Figure 4 is a diagram for explaining the principle of a 3D hologram audiobook device according to an embodiment of the present invention.

Physically, a hologram is a method of creating a three-dimensional image using the wavelength and angle of light. Unlike general images, this is the principle of forming an image using light interference using laser light of a certain size. At this time, the laser light used to form the image has a specific wavelength and brightness that is distinct from other lights, and this can be used to create a 3D image.

Referring to FIGS. 3 and 4 , the 3D hologram audiobook device 120 may be configured to include at least one image display means and a tetrahedral-shaped reflector.

Here, the individual plates constituting the tetrahedral reflector are in a kind of pyramid shape and may be made of OHP film.

First, the four images up, down, left, and right may be images taken at angles rotated by 90 degrees. When this is reflected on a pyramid-shaped reflector made of OHP film, a tetrahedral-shaped structure is formed inside the reflector, and each side of this structure can reflect images up, down, left, and right, respectively. The OHP film used at this time, unlike general reflectors, can be designed to reflect light in a special way to create a 3D hologram effect.

Therefore, the image reflected through the OHP film has different positions and sizes depending on the wavelength and angle of the light, and combining them can create a 3D hologram effect.

By using this pyramid reflector to reflect four images, up, down, left, and right, and placing them in appropriate positions, the user can view a 3D image in the form of a hologram. In one embodiment, the user can shine light directly on the pyramid reflector or provide light to the pyramid reflector through an image display means provided together, and appropriately adjust the position, size, brightness, etc. of the reflector and the image. The best hologram effect can be achieved.

FIG. 5 is a block diagram briefly showing the internal configuration of a content providing server according to an embodiment of the present invention, and FIG. 6 is a diagram showing a change in the size of a hologram image according to an emotional word according to an embodiment of the present invention.

The content providing server according to an embodiment of the present invention includes a book data database unit 131, an image data database unit 132, an audio data database unit 133, a text parsing unit 134, and an emotion dictionary storage unit 135. , a communication unit 136, and a control unit 137.

The book data database unit 131 stores book data for providing audiobooks. Here, the book data includes the title of the book, information about the author and translator, publisher information, table of contents, and information about the main text.

The image data database unit 132 stores image content, which is a visual image corresponding to each book data stored in the book data database unit 131.

The audio data database unit 133 stores voice data for each book data stored in the book data database unit 131.

The audio data database unit 133 receives and stores audio input for book data. The audio data database unit 133 receives and stores audio information provided by the audio provider.

Here, the person providing the voice may be a professional voice actor who reads the book data, or if the book is a foreign language book, a native speaker who speaks the foreign language natively may provide the voice for the book data. To provide voice, a voice provider, such as a native speaker, professional voice actor, or book reading expert, reads the content of the book data through a separately prepared microphone, and the voice reading the content can be input and processed. Voices for book data are separately stored in the audio data database unit 133.

The text parsing unit 134 receives book data from the book data database unit 131, separates each sentence from the text of the input book data, and performs morpheme analysis and phrase structure analysis on each sentence. Thus, each sentence can be divided into morpheme units. Here, the text parsing unit 134 may use a morpheme analyzer or a phrase structure phaser of known technology for morpheme analysis and phrase structure analysis.

The emotion dictionary storage unit 135 matches and stores the emotional category of a word representing a person's emotion and the emotional expression of the corresponding emotional category.

For example, the emotion category of joy is lovely. There are emotional expressions such as excited and happy, the emotional category of sadness includes emotional expressions such as sad, painful, and mournful, and the emotional category of fear includes emotional expressions such as fearful, anxious, and anxious. , the emotional category of anger can include emotional expressions such as enraged, indignant, and shocked.

The emotion dictionary storage unit 135 classifies and registers emotion words that represent human emotions, and these emotion words can be used to find emotional expressions of words recognized by the text parsing unit 134.

When receiving a content request signal from the hologram audiobook device 120 through the communication unit 136, the control unit 137 extracts content included in the received content request signal.

The control unit 137 extracts book data corresponding to the extracted content in conjunction with the book data database unit 131, divides the extracted book data into morpheme units by the text parsing unit 134, and the emotion dictionary storage unit ( 135), it is possible to analyze whether the segmented morpheme belongs to an emotional word.

