Abstract
This study analyses how consumers choose to accept a radical or gradual innovation or stick with a ubiquitous computing device. Self-congruity theory, user engagement, innovativeness, and fun are examined. This research presents its findings. UCD users in Karachi who were educated urban inhabitants aged 18–35 were asked survey questions for the research. Convenience or self-selection selected these persons. AMOS 23 was used to code questionnaire results. Focused attention, interaction attractiveness, and perceived usability are the most important UCD user engagement factors. The first two boost playfulness and self-concept. Innovative customers adopt new gadgets, whereas non-innovative customers stick to what they know. Gender moderation shows that engagement, fun, and self-congruity promote innovation uptake. This study contributes to theory by examining gender inclusiveness, user engagement, and incumbent loyalty in innovation uptake.
