DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
First of all, a communication for delivering feeling according to the present invention basically supports at least one service of voice communications, video communications, message transfer communications (e.g., SMS), and packet communications.
Hence, transmitting and receiving side mobile terminals shown in FIG. 1 and FIG. 2 support the service(s) of the communication system, thereby enabling to transfer multimedia including video, characters, text, data, and the like as well as voice.
FIG. 1 is a block diagram of a transmitting side mobile terminal according to the present invention.
Referring to FIG. 1, a transmitting side mobile terminal according to the present invention includes a first block 10 periodically collecting bio-informations of a sender who is currently communicating, a second block 20 generating feeling data indicating a current feeling state of the sender using the bio-informations collected by the first block 10, and a third block 30 transferring the feeling data generated from the second block 20 together with a signal of a currently used communication service. Moreover, the transmitting side mobile terminal further includes a block for converting the feeling data to a transmittable signal format to enable the feeling data to be transferred together with the signal of the currently used service.
The first block 10 includes a physiological state collecting unit 11 and a biorhythm generating unit 12.
The physiological state collecting unit 11 extracts the bio-informations of the sender who is currently communicating. The physiological state collecting unit 11 includes a plurality of sensors for measuring a physiological state of the sender, i.e., action of the autonomic nervous system. The sensors may include a first sensor for measuring a body temperature of the sender, a second sensor for measuring a respiration of the sender, a third sensor for measuring a pulse of the sender, a fourth sensor for measuring a degree of electric skin reflection of the sender, a fifth sensor for measuring a blood pressure of the sender, and a sixth sensor for measuring a blood flow of the sender. For example, the second sensor measures the respiration by recognizing the sound and volume of breathing. The sensors for measuring the action of the autonomic nervous system of the sender are addible or changeable if necessary, and are not limited to these examples.
The biorhythm generating unit 12 computes a current biorhythm based on date of birth previously inputted by the sender.
The third block 30 encodes the feeling data generated from the second block 20 on a communication signal, i.e., a signal of a communication service the sender is currently using, and then transfers the encoded data/signal.
In this case, the communication signal is a voice signal for a voice communication. Hence, the feeling data generated from the second block 20 is transmitted via a traffic channel allocated to the transmission of the voice signal. In order to avoid having influence on a load of the traffic channel, it is also able to transmit the feeling data via a control channel allocated for a control of the voice communication. Such a channel adoption can be variously modified according to a channel adopting method of a communication system.
Besides, the communication signal may be a video signal for a video communication, an SMS signal for character transmission, or a packet signal for a packet communication. Namely, the communication signal depends on the kind of the mutual communications.
The feeling data generated from the second block 20 in FIG. 1 is a statistical numerical value representing a feeling of the sender. Namely, the feeling data is a result of a function using the measured values of the autonomic nervous system action as its inputs. The function is implemented by an experiment to be appropriate for expressing a feeling of a normal human being according to an action of the autonomic nervous system.
For instance, statistical numerical values of the feeling data are set to 1 ̃3, respectively. First of all, it is assume that ‘1’, ‘2’, and ‘3’ indicate an ‘excited state’, a ‘normal state’, and an ‘angry state’, respectively. And, it is also assumed that result values ‘1 ̃30’, ‘31 ̃60’, and ‘61 ̃90’ of the function correspond to the numerical values ‘1’, ‘2’, and ‘3’ of the feeling data, respectively. A predetermined input value is inputted to the function of computing the feeling data by substitution. By confirming the computed result of the substitution corresponds to which one of the statistical numerical values, a feeling data value is found to be transmitted to a receiving side.
FIG. 2 is a block diagram of a receiving side mobile terminal according to the present invention.
Referring to FIG. 2, a receiving side mobile terminal according to the present invention includes a fourth block 40 extracting feeling data from a signal received from a transmitting side mobile terminal of FIG. 1 and a fifth block 50 disclosing a feeling corresponding to the feeling data extracted from the fourth block 40. And, the receiving side mobile terminal further includes a block (not shown in the drawing) converting a signal format of the feeling data extracted from the fourth block 40 to a value analyzable in an internal processor.
Moreover, the receiving side mobile terminal further includes a look-up table 60 for searching a sender's feeling corresponding to the feeling data extracted from the fourth block 40.
The look-up table 60 generalizes human feelings to turn into numerical values. And, the look-up table 60 stores various kinds of human feelings previously calculated into statistical numerical values. Moreover, the look-up table 60 includes output data corresponding to the various feelings. The output data are outputted via output means (display window and/or speaker) of the mobile terminal.
Hence, the fifth block 50 searches to compare the value of the feeling data extracted from the fourth block 40 to the statistical numerical values of the look-up table 60, searches a value corresponding to a result of the comparison to grasp the corresponding feeling, and then outputs an output data corresponding to the grasped feeling via an output means.
For instance, the statistical numerical values stored in the look-up table according to the respective feelings are set to 1 to 3, respectively. And, it is assumed that ‘1’, ‘2’, and ‘3’ indicate an ‘excited state’, a ‘normal state’, and an ‘angry state’, respectively. If the value of the feeling data extracted from the fourth block 40 is ‘3’, the fifth block grasps that the sender is in the ‘angry state’ by referring to the look-up table 60 and then outputs the output data corresponding to the ‘angry state’.
