The pressure information may be a value of contact resistance that changes according to the amount of pressure applied by the sensor 210, a current value and a voltage value according to the change of the contact resistance, and mean information used to calculate the weight of an object. do. The unit of the pressure information may be expressed in kΩ, mA, Voltage, and the like. Here, the contact resistance refers to the electrical resistance generated between when the electricity flows through the contact surface of the two objects, the value is characterized in that it depends on the type of conductor, pressure, current density.

The contact surface information refers to information used to identify an object, including at least one of the shape of the contact surface, the area of the contact surface, and the number of contact regions. In the present specification, the contact area may be a face, a line, or a point.

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, identification information refers to feature information that can distinguish an object. In other words, the identification information refers to 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 regions. The identification information may be configured by combining at least one or one or more of the shape of the contact surface, the area of the contact surface, and the number of contact regions, and it will be understood by those skilled in the art. For example, when the object is a container to which an electronic tag is attached, the electronic tag information attached to the container obtained through the electronic tag reader of the electronic device may be used as identification information of the container. In addition, when the electronic device has a camera, an image of an object photographed by the camera may be used as identification information, but is not limited thereto.

Here, the external device may be a server or a device (eg, a TV, a computer, a notebook, a PDA, etc.) in which the user can check the guide information. In addition, the server may be a server that manages information associated with the object.

The display 230 outputs a predetermined screen and allows the user of the electronic apparatus 1000 to visually recognize the predetermined image or information. The display 230 may output a predetermined screen under the control of the processor 220. The display 230 may include a display 230 panel and may output a screen for guide information on the display 230 panel. In addition, the display 230 may include a touch screen, and may receive an external input (for example, 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 weight change amount based on a time point at which the weight is measured, a measured weight, and a weight difference measured at two consecutive time points. For example, when the object is a container, the weight information may be intake information of the contents of the container calculated from the time point at which the container is measured, the weight of the container, and the weight difference of the container measured at two consecutive time points.

The processor 220 obtains guide information about the object based on the weight and the identification information. The display 230 outputs guide information. In the present specification, the guide information refers to information provided to induce a user's action related to identification information and weight information of the object. The guide information may be feeding guide information or weight guide information, depending on the type of object. When the object is an object such as a container, the guide information may be feeding guide information, and the feeding guide information may be one of feeding guide information, moisture intake guide information, and eating habit guide information, depending on the type of container. It is not limited. In addition, when the object is a human, guide information may be weight guide information.

In addition, the weight guide information means information provided to induce user actions 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 a pressure applied to the display 230 by the object and obtain pressure information. The sensor 210 may be mounted on a layer different from the layer displaying the screen provided by the display 230. The sensor 210 may be a pressure sensor made of a transparent thin film material, but is not limited thereto.

The sensor 210 may sense a contact resistance that varies with 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 a weight corresponding to the value of the contact resistance.

As a specific example, when the object is a container, it is assumed that liquid is contained in the container. The sensor 210 obtains pressure information by sensing a pressure applied to the display 230 by a container placed on the display 230. Here, the weight measurement of the container at the “specific time point” may refer to the weight detected through the weight measurement of the container regardless of the number of times within a predetermined time based on a specific time point in order to accurately measure the weight of the container. For example, the weight of the container at the first time point can be obtained based on the pressure sensed for a predetermined time (eg, 3 seconds) assuming that there is substantially no change in the weight of the contents contained in the container. For example, in the case of sensing the pressure five times in three seconds, the sensor 210 may calculate the average value of five times as the pressure value applied by the container to the display 230, and the median value of the five pressure values is determined by the container. The pressure value applied to the display 230 may be calculated or the pressure value may be calculated by a predetermined calculation method.

