5 Name: Jim Jones Gestural Interaction with Spatiotemporal Linked Open Data 5

6 Name: Jim Jones Deforestation decreasing : km² 2012: km² (Awesome!) Gestural Interaction with SpatiotemporalLinked Open Data 6 Known Issues  Data produced queued for analysis (Huge amounts)  Hard to visualize  Hard to correlate the produced data with external variables.

7 Name: Jim Jones Motivation Gestural Interaction with Spatiotemporal Linked Open Data 7 How to efficiently correlate the deforestation phenomena with external variables? How to effectively communicate it to the population?

8 Name: Jim Jones Triangle of Sustainability ● Wissenschaft Interaktiv 2012 (Interactive Science) ● Awarded with €10k for developing the project ● 4 weeks for development! Gestural Interaction with Spatiotemporal Linked Open Data 8 Linked Open Data!

9 Name: Jim Jones What is Linked Data? (In 2 minutes) Gestural Interaction with Spatiotemporal Linked Open Data 9

10 Name: Jim Jones The Web Gestural Interaction with Spatiotemporal Linked Open Data 10 Awesome Discoverability! But just for humans :(

11 Name: Jim Jones Semantics Gestural Interaction with Spatiotemporal Linked Open Data 11 ? The forbidden fruit Xxx xxxx x xxxx xxx xxxx Xxx xxxxxxx xx x x xxxxxxxx. Cheers, -God ● What is the article about? ● Who is the author? ● What is inside the picture? ● Where, when and by whom was the picture taken? ●...

12 Name: Jim Jones Linked Open Data Gestural Interaction with Spatiotemporal Linked Open Data 12 “linked open data describes a method of publishing structured data so that it can be interlinked and become more useful.” Raw Data now!

13 Name: Jim Jones Gestural Interaction with Spatiotemporal Linked Open Data 13 ID 1 (Uniquely Identified) ID 5 ID 3 ID 4 ID 2 ID 6

14 Name: Jim Jones Some benefits of Linked Open Data Gestural Interaction with Spatiotemporal Linked Open Data 14 Attaches meaning to data Allows efficient thematic searches (e.g. person, company, city, book, etc.) Links different kinds of datasets making the WORLD a single big repository! Private data and public data can be mixed, enabling companies and individuals to make better decisions and generate innovations. My Repository

15 Name: Jim Jones Creating Dataset... Gestural Interaction with Spatiotemporal Linked Open Data 15 Deforestation Soybeans Crops Cattle GDP Population Brazilian Municipalities' Area Download data from IBGE Servers Create Triples

16 Name: Jim Jones Dataset Vocabularies Time and Space Core Vocabulary (TISC) Open Linked Amazon Vocabulary (OLA) Gestural Interaction with Spatiotemporal Linked Open Data 16 Spatiotemporal Dataset ● Aggregated in grid cells of 25km x 25km ● Time-series

17 Name: Jim Jones Motivation (Recap...) Gestural Interaction with Spatiotemporal Linked Open Data 17 How to efficiently correlate the deforestation phenomena with external variables? How to effectively communicate it to the population? Gestural Interaction with Virtual Globes!

21 Name: Jim Jones Video ( +1 minute) Gestural Interaction with Spatiotemporal Linked Open Data 21

22 Name: Jim Jones Evaluating the Approach Gestural Interaction with Spatiotemporal Linked Open Data 22

23 Name: Jim Jones Evaluation Procedure and Material 5- 8 Minutes usage Questionnaire with 28 questions in two groups: 1 group: demographic information e.g. gender, age, primary hand, familiarity with gesture control interfaces 2 group: Task Load (NASA TLX – Task Load Index). Rating how well gestures and map actions fit together, from 0 to 20. e.g. In which scale you define the mental or physical workload for the gestures? No reward! Gestural Interaction with Spatiotemporal Linked Open Data 23

24 Name: Jim Jones Test Group Participants: male 15 female Youngest : 10 Oldest: 59 Left handed: 7 Right handed: 36 Familiarity with gesture-based interfaces: Familiar: 19 Unfamiliar: 24 Gestural Interaction with Spatiotemporal Linked Open Data 24

25 Name: Jim Jones Results Gestural Interaction with Spatiotemporal Linked Open Data 25

26 Name: Jim Jones Observations Most participants reported the gestures as mentally challenging in the first minutes Older people found the system very accessible, particularly when compared with their first time using a mouse. User recognition gets considerably affected when bystanders are ‘seen’ by the Kinect sensor. Gestural Interaction with Spatiotemporal Linked Open Data 26

27 Name: Jim Jones Software Gestural Interaction with Spatiotemporal Linked Open Data 27 Virtual Globe (UI) LOD Processing Gestures (Kinect) https://github.com/giatschool/triangle-of-sustainability

28 Name: Jim Jones Hardware Gestural Interaction with Spatiotemporal Linked Open Data 28

29 Name: Jim Jones Triangle on Tour! SBPC Science Fair Recife (August, 2013) KIT-Alumini Club Seminar Recife (September,2013) GeoCamp Campos do Jordao (November, 2013) Ecogerma Belém (November, 2013) Gestural Interaction with Spatiotemporal Linked Open Data 29

30 Name: Jim Jones Conclusion The triangle provides an attractive and easy to use solution for displaying spatiotemporal LOD. It has a high acceptance in class-rooms (Already presented in many German schools) Participants were able to learn how to use 3 gestures without excessive workload. Linked Data offers a good bases for efficiently connecting deforestation data with external variables. Gestural Interaction with Spatiotemporal Linked Open Data 30

31 Name: Jim Jones Future Work Improve registration gestures Inefficient when more than one person is in front of the sensor Try different Kinect frameworks. Enable registration by children (short people) Minimum arm length problem. Gestural Interaction with Spatiotemporal Linked Open Data 31
