Abstract

A plurality of mobile devices interoperate without configuration operation. A mobile device system including a plurality of mobile devices is provided. Each mobile device is operable in one of an independent-operation mode in which the mobile device operates with priority over the other mobile devices and a dependent mode in which the mobile device operates dependently on another mobile device and includes a control unit having a start-up-order detection unit configured to detect the start-up order of the mobile device with respect to the other mobile devices. A first mobile device operates in the independent-operation mode when the start-up order of the first mobile device detected by the start-up-order detection unit is earlier than the start-up order of a second mobile device and operates in the dependent-operation mode when the start-up order is later than the start-up order of the second mobile device.

Claims

1. A mobile device system comprising:

a plurality of mobile devices,

wherein each mobile device is operable in one of an independent-operation mode in which the mobile device operates with priority over the other mobile devices and a dependent mode in which the mobile device operates dependently on another mobile device and includes a start-up-order detection unit configured to detect the start-up order of the mobile device with respect to the other mobile devices, and

wherein a first mobile device operates in the independent-operation mode when the start-up order of the first mobile device detected by the start-up-order detection unit is earlier than the start-up order of a second mobile device and operates in the dependent-operation mode when the start-up order is later than the start-up order of the second mobile device.

2. The mobile device system according to claim 1,

wherein the mobile devices each include a display unit, and

wherein when the start-up order detected by the start-up-order detection unit of the first mobile device is later than the start-up order of the second mobile device, the content displayed on the second mobile device is displayed on the display unit of the first mobile device.

3. A mobile device comprising:

a start-up-order detection unit configured to detect the start-up order of the mobile device with respect to other mobile devices, wherein each mobile device is operable in one of an independent-operation mode in which the mobile device operates with priority over the other mobile devices and a dependent mode in which the mobile device operates dependently on another mobile device,

wherein a first mobile device operates in the independent-operation mode when the start-up order of the first mobile device detected by the start-up-order detection unit is earlier than the start-up order of a second mobile device and operates in the dependent-operation mode when the start-up order is later than the start-up order of the second mobile device.

4. The mobile device according to claim 3, further comprising:

a display unit,

wherein when the start-up order detected by the start-up-order detection unit of the first mobile device is later than the start-up order of the second mobile device, the content displayed on the second mobile device is displayed on the display unit of the first mobile device.
