### Qualitative Results  
In addition to the quantitative analysis, qualitative feedback from participants offers deeper insights into their experiences with the TAI and the NAI. This feedback was instrumental in understanding users' subjective perceptions and personal narratives concerning their engagement with the AR interfaces.  
Participants' responses to the TAI were mixed, with several highlighting its familiarity and ease of use, given the widespread prevalence of touch interfaces in daily technology interactions. However, a common theme among the feedback was a desire for more immersive and interactive experiences. Participants often described the TAI as functional but somewhat detached, lacking the depth of engagement they anticipated from AR technology. Some noted that while the TAI was straightforward, it did not significantly enhance their experience beyond traditional screen-based interactions.  
Feedback for the NAI was positive, with participants frequently commenting on the intuitiveness and immersive quality of the interaction. The ability to manipulate virtual objects directly through gestures was cited as a significant factor in the enhanced engagement and satisfaction with the AR experience. Participants described the NAI as \"innovative\" and \"engaging\", emphasizing how natural movements contributed to a more seamless integration of digital content into the physical world. The sense of presence and spatial awareness afforded by the NAI was highlighted as particularly impactful, with many expressing a preference for this interaction style for future AR applications.  
The qualitative insights reveal a distinct preference for the NAI over the TAI. Participants valued the NAI's capacity to provide a more engaging and life-like experience, transcending traditional interaction paradigms. It was not just about replacing the sense of touch with audio; it was about augmenting the sensory experience and enriching the user's mental model of the AR environment. Particularly for applications that require spatial manipulation or benefit greatly from an enhanced sense of presence, the NAI was seen as a key to unlocking a more profound and meaningful interaction.  
Furthermore, participants offered constructive feedback for improving both interfaces. For the NAI, suggestions included incorporating more granular and diverse audio feedback to simulate a wider array of textures and interactions, potentially enriching the realism of the AR experience. For the TAI, enhancements in touch sensitivity and response consistency were proposed to streamline the interface's functionality and responsiveness.  
The qualitative feedback, when considered alongside the quantitative findings, paints a comprehensive picture of user preferences and experiences with AR interfaces. It underscores the importance not only of usability, but also the emotional and experiential aspects of interaction in the design of AR systems. By continually refining and innovating natural user interfaces, developers can create AR experiences that are not just functionally robust but also deeply engaging, memorable, and accessible to all users, including those with visual impairments. This study illuminates the path forward, advocating for a user-centric approach that places immersive experience and inclusivity at the heart of AR technology development.