Consequently, by referring to the look-up table 60, the fifth block 50 outputs the feeling state corresponding to the feeling data extracted from the fourth block 40 in the form of one of text or voice. Instead, the fifth block 50 may output the feeling corresponding to the extracted feeling data in the form of combination including at least one of image, text, and voice. Specifically, the output data stored in the look-up table are listed as following: 1) Images—still pictures and/or moving pictures disclosing facial expressions according to human feelings (angry, smiling, normal, etc.); 2) Texts—sentences or paragraphs disclosing human feeling (angry, pleasant, normal, etc.) or indications of truthfulness (lying or telling truth currently); and 3) voices—sounds (synthesized) expressing human feeling or indications of truthfulness.
As can be seen from the above description, the transmitting side mobile terminal transmits the feeling of the sender who is currently in communications by real time and the receiving side mobile terminal grasps the current feeling of the sender while in communications.
FIG. 3 is a flowchart of a method of collecting, inserting, and transferring feelings using a transmitting side mobile terminal according to the present invention.
Referring to FIG. 3, a transmitting side mobile terminal is currently communicating with a receiving side mobile terminal. In doing so, the transmitting side mobile terminal periodically collects bio-informations of a sender (S1).
In this case, the bio-informations include sender's physiological information and sender's current biorhythm information.
The physiological information is for the action of the autonomic nervous system of the sender in calling, and more specifically, for sender's body temperature, respiration, pulse, degree of electric skin reflection, blood pressure, and blood flow which are measured by the transmitting side mobile terminal.
And, the biorhythm information is computed based on the date of birth previously inputted by the sender.
The transmitting side mobile terminal generates feeling data disclosing a current feeling of the sender in communication using the collected bio-informations (S2).
In this case, the generated feeling data is a statistical numerical value representing the sender's current feeling.
Subsequently, the transmitting side mobile terminal transmits the generated feeling data together with a communication signal, i.e. a signal of a currently used communication service (S3). Moreover, the present invention may further include a step of converting the generated feeling data to a signal format that is transmittable together with the signal of the current communication system to be appropriate for the diversification of communication systems. Such a converting step is optional.
In case of currently-using a voice communication service, the transmitting side mobile terminal transmits the feeling data together with a voice signal for the voice communication. Specifically, the transmitting side mobile terminal transmits the generated feeling data via a traffic channel allocated to the transmission of the voice signals. Instead, the transmitting side mobile terminal may transmit the generated feeling data via a control channel allocated for a control of the voice communication. Such a channel use can be variously modified according to a channel use method of the communication system. The feeling data may be transmitted via any other type of channel as well, as the present invention is not limited to transmission via any particular type of channel. Meanwhile, the transmitting side mobile terminal transmits the feeling data together with the voice signal in a manner that the feeling data is encoded on the voice signal to transmit via the corresponding channel, for example.
Besides, in case of currently using a video communication service, the transmitting side mobile terminal transmits the feeling data together with a video signal for the video communication. In case of currently using SMS (short message service), the transmitting side mobile terminal transmits the feeling data together with a short message signal. In case of currently using a packet communication service, the transmitting side mobile terminal transmits the feeling data together with a packet signal. Meanwhile, the feeling data is transmitted in various forms according to what communication service the transmitting and receiving side mobile terminals are currently using.
FIG. 4 is a flowchart of disclosing feelings using a receiving side mobile terminal according to the present invention.
Referring to FIG. 4, a receiving side mobile terminal, which is in mutual communications, periodically extracts feeling data from a received signal (S10). This is to disclose sender's current feelings in mutual communications.
The receiving side mobile terminal discloses the extracted feeling data via various means (e.g., display window and/or speaker) (S20). In this case, the disclosed feeling data has one of image, text, and voice forms expressing the sender's current feeling. Instead, the feeling data may have a combination form including at least one of image, text, and voice.
Examples of forms of disclosing the feeling data are listed as following: 1) Images—still pictures and/or moving pictures disclosing facial expressions according to human feelings (angry, smiling, normal, etc.); 2) Texts—sentences or paragraphs disclosing human feeling states (angry, pleasant, normal, etc.) or polygraphing results (lying or telling truth currently); and 3) voices—sounds (synthesized) expressing human feeling states or polygraphying results.
For additional instance, in case of using a mobile terminal equipped with a look-up table including statistical numerical values corresponding to various feelings by generalizing human feelings and output data corresponding to the various feelings, the receiving side mobile terminal previously searches to compare a value of the extracted feeling data to the statistical numerical values of the previously prepared look-up table, searches a value corresponding to a result of the comparison to grasp the corresponding feeling, and then discloses output data corresponding to the grasped feeling data. In doing so, the output data correspond to the disclosed forms of the feeling data.
Accordingly, the present invention delivers the user's feeling by real time as well as transmits/receives voice/image(video)/characters/text, etc., thereby enabling efficient transfer of intensions (mutual understanding) between the sender and recipient.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
