    Technology as MediationalMeans

    Remote versus Local communication

    Asynchronous versus synchronous

    Human to Computer to Human

    Technology provides the object,symbols, material to manipulate

    Need to learn the affordance of theinterface

    Improving Fidelity of HCI

    Signals Add gestural interface to complement

    symbol and voice commands.

    Initially only hand movement Future include facial expression

    Whole being Intelligence

    Intelligence is in the nervous systemas well as the brain

    Human judgment under uncertainty

    uses whole being intelligence Much information is ambiguous and

    vague

    Human comprehension is based onimpressions of patterns

    Interpretation of representations

    needs advances

    Augmenting HumanIntelligence

    HCI as a moderating socialengagement

    Two negotiating parties

    Fusing interpretations ofrepresentations

    Scenario

    Saul manipulates representationusing gestural interface

    Ava manipulated the system

    configuration Saul uses intuition to find patterns

    while Ava provides analysis to extract

    the material and representations The material is large scale rich

    information space needing discoveryand analysis to uncover patterns for

    decision making

    Finding the Story

    The scenario fosters story telling

    Pattern recognition has limitation

    People fill the gaps by creating ahidden narrative using interpretiveexplanation

    In business the story is left tointuition

    The intuition dominants decision

    making in real-world situations

    Dance of GesturalInteraction

    Discovery of the aesthetic ofrepresentation and expression thatfosters better augmented human

    judgment

    Archeology of knowledge as told bythe story of a social experience

    manipulating the material of richinformation spaces

    Research is needed

    Whole being intelligence

    Cognitive interfaces

    Improve Human to Computer toHuman social communications

    Adopt Gestural Interfaces to enhanceexpression

    Goal should be to improve humanjudgment under uncertainty wheninformation space is large
