1 is a flow diagram illustrating a method for determining emotions of a computer in accordance with one embodiment.

Each step shown in Fig. 1 consists of steps that are processed in a time-series manner in a computer. In this specification, a computer is used as a concept including a computing device including at least one processor, and may include a smart phone, a tablet PC, a notebook, a desktop, a server, a robot, and an IOT device.

In step S110, the computer maps the plurality of emotions to the respective different coordinates in the plane including the first axis and the second axis.

In one embodiment, the first axis corresponds to Pleasure and the second axis corresponds to Dominance.

The computer determines representative values of a plurality of emotions in a pleasure-dominance (P-D) plane including a first axis and a second axis, and maps each determined representative value to a P-D plane.

For example, the computer maps representative values of a total of eight emotions to each coordinate of the P-D plane. In this case, the computer has nine emotional states including base emotions in addition to eight emotions.

For example, the eight emotional states are respectively Fear, Surprise, Sadness, Disgust, Anger, Anticipation, Joy, and Acceptance. But is not limited thereto.

In step S120, the computer divides the P-D plane based on the plurality of mapped coordinates in step S110.

For example, the computer can divide the P-D plane using a Voronoi diagram based on the coordinates representing the eight emotions.

Referring to FIG. 2, a PD plane 200 including a first axis 1 and a second axis 2 is divided into a plurality of regions (or regions) by using a Voronoi diagram based on eight coordinates (10 to 80) 210 to 280) are shown.

As shown in Fig. 2, the coordinates representing each of the plurality of emotions may be located anywhere on the P-D plane. However, for the sake of convenience of explanation, the case where the coordinates (10 to 80) are uniformly arranged on the PD plane 300 as shown in FIG. 3 and the plurality of regions 310 to 380 are also uniformly divided .

In Fig. 3, each of the divided regions 310 to 380 corresponds to the emotions indicated by the coordinates (10 to 80) included in each region.

In step S130, the computer creates a plurality of horns having a height in a third axial direction perpendicular to the P-D plane, with each of the divided planes being the bottom in step S120.

In one embodiment, the third axis corresponds to the Arousal, and the first axis, the second axis and the third axis constitute the PAD emotion space consisting of the P-D plane and the A axis perpendicular to the P-D plane.

Referring to FIG. 4, an emotional space 400 is shown comprising a first axis 1, a second axis 2, and a third axis 3.

In the emotion space 400 shown in FIG. 4, each of the plurality of regions 310 to 380 shown in FIG. 3 is a bottom surface, and the heights 410 to 480 having a height in the third axis 3 direction .

In the emotion space 400 shown in Fig. 4, the coordinates included in each of the plurality of horns 410 to 480 are the coordinates (10 to 80) included in the bottoms 310 to 380 of each of the plurality of horns 410 to 480 ). ≪ / RTI > In addition, the magnitude of the third axis 3 direction component of each of the coordinates included in each of the plurality of horns 410 to 480 is greater than the magnitude of each of the coordinates 10 to 80 included in each of the plurality of horns 410 to 480 It is proportional to the depth of the corresponding emotion.

For example, referring to FIG. 4, the horn 440 is divided into three regions 442, 444, and 446 along the third axis 3 height. The depth of emotion may be proportional to the height, or may be divided into a plurality of areas as shown in FIG. 4, and may be configured to be deepened by one step for each of the divided areas. For example, in the emotion shown by the horn 440 in FIG. 4, the coordinates contained in the area 442 represent the emotional depth immediately following the base emotion, and the coordinates contained in the area 444 are in the area 442 The coordinates contained in the area 446 represent emotions one step deeper than the coordinates contained in the area 444. [

In one embodiment, the coordinates in the emotion space 400 where the third axis component is less than or equal to zero correspond to the base emotion.

In step S140, the computer determines a first coordinate 500 included in the three-dimensional emotion space 400 composed of the first axis 1, the second axis 2, and the third axis 3.

In one embodiment, the first coordinate 500 is used to determine the current emotional state of the computer.

In step S150, the computer determines the emotion corresponding to the first coordinate (500).

In one embodiment, the computer maps the first coordinate 500 to the second coordinate on the polar coordinate emotional plane.

Referring to FIG. 5, a polar emotional plane 600 is shown. The computer maps the first coordinate (500) to the second coordinate (510) on the polar coordinate emotion plane (600).

In one embodiment, the computer uses the first axis (1) component and the second axis (2) component of the first coordinate (500) to calculate the angle (?) Of the second coordinate (510).

The computer also calculates the radius r of the second coordinate 510 using the third axis 3 component of the first coordinate 500.

The computer determines the emotion corresponding to the second coordinate 510.

In one embodiment, the coordinates on the polar emotional plane 600 correspond to points on the emotion wheel, respectively.

For example, the coordinates on the polar emotional plane 600 correspond to points on the Plutchik's Wheel of Emotions 700 shown in FIG. 6, respectively.

7, an example in which the polar coordinate emotion plane 600 is mapped onto the emotional wheel 700 of the fluency is shown. According to FIG. 7, the second coordinate 510 corresponds to 'trust'.

