Exploratory study of cross-device search tasks
作者：
Highlights：
• Cross-device search tasks extracted from real situation experience by crowdsourcing.
• Characteristic of task types indicates the specificity of information needs in cross-device search.
• The task complexity depends heavily on user's cognition.
• Eight reasons for switching the device are concluded to understand the motivations for switching devices.
• Implications for designing cross-device search tasks are proposed based on the correlation among task attributes.
