  1. •  Introduction & Background •  Mapping at NASA •  Sharing

    Symbology •  Evaluating Symbol Sharing Tools at NASA •  Study Results & Conclusions
  2. •  SEARCH •  RETRIEVE •  REVIEW •  DOWNLOAD •  UPLOAD

    •  METADATA •  CATEGORIZE •  REVIEW
  3. Study Objectives: •  Can users successfully upload symbols? •  Can

    users successfully categorize symbols? •  Can users successfully add metadata to symbols? •  Can users successfully review symbols after they have been uploaded? •  Can users identify usability/utility issues with the tool? Task Analysis Study to Determine: •  Error/Success Metrics •  Subjective Ratings of the Symbol Store
  4. Study Procedure - 4 Phases: 1.  Structured interview 2.  Written

    tasks and semi-structured survey 3.  Perform tasks and complete Likert-scale survey questions 4.  Compile/analyze results
  5. Publishing symbols in the Symbol Store was Easy. “I was

    expecting to add more symbols and then fill in all of the metadata at once.” “I selected the wrong image accidentally…a preview option would have been a red flag that my symbol was too big.”
  6. “I was unable to publish symbols on my computer.” “Neither

    ‘most recent’ nor any searches I attempted exposed my symbols.” “Keyword and tag, what is the difference?” “Would be nice to provide a brief sample.”
  7. •  All users were able to successfully preview symbols on

    realistic maps using the map preview tool. I was able to retrieve symbol(s) using the ‘Search By Category’ feature. I was able to add symbol(s) to the symbol cart.
