The length adjusting module comprises first and second fastening units configured to be assembled and disassembled and configured to be locked together in a fastened position when assembled. When the first and second fastening units are assembled, the first fastening unit is electrically connected to the second fastening unit and a length of the length adjusting module is adjusted. ## Claims ### Claim 1 An operating method of a wearable device including a module for adjusting a length of the wearable device, the operating method comprising: determining, by the wearable device, a length of the wearable device, based on electrical connection information between a first fastener and a second fastener of the wearable device; determining, by the wearable device, whether the determined length corresponds to one of a plurality of preset lengths for a user, each preset wearing length for the user corresponding to one of a plurality of different applications executable by the wearing device; based on determining that the determined length corresponds to one of the plurality of preset lengths for the user, executing, by the wearable device, the application corresponding to the determined length; and outputting, by the wearable device, information with respect to the executed application. ### Claim 2 (depends on 1) The operating method of claim 1, further comprising blocking execution of any of the different applications, based on determining that the determined length corresponds to none of the preset wearing lengths. ### Claim 3 (depends on 1) The operating method of claim 1, further comprising: obtaining user ID information based on a user input; identifying a user of the wearable device based on the obtained user ID information; determining whether the determined length corresponds to one of a plurality of preset lengths of the identified user; and executing an application corresponding to the identified user based on the determined wearing length, based on determining that the determined length corresponds to one of preset lengths for the identified user. ### Claim 4 (depends on 1) The operating method of claim 1, further comprising: determining, by the wearable device, an operating mode corresponding to the determined length; executing, by the wearable device, an application corresponding to the determined operating mode; and outputting, by the wearable device, information corresponding to the determined operating mode. ### Claim 5 (depends on 4) The operating method of claim 4, wherein the operating mode of the wearable device comprises one or more selected from a normal mode, a sleeping mode, an exercise mode, or a measurement mode. ### Claim 6 (depends on 4) The operating method of claim 4, further comprising, based on the determined operating mode being the sleeping mode, performing a setting to terminate a certain function being executed by the wearable device. ### Claim 7 (depends on 6) The operating method of claim 6, wherein the certain function comprises one or more selected from a position sensing function, an atmospheric pressure sensing function, a temperature sensing function, a Wi-Fi function, or a Bluetooth function. ### Claim 8 A wearable device comprising: a processor configured to: determine a length of the wearable device, based on electrical connection information between a first fastener and a second fastener of the wearable device; determine whether the determined length corresponds to one of a plurality of preset lengths for a user, each preset wearing length for the user corresponding to one of a plurality of different applications executable by the wearing device; based on determining that the determined length corresponds to one of the plurality of preset lengths for the user, execute the preset application corresponding to the determined wearing length; and output information with respect to the executed applicatin. ### Claim 9 A non-transitory computer-readable recording medium having recorded thereon a program which, when executed, by a processor of a wearable device, causes the wearable device to execute: determining a length of the wearable device based on electrical connection information between a first fastener and a second fastener of the wearable device; determining whether the determined length corresponds to one of a plurality of preset lengths for a user, each preset wearing length for the user corresponding to one of a plurality of different applications executable by the wearing device; based on determining that the determined length corresponds to one of the plurality of preset lengths for the user, executing the preset application corresponding to the determined length; and outputting information with respect to the executed application.
