Transcript

  • 1. The influence of applied cartographic methods on the map information perception quantification for various groups of users Alena VONDRÁKOVÁThis presentation is co-financed by theEuropean Social Fund and the statebudget of the Czech Republic
  • 2. Principal points of research  lack of standardization or mandatory rules in cartography  choice of method of cartographic visualization depends on the opinion of the map author  way of expressing the same information by different methods of cartographic visualization leads to different user perception  what can affect the perception of the map  age, sex, education, previous experience, actual mood...  maps have to help their users to better understand geospatial relationships, not to confuse the user  users have to get the information as quickly as possible and as accurately as possible First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 3. Methods of cartographic visualization  set of rules to express the spatial characteristics in the map  often referred as: methods of representation, means of expression, interpretive methods, graphical representation, mapping expression, etc.  many ways of distribution and classification of these methods primary classification: point, line, area thematic classification: physical- and socio-economic geography thematic methods: choropleth, isarithmic , dot density, dasymetric, topographic... type of material: tactile 3D, plastic, paper, metal... type of presentation: digital, analog, on-line, off-line...  representatives of the Czech cartography: Voženílek, Veverka, Konečný, Kaňok, Čapek, Drápela, Murdych... First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 4. Map information perception Ways in which maps are read by users are crucial determinants of the effectiveness of such maps. Board and Taylor, 1977 the influence of using different cartographic methods of visualization on the information perception from a map is something, that objectively exists map information perception is individual our aim is to objectify and quantify this user aspect one of the possible solutions is offered by technology of eye-tracking First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 5. Realization of the study  SMI RED 250  120 Hz, resolution 1680 × 1050 px First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 6. Realization of the study First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 7. Realization of the study SMI Experiment Centre™ BeGaze™ Analysis software First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 8. Realization of the study Statistical evaluation  AOI characteristics, fixations, saccades, mouseclicks... First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 9. Realization of the study Visual evaluation HeatMap GazePlot First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 10. Realization of the study Individual interpretation BeeSwarmScanPath First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 11. Realization of the study Comparison of respondents First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 12. Realization of the study Group evaluation First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 13. Preliminary results Data processing First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 14. Preliminary results minimal influence of gender on the response time in total cartographers answered one second faster woman response was also one second earlier than man response First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 15. Preliminary results influence of cartographic education is significant difference in correct answers is 12% in cartographic education and 5% between gender (women were more succesfull) First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 16. Significant differences difference between cartographers and non-cartographers problems with contour lines, choropleth map and diagram map First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 17. Preliminary results  the most suitable for the presentation of terrain was method of colour hypsometry  for the presentation of socio-economic data of uneployment was the most appropriate diagram map  for the presentation of demographical characeristic was the most suitable method of diagram map  big influence has also the choose of the type of chart First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 18. Conclusion  some questions seems easy and in the result they are the most difficult for respondents  there are significant differences between sub-groups of respondents identified by sex or cartographic education  we can train people how to read maps – but can people train cartographers how to create maps?  it is needed to validate maps  it is needed to take into consideration the user aspects First InDOG Doctoral Conference, 29th October - 1st November 2012, Olomouc
  • 19. Discussion  future tasks  to make this experiment with regard to the age of respondents  try to identify control mechanism in user behaviour (time of verifikation answers that the user find some time period before the mouseclick – such as control of other possibilities in AOI)  Using appropriate visualization methods can significantly reduce the time needed for obtain required information. Maps help their users to better understand geospatial relationship...
