These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with one embodiment. It is also to be understood that the position or arrangement of the individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

Hereinafter, a system for exchanging an electronic business card, which is a new business card that is out of the existing paper business card scheme, is disclosed in the embodiment of the present invention. Hereinafter, the exchange of electronic business cards is mainly started, but other personal information other than business cards may be exchanged using the same method, and these embodiments are also included in the scope of the present invention.

The user creates an electronic business card (or digital business card) based on the application of the user device, and the created electronic business card can be transferred from the user device to the user's wearable bracelet and stored. Electronic business cards stored in a wearable bracelet can be exchanged with a simple touch based on near field communication (NFC) communication that does not require paring. Therefore, exchange and management of electronic business cards can be performed simply and efficiently. By using this method, personal information can be stored and managed based on electronic business cards instead of paper business cards.

In the embodiment of the present invention, NFC communication can be used for quick business card exchange. Conventional Bluetooth has advantages in use range and frequency. However, there is a disadvantage that the setup time for Bluetooth-based communication is long. Such a long pairing time can quickly prevent electronic business cards from being exchanged. Thus, an NFC communication scheme can be used for simple and efficient exchange of electronic business cards.

* Table 1 below shows differences between existing Bluetooth and NFC.

<Table 1>

Referring to Table 1, in addition to set-up time, conventional Bluetooth has a large difference in power consumption as compared with NFC communication. Currently, Bluetooth 4.0, a low-power Bluetooth, has been proposed to solve this power consumption problem. However, Bluetooth 4.0 also has problems.

In Bluetooth 4.0, improvements in setup time and multi-pairing support have greatly improved the disadvantages of the existing Bluetooth. However, Bluetooth 4.0 is no longer available on existing smartphones in the prevalence stage. Also, tag price is about 50 times different from NFC. Therefore, Bluetooth 4.0 can not follow the advantages of NFC in terms of economy. Because of this difference, NFC communication can be performed for business card exchange.

Table 2 below compares Bluetooth 4.0 with NFC.

<Table 2>

The NFC-based personal information exchange method according to the embodiment of the present invention can be performed for exchanging personal information when a device capable of NFC communication operates within a distance of 10 cm by operating in a P2P mode. By performing NFC-based communication, accurate exchange can be achieved without any error or loss of data when exchanging personal information.

In the second communication, The first wearable device can perform the role of the receiver, and the second wearable device can perform the role of the sender by reflecting the adjustment performed during the first communication between the wearable devices.

5 is a conceptual diagram illustrating a method of analyzing a business card image in a business card generation application according to an embodiment of the present invention.

FIG. 5 illustrates a method of extracting personal information included in a business card by analyzing a captured card image.

Referring to FIG. 5, a name is extracted from a business card image (step S500).

In general, a name part in a business card can be a sequence of two to four consecutive characters of the same font. Thus, the business card creation application can extract text from the business card image. The business card creation application may store a text template for analysis of various texts, and extract and analyze text information by comparing with a text template. The business card creation application can estimate the name of text with high relevance ranging from 2 to 4 characters among extracted text. Highly relevant text may be text positioned consecutively in the same text format. In addition, it is possible to additionally determine whether or not the text that precedes the most preceding text is a text (e.g., Kim, Lee, Park, Choi, etc.) that can be used as the last name so that the name can be extracted from the card image.

And extracts from the card image (step S510).

The business card image may include information about the user. The business card creation application can extract numbers from the business card image and estimate the set of numbers for a format with a similar range of fonts to the phone number. The format may be, for example, 010-xxxx-xxxx, 02-xxx-xxxx, or a format that can generally be used as a telephone number.

The business card creation application may have a format template stored therein for extracting and may be extracted and analyzed through comparison with the format template.

An address is extracted from the card image (step S520).

The business card creation application can determine a set of texts corresponding to an address of the text extracted from the business card image. The business card generation application can determine a text set (a set of texts existing in the same font, a similar-range position) including a place name used as an address as a text set corresponding to an address. For example, a text set including texts representing geographical locations such as city names such as Seoul, Daejeon, and Daegu, and similar names such as Yeoksam-dong and Apgujeong-dong may be determined as addresses.

The affiliation name is extracted from the business card image (step S530).

The business card creation application can estimate the text information having the largest font size or the next font size among the text information extracted from the card image as the affiliation name. Alternatively, the business card creation application may determine a non-black text image based on the color of the text image as the affiliation name. Alternatively, the business card creation application may concatenate with the image, not the text, to determine the text represented by the affiliation name.

In FIG. 5, a method of extracting personal information (name, telephone number, address, affiliation name) from a card image based on an estimation of only a card creating application is disclosed. However, it is also possible to extract personal information from the card image based on the user's additional input signal. For example, the business card creation application can request the user to select a portion of the business card image corresponding to the name. In this case, the user can touch the screen on which the business card image is printed to select the image portion corresponding to the name . In the same manner, the business card creation application can request the user to select a portion of the business card image corresponding to the telephone number, address, affiliation name, etc., and the user makes a selection for the corresponding portion, Personal information can be extracted through analysis.

6 is a conceptual diagram illustrating a method of managing a business card list according to an embodiment of the present invention.

 In FIG. 6, the business card information list may be managed in various manners so that the user can quickly find the stored electronic business card.

For example, information on a business card exchange date (or a business card storage date) and a business card exchange place corresponding to a business card stored in the business card information list may be additionally allocated as tag information.

The user can search for stored electronic business cards as well as search for name information, as well as the business card exchange date and business card exchange location. For example, in the case of a business card that has been exchanged by meeting in Gangnam, when entering 'Gangnam', only an electronic business card exchanged in Gangnam can be separately extracted from the electronic business cards included in the list.

As another example, when a business card exchange date (for example, Nov. 18) is input, only the electronic business cards stored at 11.18 days among the electronic business cards included in the list can be separately extracted.

FIG. 7 is a conceptual diagram illustrating a method of exchanging a business card with a multi-party electronic card according to an embodiment of the present invention.

7, a method for exchanging electronic business cards by three or more persons is disclosed.

When the number of persons (N> 2 persons) to exchange electronic business cards increases, communication of 1: N should be performed N times. Therefore, as the number of people increases, the communication efficiency decreases and the time for information exchange may increase. Therefore, in this embodiment of the present invention, the exchange of electronic business cards can be performed by setting one wearable device as a master node (master node) 700.

For example, it can be assumed that five persons (i.e., five wearable devices) exchange electronic business cards with each other. In this case, one wearable device may be set as a master node 700, and the remaining four wearable devices may be set as a servant node 750. The setting of the master node 700 and the servant node 750 may be automatically set or may be performed through setting of a menu provided in the wearable device.

The four wearable devices (servant wearable devices) corresponding to the four servant nodes 750 can transmit their electronic business card information to one wearable device (master wearable device) corresponding to the master node 700. [ The master wearable device 700 can store a plurality of electronic business card information received from the four servant wearable devices 750. [ Then, the master wearable device 700 can transmit the electronic business card set information including the electronic business card information to the received plurality of electronic business card information to the four servant wearable devices 750.

Although the electronic business card set information may be broadcast to the four servant wearable devices 750 as the same information, the electronic business card set information excluding the electronic business card information corresponding to the receiving end may be unicasted to each of the four servant wearable devices 750 It is possible.

By using this method, it is possible to reduce the number of communications and reduce the probability of error that may occur in communication, thereby increasing the information transmission efficiency.