In other words, the control unit 137 may determine that a segmented morpheme is an emotion word if it matches the emotion category of a word representing a person's emotion and the emotional expression of the corresponding emotion category.

The control unit 137 extracts book data, image content, and voice data corresponding to the extracted content in conjunction with the book data database unit 131, the image data database unit 132, and the audio data database unit 133.

Image content refers to hologram content output as a 3D hologram from the hologram audiobook device 120.

Accordingly, the control unit 137 converts the image content into hologram content suitable for the hologram form to be used in the 3D hologram format.

The control unit 137, in conjunction with the emotion dictionary storage unit 135, determines whether the word included in the book data is an emotion word that matches the emotion category of a word representing a person's emotion and the emotion expression of the corresponding emotion category, and determines whether the word contained in the book data matches the emotion expression of the emotion category. Extract the preset hologram image size and voice size corresponding to .

As shown in FIG. 6, the control unit 137 can configure the holographic image size and voice size differently depending on the emotional word.

For example, the hologram image size and voice volume are assumed to be 10 as the maximum, and if the emotion word is an emotional category and emotional expression related to sadness based on 10, the hologram image size is set to 3 and the voice volume is set to 2. For emotional categories and emotional expressions related to joy, set the hologram image size to 6 and voice level to 6, and for emotional categories and emotional expressions related to fear, set the holographic image size to 9 and voice level to 9, etc. You can set it to image size and audio size.

A specific first method of setting the hologram image size and voice size will be described as follows.

The control unit 137 extracts book data corresponding to the extracted content in conjunction with the book data database unit 131, divides the extracted book data into morpheme units by the text parsing unit 134, and the emotion dictionary storage unit ( 135), it is determined whether the segmented morpheme belongs to an emotional word.

The emotion dictionary storage unit 135 stores the emotion type according to the emotion word, the emotion components belonging to the emotion type, and the emotion composition ratio of the emotion components.

If the morpheme divided by the emotion dictionary storage unit 135 is an emotion word, the control unit 137 determines the emotion type of the emotion word and detects the emotion components and emotion composition ratio belonging to the emotion type.

Emotion types include, but are not limited to, sadness, joy, fear, routine, and complaints, and may include various types of emotions.

An emotion type includes multiple emotional components, and each emotional component can have a different emotional composition ratio.

The emotional type of sadness includes emotional components of denial, anger, bargaining, depression, and acceptance.

The emotional type of joy includes the emotional components of gratitude, gratitude, happiness, excitement, and satisfaction.

The emotional type of fear includes the emotional components of compulsion, worry, fear, anxiety, and obsession.

Everyday emotion types include the emotion components of boredom, tiredness, calmness, and surprise.

The emotional type of complaint is surprise. It includes emotional components of insult, betrayal, irritation, and frustration.

For example, the control unit 137 uses the emotion dictionary storage unit 135 to determine that if the text of the book data is “I am depressed,” it belongs to the emotion type of sadness and uses the emotion word of depression to determine 100%. As a standard, the emotional composition ratio of 0% denial, 0% anger, 0% compromise, 100% depression, and 0% acceptance is extracted.

The control unit 137 uses the emotion dictionary storage unit 135 to determine that if the text of the book data is “I want to die,” it belongs to the emotion type of sadness and uses the emotion word of death to determine negation 50 based on 100%. %, anger 5%, compromise 0%, depression 45%, acceptance 0%.

In other words, even if the text in the book data is of the same emotion type of sadness, the emotional composition ratio of the emotional components may be different.

The emotional intensity of the emotional component of the emotional type, which indicates emotional relevance, becomes stronger from left to right.

For example, the emotional types of sadness are denial, anger, bargaining, depression, and acceptance, and the emotional intensity becomes stronger as you go from denial to acceptance.

The control unit 137 forms a first image voice table in which the hologram image size and voice volume corresponding to the emotion composition ratio are set.

The control unit 137 generates the hologram image size and voice size based on a preset first image voice table according to the emotion composition ratio.

Here, in the first image voice table, the holographic image size and voice size are preset according to the emotional composition ratio of each emotional component.

The hologram image size and voice size increase as the emotional composition ratio of each emotional component approaches 100%, and decrease as it approaches 0%.

As for the holographic image size and voice size, as the emotional intensity of the emotional component increases, the weight value preset for the emotional component increases, resulting in a larger holographic image size and voice size.

