Motivation for Studies

• Studies of calendars part of a wider
  investigation of technology use in the home
  sponsored by the Equator IRC www.equator.ac.uk
• The calendar is one of the most successful
  coordination tools in the workplace
• Calendars are ubiquitous in the home an
  opportunity to explore ubiquitous computing
  concretely (beyond the lab)

3
The Domestic Challenge

• Problem
• The home and the workplace are different social
  organizational domains each with unique needs
• Existing approaches developed in the workplace
  are inappropriate
• Solution
• Explicate the interpretive work (Dourish et al.
  1993) of calendar work in the home i.e.
  embodied arrangements of interaction observably
  and reportably implicated in the use of calendars
  whereby household members make sense of calendars
  and coordinate their work together

4
Addressing the Challenge (1)

• Instance 1.
• The Calendar as an Accountable Social Object

5
Addressing the Challenge (2)

• Instance 2.
• Essential Accountable Work-Practices

6
Addressing the Challenge (3)

• Instance 3.
• Negotiation and Collaboration

7
Findings

• A Corpus of Accountable Work-Practices
• Situating calendars so that they are available to
  collaboration
• Complying with coordination protocols
• Making visibly distinct annotations
• Adding explicatory notations
• Accomplishing collaborative access

8
Implications for Design

• Merging the Physical with the Digital
• Anywhere, anytime
• Devising Negotiation Protocols
• Computer mediated interaction
• Supporting Collaborative Access
• Distributed collaboration
