[0029]
Examples of portable terminals include bar code readers, two-dimensional code readers, and examples of external devices include mobile phones with internet connection / browsing functions.
[0030]
FIG. 2 is a diagram illustrating an embodiment of a display unit provided in an external device of the mobile terminal system. The display unit 17 displays information provided from the server. In this example, the user ID, the product code, the quantity of the product input from the keyboard 16 and the name of the person in charge included in the optical information such as the barcode are displayed and displayed on these display units. A “Send” key and a “Cancel” key are displayed for instructing whether to confirm the information and send it to the server, or to cancel the work. Note that the quantity of merchandise and the name of the person in charge can also be included in the optical information 11 and transmitted from the mobile terminal 10 to the external device 19.
[0031]
FIG. 3 shows an example of a bar code representing a user ID. In this embodiment, the bar code is surrounded by a “decision” key, which is indicated by ABCDEF and determines the user's name or name or identification code information, and thereafter. Arrow key information for instructing the movement of the cursor to the product code window located under the user ID input window of the display unit 17 is included.
[0032]
FIG. 4 shows an example of a bar code representing a product code, which is surrounded by a “decision” key for determining product code information, which is indicated by 123 in the present embodiment, and then the product code on the display unit 17. Arrow key information for instructing movement of the cursor is included in the quantity window located below the input window.
[0033]
FIG. 5 is an embodiment of an optical information conversion table. An example of the optical information is a bar code. In the ASCII code 00h to 7Fh characters that can be expressed by this bar code, keys of external devices are mainly assigned to 00h to 1Fh. Here, an example of assigning a cellular phone key is shown.
[0034]
Here, it is assumed that a key operation desired to be realized on a mobile phone when a barcode is created is a barcode. A barcode reader, which is an example of a portable terminal, reads this barcode and transmits it to the cellular phone. In the transmitted mobile phone, the key operation information included in the barcode is realized in the same manner as the input from the keyboard of the external device. That is, when the upper Upper digit is 0 and the Lower digit is 1, the information is used to move the cursor to the left.
[0035]
In the conversion table shown in FIG. 5, the characters displayed as WAIT1 to WAIT5 indicate that the transmission waits until the data transmitted immediately before and the next data are transmitted. This is provided to prohibit keyboard input while the mobile phone is accessing data to the server. When the maximum value of the input prohibition time can be determined in the system to be realized, continuous data can be transmitted by including WAIT information in the barcode.
[0036]
FIG. 6 is a flowchart showing the operation of the portable terminal at the time of optical information reading using the optical information character conversion table shown in FIG. The characters shown in FIG. 5 can be mainly divided into mobile phone operation codes arranged at 00h to 1Fh of the ASCII code and data such as alphanumeric characters and symbols. In the portable terminal, these operation codes and data are discriminated at the time of transmission.
[0037]
By this operation, the operation information included in the barcode is converted into an operation code and transmitted to the mobile phone, and the operation can be realized on the mobile phone.
[0038]
The user inputs necessary data according to the input items displayed on the display unit. Here, for convenience, it is assumed that the position designation display portion when the screen is displayed is at the head of the input item A. Further, in order to start inputting data, an operation such as pressing the “OK” key is required from a keyboard provided in the external device.
[0039]
In the conventional system, the user inputs the user ID requested by the input item A from the keyboard of an external device represented by a mobile phone with Internet connection / browsing function.
[0040]
In addition, after a data item such as a user ID is input to the input item A using a keyboard of an external device, the position designation display unit needs to be moved to the input item B using the keyboard. Data items such as product codes required for the input item B are input by a portable terminal represented by a barcode reader or the like. After the input, the position designation display unit is moved to the input item C by the keyboard. As described above, in a system using a conventional portable terminal, the user needs to operate both the portable terminal and the external device, and there are problems such as poor work efficiency and complicated operation.
[0041]
Here, the optical information includes data of “decision”, “A” “B” “C” “D” “E” “F”, “decision”, and “↓”. The data actually transmitted to the server is the characters “A”, “B”, “C”, “D”, “E”, and “F”, but before and after that, “decision” and “↓” for operating the external device Contains information. The portable terminal converts this data into a command signal suitable for the external device and transmits it to the external device.
[0042]
As a result, the input item A can be input only by detecting the optical information by the portable terminal. Further, since the optical information includes information for moving the position designation display unit represented by the cursor or the like, the cursor moves to the input item B after the data is input. In this example, the user ID is input by reading the optical information. However, it is also possible to store the user ID, password, etc. in a storage device inside the portable terminal and transmit the data to an external device. Thereafter, data input and cursor movement can be similarly performed by detecting optical information with a portable terminal.
[0043]
When the input items A, B, C, and D are completed, the position designation display portion is on the send button. When the user confirms the contents of input data and transmits data to the server, the user can transmit data to the server by detecting optical information including “decision” information.
[0044]
In addition, at any time during data entry, the position designation display section can be canceled by detecting optical information including movement information of the position designation display section for the purpose of correcting errors in optical information to be detected and input errors. The input data of the input items A, B, C, and D can be canceled by moving to and “deciding”.
[0045]
Further, as represented by the above example, the system user can use the system only by detecting optical information with a portable terminal. Here, an example of data input on the screen is shown, but information such as the procedure for connecting to the server, switching of the input character type, and operation of the external device is included as optical information, and the key of the external device is detected by the mobile terminal It is possible to obtain the same effect as the operation.
According to the above embodiment, a portable terminal that converts optical information into a command signal suitable for the device can be provided. For example, a barcode reader connected to a mobile phone with internet connection / browsing function reads a barcode containing information for moving the position designation display section displayed on the screen of the device to a specific position, and places the position designation display section at a specific position. It is possible to move to.
Further, it is possible to provide a portable terminal that converts optical information into a command signal suitable for the external device. For example, a bar code reader connected to a mobile phone with internet connection / browsing function may be used to specify a specific position displayed on the screen of the mobile phone, and a position specifying display unit represented by a cursor may be generated there. it can.
[0046]
Further, the present embodiment is realized by a program, and can be easily implemented by another independent computer system by recording it on a recording medium such as a floppy disk and transferring it. FIG. 7 is a diagram for explaining a case where this is implemented with a floppy disk.
