TITLE: Smartphone Usage Pattern and Addiction Probability: A Comparative Analysis between U.S. and Korea AUTHORS:

As cell phones evolve into mobile computers, smartphones have become necessities (and sometimes problems) in people’s lives. This study was conducted to demonstrate the severity of smartphone addiction in two countries. Korea is a leading country in the mobile broadband market in terms of market penetration ratio (total # of smartphones sold ÷ country population) and the U.S. is the number one country in the global smartphone market. Comparing smartphone addiction levels of these two countries gives insight to smartphone addiction trends and characteristics, for they are the most affected by smartphone addiction. This paper investigates usage patterns as determinants for smartphone addiction.
