Problem – Grounding Borders

Problem – Signalling and Grounding Interpersonal privacy conflicts Vulnerability of being always on Undesired interruption Lack of understanding of each others representations False expectations and obligations Physical, emotional and cognitive effort Communicators lack of lightweight and effective mechanisms to signal and ground each others’ intentions to interact

Interpersonal privacy conflicts

Vulnerability of being always on

Undesired interruption

Lack of understanding of each others representations

False expectations and obligations

Physical, emotional and cognitive effort

Communicators lack of lightweight and effective mechanisms to signal and ground each others’ intentions to interact

Approach Security Legal Social

Approach Privacy as a BORDER REGULATION process (Altman, 1975) Privacy is dynamic and dialectic Opening and closing borders of interaction Privacy as a GROUNDING process (Clark, 1996) Establishing a shared understanding of each others’ representations for interaction

Privacy as a BORDER REGULATION process

(Altman, 1975)

Privacy is dynamic and dialectic

Opening and closing borders of interaction

Privacy as a GROUNDING process

(Clark, 1996)

Establishing a shared understanding of each others’ representations for interaction

Solution Privacy Grounding Model (PGM) Representing privacy borders Establishing a shared understanding

Privacy Grounding Model (PGM)

In practice … Identify the parties interacting 1 to 1; 1 to many; many to many communication Hierarchy / Collaboration Identify their borders of interaction 1 or 2 ways communication Asynchronous/synchronous Text/visual/audio Formal/casual Identify scenarios of coordination of borders : ‘ knocking’ other’s borders: sending an email Opening/closing your borders (after someone’s ‘knocking’): changing status to busy

Identify the parties interacting

1 to 1; 1 to many; many to many communication

Hierarchy / Collaboration

Identify their borders of interaction

1 or 2 ways communication

Asynchronous/synchronous

Text/visual/audio

Formal/casual

Identify scenarios of coordination of borders :

‘ knocking’ other’s borders: sending an email

Opening/closing your borders (after someone’s ‘knocking’): changing status to busy

In practice … Identify signalling mechanisms to communicate intentions of opening/closing/knocking borders Sending an email with a ! symbol Lightweight: brief, background, simultaneous, distinctive Interactive and Lightweight Identify grounding mechanisms to establish understanding of the intentions of signalled borders Clicking the ! to ground its importance (though no answer can be provide yet) Interactive

Identify signalling mechanisms to communicate intentions of opening/closing/knocking borders

Sending an email with a ! symbol

Lightweight: brief, background, simultaneous, distinctive

Identify grounding mechanisms to establish understanding of the intentions of signalled borders

Clicking the ! to ground its importance (though no answer can be provide yet)

Conclusions Grounding mechanisms support lightweight and effective collaborative practices to establish a shared understanding of each others’ representations of privacy borders Lightweight Interactivity Effective in developing a shared understanding Least collaborative effort Explicit and ambiguity

Grounding mechanisms support lightweight and effective collaborative practices to establish a shared understanding of each others’ representations of privacy borders

Lightweight

Interactivity

Effective in developing a shared understanding

Least collaborative effort

Explicit and ambiguity
