SCREEN TRANSFER CONTROL SYSTEM, COMPUTER-READABLE RECORDING MEDIUM, AND SCREEN TRANSFER CONTROL METHOD

摘要

A screen transfer control system includes a business device performing a business process, a mobile terminal, and a screen transfer control device converting a business screen of the business device to image data and sending the image data to the mobile terminal, the screen transfer control device converting the business screen to the image data on the basis of the drawing command, detecting a change in the cursor shape on the basis of cursor information included in the drawing command, and sending change information, when a change in the cursor shape is detected, to the mobile terminal, the mobile terminal displaying the image data from the screen transfer control device, determining whether the cursor shape is changed on the basis of the change information, and starting up a software keyboard when a screen touch that made the change in the cursor shape continues for a predetermined time.

主权项

1. A screen transfer control system comprising:
a business device configured to perform a business process; a mobile terminal configured to be used by a user as an input-output device of the business device; and a screen transfer control device configured to convert a business screen, which is output by the business device, to image data and that sends the image data to the mobile terminal, wherein the screen transfer control device includes
a receiving circuit that receives drawing command that is output in order for the business device to display the business screen on the mobile terminal,a first sending circuit that converts, on the basis of the drawing command received by the receiving circuit, the business screen to the image data and that sends the image data to the mobile terminal,a detecting circuit that detects a change in the cursor shape on the basis of cursor information that is included in the drawing command received by the receiving circuit, anda second sending circuit that sends, when a change in the cursor shape is detected by the detecting circuit, change information related to the change to the mobile terminal, and the mobile terminal includes
a displaying circuit that receives the image data sent by the first sending circuit and that displays the image data,a first determination circuit that determines, on the basis of the change information sent by the second sending circuit, whether the cursor shape is changed to the cursor shape for a character input,a second determination circuit that determines, when the first determination circuit determines that the cursor shape is changed to the cursor shape for the character input, whether a screen touch that made the change in the cursor shape continues for a predetermined time, anda startup circuit that starts up a software keyboard when the second determination circuit determines that the screen touch continues for the predetermined time.
