A MODEL FOR APPROPRATION: REQUIREMENTS

• Account for the richness of appropriation process

• Variety of related processes• Situated into a social / cultural / technological

context

• Explain specifics of digital technology appropriation

• Gap between user and digital representations• Structures and operations to bridge this gap

CASE STUDY: PRESENTATION

• Context• 7 Cinema Researchers• New Video Annotation Tool• Collaborative Movie Analysis Practice

• Research Question• To what extent does DIAM help to describe

appropriation?

• Material• Pre & Post Interviews (14)• On field-observations• Interaction traces & Screenshots

The model helps to describe appropriation

• Explain user particularization of information structures

The model fails into taking into account

• Instrument based on multiple-tool• Collaborative dimension of appropriation

Potential of interaction traces

• Detect circulation and moment of instrumental instability

• Detect utilization schemes

CASE STUDY : CONCLUSION

30

• A dynamic model to describe evolutions of digital artifact over the appropriation process

• Extending Instrumental Theory• Taking into account specifics about appropriation of

digital artifacts

• First experimentation promising

• Key concepts to design and evaluate appropriability of artifacts

CONCLUSIONS

31

PERSPECTIVESFine-grained modelling of interaction level

Understand the role of mediation over users’ representation of data

Overstepping the « 1 Instrument = 1 Application » simplification

Towards appropriation-aware technology ?

• From interaction traces to appropriation traces• Better understanding of usage evolution over time• Assist user with instrumental development
