University of LancasterVisit to Computing
Department
  • Equator Project
  • Digital Care Experience
  • Care settings
  • Difficult and sensitive
  • Previous work
  • Ethnographic observational techniques
  • Cultural probes (Gaver et al., 2001)
  • This work focus
  • Staff at one location
  • Using a framework to understand to propose
    technology

8
A Housing TrustResearch questions
  • How useful are trajectories for understanding
    sensitive care settings?
  • What methods are most effective for understanding
    these settings with a view to design?
  • How does the subtleties of the setting affect
    technology choice?

STEP 1 Understanding staff lifeA taste of the
log data
  • mu 2 bol 0 cheeky
  • please ring botcherby office sap. Thanksssss
  • Do you realise that all these messages are
    looked at Lancaster university?
  • im at the house talking to
  • did you hear the one about the 2 hungry sharks?
  • has been on the phone quiite stressed asking
    for her medicationsays she has been ringing
    since 6.15.

13
STEP 1 Understanding staff lifeImportant
concepts
  • Trajectory
  • a course of actionembraces the interaction of
    multiple actors and contingencies that may be
    unanticipated and not entirely manageable
  • Strauss, 1993 53
  • Locale
  • the use of space to provide the settings of
    interaction, the settings of interaction in turn
    being essential to specifying its contextuality
  • Giddens, 1984118
  • A locale is constituted by the relationship
    between a particular social world and its
    interactional needs, and the site and means
    used to meet those needs, i.e., the space
    together with the resources available there.
  • Fitzpatrick, 199891

14
STEP 2 Understanding staff lifeSome interview
themes (staff)
  • Phases and schedules in the day
  • Immediacy of staff life
  • The effectiveness of existing routines
  • Importance of information transfer
  • e.g. handover, telephone messages
  • The site as a residential home
  • The ongoing, evolving care plan
  • The importance of shared care knowledge
  • The need to focus on the positive

15
STEP 3 Understanding staff lifeScenario 1 -
Changing shift
  • You are coming to the end of your shift and are
    talking through the days events with the next
    member of staff. A resident enters and wants to
    talk to you desperately. You ask politely for the
    resident to wait until you have finished talking
    to the staff member. The resident seems anxious.
    You stop the changeover and walk to the pool room
    to talk to the resident.

16
STEP 3 Understanding staff lifeScenario 2
Happy memories
  • You are trying to organise a day trip to
    Blackpool for a few weeks time. During your
    morning routine when you check on residents you
    notice that one seems really excited about the
    trip as she has been to Blackpool before and has
    some good memories of the place. This is the
    first time youve seen her as excited about
    something in a long time.

  • PostIt notes
  • Pens glue

18
STEP 5 Design WorkshopVerification,
presentation piloting
  • Verification of scenarios
  • Presentation of technology
  • Phone cameras
  • Infrared
  • MMS
  • Public displays
  • Piloting of probe materials in groups

STEP 5 Design WorkshopPresentation of technology
Taking piccies
Sending piccies

STEP 6 Collaborative DesignInitial designs
  • Digital complaints book
  • 1710 1820
  • Photo display e.g. for sharing photos
  • 2120 2310

21
Issues with understandingHow do we know we are
right?
  • Ethically right
  • No framework for this
  • Its really hard to be a good guy
  • Trustworthiness
  • Prolonged engagement
  • Peer debriefing
  • Member checking
  • Audit trails
  • Multiple views on data

22
Issues with designTrue envisagement
  • Technology on my mind
  • Technology driven design
  • Feasible participatory design
  • Designing when constraints important
  • Envisagement from nothing
  • The non-designer asked to design
  • Technology on the edge
  • Solutions for care settings
  • Peripheral design
  • Picture of probe pack

23
Issues with techniquesProbing the probes
  • Cultural probes (Gaver et al., 2001)
  • About design
  • Inspirational (about ideas)
  • Focal (provide focus for design)
  • Interpretative (involve the designer being wacky)
  • Cultural probes (Crabtree et al., 2003)
  • About understanding
  • Focal (provide focus for understanding)
  • Analytic (of activity)
  • Longitudinal (over a period of time)

24
Issues with techniquesProbing the probes
  • Technology probes (Cheverst et al., 2004)
  • About understanding
  • Embodied (have physical form)
  • Prototypical (form resembles a design)
  • Situational (in a setting)
  • Peripheral (on the edge of activity)
  • Analytic (of activity)

25
The leap into designProbing the probes
  • Participatory design probes? (this study)
  • Shared
  • Embodied actual
  • Longitudinal
  • Situational
  • Analytic
  • Prototypical
  • Constrained (design constrained by understanding)

26
The road ahead Using the data
  • Finish data collection
  • Post probe cued recallor exit interview
  • Extrapolate design patterns
  • Getting at design
  • Collaborative design with engaged experts
  • At what stage of the development cycle do we use
    different kinds of probes?

27
Reflection Comment on usefulness of Locales
  • Good as a frame for understanding
  • Less to say about techniques
  • Limited articulation of quality criteria
  • Techniques?
  • Participative inquiry
  • Participative design
  • Meta-methodology
  • Guba Lincoln (1989) quite useful
