The development of the processing capabilities and wireless communications of mobile terminals (eg, mobile phones, PDAs, etc.) allows users to communicate various information such as voice, music, pictures, video, and the like. Mobile terminals are widely used to store contact information about other users, and use the information to easily recognize the other party. For example, when a call is received from an individual whose contact information is stored in the mobile phone, the information (for example, telephone number, name, etc.) of the individual is displayed on the display device of the mobile phone. Mobile terminals are also used to store user's personal information such as names, telephones, and the like.

Some mobile terminals allow users to express themselves using avatars. For example, the user selects an avatar that can represent the user using the mobile terminal. The avatar represents the user as digital information in the virtual environment of the mobile terminal, and is generally used as a virtual character representation of the user displayed on the mobile terminal. When communicating with another mobile terminal, the avatar of the mobile terminal can be transmitted to the other terminal as a representation of the sender.

However, conventional avatars used in mobile terminals are generally relatively simple characters that are manually selected by the user. For example, a conventional avatar used for a mobile terminal is a character shape (eg, an animal, a cartoon character, or a three-dimensional image of a user) that is generally selected according to a user's preference. The user may select an avatar, such as a character shape (eg, a smiling face, a sad face, an angry face, etc.) having an expression necessary to reflect his or her current state or personality. The selected avatar is displayed on the mobile terminal and sent to another user.

Conventional mobile terminals also allow users to express themselves using color. For example, some mobile terminals provide inserts (or exterior cases) of various colors. The user changes the color of the terminal by changing the insert according to his preference.

However, these conventional techniques generally require the user to manually select an avatar or color to represent or represent themselves. Because avatars and colors are manually selected by the user according to the user's preferences, the avatars and colors may not accurately and realistically represent the user's state or personality at a particular time. In addition, whenever the user's state or preference changes, the avatar and color of the mobile terminal must be manually reconfigured.

Accordingly, there is a need for a mobile terminal that can realistically provide a representation of a user's state or characteristics at a particular time. It is also desirable for the mobile terminal to automatically generate and update its representation as the user's status or personal characteristics change.

The present specification is capable of automatically generating and updating a character entity representing a user's status based on user characteristic data, such as a user's biological signal and personal information. A personal communication device or a mobile terminal. The mobile terminal may provide a physical or external representation of the character entity in a plurality of forms such as an avatar, color, sound, and the like. The character entity of the mobile terminal may change according to changes in user characteristics such as biological signals or personal information.

In one embodiment, the mobile terminal includes an input interface and a memory. The input interface receives user characteristic data of the user, and the memory stores the received user characteristic data. The mobile terminal is configured to generate a character entity representing the state of the user based on the received user characteristic data.

In another embodiment, a system for synthesizing a character entity includes an input device and a server. The input device is configured to receive the character entity from at least two mobile terminals. The server is configured to synthesize a new character entity based on the received character entity. The server transmits the synthesized character object to the mobile terminal or another mobile terminal, and the mobile terminal which receives the synthesized character object stores the character object or performs further processing.

In yet another embodiment, a system for synthesizing a character entity includes a memory, an input device, and a processing device. The memory stores the character entity, and the input device is configured to receive another character entity from the mobile terminal. The processing device is configured to synthesize a new character object based on the stored character object and the received character object.

In yet another embodiment, a method of generating a character entity in a mobile terminal includes receiving a first set of user feature data of a user and a character entity representing a state of the user based on the first set of received user feature data. Generating a step. The character object is stored in the memory of the mobile terminal.

In another embodiment, a method of synthesizing a character entity includes uploading at least two character entities from at least two mobile terminals to a server coupled to the mobile terminal. New character objects are synthesized based on the character objects uploaded to the server.

In another embodiment, a mobile terminal capable of displaying a plurality of colors includes a memory and a processing module. The memory receives and stores user characteristic data of the user. The processing module receives and analyzes user feature data from the memory and assigns colors to at least a portion of the mobile terminal in response to the received user feature data.

In another embodiment, a method of changing colors in a mobile terminal capable of displaying a plurality of colors includes receiving user feature data of a user and colorting at least a portion of the mobile terminal in response to the received user feature data. The step of assigning. The assigned color is displayed on at least a portion of the mobile terminal.

In the following, detailed descriptions of various embodiments are described. However, it will be apparent that these embodiments may be practiced without some or all of those described in detail below. In other instances, steps or components of well-known methods have not been described in detail in order not to unnecessarily obscure the contents of this specification.

The present disclosure provides a system and method for creating and modifying a character entity representing a user's state on a mobile terminal. The character entity characterizes the user's state based on biological data obtained from the user and / or other user characteristics (eg, schedule, pattern of phone calls, messages exchanged with other users, etc.). Once a character entity is created, the mobile terminal provides a physical or external representation of the character entity, such as an avatar, color, sound, or the like. The mobile terminal receives an avatar from another mobile terminal or server computer or transmits an avatar to the mobile terminal or server computer. In one embodiment, a mobile terminal (eg, a mobile phone) is made of a material such as an electro-luminescent material that can change color in accordance with biological data or other user characteristics. Accordingly, embodiments described herein provide a technique for realistically characterizing the state of a user on a mobile terminal. An avatar generally means a graphical or virtual character representation, such as an individual's smiley face or appearance. However, herein, "avatar" is not limited to this example and may include representation by animation, sound, color, vibration, or a combination thereof.