The sensor 210 may sense the pressure applied to the display 230 by the object at a plurality of time points, and the processor 220 may calculate the weight of the object based on the pressure information of the sensed pressure. In more detail, the sensor 210 senses a first pressure corresponding to the first time point and a 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 obtains guide information based on a difference between the first weight and the second weight, the first time point, and the second time point. For example, if the object is a container, the processor 220 determines the intake amount of the contents contained in the container from the difference between the first weight and the second weight. In addition, when the object is a person, the 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, the eating guide information is the intake of the contents based on the difference between the first weight and the second weight, the time of the intake of the contents Information (e.g. the time you took the contents), time information about the intake of the contents (e.g. time taken to consume the contents), next recommended intake information about the contents (e.g. Information, such as information to consume the contents). When the object is a human, the guide information may be weight guide information, and the weight guide information may include visual information about a weight change amount and a weight change amount based on the difference between the first weight and the second weight (eg, weight loss). Time measured), time information about how much weight has changed (e.g., how long it takes to lose weight), and attainment of your target weight (e.g. the approximate amount of weight based on the difference between your current weight and your target weight) At least one of the. The display 230 outputs the guide information.

The display 230 may output guide information by distinguishing between a case where an object is placed on the display 230 and a case where the object is removed. When the object is placed on the display 230, the display 230 may output the guide information to a partial region of the entire region for outputting the screen of the display 230 except for the region where the container is placed. On the other hand, when the object is removed from the display 230, the display 230 may output the guide information to an area in which an area is extended. For example, the display 230 may output the guide information to the entire area.

6 is a flowchart illustrating a flow of a principle of measuring the weight of an object, according to an exemplary embodiment.

Sensors mounted on the electronic device measure the pressure that the object exerts on the display. In addition, 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 sensor that converts a physical quantity such as force or load into an electrical signal to measure force or load. The object is deformed proportionally by force or load, and the amount of deformation per unit length is called strain. In this case, the generated strain may have a feature that varies linearly with the magnitude of the force or load. The sensor measuring the strain may be a strain gauge. The load cell converts the physical deformation generated at the receiving part of the elastic deformation body that generates structurally stable deformation with respect to force or load into electrical resistance change by using a strain gauge, and configures a Wheatstone Bridge electric circuit to convert it into a precise electrical signal. The principle can be used.

On the other hand, it can be understood by those skilled in the art that the weight of the object can be measured by using a sensor using other principles in addition to measuring the weight of the object using the load cell principle.

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

In relation to the principle of the load cell, the relationship between the stress and the strain generated in the material under compression can be represented by the following equations (1) and (2).

Equation 1

Equation 2

In operation S620, as the elastic material is deformed, the strain gauge detects a resistance change, and the resistance change amount of the strain gauge may be converted into a value of the voltage change amount by the Wheatstone bridge.

Resistance in the material is proportional to the length of the material and inversely proportional to the cross-sectional area. Equation 3 can be used because the relationship between the strain gauge's resistance change and strain is linear in a typical material.

Equation 3

Where R is the resistance value of the strain gage, ΔR is the resistance change of the strain gage, K is the gage factor of the strain gage, ε is the strain STRAIN, sigma is the stress STRESS, and E is the elastic modulus of the object.

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

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

Strain gages are resistance sensors that measure the amount of deformation of an object by converting a physical strain into an electrical signal.

Explaining the basic principle of a strain gauge, when the metal resistor is pulled, it becomes longer and thinner, and the electrical resistance value increases. Specifically, when the resistor is attached to the object to be measured to relax and shrink in the longitudinal direction, a change in resistance occurs in proportion to the deformation amount. In particular, the thinner and thinner the resistor is, the more it will move with the object under test.

In addition, in the absence of pressure, the sensor has an infinite resistance value. Here, a little force or weight may cause 100 kΩ resistance. The higher the force or weight, the lower the resistance. A related graph is shown in FIG.

Referring to FIG. 10, the horizontal axis represents a weight value g and the vertical axis represents a resistance value kΩ. As shown in Figure 10, the pressure sensor tends to increase the corresponding weight value as the measured resistance value decreases, Figure 10 is an example, in the technical field to which this embodiment belongs may have a different value Anyone with ordinary knowledge can understand.
