1. X-Mind Pilot Project Proposal 許志毓、李俊輝、吳蕙盈、卓曉青

2. Outline Topic of Interest Research Aims Details & Workflow Work Distribution Challenges & Conclusion

3. Topic of Interest TopicAimsWorkflow Work Distribution Discussion Photo-taking activities on the smartphone Learning curve of photo-taking on smartphones Types & combination of photo-taking applications used, frequency Understand the relationship between user and phone through photo-taking activities

4. Research Questions Do users generally develop a certain model of photo-taking during their first six months (or one year) of using smartphones? How long does it generally take for the user to develop a more “stable” or “routine” photo-taking habit? How does the user perceive their own photo-taking behavior as compared to the analyzed results? TopicAimsWorkflow Work Distribution Discussion

5. Research Aims Conduct a complete (pilot) research project using the X-Mind userlog platform Develop suitable tools that will assist such a pilot research Develop tools that may be used in future related research topics Find possible future research projects (optional) TopicAimsWorkflow Work Distribution Discussion

7. Project Details ( 志毓 ) Data Collection: Gain log files of first six months of photo- taking application installation/usage/uni nstallation for #number users. TopicAimsWorkflow Work Distribution Discussion

8. Data Collection Log Search Interface Purpose: aid researchers to find the UserLog data in database what they wanted. Search: UserID, Time_Stamp, time interval, Name of an application, or activity name Form: Blanks for each attribute and researchers can input to the blank what they are interesting

9. Project Details (Helen) Visualization: Show the usage patterns of the photo- taking applications, frequency and trends. TopicAimsWorkflow Work Distribution Discussion

10. Visualization Google Chart Tools API Purpose: Provide an interface to select and visually display simple statistics of the log files

11. Project Details (Scott) API/Model: Observe parameters (usage amount, usage period…etc.) to propose specific models of photo- taking Group users according to the proposed models TopicAimsWorkflow Work Distribution Discussion
