This input device 10 for the communication card 90 and the touchpad 33 further comprises a processor 31, a memory 32 (for storing a system program, a software control program, audio data, etc.), a play/record switch 38, and a power switch 39. The play/record switch 38 is used to switch between a play function and a record function, so that the user may hear sounds from the speaker 34 by pressing the communication card 90, as well as record sounds into the memory 32 via the microphone 37 by pressing upon the communication card 90. In this embodiment, a swappable memory module 32a (such as an SD card, a CF card or the like) and a memory slot 23 are provided; the swappable memory module 32a may store related software control commands or audio data for the plurality of communication cards 90. Therefore, a set of communication cards 90 may have a corresponding swappable memory module 32a.
The casing 20 has a clip 22, which can neatly clip together the plurality of communication cards 90, so that the user may go through the communication cards 90 by placing them on the control panel. The above-mentioned structure and functionality are disclosed in U.S. Pat. No. 6,369,721, and do needs no further description.
An objective of the present invention is to inform the user to turn to a particular communication card 90, and if the user turns to the wrong page he or she will be informed of that. In order to achieve the above mentioned objective, the embodiment of the present invention further comprises a target page reminding device 35 and a recognition device 36. Please refer to
In this embodiment, there are nine communication cards 90. Each communication card 90 has a corresponding page code; for example, these page codes may be 0 (the Home page), 1, 2 . . . 8. Use of the communication cards 90 typically begins with page 0 (the Home page). In order to simplify the following description, in the following, “target page code” indicates a correct page number; for example, at the very beginning of use, the “target page code”=page 0 (the Home page).
The target page reminding device 35 is used to remind the user to turn to the target page code. The target page reminding device 35 in this embodiment is a target page reminding display 35a; for example, the target page reminding display 35a displays the page code using a 7 segment LED. Therefore, the target page reminding display 35a displays “0” at the beginning of use. The target page reminding device 35 may also utilize the speaker 34 to inform the user of the correct communication card 90 by way of an audible sound; therefore, there may be no need for the target page reminding display 35a.
In this embodiment, most of communication cards 90 include a page code tag 92; for example, for the communication card 90 for page 0 (the Home page (FIG. 5A)), the page code tag 92 is printed with a “1”; the communication card 90 for page 4 (
The touchpad 33 receives a touch signal.
For example, the communication card 90 of page 0 (the Home page,
The technology utilized by the communication block 95 is a well known technology, and so needs no further description. However, the prior art input device does not have additional target page code information.
Checking to determine whether the current communication card 90 is correct.
For example, when the device is turned on, the “target page code” is page 0 (the Home page), and the recognition device 36 detects whether the current displayed communication card is page 0 (the Home page). The recognition device 36 can be, for example, eight light detectors, to detect whether the page code tag 92 of each communication card 90 has covered any of the eight light detectors to identify the current communication card 90. In this embodiment, all eight page code tags 92 separately correspond to the position of the eight light detectors (as shown in
The recognition device 36 can therefore detect the current displayed communication card 90 to obtain the corresponding page code of the communication card 90 for comparison with the “target page code”.
For example, if the “target page code” is page 0 (the Home page), and the current displayed communication card 90 is also page 0 (the Home page), step 404 is executed. But if the current displayed communication card 90 is not page 0 (the Home page), step 403 is executed.
Generating an error signal 31b.
For example, if the “target page code” is page 0 (the Home page), but the current displayed communication card 90 is not page 0 (the Home page), the processor 31 generates an error signal 31b. Then, the speaker 34 generates an error audio signal according to the error signal 31b. The error audio signal may be a pre-recorded in the memory 32, such as “please turn to page 0”, indicating that the page code of the current displayed communication card 90 is not the “target page code,” thus reminding the user to turn to the “target page code”.
Of course, the target page reminding display 35a may also generate an error information signal according to the error signal 31b. For example, the target page reminding display 35a may repetitively flash “Incorrect! Go to page 0”. The target page reminding display 35a may utilize an LCD or LED capable of displaying letters.
Since the currently-displayed communication card 90 is not the communication card 90 corresponding to the “target page code”, step 404 is not executed, and the currently-displayed communication card cannot be used, so that the user can not use the currently displayed communication card in a normal manner.
Executing the corresponding command.
If, for example, the user presses communication block 95 for “fruit” on the communication card 90 for page 0 (the Home page), with reference to
Determining whether there is a “target page code” command
By way of example, if the user presses communication block 95 for “fruit” on the communication card 90 of page 0 (the Home page), and with reference to
For example, if the user presses communication block 95 for “fruit” on the communication card 90 of page 0 (the Home page), “target page code” changes from “0” to “4”, and the processor 31 generates a target page code signal 31a (for example, with information about page code “4”) to cause the target page reminding device 35 to remind the user to turn to the corresponding communication card based upon the target page code signal 31a; for example, the target page reminding display 35a may display “4”.
The following provides further explanation of the operational principles of the input device 10.
Please refer to
If the user presses the communication block 95 for “apple” which is located in (X4-1LY4-1L˜X4-1RY4-1R) since the communication card 90 for page 4 matches the current “target page code”, step 404 is executed (playing the audio file Audio-4-1, such as pronouncing “apple” in English). Also, because the communication block 95 for “apple” has no corresponding target page code command, step 406 is not executed, which means the “target page code” remains “4”.
But, if the user presses the communication block 95 for “Home page” which is in (X4-8LY4-8L˜X4-8RY4-8R), since the corresponding target page code command of the communication block 95 for “Home page” is “go to page 0”, step 406 is executed, and the new “target page code” is “0”. Therefore, the target page reminding display 35a displays “0”, and the user should turn to the communication card 90 for the “Home page”.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
