Direct benefits of Linked Open Data
Gestural Interaction with Spatiotemporal Linked Open Data
13
• 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.

Evaluating the Approach

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!

Test Group •Participants: 43
•28 male•15 female
•Youngest : 10•Oldest: 59
•Left handed: 7•Right handed: 36
•Familiarity with gesture-based interfaces:
•Familiar: 19•Unfamiliar: 24

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.

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.

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.
