Using Personal Devices to Facilitate Multi-user Interaction with Large Display Walls

Large display walls and personal devices such as Smart-phones have complementary characteristics. While large dis-plays are well-suited to multi-user interaction (potentially with complex data), they are inherently public and generally cannot present an interface adapted to the individual user. However, effective multi-user interaction in many cases de-pends on the ability to tailor the interface, to interact without interfering with others, and to access and possibly share pri-vate data. The combination with personal devices facilitates exactly this. Multi-device interaction concepts enable data transfer and include moving parts of UIs to the personal de-vice. In addition, hand-held devices can be used to present personal views to the user. Our work will focus on using per-sonal devices for true multi-user interaction with interactive display walls. It will cover appropriate interaction techniques as well as the technical foundation and will be validated with corresponding application cases.
