Balancing Usability and Compliance in AI Smart Devices: A Privacy-by-Design Audit of Google Home, Alexa, and Siri

A research study analyzed privacy and usability trade-offs in AI smart devices (Google Home, Alexa, Siri) used by youth, finding that Google Home scored highest for usability while Siri led in regulatory compliance. The study revealed that while youth feel capable of managing their data, technical complexity and unclear policies limit their privacy control.

• →Google Home achieved the highest usability scores among the three AI smart devices tested.
• →Siri demonstrated the strongest regulatory compliance with privacy standards.
• →Alexa showed clearer task navigation but had weaker transparency in data retention practices.
• →Youth users have limited privacy self-efficacy due to complex technical settings and unclear data policies.
• →The study recommends enhancing transparency and improving privacy guidance during device onboarding.
