WHO ARE WE?

• DEHAES (Development of DIGILAB is a MULTIDISCLIPINARY S ( e e op e o Spatial Skills Research Group),

DIGILAB is a MULTIDISCLIPINARY group that works in differentáreas of research:• Development and

• Spatial ability is a key element tostudents’ success in science,technology engineering and

SPATIAL ABILITIES• The development of spatial skills by engineering students is directly linked to their

future success in their professional work (Mc Gee, 1979; HIS, Linn, and Bell 1997;Miller 1996; Smith 2002)Miller 1996; Smith 2002)

• A survey performed in 2004 by the Engineering Design Graphics Division of theAmerican Society for Engineering Education concluded thar the “ability tocreate 3-D solid computer models” and the “ability to sketch engineeringcreate 3 D solid computer models and the ability to sketch engineeringobjects in the freehand mode” were the two most important graphicalcommunication outcomes for engineering students (Barr, 2004). Several authorshave concluded that these skills also are related to spatial abilities.

• At Michigan Technological University (MTU), Professor Sheryl Sorby conducts along research about the relationship between skills and success in engineeringstudies. She published a book with paper and pencil excercises to develop 3Dspatial visualizationspatial visualization.

• Our research group (DEHAES) have always tried to use advanced, but easy touse, graphics technologies to make the relation between 2D and 3D moreattractive to students. We started in 2004 with web/flash applications,attractive to students. We started in 2004 with web/flash applications,calligraphic interfaces, and in year 2006 we discover SketchUp, .

WHY SKETCHUP?

• Easy to download and to install. Multiplatform • Intuitive 3D environment easy to learnIntuitive 3D environment, easy to learn• Robust. It runs without hanging out. Not a prototype for

investigation.• Free version

P ibilit f bi i f ti i 2D ith 3D • Possibility of combine information in 2D with a 3D environment (using masks)

• Easy to implant in educational centers (not only in university levels but also in pre university levels)university levels but also in pre university levels)

• It´s a very simple way to understand the relation between a 3D model and the 2D orthogonal views.

• Lots of plugins to add functionalities• Its allows more than interaction, allows creationWEAKNESS• No version for mobile devices (IOS/ANDROID)

( )PHYSICAL (TANGIBLE) MODELS

Handling physical models has been demonstrated useful for the student’s

development of the transfer ability from 3D reality to 2D orthogonal views development of the transfer ability from 3D reality to 2D orthogonal views

Physical Models present some problems:Physical Models present some problems:

• Teachers have to transport them.

• Control that all parts return to their Control that all parts return to their

containers at the end of the class.

• These collections of parts, especially the These collections of parts, especially the

metallic ones, are expensive.

WHY AR-MEDIA PLUGIN?

• Competitive price.• Direct link with sketchUp, giving complete

autonomy to create 3D contents in RA No other autonomy to create 3D contents in RA. No other person (programmer) or company is required to generate RA contents.

• Therefore this plugin make easier the • Therefore this plugin make easier the implementation in education environments. (primary and secondary school and university)
