  Next, the operation of the network system in this embodiment will be described separately for each operation of (a) wrist terminal server 15, (b) mobile terminal 12, and (c) wrist terminal 11.

(A) Operation of Wrist Terminal Server 15 FIG. 7 is a flowchart showing the operation of the wrist terminal server 15. The process shown in this flowchart is executed by a CPU (not shown) provided in the wrist terminal server 15 reading a predetermined program.

  The wrist terminal server 15 receives distribution information from the various content servers 14a and 14b existing on the network 13 (step A11), and processes the distribution information for the wrist terminal (step A12). The wrist terminal server 15 stores the processed distribution information in the wrist terminal memory 41 shown in FIG. 8 (step A13).

  The wrist terminal memory 41 is provided for each wrist terminal. In the list terminal memory 41, ID information (identification information) unique to the list terminal 11 held by the user, the distribution content type selected by the user, and other various setting information are recorded as the user information 41a. Further, as the distribution information 41b, distribution information received from the various content servers 14a and 14b and processed for the wrist terminal is stored. “Processing for wrist terminal” means performing processing such as editing content information in accordance with the screen of wrist terminal 11 having a wristwatch size.

  The wrist terminal server 15 refers to the wrist terminal memory 41 and selectively receives various pieces of content information for each user, processes each of them, and stores them in the wrist terminal memory 41.

(B) Operation of Mobile Terminal 12 FIG. 9 is a flowchart showing an operation related to the list distribution application of the mobile terminal 12. Note that the processing shown in this flowchart is executed by the CPU 31 provided in the mobile terminal 12 reading the program 35 a stored in the memory 35.

  First, the user taps a setting icon (not shown) provided on the screen of the mobile terminal 12 to activate the “list terminal setting” function. When the “list terminal setting” function is activated (Yes in step B11), the mobile terminal 12 (specifically, the CPU 31) connects to the wrist terminal server 15 via the network 13, and the wrist terminal server 15 sets the wrist terminal setting. A predetermined setting screen is received and displayed (step B12).

  When the user performs a setting operation on the screen of the mobile terminal 12 (step B13), the mobile terminal 12 holds the information set by the setting operation in the memory 35, and transmits the list to the list terminal 11 to transmit the list. It memorize | stores in the memory 25 of the terminal 11 (step B14). The setting information is also transmitted to the wrist terminal server 15, and the setting information is registered in the wrist terminal memory 41 (step B15).

  When the setting information at this time is sent to the wrist terminal 11, when the user performs a predetermined operation, desired content information is displayed according to the set priority order. In addition, the user can check the setting contents at any time on the screen of the wrist terminal 11.

  When the preset traveling time is reached (Yes in step B16), the mobile terminal 12 accesses the wrist terminal server 15 via the network 13 and receives the content information stored in the wrist terminal memory 41 ( Step B17). The content information received at this time is stored in a predetermined area of the memory 35. Then, when there is a distribution request from the list terminal 11 (Yes in Step B18), the portable terminal 12 reads the content information stored in the predetermined area of the memory 35 and transfers it to the list terminal 11 (Step B19). ). The content information transferred from the portable terminal 12 to the wrist terminal 11 has already been processed for the wrist terminal by the wrist terminal server 15.

  The content information transferred to the wrist terminal 11 is displayed according to a preset priority order when the user performs a predetermined operation. The predetermined operation is an operation of turning the wrist (flip operation).

Here, a method for setting the priority order of information will be described.
FIG. 10 is a diagram showing the configuration of the priority order setting screen 51 of the mobile terminal 12. FIG. 11 is a diagram showing the configuration of the priority order setting table 53.

  The mobile terminal 12 has a function for setting information priorities. When the priority setting function is activated by a predetermined operation, a priority setting screen 51 is displayed on the display unit 32 of the mobile terminal 12. On this priority setting screen 51, five selection items 52a to 52e such as “normal”, “walking”, “train”, “driving”, and “night” are provided as states relating to the daily life of the user. Yes.

  The priority order of information can be set for each of the selection items 52a to 52e. In the example of FIG. 10, when walking, “now where (map service)” is set as the first information, and “weather information” is set as the second information. “First time, second time” refers to the number of times that the wrist is turned (flip operation).

  When the priority order of information is set, the setting contents are registered in the priority order setting table 53 as shown in FIG. The priority order setting table 53 is provided in the memory 35 of FIG. 6, and the contents registered therein are transmitted as setting information of the wrist terminal 11 to the wrist terminal 11 and the wrist terminal server 15 (step B14 in FIG. 9). , B15).

(C) Operation of the wrist terminal 11 FIG. 12 is a flowchart showing the operation of the state registration process of the wrist terminal 11. Note that the processing shown in this flowchart is executed by reading the program 25 a stored in the memory 25 by the CPU 21 provided in the wrist terminal 11. The same applies to the processing shown in the flowcharts of FIGS. 14 and 15 described later, and is executed by the CPU 21 reading the program 25a.

  In the apparatus main body 11 a of the wrist terminal 11, a motion detection sensor such as an acceleration sensor is installed as the sensor unit 26. The wrist terminal 11 performs the following state registration process in order to associate the output data of the motion detection sensor with the user state.

