select at least one string from a plurality of strings based on the detected data related to the state of the user wherein the selected at least one string is associated with the determined health state of the user; and control the communicator to transmit a message including the selected at least one string to a receiver device. ### Claim 2 (depends on 1) The wearable device of claim 1, wherein the data related to the state of the user comprises at least one of data related to a movement of the user, data related to a location of the user, or data related to a biometric signal of the user. ### Claim 3 (depends on 2) The wearable device of claim 2, wherein the selected at least one string is further associated with the location of the user. ### Claim 4 (depends on 1) The wearable device of claim 1, wherein the at least one processor is further configured to: determine whether the user is in danger based on the determined health state of the user, wherein the at least one string is selected from the plurality of strings in response to determining that the user is in danger. ### Claim 5 (depends on 1) The wearable device of claim 1, wherein the at least one processor is further configured to: display a string set including strings corresponding to the state of the user from the plurality of strings; and control the communicator to transmit the message including at least one string, included in the string set, selected by a user input to the receiver device. ### Claim 6 (depends on 5) The wearable device of claim 5, wherein the at least one processor is further configured to display the at least one string selected by the user input; and wherein the message includes the at least one string selected based on the user input and the at least one string selected based on the data related to the state of the user from the plurality of strings. ### Claim 7 (depends on 1) The wearable device of claim 1, wherein the selected at least one string is further associated with at least one from among name, age, gender, or identification information of the user. ### Claim 8 (depends on 1) The wearable device of claim 1, wherein the at least one processor is further configured to: obtain information about the receiver device; and select the at least one string from the plurality of strings based on the data related to the state of the user and the information about the receiver device. ### Claim 9 (depends on 8) The wearable device of claim 8, wherein the information about the receiver device comprises intimacy information indicating a relationship between the user and a user of the receiver device; and wherein the at least one processor is further configured to select the at least one string from the plurality of strings based on the data related to the state of the user and the intimacy information. ### Claim 10 (depends on 8) The wearable device of claim 8, wherein the information about the receiver device comprises a record of strings included in past messages between the wearable device and the receiver device; and wherein the at least one processor is further configured to select the at least one string from the plurality of strings based on the data related to the state of the user and the record. ### Claim 11 A method of transmitting a message at a wearable device, the method comprising: determining a health state of a user based on data related to the state of the user, wherein the data is detected by a sensor of the wearable device; selecting at least one string from a plurality of strings based on the detected data related to the state of the user, wherein the selected at least one string is associated with the determined health state of the user; and transmitting the message including the selected at least one string to a receiver device. ### Claim 12 (depends on 11) The method of claim 11, wherein the data related to the state of the user comprises at least one of data related to a movement of the user, data related to a location of the user, or data related to a biometric signal of the user. ### Claim 13 (depends on 12) The method of claim 12, wherein the selected at least one string is further associated with the location of the user. ### Claim 14 (depends on 11) The method of claim 11, further comprising: determining whether the user is in danger based on the determined health state of the user; wherein the at least one string is selected from the plurality of strings in response to determining that the user is in danger. ### Claim 15 (depends on 11) The method of claim 11, further comprising: displaying a string set including strings corresponding to the state of the user from the plurality of strings; wherein the transmitting of the message comprises: transmitting the message including the at least one string, included in the string set, selected by a user input to the receiver device. ### Claim 16 (depends on 15) The method of claim 15, further comprising: displaying the at least one string selected by the user input; wherein the message includes the at least one string selected based on the user input and the at least one string selected based on the data related to the state of the user from the plurality of strings. ### Claim 17 (depends on 11) The method of claim 11, wherein the selected at least one string is further associated with at least one from among name, age, gender, or identification of the user. ### Claim 18 (depends on 11) The method of claim 11, wherein the selecting of the at least one string comprises: obtaining information about the receiver device; and selecting the at least one string from the plurality of strings based on the data related to the state of the user and the information about the receiver device. ### Claim 19 An electronic device for transmitting a message by using a wearable device to a receiver device, the electronic device comprising: a communicator; and at least one processor configured to: control the communicator to receive, from the wearable device, data related to a state of a user obtained from the wearable device; determine a health state of the user based on the data related to the state of the user; select at least one string from a plurality of strings based on the data related to the state of the user, wherein the selected at least one string is associated with the determined health state of the user; and control the communicator to transmit to the receiver device the message including the selected at least one string. ### Claim 20 A method of transmitting a message, the method comprising: receiving, at an electronic device, data related to a state of a user obtained from a wearable device;
