Further, “2222” is issued as “ID” to “application B” corresponding to the application 74 of the mobile terminal 13B, and is associated with “desktop B”.

  As described above, in the present embodiment, it is possible to accept requests from a plurality of portable terminals 13 by issuing a specified ID for each application 74 and managing it in association with the desktop. In addition, since a desktop is prepared for each application 74, it is possible to project different screens to the plurality of image projection apparatuses 14, respectively.

<Network projector startup processing>
Next, processing until the network projector 33 is activated by the network projector control unit 35 of the information processing apparatus 11 described above will be described. FIG. 8 is a flowchart showing the flow of the network projector activation process.

  As shown in FIG. 8, when the network projector control unit 35 receives a projector projection start request from the application 74 of the mobile terminal 13 via the command transmission / reception unit 34 (S40), the network projector control unit 35 issues a projection start request based on the IP address information. It is determined whether the image projection apparatus 14 that has been used is in use (S41).

  Here, if the network projector control unit 35 determines that the image projection device 14 that is the target of the projection start request is not in use (NO in S41), the network projector control unit 35 has already referred to the management table in FIG. It is determined whether an ID is issued (S42).

  If it is determined that the ID has already been issued (YES in S42), the network projector control unit 35 creates a new desktop (virtual desktop) (S43) and issues a new ID (S44). For example, in FIG. 7, since “1111” is issued as “ID” to “application A”, “desktop B” is created for “application B” and “2222” is set as “ID”. This is the case when it is issued.

  On the other hand, when it is determined that the ID has not already been issued (NO in S42), network projector control unit 35 executes the process of S44. For example, in FIG. 7, since “ID” has not been issued to any application 74, the requested application 74 is “application A”, “1111” is issued to “ID”, and “desktop A” "Is assigned.

  After the processing of S44, the network projector control unit 35 requests the application unit 37 to start an application such as a PowerPoint file (S45). For example, when the requested application 74 is “application A” described above, the network projector control unit 35 activates the application by the application unit 37A of “desktop A”.

  Next, the network projector control unit 35 activates the network projector 33 (S46). For example, when the requested application 74 is “application A”, the “desktop A” is displayed and the processing is terminated. To do.

  Note that the network projector control unit 35 terminates the process as it is because the image projection device 14 that is the target of the projection start request is in use (YES in S41) because it cannot be used.

<Example of key event corresponding to operation input command>
Next, an operation input command received by the command transmission / reception unit 34 of the information processing apparatus 11 and a key event issued by the key event issuing unit 36 will be described. FIG. 9 is a diagram illustrating an example of a key event corresponding to an operation input command.

  In the example of FIG. 9, “operation”, “operation input command”, “issued key event”, “corresponding key”, “processing content”, and the like are associated with each other. Here, “operation” indicates, for example, a user operation executed on the display panel 72 of the mobile terminal 13, and “operation input command” indicates the command transmission / reception unit 34 of the information processing apparatus 11 from the application 74 of the mobile terminal 13. Indicates the command to be notified.

  The “issued key event” indicates an event issued by the key event issuing unit 36 in response to a command received by the command transmitting / receiving unit 34 in the information processing apparatus 11. The “corresponding key” indicates a key corresponding to a keyboard such as a PC, for example. Indicates what is to be done.

  As shown in FIG. 9, for example, in the case of “operation” on the mobile terminal 13, when the display panel 72 is touched (“touch panel touch”), the application 74 of the mobile terminal 13 sends the command transmission / reception unit 34 of the information processing apparatus 11. “RIGHT” is notified as “operation input command”.

  In this case, “RIGHT” is issued as a key event by the key event issuing unit 36 in the information processing apparatus 11, and “→” is assigned as “corresponding key”. As a “processing content” corresponding to “,” control is performed so that “animation advances” for a predetermined file. As a result, for example, the image projection device 14 projects a predetermined file with an advanced animation.
