The widespread adoption of feature phones and smartphones has previously led researchers to test the assumption that users always have their phones ready at hand. We believe the current ubiquity of other smart devices has changed this. Using a mixed methods approach inspired by past work in this area, we reevaluate the physical proximity relationship between individuals and their smartphone, as well as the role of other smart devices in users’ lives. We find that, on average, participants have their phone within arm's reach 51% of the time, similar to the findings of the prior work. However, if smartphones are not within arm's reach, they are now much further away because of the use of wearables and other devices. We also show how social, personal, and external factors result in users relying on other devices for functions (e.g., information seeking, checking the weather, setting timers and alarms, and playing music) once performed by their smartphones.

分道扬镳：智能设备如何影响用户与智能手机的距离

此前，功能手机和智能手机的广泛采用促使研究人员测试了用户始终准备好手机的假设。我们相信，当前无处不在的其他智能设备已经改变了这一点。使用受该领域过去工作启发的混合方法，我们重新评估了个人与其智能手机之间的物理邻近关系，以及其他智能设备在用户生活中的作用。我们发现，平均而言，参与者有 51% 的时间将手机放在伸手可及的范围内，这与之前的研究结果相似。然而，如果智能手机不在触手可及的范围内，那么由于可穿戴设备和其他设备的使用，它们现在离得更远了。我们还展示了社交、个人和外部因素如何导致用户依赖其他设备来实现功能（例如，
