Mobile Kits and Laptop Trays: Managing Multiple Devices in Mobile Information Work

摘要

A study at a large IT company shows that mobile information workers frequently migrate work across devices (here: smartphones, desktop PCs, laptops). While having multiple devices provides new opportunities to work in the face of changing resource deprivations, the management of devices is often problematic. The most salient problems are posed by 1) the physical effort demanded by various management tasks, 2) anticipating what data or functionality will be needed, and 3) aligning these efforts with work, mobility, and social situations. Workers' strategies of coping with these problems center on two interwoven activities: the physical handling of devices and cross-device synchronization. These aim at balancing risk and effort in immediate and subsequent use. Workers also exhibit subtle ways to handle devices in situ, appropriating their physical and operational properties. The design implications are discussed.
