2
Specialized 3D stereoscopic display Silver-coated screen Dual projector setup with filtering Layers two monitor images atop one another
3
Glasses create “passive” 3D effect ◦ Each eye sees a different monitor UW – Agriculture building in WYGIS Only one UW professor uses it
4
GeoWalls help students understand trends/patterns effectively GeoWalls in place in 400+ universities
5
Faculty may be ◦ Unaware GeoWall exists / available ◦ Uncertain how to access / use GeoWall ◦ Intimidated by poor interface / controls
6
Point-click input for 3D imagery Current input unsatisfactory for 3D movement Navigating /manipulating 3D more difficult than 2D
7
If we can… ◦ Find a better input device ◦ Improve interface for software ◦ Faculty more comfortable using GeoWall ◦ Faculty more likely to use GeoWall
8
Found no identical research GeoWalls in education 3D interaction techniques / input devices ◦ 3D mice/ wands ◦ Touch ◦ Voice
9
Nyko Wii Remote ◦ Positive research exists ◦ Less buttons to remember ◦ Cheaper interface implementation ◦ Extensible to classroom use
10
alternative input device interface ESRI ArcGIS Software Bluetooth USB connect Wii Remote to PC GlovePIE programmable input emulator
11
Mapped keyboard / mouse input to Wii Remote Basic navigation ◦ Panning ◦ Zooming ◦ Rotating Mouse – joystick
12
Pre-evaluation focused on ◦ Attitude ◦ Encouragement of students toward GeoWall use ◦ Knowledge ◦ Interest
13
Post-evaluations focused on ◦ Attitude ◦ Encouragement of students toward GeoWall use ◦ Usability ◦ Comfort with system
14
three faculty participants one Atmospheric Science two Geography
15
Scores out of seven Only three faculty evaluated Two of three never seen / used Wii Remote ◦ Lower learnability, ease of use, comfort scores Efficiency4.00 +/- 0.82 Ease of Use3.82 +/- 1.85 Learnability3.88 +/- 1.83 User Comfort3.88 +/- 1.72 Errors / Problems6.33 +/- 0.47
16
Overall attitude change within standard deviation Not statistically significant High errors ◦ Interference / unfamiliarity Efficiency4.00 +/- 0.82 Ease of Use3.82 +/- 1.85 Learnability3.88 +/- 1.83 User Comfort3.88 +/- 1.72 Errors / Problems6.33 +/- 0.47
17
Most faculty totally unaware of GeoWall One asked about booking One commented positively on 3D quality
18
No attitude change Study itself may have increased awareness Less Wii Remote experience = greater difficulty Average usability System neither ineffective nor effective
19
Full-scale evaluation Fix interference issues Fix counter-intuitive implementation ◦ Zooming ◦ Panning Inform faculty of GeoWall before evaluation
