Description

[0001] Wearable recorder system and control method thereof [0002]

The present invention relates to a wearable recorder system, and more particularly, to a wearable recorder system configured to form clothing having a wearable sensor so as to collect and store data at the time of occurrence of an event, .

Wearable devices are the next generation mobile technologies that are expected to replace smartphones.

Wearable device means "electronic device to wear".

However, it is an electronic device that can communicate with the user at the nearest position of the user's body, rather than simply wearing the electronic device like an accessory.

The advantage of a wearable device is that it can continuously collect detailed information about the surrounding environment and the individual's body changes continuously in real time.

Smart eyewear, for example, can record all the information that is visible, and smart underwear can steadily capture vital signs such as body temperature and heart rate.

Wearable device research first began in the early 1960s at the MIT Media Lab, where research on early attachable wearable computing began.

Since then, a variety of prototypes have emerged in which devices are worn by the development of input / output devices and computing functions, and results are output using an input device on the hand or foot.

As ubiquitous computing emerged in the 1990s and electronic devices became lighter, it became possible to apply them in the industry in earnest. The development of computing functions has accelerated the speed, and the parts have been lightweighted so that they are not inconvenient to wear.

From the mid-2000s, research on special technologies such as fiber sensors, fiber circuit boards, bio-monitoring, and fire fighting military applications has been actively conducted. However, due to the lack of core application products and technical limitations, I have not been able to advance.

Attempts to expand wearable devices to full-fledged connected devices have begun to take place after the activation of smartphones, which is developing into a connected device type because of the limited competition with smartphones.

In this way, rather than being used independently, wearable devices are used in a way that information collected from wearable devices is exchanged in real time with each other through M2M (Machine to Machine) method using electronic devices such as smart phones.

This wearable device began to spread as a complementary element of the initial smartphone, but recently, it has become possible to connect with the network itself, and devices with enhanced scalability with devices other than smartphones have been introduced, There is no number.

Wearable devices are being made into clothing and miniaturized to overcome time and space constraints in a human-centered ubiquitous infrastructure, and wearable computer devices are worn in the form of fashionable computing such as clothing or accessory. Apply IT, BT, NT technology to clothing, ergonomics, design and fashion sense while wearing in-cloth.

Such wearable device technology includes hardware platform technology, user interface technology, context-aware technology, low-power technology, and near-field communication technology.

1 is a block diagram showing a general wearable device.

Most of wearable devices to which IT technology is applied are belt / head worn, wrist / finger / arm worn, implantable, And clothing based wearable devices.

Development of bio-clothing that requires acquisition and transmission of bio-information in a wide range of fields such as rapid remote treatment and prescription of emergency patients, human safety check of military personnel and dangerous environment workers, and alarm in case of danger are required.

However, the bio-signal measurement clothes up to now do not accurately reflect the human motion function in daily life, and there are many limitations in acquiring biometric information stably and accurately.

In particular, in the case of a wearable device such as that disclosed in Korean Patent Laid-open No. 10-2011-0005927, it is difficult to prove a suspicion when there is no accurate record in the case of friction or crime between individuals, There is no coping function for the structure and it does not satisfy the various demands of users and markets.
