Is an exemplary view in which an info key region is selected.

In the present invention, the target layer may be registered using a double tap or a long touch, and in FIG. 3, the double tap will be described for convenience of description.

As shown in FIG. 3, in the present invention, a voice over mode for outputting guide information corresponding to an operation of the touch screen 100 as a voice is set as a default (S301).

In the voice guidance mode (S301), when the normal key region 102 is selected as shown in FIG. 4 (S302), the voice guidance mode is terminated (S303).

In FIG. 3, the normal key area 102 is selected in step S302, but the step of selecting the normal key area 102 may be performed in any of steps S302 to S314, and the normal key area 102 may be selected. If selected, the control unit 200 does not output a control signal to the voice output unit 300 for a set first time. Then, the voice output unit 200 does not perform voice guidance for the set first time. However, when the first time elapses, the controller 200 returns to the voice guidance mode.

In this case, the first time is a time required for the normal key region 102 to be selected and the selection of the target layer to be completed.

If the normal key area 102 is not selected (S302), the voice guidance mode continues.

In the voice guidance mode, when the touch area is recognized in the touch screen 100 (S304), the controller 200 determines whether the touch area is a simple touch included in one key area or a multi touch included in a plurality of key areas. (S305).

As shown in FIG. 5, when the touch area is a multi-layer touch included in at least two or more key areas (S306), the controller 200 outputs a control signal indicating that two or more key areas are selected. 300).

Then, the voice output unit 300 outputs, as voice, guide information indicating that multiple layers have been touched, such as "Please register using multiple fingers, as multiple layers may be registered" (S307).

In this case, the voice output unit 300 may output the information of the currently touched layer, for example, the numbers of the 4th, 6th, 9th and 10th floors as voice.

As shown in FIG. 6, when the touch area corresponds to a boundary between two key areas (S308), the controller 200 sends a control signal to the voice output unit 300 indicating that the boundary between two key areas is selected. Output

Then, the voice output unit 300 outputs voice guidance information indicating that the floor boundary is selected, such as "the boundary between the 9th and 10th floors. Please move to the side" (S309).

However, as shown in FIG. 7, when the touch area corresponds to a simple touch included in one key area, the controller 200 outputs a control signal to the voice output unit 300 to output information about one key area. .

Then, the voice output unit 300 outputs the floor number as voice, such as "9th floor". At the same time, the voice output unit 300 may output guide information, "double tap to register" (S310).

In this case, the voice output unit 300 may output guide information "press and hold to register".

As shown in FIG. 8, when a double tap long touch (touch for a set third time) is recognized (S311), the controller 200 registers a layer corresponding to the double tap or the long touched key area as the destination layer. The control signal indicating that the floor is registered is output to the voice output unit 300 (S312).

Then, the voice output unit 300 outputs the target floor notification guide information, such as "9th floor has been registered as the target floor."

At this time, the double tap should be recognized within the set second time. The second time is generally the time it takes for people to click twice on the touch screen 100 consecutively, which can be changed.

In addition, the long touch must be continuously recognized for the set third time. The third time is generally longer than the average time required for a person to touch the touch screen 100 once. In the present invention, the third time is set to the same time as the second time for convenience of design, but the third time is May be changed to a time different from the second time.

After the target layer is registered, when the target layer is touched (S313), the controller 200 outputs a control signal to the voice output unit 300 to output information about the target layer and the method of canceling the target layer.

Then, the audio output unit 300 outputs guide information on the target floor and the target floor termination method, such as "double tap to cancel the 9th floor" or "touch the 9th floor to cancel the 9th floor" ( S314).

 In this case, when a double tap or a long touch is recognized with respect to a key area corresponding to the target layer (S315), the controller 200 outputs a control signal indicating the termination of the target layer to the voice output unit 300.

Then, the voice output unit 300 outputs the guide information for the termination of the target layer (S316).

Although not shown in FIG. 3, in any of steps S301 to S316, the step of selecting the info key area 103 may be performed as shown in FIG. 10. When the info key region 103 is selected, the controller 200 outputs a control signal for outputting the touch screen operation method to the voice output unit 300, and the voice output unit 300 outputs the touch screen operation method as voice. do.

As described above, according to the present invention, the visually impaired person can easily manipulate the touch screen by outputting information according to whether the touch area where the user touches the touch screen 100 is a simple touch or a multi touch. By providing floor guidance information for the key area, the user can more easily find and register the destination floor.

In addition, in the present invention, by registering a target floor using a double tap or a long touch, a blind person can easily register the target floor by a simple hand gesture.

In addition, in the present invention, when the general user selects the normal key region, the voice guidance is stopped, and when a predetermined time elapses, the voice guidance mode is returned to the voice guidance mode, thereby providing the voice guidance mode and the voice guidance termination mode according to the user.

In the present invention, the guide information may provide not only the number of floors but also other information such as building information and store information included in the floor.
