17 ICE-CREAM Results Distributing Multimedia Elements to Multiple Networked Devices Maddy Janse, Peter van der Stok, Jun Hu Level of Control effect Significant differences in Spatial Presence, Engagement and Naturalness confirmed our expectations. No significant differences were found for the other Fun concepts. 8/14

18 ICE-CREAM Results Distributing Multimedia Elements to Multiple Networked Devices Maddy Janse, Peter van der Stok, Jun Hu Level of Control effect Significant differences in Spatial Presence, Engagement and Naturalness confirmed our expectations. No significant differences were found for the other Fun concepts. Effects of distribution Only Naturalness had been affected in both the LightingDistribution condition and the DisplayDistribution condition. Pride and Spatial Presence were significantly higher in LightingDistribution condition and not in DisplayDistribution. 8/14

Pride and Spatial Presence were significantly higher in LightingDistribution condition and not in DisplayDistribution. Number of Users effect The participation of a second user increased all the measurements of the Appeal questionnaire, but decreased the overall presence. 8/14

20 OZONE Integrated embedded platform architecture for consumer oriented ambient intelligence applications that provide content and context relevant information and services to users anywhere and at anytime. 9/14

21 OZONE Integrated embedded platform architecture for consumer oriented ambient intelligence applications that provide content and context relevant information and services to users anywhere and at anytime. a top layer for service enabling applications; a middle layer responsible for seamless task migration, and a bottom layer for high performance computing at a low power level. 9/14

22 OZONE Follow-me Distributing Multimedia Elements to Multiple Networked Devices Maddy Janse, Peter van der Stok, Jun Hu Link video content from one terminal to another and move around while maintaining the visual presentation on different terminals. 10/14

23 OZONE The linking concept The linking concept: several members of the same family want to watch the same video content on more receiving devices in more locations and at the same time. Connecting two or more receivers and to synchronize the same video content on the two devices. Proximity detection was used to initiate the receiving of video content by the second device. 11/14

24 OZONE Feedback from the users This linking concept was demonstrated and evaluated with users in a realistic home setting in the HomeLab of Philips Research: The linking concept was perceived as quite natural Perceived value: useful but skeptical Image quality was identified as one of the most important factors for acceptance of the system. 12/14

25 OZONE Feedback from the users This linking concept was demonstrated and evaluated with users in a realistic home setting in the HomeLab of Philips Research: The linking concept was perceived as quite natural Perceived value: useful but skeptical Image quality was identified as one of the most important factors for acceptance of the system. Crucial: the relationships between subjective acceptance of quality degradation and the optimal coding mechanism to apply. 12/14

26 Conclusion Evaluation of these applications revealed the following areas for promising new research: Assessment methodologies that operationalize multi-attribute concepts like fun and attractiveness, before we talk about user experience in general; Interaction with content by users in the home environment: Design and Evaluation; 13/14

27 Conclusion Evaluation of these applications revealed the following areas for promising new research: Assessment methodologies that operationalize multi-attribute concepts like fun and attractiveness, before we talk about user experience in general; Interaction with content by users in the home environment: Design and Evaluation; Distribution of ambiance effects in synchronization with or as a part of the content; Efficient configuring of scalable video and allocation of resources based on subjective quality evaluations.
