“…Researchers have also delved into specific multi-device configurations such as dual-screen or multi-screen (e.g., [32,39,50]), tablet formations (e.g., [13,47]), companion devices such as mobile phones (e.g., [2,12,21,28,45]), or large screen displays (e.g., [4,16,51,63,66]). Prior work has also explored categories of application design techniques, including migratory interfaces [5,6,8] and migratable applications [26,27,64], which are asynchronous usage patterns related to the "migrate" pattern discussed by [11].…”
