1. Rotating, Tilting, Bouncing: Using an Interactive Chair to Promote Activity in Office Environments 1Probst, K., 1Lindlbauer, D., 1Greindl, P., 2Trapp, M., 1Haller, M., 2Schwartz, B., & 3Schrempf, A. 1Media Interaction Lab, University of Applied Sciences Upper Austria 2Medical Technology Department, University of Applied Sciences Upper Austria 3Mechatronics Engineering, University of Waterloo CHI EA '13 Work-in-Progress: CSCW

2. Outline • Introduction • Related Work • Implementation • Interactions • Challenges • Conclusion

3. Introduction (1/4) • A typical office worker nowadays spends the majority of his time sedentaryin the course of his working life chronic diseases prolonged sitting

4. Introduction (2/4) • Various possibilities have been proposed to keep people moving during the workday • For most office workers it is difficult to achieve a considerable reduction of the time spent seated within the office environment

5. Introduction (3/4) • Method : equipping a flexible office chair with motion sensing functionality • The chair provides an office worker with the possibility to use the movements of his body for tilting, rotating, or bouncing to control his workplace computer

6. Introduction (4/4) • we apply an existing gesture taxonomy to body movements on an active office chair & explore different application scenarios for ubiquitous gestural chair interaction

7. Related Work (1/2) • Existing sensor-based chair interfaces • Chairs • Chair-based tracking data • Usage of interactive chairs ChairIO SenseChair ChairMouse Sensitive Chair • Sensing Chair

8. Related Work (2/2) • Our work differs from past research : • Usage of an interactive chair within an office environment, with the goal to promote the implicit and occasional integration of light physical activity into the daily work routine • Chair interaction in the context of gestural interactions for the control of application-specific functions on a desktop computer

9. Implementation • 3Dee active chair • Nordic Semiconductor μBlueTM Smart Remote equipped with a gyro & an accelerometer • Desktop computer running Microsoft Windows 8 +gyroscope +accelerometer

10. Interactions (1/3) • We use the gesture taxonomy as a foundation for the proposed interactions to provide users with additional control, and to promote movement in a predominantly sedentary workday Five different gesture styles: deictic, gesticulation, manipulating, semaphoric and sign language

11. Interactions (2/3) • Gesture styles to categorize the proposed chair interactions • Deictic Gestures

12. Interactions (2/3) • Gesture styles to categorize the proposed chair interactions • Manipulating Gestures

13. Interactions (2/3) • Gesture styles to categorize the proposed chair interactions • Semaphoric Gestures

14. Interactions (3/3) • Gesture styles to categorize the proposed chair interactions • Other Interactions • Use the interaction chair as a presence sensor • Has information about the presence if the user is sitting at the workplace but not interacting with the computer

15. Challenges • Several challenges when working with gestures: • Fatigue • Non self-revealing • Lack of comfort • Immersion syndrome • Segmentation of (hand) gesture

16. Challenges • Several challenges when working with gestures: • Fatigue • Non self-revealing • Lack of comfort • Immersion syndrome • Segmentation of (hand) gesture

17. Conclusion • Using the chair as an additional input device has high potential to be a beneficial addition to traditional input devices and motivation of a more active daily work routine • we plan to evaluate the proposed interactions and compare them to regular interactions with mouse, keyboard and other input methods