The emotion determined according to the disclosed embodiment is utilized to determine the emotional state of the artificial intelligence computer or robot. The feelings of an artificial intelligence computer or robot continuously change according to internal factors and external factors.

For example, as an internal factor, the arousal value of a particular emotional state decreases over time. If a person does not have a special case, the emotional state becomes calm. Likewise, the emotional state according to the disclosed embodiment leads to a decrease in the arousal value over time without a special event.

In one embodiment, the higher the arousal value, the faster the drop.

External factors may include, but are not limited to, conversations between a computer or a robot and a user, battery status, presence or absence of a charger connection, and activity time.

The method for changing the emotional state of the computer is performed by at least one of the following embodiments 1 and 2. [

[Example 1]

The computer obtains the variation of each of the first axis component 1, the second axis component 2, and the third axis component 3 with respect to the first coordinate 500. The amount of change of each of the components of the first axis 1, the second axis 2 and the third axis 3 is determined by the first axis 1, the second axis 2 and the third axis 3, Changes in emotional components.

The computer applies the obtained amount of change to the first coordinate (500) to calculate the third coordinate. The third coordinate represents the changed emotion of the computer.

Thus, the computer changes the emotion of the computer to the emotion corresponding to the calculated third coordinate.

[Example 2]

The computer acquires a fourth coordinate corresponding to the target emotion of the computer. That is, unlike obtaining the change amount of emotion in the first embodiment, in the second embodiment, the coordinates of the target emotion are obtained immediately.

Referring to Fig. 8, an example of the emotion changing method according to the second embodiment is shown.

In Figure 8, it is assumed that the first coordinate 800 representative of the current emotional state of the computer is located in region 442 of the horn 440.

The computer acquires a fourth coordinate 810 corresponding to the target emotion. For example, since the fourth coordinate 810 is located in an area 446 higher than the area 442, the computer belongs to the same category as the present, but the fourth coordinate 810 is selected to express a deeper emotion. .

The emotion state of the computer moves from the first coordinate 800 to the fourth coordinate 810 at a predetermined speed. The predetermined rate may be fixed to a specific constant, or may be set differently depending on the case, as the rate at which the emotion of the computer changes.

In one embodiment, the emotional state of the computer may immediately move from the first coordinate 800 to the fourth coordinate 810 without a separate intermediate step. For example, if the predetermined speed is set to infinity or a sufficiently large number, the emotional change of the computer may occur instantaneously (instantly).

By moving the coordinates indicating the emotional state from the first coordinate 800 to the fourth coordinate 810 at a predetermined rate, the computer can express a gradual change in emotion.

In one embodiment, the computer obtains an emotion corresponding to each coordinate on the path that moves from the first coordinate 800 to the fourth coordinate 810, and changes the emotion of the computer with the obtained emotion.

For example, the computer may step-wise or continuously represent gradually increasing emotions along a path that moves from the first coordinate 800 to the fourth coordinate 810.

In one embodiment, the emotional state of the computer may change to a new emotional state again while changing. For example, in an increasingly anger-raising situation, it may change to a pleasant mood by a specific event.

Referring to FIG. 8, the emotional state of the computer is shifting from the first coordinate 800 to the second coordinate 810.

At this time, the computer can change the target emotion of the computer to the fifth coordinate 830.

At this time, the computer moves from the coordinate 820 at the moment when the target emotion is changed to the fifth coordinate 830, which is the target emotion, at a predetermined speed.

Similarly, the computer obtains emotion corresponding to each coordinate on the path that moves from coordinate 820 to fifth coordinate 830, and changes the emotion of the computer with the obtained emotion.

However, in the movement process or in the process of selecting arbitrary coordinates, coordinates not belonging to any horn can be selected.

Referring to FIG. 9, coordinates 900 that do not belong to any horn are shown. If the coordinate 900 indicating the emotional state of the computer does not belong to any horn, the computer moves the coordinate 900 vertically to the horn 440 closest to the coordinate 900.

For example, the computer draws a perpendicular perpendicular to one side of the horn 400 from the coordinates 900, and uses the coordinates 910 corresponding to the feet of the waterline as coordinates indicating the emotional state of the computer.

The computer can interact with the user by expressing the determined emotions.

For example, the computer analyzes voice differences according to a human emotion state, and generates voice data for emotion states corresponding to the emotion wheels 700 shown in FIG. The computer can modulate the voice of the computer with a voice corresponding to the determined emotion of the computer.

For example, a computer can control pitch, volume (dB), and speech rate of speech.

Further, in the case of an artificial intelligent robot type computer, each component corresponding to the body can be provided. For example, an artificial intelligence robot may have a heart-shaped component for displaying an emotional state.

The artificial intelligence robot can display the color corresponding to the determined emotion state with the color of the heart.

Also, it is possible to reproduce the heartbeat according to the emotion state through the vibration.

According to the disclosed embodiments, the various emotion states and the depths of the emotion states can be expressed concretely. Also, the emotion changes gradually as the actual person, and can be changed naturally even in the emotion change process , It is possible to express the emotion of the computer more naturally.
