32 2. RESULTS & CONCLUSIONS

33 TECHNICAL ESRI ArcGIS Projection set to local geographic coordinate system ( Belge Lambert 72 ) Georeferenced aerial photo POI point feature class from the personal geodatabase was added ( WGS 84 ) Transformation from WGS 84 to Belge Lambert 72 Adding new POI s features graphically ( sketch tool ) Copy OBJECTID (Arcmap) to accesid (ArcScript) and id (PorPOISe) using the Field Calculator Adding the longitude and latitude values using the Calculate Geometry tool Using the hyperlink tool clicking any POI will open the corresponding Microsoft Access form Microsoft Access Information on each POI can be added of updated Webpage within the Microsoft Access form show the location of the selected POI Updating the online MySQL database using Access To MySQL (freeware) Automatic alternative: DBSync for Access and MySQL (paid) 1 2 RESULTS & CONCLUSIONS

36 1 2 RESULTS & CONCLUSIONS Layar Realitybrowser

37 CONCLUSION Content 2D billboard images Hard to tell the direction of the photo Solution: experience domes / virtual caves 1 2 RESULTS & CONCLUSIONS Technical

38 CONCLUSION Accuracy Difference in geographic coordinate system ( Belge Lambert 72 vs. WGS 84 ) Minor deviation Inaccuracy is negligible (higher imprecision of GPS-signal) POI management Initial setting up of the system requires advanced technological knowledge Integrated in familiar workflows & ability to use existing GIS-data Much more functional in use then the PorPOISe server dashboard web interface Updating lat/lon fields and copying id-values should be automated 1 2 RESULTS & CONCLUSIONS Technical

39 CONCLUSION Screen size 1/ found the screen size to be a significant bottleneck Only two devices for twenty people Tablet pc s might be the solution (Apple ipad, Samsung Galaxy TAB, ) offer a greater immersive experience due to the significant lager screen size (MAARTEN, 2010) Impact on landscape perception 8% valued the landscape higher in terms of cultural heritage after using the application Educational use 2/ thinks AR is still too premature to have practical educational use Critical attitude towards educational (technological) innovation in general Multimedia or technology doesn t necessarily result in a better understanding of the learning content 1 2 RESULTS & CONCLUSIONS Quantative survey

40 CONCLUSION Mobile phones of students 40% have a mobile data plan Only a third has a smartphone All had Symbian (Nokia) as mobile OS: unsupported at the time Only 15% would pay over 200 for a new phone (critical price for an entry level smartphone) 2/ of female students get a new phone every year All of the male students use their phones at least two years, and are willing to pay more Greater confidence in educational opportunities is shown by male respondents Future All of the respondents would use this location based service to explore and learn more about the Ypres Salient area once finished 1 2 RESULTS & CONCLUSIONS Quantative survey
