# VR Reading Revolution: Decoding User Intentions Through Task-Technology Fit and Emotional Resonance
## 2 Literature Review and Research Hypothesis
### External Influences
In addition, when a majority of people in a social network recommend and use a certain technology at the same time, a \"herd effect\" is formed, and more users are motivated to follow through social pressure [29]. On the new platform of virtual reality digital libraries, the complexity of the technology interface and the limited experience of users make it easy to generate uncertainty. Peer recommendation not only provides empirical references, but also reduces users' risk perception regarding the platform through the emotional trust mechanism, and enhances their willingness to adopt. Therefore, combining the path logic of TPB and SCT, this paper proposes the following hypothesis:  
**H1b. **: _Peer recommendation has a positive effect on usage intention._  
In addition to social influences, users' perceived risks in evaluating new technologies are also important negative variables affecting their behavioral intentions. TAM and its extended model include perceived risks as one of the external inhibitors explaining users' hesitations and reservations when confronted with new platforms. Among them, privacy and security risk is particularly critical, and this usually refers to problems such as identity theft and property loss caused by the leakage, misuse or unauthorized access of personal information and behavioral data. In highly interactive virtual reality environments, users are often required to provide account information, behavioral records, and even facial and movement data to enable immersive experiences and content recommendations. Such high-intensity data exposure inevitably triggers privacy anxiety. The study points out that data leakage, system vulnerability, and permission issues in data sharing are the core factors leading to decreases in users' sense of security [30; 31; 32]. [PERSON] [33] found that when users perceive privacy risks in a platform, their willingness to participate and adopt significantly decreases. From the perspective of Innovation Diffusion Theory (IDT), privacy risks also weaken users' perceptions of the system's comparative advantage and compatibility, while increasing the perception of complexity, which further depresses the motivation to use. Therefore, privacy and security risk is not only a negative belief variable in technology adoption, but also a mode of cognitive resistance. Based on this, this paper proposes the following hypotheses:  
**H1c. **: _Privacy and security risk has a negative effect on usage intention._  
With the widespread proliferation of concepts such as VR, AR, and \"meta-universe\", immersion has re-emerged as a central variable of academic and practical interest. As early as the 1990s, [PERSON] [34] pointed out that immersion is a capability determined by the properties of a system, which can trigger the user's sense of presence by means of immersive displays, interaction mechanisms, and sensory overlays. Since then, a large number of studies have explored the components and behavioral impacts of immersive experiences from technical, psychological and perceptual dimensions [35]. Immersion is not only an enveloping experience of sensory input, but it also reflects the psychological state of \"being there\" that users feel in virtual environments. [PERSON] et al. [36] suggested that immersion can be quantified by indicators such as sensory range and attention span, and [PERSON] [37] pointed out that a high level of immersion may also cause changes in body perception, emphasizing the impact of immersion technology on the cognitive system. [PERSON] pointed out that a high level of immersion may also cause changes in body perception, emphasizing the impact of immersion technology on the cognitive system. In VR digital libraries, users need to complete information retrieval, reading and interactive learning through immersive technology, and the depth of their immersion experience is not only affected by the system performance, but also directly related to the degree of their psychological participation and cognitive input.
