CONTRIBUTION TO QUALITY OF LIFE: CROSS-NATIONAL VALIDATION OF NEW METRICS FOR MOBILE DATA SERVICE TECHNOLOGY IN KOREA AND JAPAN

Every technology should be geared to improve the quality of users' lives. The important pre-requisite is to measure the contribution of the technology to quality of life reliably and validly. This study provides a theoretical and empirical basis for the development of better measures for the contribution of a mobile data service technology to the quality of users' lives. The reliability and validity were verified through online surveys in Korea and Japan. The survey results indicated that critical mobile data services could be identified using the measures. Moreover, the critical services were found to be different between Korea and Japan.
