Head-mounted system with human motion signal sensing

The present invention relates to a head-mounted system with human motion signal sensing, and more particularly to a head-mounted system with body motion signal sensing suitable for measuring the heartbeat of a wearer and detecting the action of the wearer.

The functions of glasses mainly include vision correction, eye protection, and styling, etc., and it has gradually become an important tool for individuals to protect their eyes in outdoor sports, such as cycling, skiing, running, climbing, surfing, and the like.

However, for the athletes, the heart rate change is the individual's individual sports index. According to the prior art, the related devices for the more common athletes' rhythm measurement on the market mainly include: the wireless transmission sports chest strap (chest belt) A transmitter, a wrist type or an arm type measuring device, and an ear-lobe type measuring device, etc., the principles, advantages and disadvantages thereof will be briefly described below.

First, regarding the wireless transmission of the chest belt transmitter, which is worn on the chest of the athlete, the electrocardiographic sensor (ECG or EKG sensor) on the chest strap is used to measure the change of the heart rhythm of the athlete. The voltage of the time, after signal processing, and by wireless transmission mode such as RF, Bluetooth, wifi, etc. The group is transmitted to other electronic devices, such as bicycle watches, smart phones or personal watches. However, since the athlete must wear the chest when measuring the heart rhythm, it often causes discomfort and inconvenience to the user, especially for women. In addition, the tightness is also a big key. Because a lot of ventilation is needed during exercise, the chest cavity will be greatly opened or contracted. If it is too tight, it will cause discomfort to the user, and may even cause difficulty breathing; but if it is too loose Will fall off, causing measurement misalignment.

Further, regarding a wrist type or an arm type measuring device, an optical sensing device is mainly used to measure a change in blood vessels caused by blood flow. However, due to the movement, the swing of the athlete's wrist and arm is quite frequent, and this will result in low accuracy of measurement.

In addition, with regard to the ear-lobe type measuring device, it is also the most conventional way to measure the change of the blood vessel caused by the blood flow in the earlobe portion by using an optical sensing device. However, as with the wrist or arm type described above, the dynamic measurement of the ear-hook measuring device during motion is very unstable and is only suitable for static measurement.

However, according to exercise physiology, when the human body carries out various types of sports, the head is always swinging or moving at least a part, because the neck of the human body is an optimal buffer, and the movement of other parts of the human body during exercise. It has been isolated as much as possible under the neck, so measuring the heart rhythm from the head should be an excellent solution.
