1 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University The “Welcome, Matt” Communicating Interruptability via an Observable Message Board

2 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University The Problem  Lack of information passing between office inhabitants and potential visitors, esp. when door closed Inability to understand state of office from hallway Inability to understand state of hallway from office  Door not best indicator of interruptability Office inhabitants may want to close door, yet remain interruptable (e.g., for silence)

3 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Scenario I  Scott Hudson is grading homework and wants it quiet, so he closes the door  Judy Teeay comes by with more ungraded assignments, sees door is closed, and leaves  Scott opens door, realizing he may miss Judy. Hallway noise a nuisance. Judy never shows

4 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Scenario II  Sara Kiesler is on her way to an important faculty meeting  She knows Scott Hudson is cranking code and may not be able to come  Sara swings by Scott’s office; Door is closed  Meeting is crucial, so Sara knocks loudly  Scott loses brilliant solution forever

6 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University The “Welcome, Matt” (W.M.)  Facilitates bi-directional flow of information Uses situational awareness to give information to those outside of state inside Uses situational awareness to deem when messages from outside are presented inside  Information displayed outside subject to configuration & override by office inhabitant  Office inhabitant can view messages from visitors on computer

7 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Example: Inside to Outside

8 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Example: Outside to Inside

9 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Example con’t…

10 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Technology Requirements  W.M. hardware  Sensing number of room inhabitants  Sensing general locations of inhabitants At computer, at desk, on couch, on phone  Bonus: Identifying room inhabitants

11 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Scenario I (Revised)  Scott Hudson is grading homework and wants it quiet, so he closes the door  Judy Teeay comes by with more ungraded assignments, sees W.M. displaying “Scott Hudson is at his desk.”  Judy knocks; Scott is grateful for more assignments to grade. Judy goes out for pizza and beer

12 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Scenario II (Revised)  Sara Kiesler is on her way to an important faculty meeting  She knows Scott Hudson is cranking code and may not be able to come  Sara swings by Scott’s office; Door is closed  Sara sees on W.M. that Scott is at his computer He’s coding 20 w.p.m.  Sara leaves message Delivered when typing stops for 2 minutes

13 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Wizard of Oz for  Determine how people respond to various messages on W.M. outside office  Identify what information on W.M. is useful  Identify what messages might be left on W.M.  Explore design of W.M. and capabilities

14 J. O. Wobbrock ~ September 21, 2001Human Computer Interaction Institute ~ Carnegie Mellon University Thanks! The end
