Preliminary Readings With Annotations:

Zheng, S., Apthorpe, N., Chetty, M., & Feamster, N. (2018, November 1). User perceptions of smart home iot privacy. Proceedings of the ACM on Human-Computer Interaction. https://dl.acm.org/doi/10.1145/3274469 

This paper provides a comprehensive study of user perceptions regarding privacy in smart home environments. The authors conducted in-depth interviews to understand how users conceptualize and manage privacy risks associated with IoT devices. This work is crucial for my research as it directly addresses the privacy aspect of smart home technologies, which is a key concern for many users. It supports my research questions about privacy perceptions and their impact on user trust and interaction. The study’s findings on users’ mental models of smart home data collection and transmission can inform the design of privacy-enhancing interfaces. However, it also challenges my approach by highlighting the complexity of privacy concerns, which vary significantly among users and device types. This suggests that a one-size-fits-all approach to privacy in UX design may not be sufficient, prompting me to consider more adaptive or customizable privacy interfaces in my research.

This study investigates user expectations of smart home technologies, providing valuable insights into the perceived benefits and concerns across different user groups. The authors highlight the gap between user expectations and current smart home offerings. This work is crucial for my research as it establishes a baseline understanding of user perceptions, which can inform the design of more user-centric interfaces. It supports my research questions by emphasizing the importance of considering diverse user needs. However, it also challenges my approach by suggesting that user expectations may sometimes be unrealistic, prompting me to consider how to balance innovation with practical limitations in interface design.
