Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a touch panel device having an input assist function for a visually impaired person.
[0002]
[Prior art]
First of all, there is a problem that the conventional touch panel cannot be operated by visually impaired people, and as a solution to that problem, measures such as providing a transparent braille sheet or a perforated guide on the screen were considered, There is a drawback that it is a hindrance to the operation of ordinary people, and it is also structurally large. In addition, measures have been taken to provide guides and buttons with Braille symbols outside the screen, but there is a drawback that the screen is touched by mistake and the operation is erroneous.
[0003]
As a prior art example of a touch panel device conscious of the visually impaired in order to solve the above-mentioned problem, a functional area of a touch type input panel that performs input by regarding a part of the input portion as a button without having a specific input button When an operator touches, the operator first notifies the operator of the function assigned to the touched part by using the sound generation function, and at the same time touches a specific area of the panel to determine that the input is desired, so that even visually impaired persons can There is a “touch type input device control method” that can search for a function area to be input and perform input (see, for example, Patent Document 1). In addition, the mode is switched, and a plurality of fare displays corresponding to each boarding section displayed on the touch panel are provided with a button for shifting to a lower price and a button for shifting to a higher price. The desired boarding right can be selected and specified by voice guidance means that informs the fare guide corresponding to the amount by voice, and in the case of purchase decision, the visually impaired person can purchase the desired boarding ticket by pressing the ticket purchase button. There is a “touch panel type automatic ticket vending machine” (see, for example, Patent Document 2). In addition, when the touch panel is pressed, the operator is notified by voice of what the button at the pressed position is, and when the button pressed by the voice is pressed again, the selection of the button is confirmed. There is a “touch panel input device” (see, for example, Patent Document 3). In addition, an area for switching to the screen search mode is provided on a part of the touch panel, and when the user touches this area, the information input device and automatic transaction device that reads out and outputs what is the button at that location. (For example, see Patent Document 4).

[Problems to be solved by the invention]
However, in the invention described in Patent Document 1, when a part of the touch panel screen is used as a determination button, it is difficult for a visually impaired person to recognize the position, or an erroneous operation can be performed while touching the screen. In addition, there is a problem that the entire screen cannot be flexibly used because a part of the touch panel screen must always be used as a determination button.
[0006]
Further, the invention described in Patent Document 2 has a problem that it is necessary to operate the button many times before purchasing a desired ticket, and it takes time to listen to a voice reading accompanying the operation.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a touch panel device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[0018]
First, the configuration of the touch panel device according to the embodiment of the present invention will be described. FIG. 1 is a block diagram of a touch panel device according to an embodiment of the present invention. A touch panel controller 2 includes position information from a touch panel 1 on which an operator performs various input operations, touch information, and pressing information on a decision switch 5. Is entered. Here, the position information is information indicating the touched position on the screen, and the touch information is information for recognizing the touch. The pressing information is information indicating that the determination switch 5 has been pressed by the operator.
[0019]
The application software 3 is notified of position information and touch information when the operator touches the touch panel 1 from the touch panel controller 2, and pressing information when the operator presses the decision switch 5, and controls each means. .
[0020]
The speaker / headphone 4 performs operation guidance or the like by voice to the operator regarding the contents of buttons and keys on the touch panel under the control of the application software 3.
[0021]
The decision switch 5 is provided separately from the screen of the touch panel 1 and has a shape that can be easily recognized by a visually impaired person. The visually impaired person presses the decision switch 5 when he / she wants to decide the input after listening to the voice guidance of the speaker / headphone 4.
[0022]
Next, the operation of the embodiment of the present invention will be described with reference to FIG. First, the mode selection is performed by the operator operating the decision switch according to the voice guide, or the mode selection by detecting the wearing of the headphones in hardware, and the touch panel controller 2 is instructed by an instruction from the application software 3. Switching between the normal mode and the visually impaired person mode is performed (S1).
[0023]
When the normal mode is selected (S1 / NO), when the operator touches the touch panel 1 (S8 / YES), an event (hereinafter referred to as touch information) that the touch panel controller 2 touches the position information is referred to as the application software 3. (S6). The application software 3 performs processing based on the notified position information and touch information (S7).
[0024]
When the visually impaired person mode is selected (S1 / YES), when the operator touches the touch panel 1 (S2 / YES), only the position information is notified from the touch panel controller 2 to the application software 3 (S3). Here, the application software 3 is not notified of touch information indicating that the operator has touched the touch panel screen simply by touching the touch panel screen.
[0025]
The application software 3 guides information (screen information) such as buttons displayed on the screen corresponding to the notified position information to the operator by voice from the speaker / headphone 4 (S4). The operator listens to the voice guidance while touching the screen, and presses the determination switch 5 provided separately from the touch panel screen when the guidance of the button to be pressed is met (S5 / YES).
[0026]
When the determination switch 5 is pressed, the touch panel controller 2 notifies the application software 3 of touch information corresponding to the case where the screen is pressed in the normal mode (S6). Then, the application software 3 performs processing based on the previously notified position information and touch information (S7).
[0027]
As described above, according to the touch panel device according to the embodiment of the present invention, in the visually impaired person mode, no special touch panel operation by the operator is required, and the application only switches the mode in the device. It can be easily operated by visually impaired people with the same operation.
[0028]