The emotional intensity of sadness increases in the following order: denial, anger, compromise, depression, and acceptance. Therefore, assuming that the weight of denial is 0.1, the weight of anger is 0.15, the weight of compromise is 0.2, the weight of depression is 0.25, and the weight of acceptance is 0.3, the control unit 137 bases the emotion component on the corresponding emotion component when the emotion component ratio is 50% or more. The set weight is multiplied by the hologram image size and voice size corresponding to the emotional component to change the hologram image size and voice size.

In other words, the control unit 137 uses the image voice table if the emotional composition ratio is 50% denial, 5% anger, 0% compromise, 45% depression, and 0% acceptance based on 100% using the emotion word of death. The holographic image size and voice size are extracted based on the emotional composition ratio of each emotional component, and the extracted holographic image size and voice size are multiplied by a negativity weight of 0.1 to finally generate the holographic image size and voice size.

A second specific method for setting the hologram image size and voice size will be described as follows.

The emotion dictionary storage unit 135 stores emotion types according to emotion words, emotion components belonging to the emotion type, and emotion scores.

The emotion dictionary storage unit 135 stores an emotion score table in which emotion components and emotion scores belonging to emotion types are preset.

Each emotional component assumes 100 points as the maximum value.

For example, if the text of the book data in the emotion dictionary storage unit 135 is “I am depressed,” the control unit 137 determines that it belongs to the emotion type of sadness and uses the emotion word of depression using the emotion score table. The emotional scores of 0 points for denial, 0 points for anger, 0 points for compromise, 100 points for depression, and 0 points for acceptance are extracted, and the extracted emotional scores are added to calculate the total emotional score (100 points).

If the text of the book data in the emotion dictionary storage unit 135 is “I want to die,” the control unit 137 determines that it belongs to the emotion type of sadness and uses the emotion score table to score 50 negative points using the emotion word of death. , emotion scores of 30 points for anger, 40 points for compromise, 80 points for depression, and 60 points for acceptance are extracted, and the extracted emotional scores are added to calculate the total emotional score (260 points).

The control unit 137 forms a second image voice table in which the hologram image size and voice volume are set corresponding to the calculated total emotional score.

For example, if the total emotion score is 250 to 280 points, set the hologram image size to 10 and voice volume to 8, and if the total emotional score is 100 to 130 points, set the hologram image size to 5 and voice volume to 4. The hologram image size and voice size are preset according to the total emotional score.

The control unit 137 generates the hologram image size and voice size based on a preset second image voice table according to the total emotional score.

Here, in the second image voice table, the holographic image size and voice size are preset according to the total emotional score that is the sum of the emotional scores of each emotional component.

The control unit 137 matches and synchronizes the book data, hologram content, and voice data corresponding to the extracted content with the hologram image size and voice size generated by the first or second method described above.

The control unit 137 generates hologram content including synchronized video, hologram image size, voice, and voice size, and transmits it to the hologram audiobook device 120 through the communication unit 136.

The control interface unit 124 of the hologram audiobook device 120 receives hologram content from a content providing server and transmits hologram image size information of the image included in the received hologram content to the image display means 126. The image display means 126 adjusts the image to the size of the hologram image and transmits it to the pyramid reflector.

The image reflected through the pyramid reflector has different positions and sizes depending on the wavelength and angle of the light, and when combined, it forms a 3D hologram.

At this time, the control interface unit 124 transmits audio and audio volume information synchronized with the video to the speaker driver.

The speaker driver outputs audio at a size corresponding to the video through the speaker 123b. The hologram audiobook device 120 simultaneously outputs a 3D hologram and the corresponding synchronized voice.

Users can view 3D hologram images of various sizes and listen to voices of various sizes depending on the content of the book data.

The control unit 137 receives feedback information in real time from the hologram audiobook device 120 through the communication unit 136.

The feedback information may be voice information of users playing and watching hologram content on the hologram audiobook device 120.

The control unit 137 receives feedback information including voice information and hologram content playback time, and stores the received feedback information in the book data database unit 131.

The control unit 137 may analyze feedback information to determine whether the form or aspect of the viewer's response was good or bad in a section when playing holographic content.

The control unit 137 analyzes the feedback information (voice information), refers to the viewers' reactions that change according to the emotional words, and applies it when configuring the holographic image size and voice size according to the emotional words.
