DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method and an apparatus for evaluating the quality of a touch screen according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a flowchart illustrating a method for evaluating a touch screen quality according to the present invention, FIG. 2 is a flowchart illustrating a process for deriving a first formula among methods for assessing the quality of a touch screen according to the present invention, FIG. 5 is a flowchart illustrating a process for deriving a second formula among the methods of evaluating the quality of a touch screen according to the present invention.

As shown in FIGS. 1 and 2, in the method for evaluating the quality of a touch screen according to the present invention, first of all, emotional evaluation is performed on at least one emotional vocabulary expressing an emotional quality sense of the touch screen to form first data , A first equation related to the correlation between the emotional vocabulary and the emotional quality sense is calculated by statistical regression analysis of the first data (S100).

In the first formula calculation step S100, at least one emotional vocabulary expressing the emotional quality sense is extracted prior to calculating the first formula (S110).

The emotional quality sense can be auditory quality sense, olfactory sense quality, taste quality sense, visual quality sense and tactual quality sense based on human sense of five. In terms of touch screen, Quality can be appreciated.

The visual quality sense refers to the idea that human beings visually recognize the quality of the touch screen. That is, the visual quality sense refers to visually judging whether a human being has a high or low quality of a touch screen. Specifically, the visual quality sense may appear as a combination of a plurality of visual sensibility vocabulary expressing a visual quality sense.

The abstract sensibility felt by humans on the object, etc. can be described in detail using specific vocabulary, so that abstract visual quality sense can be analyzed concretely by extracting a combination of visual and emotional vocabularies that are specific vocabularies describing visual quality sense .

In one embodiment, the visual sensibility vocabulary includes a sense of flatness indicating the degree of the surface of the touch screen being uneven or rugged, a luminous intensity indicative of the brightness and darkness of the surface of the touch screen when the touch screen is off, May include a glossiness indicating the degree of reflection of light on the surface of the touch screen when the power of the touch screen is turned off.

Tactile quality sense refers to the notion that human beings recognize the quality of touch screen tactually. That is, the tactual quality sense refers to a tactual determination of whether a human being has a high or low quality of a touch screen using a finger or the like. Specifically, the tactual quality sense refers to a plurality of tactile sensibility vocabulary expressing a tactual sense of quality Combination.

Since the abstract emotion felt by human beings can be described with specific vocabulary, the combination of tactile and emotional vocabularies, which are specific vocabularies describing the tactual quality sense, can be used to analyze the abstract tactual sense of quality .

In one embodiment, such tactile sensibility vocabulary may be used to determine whether the touch screen surface is gritty or smooth, i.e., a rough sense of degree of friction on the surface of the touch screen, And a stiffness indicating the degree of hardness of the surface of the screen.

Although the concrete vocabulary has been described as an example of the visual sensibility vocabulary and the tactual sensibility vocabulary in the above description, the present invention is not necessarily limited thereto, but the present invention is not necessarily limited thereto, and may be applied to other vocabulary expressing synonyms, synonyms, Lt; / RTI >

Next, the emotional quality sense is evaluated using the plurality of emotional vocabularies to form first data (S120).

The sense of quality perceived by human beings can be materialized through emotional vocabulary, but it is necessary to objectify it because subjective evaluation can intervene. Therefore, it is possible to quantitatively measure emotional quality sense perceived by humans by physically or chemically measuring the physicochemical elements corresponding to one-to-one or one-to-many sentences in the emotional vocabulary.

Therefore, physicochemical factors are elements that can correspond to emotional vocabulary and can be measured by physical or chemical measurement methods. Physical-chemical factors are visual physical chemical elements corresponding to visual sensibility vocabulary, and tactile physics corresponding to tactile sensibility vocabulary.

In one embodiment, the visual physical chemical element corresponding to the flatness is flatness, the visual physical chemical element corresponding to the lightness indicator is lightness, the visual physical chemical element corresponding to the gloss is reflectance, The tactile physical chemical element corresponding to the sense is the surface roughness and the friction coefficient, and the tactile physical chemical element corresponding to the sense of rigidity may be absolute hardness.

Next, the second data is formed by measuring physically or chemically evaluable physical chemical elements corresponding to the emotional vocabulary (S220).

The second data is formed by measuring the above-described physical chemical elements using various measuring equipment and using them.

In one embodiment, the visual physical tactile element and the tactual physical chemical element can be measured by the following method, but are not limited thereto.

Next, the second data is statistically regression-analyzed to calculate a second equation related to the correlation between the emotional vocabulary and the physical chemical element (S230).

The second equation is a formula for calculating the weight of the physical chemical elements based on the second data, which is the measurement value of the physical chemical element constituting the emotional vocabulary. The concrete expression is as follows.

,

,

Here, e, f, h, and i are constants, b is a visual sensibility vocabulary, d is a tactile sensibility vocabulary, g is a visual physical chemical element, and j is a tactile physical chemical element.

In one embodiment, the second equation may be expressed as: < RTI ID = 0.0 >

That is, the flatness, which is one of the visual sensibility vocabulary, can be expressed in the form of a linear function combining the constants of e and f with the measured values of the flatness, which is the starting physical chemical element, and one of the tactile sensibility vocabulary, It can be expressed as a combination of a surface roughness and a friction coefficient, which are tactile physical chemical elements, as constants.

Next, as shown in FIG. 1, the second equation is substituted into the first equation to calculate a third equation relating to the correlation between the physical chemical element and the emotional quality sense (S300).

The third equation is defined as a formula of emotional quality sense composed of only physical chemical elements and constants by substituting the second equation about the correlation between the emotional vocabulary and the physical chemical element into the first equation.

Here, A, B, a, c, e, f, h, and i are constants, g is a visual physical chemical element, and j is a tactile physical chemical element.

The third formula is composed of physicochemical elements that can be objectively measured, except subjective sensibility vocabulary, so that the sensibility can be objectively evaluated.

Next, the emotional quality sense of the touch screen for measuring the quality is predicted using the third equation (S400).

The sensory quality of the touch screen can be predicted by using the third equation after measuring the physicochemical elements of the touch screen to measure the quality.

As the emotional quality sense of the product can be objectively evaluated and predicted using the third formula, the development time and cost can be reduced by utilizing the predicted emotional quality sense in the research and development.
