This paper’s context-ware ability is limited to detecting participants’ speaking activities. Recording system constitutes of five parts: 1. Position-Fixed PC Camera 2. Microphone 3. Berkeley Motes 4. Monitor Screen Capture Program 5. PowerPoint Slide Change Recording Program In addition to the intelligent meeting room system architecture, this thesis creates a program for users reviewing meeting progress and retrieving meeting events.1 Introduction 1 1.1 Motivation 1 1.2 Previous Work 1 1.3 Related Work 6 1.3.1 UbiComp 05 Workshop 6 1.3.2 Smart Furniture 6 1.3.3 Integrated Control Panel 7 1.3.4 Sensor-Rich Environment 7 1.3.5 Event Driven System 7 1.3.6 Wireless Sensor Network 8 1.3.7 Ubiquitous Computing 9 1.3.8 Activity Recognition 9 2 Design of the Context-Aware Recording System 11 2.1 Problem Definition 11 2.2 A Scenario 11 2.3 Technical Challenges 12 2.4 The Proposed Solution 13 2.5 Features 14 3 Implementation 15 3.1 Meeting Room Environment 15 3.2 A General System Structure 15 3.3 Assumptions for Simplification 17 3.4 Implementation Architecture 18 3.4.1 Page Number Recording Program 19 3.4.2 Programming Berkeley Motes 22 3.4.3 Video/Motes Recording Program 24 3.4.4 Speaking Detection Module 27 3.4.5 Review Program 28 3.4.6 AVI Merge Program 29 4 Experiments and Analysis 31 4.1 Accuracy Calculation 31 4.2 Experiment Result 32 4.3 Analysis 33 5 Conclusion 35 5.1 Contribution 35 5.2 Future Work 35 5.2.1 Analyzing other kinds of data 35 5.2.2 Combination with a real-time control system 35 5.2.3 “Time Out” 35 Appendix 37 A.1 Introduction to Visual Basic Application 37 A.2 Introduction to Berkeley Motes 37 A.2.1 Background 37 A.2.2 Mote’s Operation System 38 A.2.3 Examples 39 A.3 Introduction of C# language 41 A.4 Introduction of Visual Studio .NET 42 A.5 Introduction of .NET Framework 43 Reference 442668067 bytesapplication/pdfen-US行為辨識環境感知會議室記錄系統Activity RecognitionContext-AwareMeeting RoomRecording Systemthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/54082/1/ntu-94-R91922113-1.pdf
