論文アブストラクト：Users have access to a growing ecosystem of devices (desktop, mobile and wearable) that can deliver notifications and help people to stay in contact. Smartwatches are gaining popularity, yet little is known about the user experience and their impact on our increasingly always online culture. We report on a qualitative study with existing users on their everyday use of smartwatches to understand both the added value and the challenges of being constantly connected at the wrist. Our findings show that users see a large benefit in receiving notifications on their wrist, especially in terms of helping manage expectations of availability. Moreover, we find that response rates after viewing a notification on a smartwatch change based on the other devices available: laptops prompt quicker replies than smartphones. Finally, there are still many costs associated with using smartwatches, thus we make a series of design recommendations to improve the user experience of smartwatches.
