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: 43 28 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

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
