According to one embodiment, the electronic device 1000 may include a sensor 210, a processor 220, and a display 230. The electronic device 1000 can be implemented by more components than the components shown in Fig. 2, and the electronic device 1000 can be implemented by fewer components. Hereinafter, the components will be described in order.

The sensor 210 senses the pressure exerted from the object placed on the display 230 and senses the contact surface of the object with the display 230. Here, the sensor 210 may include a first sensor for sensing the pressure and the contact surface, a first sensor for sensing the pressure, and a second sensor for sensing the contact surface. Specifically, for example, the first sensor may be a pressure sensor, and the second sensor may be implemented by a touch sensor, but the present invention is not limited thereto. In this specification, the pressure sensor may be an electrical pressure sensor such as a strain gauge, a capacitive, a piezoelectric, an inductance type, a semiconductor type FSR (Force Sensitive Resistor), and the touch sensor may be a contact- Capacitive overlay, Registive Overlay, Infrared Beam, Integral Strain Guage, Surface Acoustic Wave, Piezo effect method, piezo Electric, and a force touch sensor. However, the present invention is not limited thereto.

Sensor 210 acquires pressure information from the sensed pressure and acquires contact surface information from the sensed contact surface. The pressure information may be a value of a contact resistance varying with a magnitude of a pressure applied by the sensor 210, a current value and a voltage value according to a change in contact resistance, and may be information used to calculate an object weight do. The units of pressure information can be expressed in kΩ, mA, voltage, and so on. Here, the contact resistance means an electrical resistance generated when electricity flows through the contact surfaces of two objects, and the value is dependent on the kind of conductor, pressure, current density, and the like.

The contact surface information includes at least one of the shape of the contact surface, the area of the contact surface, and the number of contact areas, and means information used to identify the object. As used herein, the contact area may be a face, a line, or a dot.

The processor 220 calculates the weight of the object according to the pressure information received from the sensor 210 and determines the identification information of the object according to the contact surface information received from the sensor 210. In the present specification, the identification information means characteristic information capable of distinguishing objects. That is, the identification information means information used to distinguish the first object from the second object. For example, the contact surface information may include at least one of the shape of the contact surface, the area of the contact surface, and the number of contact areas. The identification information may be formed by combining at least one or more than one of the shape of the contact surface, the area of the contact surface, and the number of contact areas, but is not limited thereto. For example, when the object is a container to which an electronic tag is attached, electronic tag information attached to the container obtained through the electronic tag reader of the electronic device can be used as identification information of the container. Further, when the electronic device has a camera, the image of the object photographed by the camera can be used as the identification information, but is not limited thereto.

The processor 220 identifies the object by comparing the determined identification information with the identification information of the pre-stored object. The processor 220 obtains the guide information for the object based on the weight and the identification information. The processor 220 controls the display 230 to output guide information. In addition, the processor 220 controls the guide information to be outputted as a voice through a speaker (not shown) of the electronic device 1000. In addition, the processor 220 may control to transmit guide information to an external device (not shown). Here, the external device may be a server or a device (e.g., a TV, a computer, a notebook, a PDA, or the like) that can confirm the guide information by the user. In addition, the server may be a server that manages information related to the object.

The display 230 outputs a predetermined screen and allows a user of the electronic device 1000 to visually recognize a predetermined image or information. The display 230 may output a predetermined screen according to the control of the processor 220. [ The display 230 includes a display panel 230, and can display a screen or the like for guide information on the display panel 230. The display 230 also includes a touch screen and can receive an external input (e.g., an input received from a user) and display an output corresponding to the external input.

The processor 220 obtains weight information based on the weight of the object. The weight information may include a point at which the weight is measured, a measured weight, a weight variation based on the weight difference measured at two consecutive points in time, and the like. For example, when the object is a container, the weight information may be information on the amount of intake of the contents of the container calculated from the time at which the container was measured, the weight of the container, and the weight difference of the container measured at two consecutive points in time.

The processor 220 obtains the guide information for the object based on the weight and the identification information. The display 230 outputs the guide information. In this specification, the guide information means information provided to induce the user's actions related to the identification information and the weight information of the object. The guide information may be eating guide information or weight guide information, depending on the type of object. If the object is an object such as a container, the guide information may be eating guide information, and the eating guide information may be one of feeding guide information, moisture intake guide information, and eating habit guide information depending on the type of container. But is not limited thereto. Also, if the object is a person, the guide information may be weight guide information.

Herein, the eating guide information means information provided for inducing a user action related to a user's intake amount through an object such as a container. In addition, the feeding guide information means information provided to induce a user action related to the amount of feeding provided to the infant through the bottle. In addition, the water intake guide information refers to information provided to induce a user action related to the amount of water to drink through things such as a user's water bottle or a mug. In addition, the eating guide information refers to information provided to induce a user action related to a food amount consumed through an object such as a user's dish or bowl.

In addition, the weight guide information means information provided to induce a user action related to the weight of the user.

The sensor 210 may be mounted on the front surface of the electronic device 1000. The sensor 210 may sense the pressure the object applies to the display 230 and obtain pressure information. The sensor 210 may be mounted on a layer different from a layer for displaying a screen provided on the display 230. The sensor 210 may be a pressure sensor of a transparent thin film material and is not limited thereto.

