Task 1 Draw a picture of a person using a computer You have 60 seconds

Task 2 Draw a picture of multiple people using a computer You have 60 seconds

Drawing a line This is what it typically looks like.

Drawing a line How should a line behave if 2 people were using it? Task 3. –Sketch out several design ideas

Drawing a line How should a line behave if 2 people were using it? Task 3. –Sketch out several design ideas –Now do it again after you: get a partner manipulate a rubber band, string to help generate ideas

How people work together Contrast restrictions imposed by –screen / mouse / keyboard vs. –paper / pencil Video (Xerox PARC) [.wmv][.wmv]

Single Display Groupware

Co-located people work simultaneously on –a table, a wall display, or a monitor through –multiple mice, keyboards, multi-touch surfaces

Characteristics of SDG applications Support to face-to-face interaction Shared and coupled view Shared user interface Shared feedback Multiple cursors Different input devices No privileged devices Slide adapted from A. Zanella presentation on Single Display Groupware

Why now? Screen size increasing –large LED screens, HDTV, projectors, tabletop displays, Smart boards… Public vs. personal location – living rooms, family rooms, public walls
