1. Application of G-Sensors Final project for extra project (will arrange a presentation in the last class)

2. Applications of G-Sensor Mobile Phone (photo browser) Game (Wii) Music Pacer ( 運動型 mp3 隨身聽 )

3. G-Sensor – OS5000 Data formats: – Roll, Pitch, Yaw, Ax, Ay, Az – E.g. -78.5,7.5,300.5,-0.993,0.133,0.15 – Ax, Ay, Az: 3 axis acceleration readings, x,y,z Sample rate: 20 sample/sec Reference: http://hscc.cs.nctu.edu.tw/jennic/manual/OS5000_Compass_ Manual.pdf http://hscc.cs.nctu.edu.tw/jennic/manual/OS5000_Compass_ Manual.pdf

4. Method of get samples Scenario: Steps: 1.Read sample via Uart1. 2.Write sample to your PC(via Uart0) or sink(using wireless). Set serial port of Jennic: – Buad rate : 19200 – Date : 8bit – Parity : none – Stop : 1bit JennicOS5000 Uart1 Uart0

6. Project Description (for bonus) Choose a specific action and log 3-axis acceleration samples measured by some G-Sensors. – Golfing, batting, pitching, exercise, aerobics, stretching, … Plot the corresponding waveforms. Make observation and analyze the behavior of the waveforms. Discuss a potential application of your results. – Give an example. – Possibly combined with existing techniques, e.g. GPS.