The sensor 210 can sense the contact resistance which changes according to the pressure. The sensor 210 may sense the value of the contact resistance when the object is placed on the display 230 and the processor 220 may calculate the weight corresponding to the value of the contact resistance.

As a specific example, if the object is a container, it is assumed that the container contains liquid. The sensor 210 senses the pressure applied by the container placed on the display 230 to the display 230 to obtain pressure information. Here, the weight of the container at the "specific time point" may mean the weight detected through the weight measurement of the container regardless of the number of times within a predetermined time based on the specific time point to accurately measure the weight of the container. For example, the weight of the container at the first time point may be obtained based on the sensed pressure for a predetermined time (e.g., 3 seconds), on the assumption that there is substantially no change in the weight of the contents contained in the container. For example, if the pressure is sensed five times for three seconds, the sensor 210 may calculate the average value five times as the pressure value that the container applies to the display 230, The pressure value to be applied to the display 230 may be calculated, or the pressure value may be calculated by a predetermined calculation method.

The sensor 210 senses the pressure applied by the object to the display 230 at a plurality of points in time, and the processor 220 can calculate the weight of the object based on the pressure information of the sensed pressure. More specifically, the sensor 210 senses the first pressure corresponding to the first time point and the second pressure corresponding to the second time point. The processor 220 calculates a first weight corresponding to the first pressure and a second weight corresponding to the second pressure. The processor 220 acquires the guide information based on the difference between the first weight and the second weight, the first point of time and the second point of time. For example, if the object is a container, the processor 220 determines the amount of content contained in the container from the difference between the first weight and the second weight. Further, when the object is a person, the body weight change amount of the person is determined from the difference between the first weight and the second weight. Specifically, when the object is a container, the guide information may be the eating guide information, and the eating guide information may include information on an amount of intake of the contents based on the difference between the first weight and the second weight, Time information on the amount of intake of the contents (for example, the time taken to ingest the contents), information on the next recommended amount of intake for the contents (for example, how many hours after Information to consume the contents, and the like). If the object is a person, the guide information may be weight guide information, and the weight guide information may include weight change amount based on a difference between the first weight and the second weight, time information on a weight change amount (e.g., (For example, the time required for weight reduction), the target weight achievement (for example, the approximate degree of the weight value according to the difference between the target weight to be obtained by the user and the current weight) Or the like. The display 230 outputs the guide information.

The display 230 can output the guide information by distinguishing the case where the object is placed on the display 230 and the case where it is removed. When the object is placed on the display 230, the display 230 can output the guide information to a partial area of the area excluding the area where the container is laid out of the entire area for outputting the screen of the display 230. [ On the other hand, if the object is removed on the display 230, the display 230 may output the guide information to an area extending a part of the area. For example, the display 230 can output guide information to the entire area of the screen.

The electronic device 1000 may further include a memory (not shown). The memory may store the identification information of the object, the weight information of the object, and the guide information according to the identification information of the object as the history information based on the time when the pressure is sensed. When the sensor 210 senses a third pressure that is different from the pressure, the processor 220 calculates a third weight of the object corresponding to the third pressure, and displays guide information based on the third weight and history information (230). For example, in the case where the object is a bottle, the history information includes an average of one lactation intake amount information, and the third weight is the infant's current lactation intake, in relation to the infant's lactation intake.

6 is a flow diagram illustrating a flow of principles for measuring an object's weight, in accordance with one embodiment.

A sensor mounted on an electronic device measures the pressure exerted by the object on the display. Further, the electronic device calculates the weight based on the measured pressure. A load cell may be used for the sensor.

A load cell is a load-sensing transducer that measures force or load by converting physical quantities such as force or load into electrical signals. An object is deformed in proportion to a force or a load, and a strain per unit length is called a strain. In this case, the generated strain may have a characteristic that changes linearly with the magnitude of the force or the load. The strain measuring sensor may be a strain gauge. The load cell transforms the physical deformation that occurs in the retaining part of the elastic deformable body which generates structurally stable deformation against the force or the load into the change of the electrical resistance by using the strain gauge and converts it into a precise electrical signal Principle can be used.

As shown in Fig. 6, in step S610, the material having an elastic force by an external force is deformed.

With respect to the principle of the load cell, the relationship between the stress and the strain occurring in the material under compression can be expressed by the following equations (1) and (2).

In step S620, as the elastic material is deformed, the strain gauge senses the resistance change, and the resistance change amount of the strain gauge can be converted into the value of the voltage change amount by the Wheatstone bridge.

The resistance generated in the material is proportional to the length of the material and in inverse proportion to the cross-sectional area. Since the relationship between the resistance change of the strain gage and strain is expressed linearly in a general material, equation (3) can be used.

Where R is the resistance value of the strain gage, ΔR is the resistance change of the strain gage, K is the strain gage factor of the strain gage, ε is the strain (STRAIN), σ is the stress (STRESS) and E is the modulus of elasticity of the object.

In step S630, the signal including the voltage change amount is amplified through an electric circuit, and A / D conversion is performed.

In step S640, the converted value is output as data.
