Voice-controlled intelligent personal assistants (IPAs) have seen tremendous growth in recent years on smartphones and as standalone devices in people’s homes. While research has examined the potential benefits and drawbacks of these devices for IPA users, few studies have empirically evaluated the role of privacy and trust in individual decision to adopt IPAs. In this study, we present findings from a survey of IPA users and non-users (N=1160) to understand (1) the motivations and barriers to adopting IPAs and (2) how concerns about data privacy and trust in company compliance with social contract related to IPA data affect acceptance and use of IPAs. We discuss our findings in light of social contract theory and frameworks of technology acceptance.
Eliciting Privacy Concerns for Smart Home Devices from a User Centered Perspective
George Mason University, United States of America
Smart homes are equipped with an ecosystem of devices that support humans in their everyday activities, ranging from entertainment, lighting and security systems. Although smart devices provide home automation features that are convenient, comfortable, and easy to control, they also pose critical privacy risks for users, especially considering their continuous ability to sense users' information and connect to web services. To elicit privacy concerns from a user-centric perspective, the authors performed a thorough analysis of 128 online reviews of consumers of smart home hubs – including Amazon Echo, Google Home, Wink and Insteon. The reviews, filtered from a set of 66656 selected reviews, expressed users’ concerns about privacy. The reviews were coded and classified according to four information security principles and temporal dimensions ranging from data collection to information sharing. A discussion on how to improve the design of smart home devices with privacy-enhanced solutions is provided.
A Study of Usage and Usability of Intelligent Personal Assistants in Denmark
Aalborg University Copenhagen, Denmark
Intelligent personal assistants (IPA), such as Siri, Google Assistant, Alexa, and Cortana, are becoming an increasingly popular way of interacting with our smartphones and typically the only way of interacting with smart speakers. As a result, there has been a wealth of research on all aspects of IPAs in recent years, such as studies of usage of and user satisfaction with IPAs. However, the overwhelming majority of these studies have focused on English as the interaction language.
In this paper, we investigate the usage and perceived usability of IPAs in Denmark. We conduct a questionnaire with 357 Danish-speaking respondents that sheds light on how IPAs are used in Denmark. We find they are only used regularly by 19.9% of respondents and that most people do not find IPAs to be reliable. We also conduct a usability study of Siri and find that Siri suffers from several issues when used in Danish: poor voice recognition, unnatural dialogue responses, and an inability to support mixed-language speech recognition. Our findings shed light on both the current state of usage and adoption of IPAs in Denmark as well as the usability of its most popular IPA in a foreign-language setting.