1 illustrates an example mobile terminal 110. As shown, the mobile terminal 110 receives an input interface ("bio-signal") of the user from the bio-sensor 130 via the communication link 140 (bio-signal) ( 113). The biosensor 130 includes one or more sensors for sensing a bio signal of a user, which will be described in detail below. Mobile terminal 110 may also receive bio signals in the form of biological data from a remote biosensor, server or other mobile terminal via a wireless or wired communication link.

In the mobile terminal 110, the memory 116 is connected to the input interface 113 to receive and store bio signals. In addition, the memory 116 may store other user characteristics, such as a user's schedule, patterns of telephone calls, messages exchanged with other users, and the like. For example, the mobile terminal 110 may determine a user's schedule and call pattern (for example, call destination / call destination, number of calls, number of unanswered call destinations, message destination / call destination, number of messages, etc.). The data is stored in the memory 116.

User feature data (eg, a user's bio signal and / or personal information) is processed in a character module 114 coupled to the memory 116. The character module 114 may be implemented using a processor (eg, a CPU), an ASIC or any suitable processing device used in a mobile terminal such as a mobile phone, a PDA, or the like. Character module 114, based on the received data, to display or output on the LCD display device 117 or other components of the mobile terminal, character objects (eg, avatar, color, Sound, vibration, etc.). For example, if the user's biological data indicates a high pulse rate, the character entity can visualize the pulsed heart. Similarly, if the user's schedule indicates that the schedule is full for a particular date, the character entity may be shown running with a briefcase. Also, if the user's data indicates an unhealthy state, the character entity may be displayed in a lying state. In addition or in place of this, a color representing the user's state may be assigned or assigned to the character entity. In the case of an unhealthy user state, for example, the character module 114 may assign a red color to the character entity for display. As used herein, the term "color" means not only the chrominance (eg red, blue, green) but also the luminance (eg gray, black, white).

Once a character entity is created, character module 114 modifies or updates that character entity when new user feature data is received. If the user's new biological data indicates that the user's health status is improving, for example, the character module 114 performs information processing to modify the character entity to reflect that status. In the case of using a lying character, the character entity can be seen as a bedless state in a healthy state.

The mobile terminal 110 may communicate character entity and user characteristic data with an external device such as another mobile terminal, a server, or a computer through the data communication device 112. The data communication device 112 converts the character entity and the user characteristic data to communicate with the external device through the antenna 11. Such data transmission can be carried out, for example, via a cellular network, conventional wireless internet or direct communication between two terminals (eg Bluetooth). The mobile terminal 110 may also include an input / output interface 115 for interfacing with a portable memory card 120 to store or retrieve character objects and / or user feature data.

The mobile terminal 110 may be any kind of personal communication device having a mobile communication function such as a mobile phone, a personal digital assistant (PDA) and a notebook computer. In one embodiment, the outer case for the mobile terminal is made of organic electro-luminescence (EL) or inorganic EL material that can change color or light intensity in response to user characteristic data.

2 illustrates one embodiment of a memory 116 that includes various information and modules used to create a character entity 200. The character entity 200 includes personal information 210, biological information 220, an emotion model 230, a physical model 240, and a behavior engine 250. . The emotion model 230 represents the user's current emotional state, and the body model 240 represents the user's body state. The behavior engine 250 models the behavior of the character entity based on the attributes from the emotional model 230 and the body model 240. As shown in FIG. 2, the character entity 200 is temporarily stored in the memory 116 of the mobile terminal 110, and the character module 114 accesses the memory 116 to access the character entity 200 in real time. Process.

Personal information 210 is managed and updated by character module 114. Personal information 210 may include an address book (e.g., a name or group of names, a corresponding phone number, an email address, and a homepage address), an event (e.g., the name of a meeting, meeting place, start and end times, attendees, Related notes) and patterns of phone calls (for example, the name and phone number of the other party, the start time and length of the phone call, short messages exchanged with other users, the number of phone calls or messages with other users, failed to answer) User information, such as the number of incoming or outgoing messages). The personal information 210 collected by the character module 114 is provided to the emotion model 230 and the behavior engine 250, and the emotion model 230 and the behavior engine 250 are based on the information. To predict. Although not described herein, any method or theory developed in the field of mental or behavioral psychology may be applied to implement the emotional model 230 and the behavior engine 250.

Emotion model 230 and body model 240 are generated and updated using biological information 220 obtained through biosensor 130. In particular, body model 240 represents a user's virtual physiological model by modeling various organs of the user based on biological information 220 (eg, biological signals, data, etc.). . Attributes stored in body model 240 are used to geometrically model the avatar, which represents the character entity 200 in the virtual world. In the above example, personal information was used to model the emotion model and the behavior engine, and biological information was used to model the emotion model and the body model, but each model can also be generated or updated using different kinds of data ( For example, in response to personal information, such as a number of incoming calls, the body model may model the user's tired state).

