Through the theoretical lens of perceived characteristics of innovations (PCI) framework, the main purpose of this research was to examine whether perceived characteristics of interactive technologies—interactivity, hypertextuality, modality, connectivity, and virtuality were related to user involvement, which in turn were related to the intention to continue using interactive mixed reality platforms. An e-survey questionnaire was administered to active mixed reality technology users (n = 268) across the US. Findings revealed that interactivity, modality, connectivity, and virtuality were positively related to user involvement, whereas, hypertextuality showed no significant impact. Furthermore, the hypothesized relationships between perceived characteristics of interactive technologies and user involvement and between user involvement and continuous usage intention were greater for mixed reality platform users with high digital literacy than for those with low levels.
