Аннотация:Seniors’ use of mobile devices for tourism-related purposes is an emerging social trend, but there is little theoretically based research on the topic. This study examines seniors’ usage of mobile devices for tourism-related purposes, applying the extended model of goal-directed behavior. Usefulness and enjoyment are shown to have significant effects on seniors’ use of mobile devices for tourism purposes and prior knowledge of information technology has a significant impact on seniors’ desire and behavioral intention to use mobile devices for tourism-related purposes. This study offers theoretical and practical contributions to tourism academics and practitioners.
