Interruption in f2f conversation • “Any deviation from a smooth speaker switch” • Ulijn & Li • Unmarked – gives impression of a normal turn switch. • e.g. during hesitation in 2nd half of utterance • Marked – Depicted as unexpected by the speaker • e.g. during planning hesitation, or while speaking • Marked interruptions are more frequent • Study of Chinese, Finnish, Dutch – Ulijn & Li
Interruption as Face Threat • True interruption (violation of norms) is a face threat. • Threat to positive face (desire for inclusion) • Threat to negative face (desire for autonomy) • Depending on nature of relationship, some amount of mitigation is called for • Positive politeness: I’m really enjoying your story, but.. • Negative politeness: I’m very sorry, but…
Interruption in f2f conversation • Significant cultural variation in “involvement” style • Turn overlap / Inter-turn delay • Significant variation based on relationship • Power & Distance • Significant variation based on personality
Interruption in f2f conversation • Interruptions are not always bad • In a study of British and Italian management meetings, the majority of interruptions were facilitative (supporting, reinforcing, etc.). [Bargiela-Chiappini & Harris] • Power • Conflicting findings on relationship with frequency of interruptions. • One study: high power interrupt and are interrupted more (and have more floor time); low power individuals rarely interrupt and are rarely interrupted. [ibid]
Back to Clippit • Two levels of interrupt: • Shortcut tip – displays light bulb • Important, timely information — taps at the screen and gestures. • In both cases, character appears if not already displayed. • Both “wanting turn” signals, may be interpreted as interruptions.
Suggestions for Clippit2 • Only interrupt at “transition relevant points” • When user has paused, or is otherwise in-between tasks. • Use gaze to help determine when user is giving the turn. • Be sensitive to culture, personality, “relationship”, even task context • e.g., a user on deadline probably doesn’t want tips • Be clear about how the relationship works • Express appropriate politeness
