Determinants of users' intention to adopt wireless technology: An empirical study by integrating TTF with TAM

This paper reported the results of a survey study and provided evidences of empirically testing a model that integrates both technology acceptance model (TAM) and task-technology fit (TTF) model in understanding the determinants of users' intention to use wireless technology in organizations Questionnaires were distributed to organizations that bring mobile commerce into practice through the wireless hand-held devices The results indicated that both technology acceptance model and task-technology fit model are robust models by themselves First, both perceived usefulness and ease of use significantly influence users' behavior intention to utilize wireless technology Perceived case of use has significant effect on perceived usefulness. Second, characteristics of technology and task significantly predict the fit between these two constructs. Significant effect of characteristics of technology on perceived ease of use and usefulness were observed Finally, significant relationships between TAM and TIT model were also observed Task-technology fit is a significant direct predictor of technology adoption intention Overall, users' intention to adopt wireless technology in organizations was determined directly by fit between characteristics of task and technology as well as users' perceived ease of use and usefulness (C) 2010 Elsevier Ltd All rights reserved