Referring back to FIG. 1, the mobile terminal 110 receives the biological information 220 of the user through the biosensor 130. The biosensor 130 may be embedded in the mobile terminal 110 or communicate with the mobile terminal 110 via the communication link 140. In most cases, communication link 140 is preferably implemented in a wireless connection, but in other configurations, biosensor 130 may be connected to wireless terminal 110 via a wired connection.

The biosensor 130 is an acoustic sensor 131 such as a microphone, a visual sensor 132 such as a camera, for example, a taste sensor 133 and an olfactory sensor 134 manufactured using nano technology. Or motion sensors 135, such as micro-electro mechanical systems (MEMS) accelerometers. In addition, the biological information 220 of the user may be obtained by measuring the bio signal through the thermometer 136, the pulse sensor 137, or the electrocardiogram (ECG) sensor 138. Although FIG. 1 illustrates a number of different biosensors that may be used in the mobile terminal 110, the sensor 130 may use any number of sensors of any kind capable of sensing the user's physical condition. .

Biological information obtained by the biosensor 130 is transmitted to the memory 116 via the input interface 113. The character module 114 generates and generates an emotional model 230 and a body model 240 of the character entity 200 as described above by accessing and processing the biological and personal information stored in the memory 116. Update

For example, the character module 114 analyzes voice data of the user obtained through the auditory sensor 131 and generates information about the health state of the user. In this case, the character module 114 may model the health state of the user by analyzing the voice using a known algorithm. According to known theories of Oriental medicine or phonetics, an individual's state of health can be known by analyzing the individual's voice.

In addition, the taste sensor 133 and the olfactory sensor 134 may be implemented using a laminated metal oxide sensor, a nano biosensor, and the like, and may include wine, food, depleted food, forged liquor, and dangerous substances. It is used to detect the taste or smell of the lamp. The character module 114 compares the taste and olfactory information obtained by the sensors 133 and 134 with predetermined values to update the corresponding attributes of the body model 240, which is the character entity 200 for the source of that information. Determines the behavior of

The character entity 200 including the emotion model 230, the body model 240, and the behavior engine 250 stored in the memory 116 is transmitted to the portable memory card 120. The portable memory card 120 may be detached from the mobile terminal 110 and attached to another mobile terminal. As such, the user may transmit and manage the character object 200 to a new mobile terminal without having to recreate the character object.

The character entity 200 may further include graphic or animation data, and the emotion model 230 and the body model 240 may be visualized in the form of an avatar using the data. The avatar may be updated or modified in response to the output of the behavioral engine 250 as well as the emotional model 230 and the body model 240 that change over time. The character module 114 visualizes the avatar on the LCD display device 117 using graphic or animation data included in the character object 200.

3 illustrates an embodiment in which mobile terminal 110 may display colors based on user characteristics. In this embodiment, the mobile terminal 110 includes a case 118 made of electro-luminescent (EL) material, such as an organic EL or inorganic EL material. As is well known in the art, cases 118 made of such materials change the intensity or color of light that emits in response to an input signal (eg, a voltage or current signal). The case 118 is made of an EL material, but only a specific portion or any portion of the case of the mobile terminal can be made of the EL material to display a color representing the state of the user.

The character module 114 generates a color input signal for the case 118 based on the attributes of the emotional model 230, the body model 240, and the behavior engine 250. The character entity 200 may include color information to be displayed on the case. In one embodiment, character module 114 analyzes user characteristics and generates color signals to be input to case 118. If the user characteristic data indicates an unhealthy state, a color signal corresponding to red may be generated and provided to the case 118. For example, if the user's voice (which may be input through the biosensor 130 or the internal microphone of the mobile terminal 110) represents an unhealthy state, the character module 114 may display a color signal indicating red color. Outputs In response to the color signal, case 118 displays red on mobile terminal 110. Next, if the user's voice indicates a healthy state, a color signal indicative of blue may be provided for display of case 118. By displaying and changing the color according to the user characteristic data, the user's status is easily and automatically represented on the mobile terminal.

4 illustrates an embodiment in which the mobile terminal 400 can display colors based on user characteristics. In this embodiment, the mobile terminal 400 includes a case 410 made of EL material. As described above, the case 410 is made of a material capable of changing the intensity or color of light emitted according to the input signal. Although the case 410 is made of an EL material, only a specific part or any part of the case or the mobile terminal or the case may be made of the EL material to display a color representing the state of the user.

The processing module 420 analyzes various bio signals input through a sensor, such as the biosensor 430 or the internal microphone 440, and generates, for example, an output signal indicative of the user's current emotion or health condition. Such an output signal of the processing module 420 is used as a color signal input to the case 410, which represents different colors according to the user's emotion or health condition. In response to the color signal, case 410 displays a specific color corresponding to the color signal on mobile terminal 110.
