Task 1

• Draw a picture of a person using a computer
• You have 60 seconds

2
Task 2

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

3
Drawing a line

• This is what it typically looks like.

4
Drawing a line

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

5
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

Single Display Groupware
10
Single Display Groupware

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

11
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
12
Why now?

• Screen size increasing
• large LED screens, HDTV, projectors, tabletop
  displays, Smart boards
• Public vs. personal location
• living rooms, family rooms, public walls

The Problem

• GUI toolkits ignore multiple inputs, multiple
  users

20
Solutions

• Research technologies that provide
• multiple mice and keyboards
• multiple cursors
• multi-touch surfaces
• vertical displays
• tabletop displays
• About 15 years of work in this area

SDG widgets Multi-user widgets
23
SDG widgetsLocal Tools

• Instead of tool palettes
• scatter tools atop the work surface
• pick it up and use it
• put it down when down
