1. CloudRoom: A Conceptual Model for Managing Data in Space and Time Lucia Terrenghi, Thomas Lang, Martin Richartz Vodafone GROUP R&D Kátia Serralheiro Human-Computer Interaction Institute Carnegie Mellon University CHI 2010, April 10–15, 2010, Atlanta, Georgia, USA. ACM

2. Outline Background and motivation Cloud computing and user experience Challenges and design rationale The Cloudroom Related work and discussion

3. Background and motivation Cloud, Real time. Everything, Every time. A new interface. Raising a constructive discussion. user experience and mental model.

4. Cloud computing and user experience 1/3 Iterations of qualitative user studies. Through out these activities main goals were to ： 1.Current practice of storage and sharing of data. 2.How data is accessed and used across an ecology of devices. 3.Investigate motivation and barriers of using web applications.

5. Cloud computing and user experience 2/3 Structure their data into thematic folders. Folders are labeled with specific name. Trade-off between safety and accessibility. Automated organization would be desirable.

6. Cloud computing and user experience 3/3 People prefer using portable device. Different situation for different requirement. Share ability and collaboration.

7. Challenges and design rationale 1/3 Designed a concept which tackles the following challenges: 1.A trade-off between ownership and delegation of control. 2.An ecology of devices.

8. Challenges and design rationale 2/3 Made the following assumptions : – The time emerged as a key criterion. – Using phone to shared data. – ‘Cloud views’ across devices. Designed the Cloudroom.

9. Challenges and design rationale 3/3

10. The Cloudroom 1/6 Structure, manipulate, retrieve and share. The concept is based on three dimensions.

11. The Cloudroom 2/6 First, the long-term storage for the organization of data in a certain location.

12. The Cloudroom 3/6 Second, the short-term manipulation of data in temporary sessions.

13. The Cloudroom 4/6 Third, the overview through time.

14. The Cloudroom 5/6 Time and space. Mobile device as the starting point of interaction. Multiple sessions in parallel. Provides an overview of the evolution of all data.

15. The Cloudroom 6/6

16. Related work and discussion A list visualization with hierarchical structure. Users can’t determine the number, type or size of the data within folders. To facilitate spatial orientation. User behaviors and technology trends – User interfaces for cloud computing.
