Cross-device environments (XDEs) have been devel-oped to support a multitude of collaborative activities. Yet, little is known about how different cross-device in-teraction techniques impact group collaboration; in-cluding their impact on independent and joint work that often occur during group work. In this work, we explore the impact of two XDE data browsing tech-niques: TOUCH and TILT. Through a mixed-methods study of a collaborative sensemaking task, we show that TOUCH and TILT have distinct impacts on how groups accomplish, and shift between, independent and joint work. Finally, we reflect on these findings and how they can more generally inform the design of XDEs.NSER
