In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch" The act of actually touching the pointer on the screen is called "Contact Touch ". A position where the pointer is proximally touched on the touch screen means a position where the pointer corresponds to the touch screen vertically when the pointer is touched.

Further, the proximity sensor 141 detects a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, do. Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

The sensing unit 140 may include an acceleration sensor 142. The acceleration sensor 142 is a device that converts an acceleration change in one direction into an electric signal and is widely used along with the development of MEMS (micro-electromechanical systems) technology. Since the acceleration sensor 142 measures the acceleration of a large value that is built in the airbag system of an automobile and used to detect a collision, the acceleration sensor 142 recognizes the minute motion of a human hand and calculates a minute value acceleration There are various kinds of things to measure. The acceleration sensor 142 is usually configured by mounting two or three axes in one package. In some cases, only one axis of the Z axis is required depending on the use environment. Therefore, when the acceleration sensor in the X-axis direction or the Y-axis direction is used instead of the Z-axis direction for some reason, the acceleration sensor may be mounted on the main substrate by using a separate piece substrate.

Referring to FIG. 7, a method of searching for a product of a mobile terminal according to the present invention includes a step of inputting a search condition (S100) for inputting a search condition, an information receiving step of receiving product information from a communication tag An offline search step S300 for comparing the product information with the search condition to search for a product corresponding to the search condition; and a result display step S400 for displaying an offline search result of the offline search step ). The construction of the apparatus will be described with reference to Figs. 1 to 6. Fig. The condition input step S100 may include a step of storing a search condition input by the user (not shown).

For example, as shown in FIG. 4, the mobile terminal inputs a price of 0 to 1,000,000 won, a color, a size of medium and a large size, a Galleria department store, a Hyundai department store, and a kind of a shoulder bag as search conditions (S100). The mobile terminal receives the goods information from the communication tag (for example, NFC Tag) embedded in the goods (S200), compares the search condition with the goods information (S300) And displays it as shown (S400). The mobile terminal can use Bluetooth, RFID, infrared communication, UWB, ZigBee as well as near field communication technology as the short distance communication module in order to receive the product information from the one or more goods using the short distance communication module (S200) . The mobile terminal searches for goods corresponding to the search condition using the goods information, and outputs the result (offline search result) (S300). Here, the mobile terminal can generate an alarm signal and notify the user when a product corresponding to the search condition is searched. The mobile terminal displays the offline search result on the screen. The mobile terminal displays the condition set by the user, that is, each category, and also displays information on the goods received from the goods such as a search keyword, a product name, a lowest selling price, and a selling place (S400).

8, the product search method includes an online connection step (S610) of accessing a device or a web site in which the goods information is stored via a mobile communication network or a wireless Internet, a search signal for the search condition, And an online search step (S620) of receiving an online search result corresponding to the search condition. Here, the result display step S400 may display the offline search result or the online search result or simultaneously display the two search results (S410).

The mobile terminal accesses an Internet site, a store site, a search site, etc. using a mobile communication module or a wireless Internet module (S610), searches for products online and receives product information (S620) And the online search result is displayed on the screen (S410). Here, the mobile terminal can distinguish whether an online search result or an offline search result is displayed by using an icon (B1 in FIG. 6A) or the like. The mobile terminal may store an offline search result, an online search result, and the like in a memory along with a search condition.

Referring to FIG. 9, the mobile terminal accesses a social network service through a mobile communication network or a wireless Internet (S630), and transmits product information or evaluation information about the product corresponding to the search condition from the social network service, As a result (S640). That is, referring to FIG. 6F, the mobile terminal accesses a server providing a social network service to search for product information, a product review, and the like for a corresponding product, and provides the information to a user. In addition, the mobile terminal may generate a content for a product corresponding to the search condition (S810), and may transmit the generated content to the social network service (S820). That is, when the user has information to be shared, such as a price, a place, and a commodity price for the commodity, the mobile terminal can create it as content and provide it on a social network service as well as a message and an e-mail.

7 or 8, the product search method further includes a map generation step (S500) of generating a search map by displaying a search location according to the offline search result on a field map, (S510).

In step S500, the mobile terminal displays a product location corresponding to an offline search result on a field map to generate a search map. The on-site map can be stored in advance in the mobile terminal and can be provided in the field. The mobile terminal displays the location of the goods corresponding to the search condition on the field map, generates a search map, and displays the search map on the screen (S510). 5, the search map includes product information, current mobile terminal (user) location A1, travel path A2 of the mobile terminal (user), search completion (c) Information such as the retrieval state A3 during collection or the like is displayed individually or simultaneously. The mobile terminal may store the search result in the memory together with the search result (S700).

As described above, the mobile terminal and its product search method according to the present invention can perform close-range communication with products storing their own information, and can easily search a product of a user's desired condition in a non-contact manner at a certain distance . The mobile terminal can easily retrieve the goods of the desired condition offline while moving, in particular, by easily acquiring information from the products storing the own information by using the adjacent magnetic field communication. The mobile terminal searches for and presents the same goods online, simultaneously or sequentially, thereby making it possible for a user or the like to facilitate the purchase.
