Collaborating Face-to-face & with NetMeeting & Grove Comp 290-063 (Fall 04) Goal of Assignment • Read abstracts of CSCW’00 & CSCW’02 papers. • Classify them collaboratively based on – – – – Application area Tasks Issues Disciplines • Use face to face for one proceedings and NetMeeting for another. • Note times for classifying each paper. • Write document using Groove comparing face to face and NetMeeting experiences. • Write document using chosen collaboration technology comparing Groove with email • Assumed document will be written synchronously Unconstrained Factors • How many computers used in face to face. • Whether distributed users use IM or phone for communication. • What apps were shared in distributed setting • How large the groups were. • How evenly distributed the partitioning. • How many sessions used for each task. • Which Groove tools used. Group 1 • William Luebke • Priyank Porwal Set Up • Face to face set up – # computers: 1 – Division of labor • One person managing browser windows and Excel table • 2nd user just contributed. • NetMeeting Set Up – Excel and browser shared through NetMeeting – Shared windows occupied complete screen – NM chat used. – Division of labor • One person communicated Pros and Cons • No technical difficulties in starting. • Eye contact • Audio communication made it easy to discuss. • Felt it was faster. – Need to calculate • Not shuttled from room to room. • Could play music in background. • Concurrency – Used? Group 2 • John Calandrino • Ankur Aigiwal Set Up • Face to face set up – # computers: 1 – Division of labor • One person in control • 2nd user just contributed. • NetMeeting Set Up – All relevant windows shared – Audio chat used – Division of labor • One person mainly in control • Other occasionally edited table Pros and Cons • No technical difficulties in starting. • Eye contact • Audio communication made it easy to discuss. • No delays in communication – NetMeeting significant delay when non hosting user input. – NetMeeting – switching of windows by hosting user not seen by remote user. • No awkwardness of control exchange • F2F preferred overall. • Did not gesture in face to face so lack of gestures not an issue. • Higher cost of communication made classification time longer. • Lack of sufficient physical space not a problem – no need to huddle in front of computer. Group 3 • Karl Gyllstrom • Henry McCuen • Sasa Junuzovic Set Up • Face to face set up – # computers: 2 – Division of labor • One person managing browser windows – Class PPT presentation, Class notes, abstracts • One person filled classification Excel table • 3rd user just contributed. • NetMeeting Set Up – Excel shared through NetMeeting – Class PPT presentation and abstracts not shared to allow independent views – NM chat used. – Division of labor • Not specified. Pros and Cons • No technical difficulties in starting. • Pointing and communication using body gestures. • Faster communication using audio. • Group would focus and relax synchronously based on cues. • Easier to challenge a person’s ideas. In NM more irrelevant items were added • No occlusion of shared windows by pvt windows. • Browser windows had to be manually synchronized • Average time per abstract less because less challenges (and chit chat?) despite using text communication • Multiple users could control shared state – text contents, window position. – Typed messages in cells. • Could have private email, browser, music. • Chat history referred to later. • Asynchronously replied later. • Succinct suggestions – Concurrency dbms – I think that because we have concurrency in the tasks column we should have dbms in the right column Group 4 • • • • Brett Clippingdale Lisa Fowler Kris Jordan Daniel Wiegand Set Up • Face to face set up – Session 1 • Two projectors • Abstracts table in separate projectors – Session 2 • Three computers for abstract, class notes, and classification document – Division of labor? • One person per computer? • NetMeeting Set Up – Session 1 • Non shared window recording classification • Abstract shared – Session 2 • Classification shared – IM used – Division of labor • One person mainly in control of shared window Pros and Cons • More discussion. • Easier communication – Lack of latency – Gestures, body language • Audio communication made it easy to discuss. • No delays in communication – NetMeeting significant delay when non hosting user input. – NetMeeting – switching of windows by hosting user not seen by remote user. • Person in charge of control did not dominate and others did not become passive. • Clear when someone absent or distracted. • In NetMeeting technical difficulties and establishing awareness took 30 minutes • Less distraction. • Brevity • Phone call or interruption of one person stopped everyone (pro or con?) • Did not gesture in face to face so lack of gestures not an issue. • Higher cost of communication made classification time longer. • Lack of sufficient physical space not a problem – no need to huddle in front of computer.

Group 2 • John Calandrino • Ankur Aigiwal Groove vs. Email • Groove tools – Word co-edit • Process • Pros – Could complete edits before feedback given • Unnecessary comments not given – Mail communication more heavyweight than mouse-click based communication – Initial draft written by • Communications fewer. one person during co– No need to merge document. editing. – Good computing and communication infrastructure – Other person took over, needed. underlining edits • Cons – Initial person then took – Requesting and relinquishing control took too much time. over, also underlining – Edits not seen until document edits. saved. – Prefer email with given computing and comm power. Group 3 • Karl Gyllstrom • Henry McCuen • Sasa Junuzovic Groove vs. Email • Groove tools – Workspace Chat – Real-time Editor • Process – Unspecified – assume concurrent editing – Each user assigned unique font color • Pros – Instant feedback and prevention of conflicts – Undo allowed easy transition to previous state – Shared version: No need to pass documents around – Tied to PCs. • Cons – Communication not time stamped. – Steep learning curve – Highlighting by one user and editing by other sometimes lead to lost work. – Multiple edits caused unintended window scrolling Group 4 • • • • Brett Clippingdale Lisa Fowler Kris Jordan Daniel Wiegand Groove vs. Email • Groove tools – Word co-edit • Process – Initial draft put in document review tool and message put in discussion board. – Asynchronously commented and edited using user-specific font color. – Word co-edit used to finalize changes. • Pros – Persistent chat useful. – No overhead of sending, reading, organizing mails. – Notification of file changes. – Notification of online status. • Cons – Edits had to be explicitly pushed. – Lag caused inconsistent delays. – Chat did not support consistent order. Conclusions: Groove vs. email • Asynchronous communication – Groove lighter-weight • No need to write, read, organize mail. – Provides awareness and presence information. – Requires more computing power. • Synchronous collaboration – Requires more communication bandwidth – Allows more communication – Word co-edit • Pushing of changes and delay major problem. • Avoiding unnecessary comments minor advantage – Special text editor • Implicit sharing big win. • Tracking revisions or author of change would have been useful.
