Designing and Evaluating a Prototype for Data-Related Privacy Controls in a Smart Home

The privacy concerns of home Internet of Things (IoT) device users and experts have been widely studied, but the designs of privacy controls addressing those concerns are sparse. Literature shows a significant body of research uncovering design factors for privacy controls in smart home devices, but fewer studies have translated those design recommendations into design and evaluated the designs. To fill this gap, we designed a prototype user interface implementing the design recommendations of data-related privacy controls based on prior work and evaluated the prototype for user experience, usability, perceived information control, user satisfaction, and intention to use. The results of interviews (n = 10) critique the proposed design and the survey results (n = 105) show that the prototype design provides positive evaluation for perceived information control, user satisfaction and intention to use. Based on findings, we discuss design recommendations for further improvements. Thus, this paper contributes to the design of data-related privacy controls for user interfaces of home IoT devices and applications.