  That is, first, when the user is in a walking state, for example, a setting icon (not shown) provided on the screen of the wrist terminal 11 is tapped to activate the “state registration” function. When the “state registration” function is activated (Yes in step C11), the wrist terminal 11 (specifically, the CPU 21) continuously outputs the output data of the motion detection sensor provided in the sensor unit 26 to a predetermined area of the memory 25. (Step C12).

  When there is an operation for ending registration (Yes in Step C13), the wrist terminal 11 uses the output data of the sensor unit 26 recorded in the predetermined area of the memory 25 as the data relating to the state during walking as shown in FIG. Temporarily registered in the table 54 (step C14). The state table 54 is provided in the memory 25. The provisional registration is performed because the user appropriately determines and confirms the registration contents.

  The same applies to other states, and the actual movement in the user's daily life can be achieved by performing the same state registration at the time of driving, riding on a train, and at night at normal times. It is possible to associate the output data of the motion detection sensor by and the state at that time. As a result, the user's state can be accurately determined, and information according to the state at that time can be preferentially displayed.

  FIG. 14 is a flowchart showing the operation of the information acquisition process of the wrist terminal 11.

  The wrist terminal 11 (specifically, the CPU 21) checks the connection state with the portable terminal 12 at regular intervals (step D11) and determines whether communication is possible (step D12). If communication is possible, that is, if wrist terminal 11 and portable terminal 12 are in a state where short-range wireless communication is possible (Yes in step D12), wrist terminal 11 receives content information from portable terminal 12 and It is stored in 35 predetermined areas (step D13). This content information is periodically received by the mobile terminal 12 from the wrist terminal server 15 (see step B17 in FIG. 9), and is processed for the wrist terminal.

  FIG. 15 is a flowchart showing the operation of the information display process of the wrist terminal 11.

  The wrist terminal 11 (specifically, the CPU 21) analyzes the output data of the motion detection sensor provided in the sensor unit 26, and determines what state the user is in based on the analysis result (step E11). Specifically, the wrist terminal 11 refers to the state table 54 shown in FIG. 13 to determine whether the output data of the sensor unit 26 is “normal”, “walking”, “train”, “driving”, or “nighttime”. Judge whether it corresponds to the state.

  In general, when the user is walking with the wrist terminal 11 worn on his / her wrist, the user often sways back and forth with his arms lowered, so sensor data representing such an operation is obtained. It is done. If the user is driving, since the steering wheel is operated, sensor data representing such an operation can be obtained. If the user is on the train, there is an operation such as grabbing a hanging leather or sitting on a seat while in the vehicle, and sensor data representing such an operation can be obtained. Moreover, if it is normal, the sensor data according to a user's normal pattern are obtained. The same is true at night.

  In addition to the analysis of the sensor data, the current state of the user can be more accurately determined by using the position data of the GPS unit 28.

  The wrist terminal 11 determines whether the user is turning his / her wrist using the output data of the sensor unit 26 (Step E12). If the user is turning his / her wrist (Yes in Step E13), the wrist terminal 11 determines that the flip operation shown in FIG. 4 is being performed, and switches from the clock screen which is the reference screen to the information display.

  Specifically, the wrist terminal 11 refers to the priority setting table 53 shown in FIG. 11 stored in the memory 25, and stores various information from a predetermined area of the memory 25 based on the user's state and the number of times the wrist is turned. The data is selectively read out and displayed on the screen of the display unit 22 (step E14). Thus, for example, when the user is “walking”, if the user raises his arm to the face position and performs a flip operation once, information on “now where (map service)” is displayed, and the flip operation is performed twice. In such a case, “weather information” is displayed.

  In addition, when the user performs an operation with the arm lowered (Yes in Step E15), the wrist terminal 11 returns from the information display to the clock screen that is the reference screen (Step E16). On the other hand, if the wrist is not turned or the arm is not lowered (No in Step E15), the wrist terminal 11 determines the user's state while maintaining the current display state (Step E17).

  As described above, according to the present embodiment, various information on the network received by the mobile terminal 12 can be confirmed by the wrist terminal 11. In this case, when the user performs a predetermined operation while holding the wrist terminal 11, information relating to preset items is selectively displayed from these pieces of information. Therefore, it is possible to easily display and check only necessary information at any time without a troublesome operation for displaying information.

  Further, by determining the user's state using the output data of the sensor, information corresponding to the user's state at that time, such as when walking or on a train, can be displayed. In this case, if the sensor output data obtained by actual movement in the daily life of the user is associated with the state at that time in advance, the current state of the user can be correctly determined to display information. .

  If information priorities are set, each time a predetermined operation is performed, various information can be viewed according to the priorities.

  The wrist terminal 11 has a wristwatch shape that can be worn on the user's wrist, and acquires various types of information by short-range wireless communication from a portable terminal placed in a bag or the like. The user can selectively view these pieces of information simply by performing an operation such as turning the wrist while wearing the wrist terminal 11 on the wrist. The user's operation for switching display information is not limited to turning the wrist, and may be, for example, an operation of shaking an arm, an operation of applying vibration to the arm, or the like.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
