# VR Reading Revolution: Decoding User Intentions Through Task-Technology Fit and Emotional Resonance
## 2 Literature Review and Research Hypothesis  
### Usage Intention  
The concept of intention originally stems from the field of psychology, where it denotes an individual's subjective inclination triggered by external stimuli, which in turn motivates specific behavioral responses. [PERSON] [21] conceptualizes intention as a distinct cognitive activity separate from intrinsic attitudes, reflecting an individual's conscious planning and preparedness for a given behavior. In the Theory of Planned Behavior (TPB), [PERSON] [22] further posits that behavioral intention constitutes the immediate antecedent of action, with its strength being positively correlated with the likelihood of actual behavior. Within the domain of technology adoption, usage intention has emerged as a pivotal construct for evaluating whether users are willing to try, adopt, and continue utilizing a technological solution. This construct is extensively applied in the Technology Acceptance Model (TAM) and its extended frameworks, where it is typically defined as an individual's subjective predisposition and future-oriented willingness to accept and engage with a product, service, or system. Influencing factors of usage intention can be broadly categorized into internal (e.g., perceived usefulness and perceived ease of use) and external (e.g., social influence and environmental support) dimensions. The empirical findings by [PERSON] and [PERSON] [23] demonstrate that in the context of metaverse-based educational platforms, personalized learning, situational pedagogy, and social influence all exert significant positive effects on users' usage intention.  
In digital environments, usage intention not only predicts the initial acceptance of emerging technologies, but also closely relates to sustained user engagement. This is particularly evident in applications involving immersive technologies, where factors such as perceived experience, interactive convenience, and social participation form critical antecedents to the formation of usage intention. In the present research context, usage intention is examined specifically within the application environment of VR digital libraries. By leveraging immersive VR technologies, VR libraries construct three-dimensional knowledge service spaces that encompass core functionalities of traditional libraries--such as document retrieval, collection browsing, personalized recommendation, and interactive learning--while significantly expanding users' information acquisition and reading experiences through spatial navigation, multimodal interaction, and avatar-based social engagement. Compared to conventional web-based digital libraries, VR libraries emphasize spatial reading and immersive information retrieval, which more effectively enhance users' perceived value and motivational readiness for platform adoption. Accordingly, this study defines usage intention as the user's subjective psychological expectation and behavioral tendency to access, use, and continuously engage with digital library services in a virtual reality environment, driven by evaluations of both functional affordances and affective experiences of the platform.
