these people. He also designed and conducted human experiments testing the robot with the patients comparing three different alternative interface mechanisms to command the robot where the object is located.

Beyond HRI studies of designing and evaluating intelligent systems, his broader research interest includes human-computer interaction (HCI) in mobile devices, practices and psychology of product designers, and universal design for people with disabilities. Before his doctoral study at Georgia Tech, he worked as an embedded software engineer for Samsung Electronics, Korea developing software components for various products including mobile phones. He received his bachelors' and master's degree in Industrial Engineering at Seoul National University, Korea.
