In addition, the second mode includes a plurality of types of operation modes, for example, the 2a mode and the 2b mode, and when the user switches the operation mode from the first mode to the second mode, the user can Select one to switch the operation mode. Although the second mode includes two types of operation modes, the 2a mode and the 2b mode, this is merely an example, and any number of types of operation modes can be included. Also, hereinafter, the second mode may include the 2a mode and the 2b mode for the sake of simplification of explanation, but it is not limited to this.
At least one of the 2a mode and the 2b mode is a mode for acquiring sensor information from the sensor unit 25 .

Also, the first display control unit 112 may display map information or a predetermined pattern image on the first display unit 18 . Alternatively, the first display control unit 112 may adjust the brightness and color of the displayed image by controlling the light emission of the first display unit 18 .

The setting information acquisition unit 113 acquires setting information in the first mode. This setting information is information used when the mode selection unit 114, which will be described later, selects the 2a-th mode or the 2b-th mode as the second mode. For example, when the user selects the 2a mode or the 2b mode from the display screen of the information processing apparatus 1 as described later, the selection result by the user becomes the setting information.
Alternatively, based on the type and number of sensors that function in the first mode and the type and number of sensors that function in the second mode, when switching to the second mode, which mode to switch to, 2a mode or 2b mode. is determined, the selection result of the 2a-th mode or the 2b-th mode becomes the setting information.
Specifically, the setting information selects the operation mode of mode 2a or mode 2b that is more similar to the type and number of sensors that operate in the first mode. It may be information indicating selection. For example, when the geomagnetic sensor and the acceleration sensor are operating in the first mode, the geomagnetic sensor and the acceleration sensor function in the 2a mode, and the gyro sensor and the illuminance sensor function in the 2b mode, the setting information is: This is information indicating that the 2a mode is to be selected as the second mode.
Alternatively, if the sensor operating before the first mode is stopped is a sensor that functions in the 2a mode, the setting information may be information indicating that the 2a mode is selected as the second mode. . For example, when the sensor operating in the first mode is a geomagnetic sensor and the geomagnetic sensor functions in the 2a mode, the setting information is information indicating that the 2a mode is selected as the second mode.
Alternatively, if the sensor being used during operation in the first mode is not included in the sensors that function in the 2a mode, the setting information is information indicating that the 2b mode is selected as the second mode. may be For example, if the sensor operating in the first mode is a geomagnetic sensor and the geomagnetic sensor does not function in the 2a mode, the setting information is information indicating that the 2b mode should be selected as the second mode.

The mode selection unit 114 selects the 2a mode or the 2b mode as the second mode based on the setting information acquired by the setting information acquisition unit 113 .

Specifically, the first data transmission/reception unit 116 receives sensor information sensed by the sensor unit 25 from the sub-microcomputer 20 and stores the received sensor information in the sensor information storage unit 141 sequentially.
Also, the first data transmission/reception unit 116 transmits the sensor information stored in the sensor information storage unit 141 to the sub-microcomputer 20 . For example, when the pedometer function using sensor information is used in both the first mode and the second mode, when stopping the first mode, the first data transmission/reception unit 116 counts the latest number of steps in the first mode. The sensor information shown is extracted from the sensor information storage unit 141 and transmitted to the sub-microcomputer 20 . As a result, even when the operation mode is switched from the first mode to the second mode, the number of steps is not reset and the number of steps can be counted continuously.

The used sensor setting unit 117 sets the sensor used during the operation in the first mode as the sensor to be used in the 2a mode or the 2b mode. For example, when the gyro sensor is being used in the first mode, the used sensor setting unit 117 sets the gyro sensor as the sensor to be used in the 2a mode.

The second program processing section 211 controls the entire sub-microcomputer 20 . For example, the second program processing unit 211 includes a second display control unit 212, a second mode switching unit 213, a second data transmission/reception unit 214, a sensor information acquisition unit 215, and a time information acquisition unit 216. to operate.

Further, the second display control unit 212 causes the first display unit 18 to display information from the sensor unit 25 acquired by the sensor information acquisition unit 215 described later in the second mode as a result of processing in the second mode, for example. display the sensor information of Also, the second display control section 212 may display a predetermined image on the first display section 18 . A predetermined image is, for example, a background image. Furthermore, the second display control unit 212 changes the background image to another image according to the user's button operation or the like via the second input unit 26 .

The second mode switching unit 213 switches the operation mode from the 2a mode or the 2b mode to the first mode. More specifically, the second mode switching unit 213 transmits an operation instruction in the first mode to the main microcomputer 10 and terminates the operation in the 2a mode or the 2b mode. Note that this operation instruction includes a sensing instruction by a sensor that functions in the first mode. Details of the operation mode switching process will be described later using a flowchart.

The second data transmission/reception unit 214 transmits data to the main microcomputer 10 and receives data from the main microcomputer 10 . Specifically, the second data transmission/reception unit 214 transmits sensor information from the sensor unit 25 acquired by the sensor information acquisition unit 215 described later to the main microcomputer 10 .
Also, the second data transmission/reception unit 214 transmits the sensor information stored in the sensor information storage unit 241 to the main microcomputer 10 . For example, when the pedometer function using sensor information is used in both the first mode and the second mode, when stopping the second mode, the second data transmission/reception unit 214 updates the latest number of steps in the second mode. Such sensor information is extracted from the sensor information storage unit 241 and transmitted to the main microcomputer 10 . As a result, even when the operation mode is switched from the second mode to the first mode, the number of steps can be continuously counted without being reset.
The second data transmission/reception unit 214 also receives an operation instruction in the 2a mode or the 2b mode from the main microcomputer 10 and stores the setting information included in the operation instruction in the setting information storage unit 242 .

The sensor information acquisition unit 215 acquires sensor information from the sensor unit 25 . In particular, the sensor information acquisition unit 215 acquires information other than time information from the sensor unit 25 . The sensor information acquisition unit 215 also stores the sensor information acquired from the sensor unit 25 in the sensor information storage unit 241 .

The time information acquisition unit 216 acquires time information from the second RTC unit 30 .

[Example of display screen]
FIG. 7 shows examples of display screens displayed in the 2a-th mode and the 2b-th mode.
In the example of FIG. 7, a screen example of "outdoor style" used by the user outdoors is shown as mode 2a, and a screen example of "everyday style" used by the user in daily life is shown as mode 2b.

As shown in the example of FIG. 7 , in “outdoor style”, a compass ring 271 , a barometer 272 , a time 273 and an altimeter 274 are displayed on the first display section 18 .
The compass ring 271 is a ring that indicates an orientation, and the orientation is calculated using sensor information from the geomagnetic sensor. In the example of FIG. 7, the direction composed of the three fragments indicates north.
The barometer 272 indicates the atmospheric pressure at the current position of the information processing device 1, and the atmospheric pressure is calculated using sensor information from the atmospheric pressure sensor.
