3. 25 June 20163 Etiquette(s) of Adaptive Automation Etiquette rules are generally NOT created from scratch  based on observed good practice  extended into novel domains  made explicit for those who don’t get it naturally Etiquette rules for AA should be the same  observe good human/human practice  extend and generalize to AA Etiquette isn’t the same for all situations  Work situations are different than social ones Etiquette violations can be powerful Dear Miss Manners, Are there any rules of etiquette yet governing use of voicemail systems?

7. 25 June 20167 My Proposed Etiquette List for Associates 1. Make many, many correct conversational moves for every error. 2. Make it very, very easy to correct your errors. 3. Know when you are wrong--and then get out of the way. 4. Don’t make the same mistake twice 5. Don’t show off—Just because you can do something, doesn’t mean you should. 6. Be able to talk explicitly about what you’re doing and why— 7. Be able to take instruction; not only will this help you adapt to the user’s expectations, it may actually make you look smarter. 8. Make use of multiple modalities and information channels redundantly 9. Don’t assume every user is the same—be sensitive and adapt to individual, cultural, social, contextual differences 10. Be aware of what the user knows—especially if you recently conveyed it (i.e., don’t repeat yourself). 11. Try not to interrupt. Err on the side of caution. 12. Be cute only to the extent that it furthers your interaction goals.

8. 25 June 20168 Horvitz’s ‘Courteous Computing’ (CHI’99) 1. Provide significant, genuine, value-added automation 2. Consider uncertainty about user goals 3. Consider the status of a user’s attention in timing services 4. Infer ideal action in light of costs, benefits and uncertainties 5. Employ dialog to resolve key uncertainties 6. Allow efficient direct invocation and termination 7. Minimize cost of poor guesses about action and timing 8. Scope precision to match goal uncertainty and variations 9. Provide mechanisms for efficient agent-user collaboration to refine results 10. Employ socially appropriate behaviors for agent-user interaction 11. Maintain working memory of recent interactions 12. Continue to learn by observing. “…the sensitivity of an intuitive, courteous butler…”

9. 25 June 20169 Etiquette is … 1 “… the defined roles and acceptable behaviors or interaction moves of each participant in a common ‘social’ setting … Etiquette rules create an informal contract between participants in a social interaction allowing expectations [and interpretations] to be formed and used about the behavior of others.” --(from the Symposium description)

10. 25 June 201610 Etiquette is … 2 “…(1) the body of prescribed social usages. (2) Any special code of behavior … : ‘In the code of military etiquette, silence and fixity are forms of deference’ (Ambrose Bierce). … Synonyms: propriety, decorum, protocol.” --American Heritage Dictionary Etiquette as “the Social Niceties” versus etiquette as domain conventions

11. 25 June 201611 Social Niceties vs. Work Conventions Both prescribe some behaviors and proscribe others for participants Both assign meaning to behaviors  Facilitates efficiency and clarity of intent within the domain  Brown and Levinson on Politeness as diffusion of hostile intent Etiquette is the set of prescriptions and proscriptions  “Social niceties” are generalized etiquette  “Military etiquette” and ATC protocols are specialized etiquettes Work domains frequently dispense with the polite forms of generalized etiquette in favor of their specialized etiquettes Range of Possible Behaviors Prescribed Behaviors for Domain X Proscribed Behaviors for Domain X Etiquette for Domain X Specialized Generalized

12. 25 June 201612 Dimensions or Attributes of Etiquette 1 Different Etiquettes for Different Interactions Etiquette Evolves  Within individuals and in response to cultural and technological changes  learning of interfaces?  Initial etiquette tends toward the more formal precisely because it is most general X ~X Strongly Proscribed Behaviors for Context = {X  Y  Z} ~Y~Z Z Y Most likely (most conservative) source of acceptable Behaviors in Context = {X  Y  Z} X = Church location Y= Friend Z= Football

13. 25 June 201613 Dimensions or Attributes 2 Etiquette is mostly implicit  Will be difficult to encode Etiquette is only expected of ‘intelligent’ agents  But the barriers to imputed intelligence are low  Exhibiting etiquette implies intelligence Etiquette generally implies roles  Generalized: e.g., petitioner/responder  Specialized: e.g., pilot/copilot  Power relationships are frequently encoded as roles  Not all prescribed behaviors are appropriate for all roles  Behaviors that violate role boundaries will strongly marked and potentially confusing Etiquette for Domain X X.A X.B ~X.B Prescribed behaviors for Role A and B in Domain X Unacceptable behaviors for Role A and B in Domain X ~X.A

14. 25 June 201614 Dimensions or Attributes 3 Etiquette is Functional, yet Arbitrary  Functions (esp. of general etiquette) are common across cultures  Forms are arbitrary and varied  But forms must be adhered to within the ‘culture’ Etiquette constraints are “soft”  “Let’s dispense with protocol”  But may contribute to efficiency, ease, enjoyment, (safety). Etiquette-based behaviors can establish context or role Etiquette-based behaviors convey intentions and capabilities Etiquette violations will be disruptive, but occasionally useful Physical Characteristics Decreasing proportion of hard to soft constraints Social & Organizational Characteristics (including Etiquette) Individual Human Characteristics

15. 25 June 201615 The etiquette perspective in Design Acknowledges that computers and automation will be regarded as social actors (Reeves & Nass, 1996). Attempts to understand, predict and/or influence human+machine system behavior through attention to those social parameters Questions from the Etiquette Perspective If this system were replaced by an ideal human, how would (would we like) that human to behave differently? If a human were to provide this information/re- commendation/action in this way, how would s/he be perceived by colleagues?

16. 25 June 201616 Questions What is etiquette? What does it mean in Human-Machine interactions? How might we design for good HCI etiquette?  Now, with current technologies and applications  In the future Would it buy us anything if we did?  Is etiquette anything different from what we already do?  Will it provide sufficient added value to justify the cost?
