Desktop application (gesture interpreter)
Data displayer (in 3D)
Resource decoder
Aggregation decoder

4. Architecture

5. Each member’s contibution

7. Architecture
• Desktop application (gesture interpreter)
– Receives data (fingers/hands/gestures)
• From Leap Motion
• From Power Arm
• From GetMyo (if possible)
– Interprets it
– Sends an appropriate command to the 3D
displayer based on the interpretation

8. Desktop application
Leap motion
Get Myo
Power arm

9. Architecture
• Data displayer (in 3D)
– Receives commands from gesture interpreter
– Displays received data in 3D

10. Data displayer

11. Data displayer

12. Architecture
• Resource decoder
– Requests data from webservice based on user
input
– Parses the received data
– Gives it to 3D Data displayer

13. Architecture
• Aggregation service
– Requests data from multiple SPARQL endpoints
– Concatenates the results
– Sends them to the parser

14. Aggregation service

15. Sketches
-User “summons” a
virtual keyboard
- Types his/her query
using either the virtual
keyboard or the real one

16. Sketches
If the user joins his/her
thumbs, the
application displays
concepts related to the
requested data, as a 3D
graph

17. Sketches
The user will be able to
interact with some of the
information.
For example, if his/her
request returned a
picture, s/he will be able
to “hold” that picture via
a virtual hand that will
mimic his/her real hand

19. Small Demo
... it’s just a prototype
