Off-Screen Annotations

• (full paper at CHI 2007)• Enable remote understanding of pace

and position of off-screen movement– Especially off-screen to on-screen transitions

• Requires two components:– Real-time tracking of local off-screen

position– Visualising at remote site(s) appropriately

Studies of MiMeG system in use

• (full paper at ECSCW 2007)• Some groups have agreed to be studied

in using the software in greater depth• describes the mechanisms researchers

use to manage distributed analysis– Local/remote activities– Gestures and imitation

• Significant evidence that managing local work is useful for distributed collaboration

Next Steps

• Do we aim to preserve/amplify existing practice? (which we have ethnographic evidence works for users) or do we aim to alter practice (based on experimental studies that say collaborative responses are easier to predict)

• What do we really want our software to do here – to support or to alter existing practice?

• Can we generate new domains of practice in real-time distributed research – is this a better commercial space than traditional workplaces?

Next Steps• Studies of distributed research practice in

CSCW are few and lack detail• Buxton’s (1992) Telepresence challenge

remains– integrating task-focused activities with object-

focused activities is still tough

• Real time groupware needs to move into the real world more, and perhaps researchers offer an improved testbed than traditional workplaces for real-time distributed tools
