BACKGROUND ART

Obesity has recently become the leading threaten of health worldwide, mainly because of changes in lifestyle and diet nowadays. With increasing prevalence of obesity, which induces various cardiovascular diseases, type 2 diabetes, and even certain types of cancer in population, authorities has started emphasizing the importance of weight control. According to medical researches and nutritionists, adequate exercise is considered as an appropriate way of weight control instead of dieting. However, the ideal quantity of exercise varies depending on factors such as gender, age, smoking, gene, and body mass index (BMI). To quantify exercise intensity, people usually use sensing devices while exercising to gather numeric information, and further optimize exercise plans by that information.

One of the most common sensing devices is pedometer. A pedometer was positioned about a user's hip and counts each step the user takes by detecting the motion. An advanced pedometer also monitors distance, velocity, heart rate, and calorie burned of a user. Another example of a sensing device is sport watch. Some sport watches are capable of monitoring distance, duration, heart rate, and calorie burned of an exercise; they are also capable of operating under different situations including walking, running, cycling, or marathon.

With development of new technologies, the size and the shape of these sensing devices are greatly varied and mostly were designed to a watch-like style to be easily carried with a user. However, functions of these sensing devices are limited. A pedometer is only suitable for walking and running, which may not satisfy the demands from people with active lifestyle. A sport watch is compatible with several different exercises, but the interaction is restricted between the user and the sport watch. As a result, a user may refrain from experiencing all the benefits of the sensing device.

The operation process of tracker comprising the steps of: A. a sensing unit 11 which has detected movements generates an acceleration signal; B. a first processing unit 10 which has received the acceleration signal switches at least one operating mode; C. the sensing unit 11 which has detected the movements generates a motion signal; D. the first processing unit 10 which has received the motion signal generates a feedback signal and stores the feedback signal into a memory unit 12; the first processing unit 10 further displays the feedback signal via a user interface 13; E. a wireless transceiver 14 connected to a wireless network 2 transmits the feedback signal stored in the memory unit 12 to a receiving device 3; F. a control unit 31 comprised in the receiving device 3 receives the feedback signal and transmits the feedback signal to a second processing unit 32; G. the second processing unit 32 received the feedback signal displays the feedback signal via a display 33.

Once a user taps the tracker 1 to initiate the mode switching process, the sensor unit 11 starts to detect movements and generates acceleration signals to the first processing unit 10; the first processing unit 10 switches the operation mode to basic mode, walking mode, cycling mode, sleeping mode, swimming mode, or synchronization mode based on the acceleration signals. If there is no movement detected by the sensing unit 11 in a period of time, the operation process of tracker 1 stops processing automatically; if the sensing unit 11 detects movements and generates motion signals, such as a walking signal, a stair-climbing signal, a cycling signal, a sleeping signal, and a swimming signal, to the first processing unit 10; the first processing unit then converts the motion signals into feedback signals, such as steps taken, distance traveled, stairs climbed, calories burned, cycling speed, swimming type, or heart rate, and stores the feedback signals into the memory unit 12; the first processing unit may further display the feedback signals on a user interface 13.

The sensing unit 11 may be one selected from the group consisting of a gyroscope, an accelerometer, and an infrared sensor. The heart rate mentioned here may be detected by an infrared sensor, wherein the infrared sensor is able to detect an infrared light which has penetrated a vessel and been reflected by bones. Due to the reason that the pulsing of blood flow in the vessel may interfere the penetration of infrared light, the infrared sensor may detect the variation of infrared light and pass this information to the processing unit 10 for computing. The processing unit 10, then, computes the heart rate based on this information.

To display the feedback signal on a receiving device 3, the operation processing of tracker 1 is switched to synchronization mode and starts streaming the feedback signal to the receiving device 3. Under synchronization mode, the tracker 1 sends the feedback signal stored in the memory unit 12 to the receiving device 3 via the wireless network 2 by a wireless transceiver 14; wherein the wireless transceiver 14, connected to the memory unit 12, may be one selected from the group consisting of a WiFi transceiver, a Bluetooth transceiver, and a near-field communication (NFC) transceiver. Once the second processing unit 32 in the receiving device 3 receives the feedback signal, the second processing unit 32 may display the feedback signal by a display 33.
