  1. Interactive Artifacts

  2. Shared Understanding &Mutual Intelligibility • Defines the field of social studies • Interpreting the actions of others • Goal is to come up with accounts of the significance of human action • Study how members of society accomplish mutual intelligibility of action • Relationship between observable behavior and processes that make it meaningful • Behavior/action can be part of indefinite number of meanings/goals • Goals can be achieved through indefinite number of behaviors

  3. Practical vs. Theoretical Goals of AI • Different meanings ascribed to Strong AI • Reasons in the same way as humans • Produce machines with an intelligence that matches or exceeds that of humans • Weak AI • Develop systems whose behavior appears intelligent regardless of how it is achieved • Perhaps deep understanding is required for either

  4. Interactive Artifacts • Computer as evocative object (Turkle) • Children’s view of computers as blending of • Physical: things we build, design, use • Social: things we communicate with • Interaction/communication implies mutual intelligibility • Need to answer how this works for humans before considering machines

  5. Cognitive Science and Automata • Mind viewed as neither substantial nor insubstantial but as an abstraction • Reflection -> behaviorism -> cognitive science • Combines discussion of • “beliefs, desires, symbols, schemata, planning, problem solving” with scientific method • Cognitive models proved sufficient on computers • Intelligence as the manipulation of symbols

  6. Human-Computer Interaction • History: • batch processing -> interactive computing -> shared languages • Uses terms from human interaction • Hayes/Reddy say difference is robustness • Ability to respond to unanticipated circumstances • Ability to detect and remedy troubles in communication • Said no graceful systems exist but components are there • Abilities cited are necessary but not sufficient • Work done was in limited domains • Is intentional vocabulary a shortcut?

  7. Should Interaction be Human-like? • Benefits • More natural • More accessible to those that are new to or shy away from technology • Costs • Might conceal miscommunication • May not allow taking advantage of strengths of partners • People have a tendency to assume more capability than shown to exist • Opaqueness of computer also results in reificiation

  8. Self-Explanatory Artifacts • Machines should be able to explain goals and relations of actions to goals • Self-explanatory as: • Obvious/discoverable, e.g. a hammer • Able to explain itself, e.g. training applications • Need to know when not to say things • WEST • Watched student and only interrupted when viewed appropriate

  9. Understanding Computers • Computer as artifact designed for a purpose • Increasing use of computers means increasingly complex technology should be usable with decreasing training • Purposes are not always obvious (e.g. archeology) • https://www.youtube.com/watch?v=YkK7wue2xGk

  10. Instruction as a Goal • Face-to-face training relies on specifics and context (different each time) • Tailored to current needs • Written instruction relies on generalization • Reusable for large number of people and situations • Interactive systems can be both reusable and individualized • Example of WEST

  11. Computers as Purposeful • Not just purposes of users or designers but having their own goals • Designer builds system to be accountably rational • History of Turing Test • Does not care about similarity of process • ELIZA as limited success (Weizenbaum denied intelligence) • DOCTOR (Rogerian therapist) – people assumed reasons even if none existed • Eliza conceals lack of understanding where “graceful interaction” requires it to be made explicit • https://www.youtube.com/watch?v=1uDa7jkIztw
