Who We Are
• Weareresearchers fromMonash University,workingonabroadrangeofresearchprojects,focusedinareasrelatingtoinformationgraphicsandtheuseofemergingtechnologiesforvisualisation andcomputerinteraction
• Accessiblegraphicshasbeenafocusofresearchforanumberofyearsnow,especiallyforKimandChatai
• Leonahasmanyyearsofpracticalexperience intheprovisionofaccessiblegraphics,atorganisations suchasVisionAustralia
What We Have Been Up To
• Wehavebeenengagedinanumberofresearchprojectsoverthepastfewyears,centeredaroundtheprovisionofaccessiblegraphics
• Thesehaveincluded:• Exploring theuseof tablettechnologyandhapticdevicesforauthoring,
delivering, andinteractingwithaccessiblegraphics(ARCLinkage)• Improving theprovisionofaccessiblegraphicsintheHigherEducation
context(OLTFunded)• Exploring3DprintingandeBooksintheprimaryschoolcontext(withInsight

3D Printing Projects
• Theseprojectshaveinvolvedanumberofaspectsrelatingto3Dprinting:• Exploring theuseof3Dprinting topresentinherently3D-basedgraphics• Exploring theuseof3Dprinting forpresenting2D-basedgraphics,suchas

How Can 3D Printing Help?
• Duringtheseprojects,wehaveobserved:• Widespreadenthusiasmwhenprovidedwith3Dprintedmaterials• Greatertendencytointeractwithandexploreagraphic• Ability tobetterunderstand inherently3D-basedobjectscomparedwitha
