2, the apparatus for recognizing a touch speed according to the first embodiment of the present invention includes a display unit 100, a sensing module 200, a controller 300, and a storage unit 400.

The display unit 100 may include a display device such as a liquid crystal display (LCD) or a light emitting diode (LED). Here, the display device visually provides various information defined according to the use purpose.

The sensing module 200 includes a front sensor 210 and a rear sensor 220 for sensing a touching unit contacting the display unit 100 and calculating an approaching speed of the touching unit.

As shown in FIG. 3, the front sensor 210 includes a front light emitting device 212 and a front light receiving device (not shown), which are installed to be spaced apart from the display unit 100 by a predetermined distance. do. In this case, the front light emitting element 212 and the front light receiving element are composed of a front light emitting element array and a front light receiving element array in which a plurality of elements are arranged, and the front light emitting element array and the front light receiving element array are connected to the display portion 100 And the number and arrangement of the front light emitting elements 212 and the front light receiving elements constituting the front light emitting element array correspond to each other.

That is, the light emitted from the front light-emitting element array is received by the front light-receiving element array, and when the touching means passes the light-emitting surface formed by the front light-emitting element array, The optical signal is interrupted. Whereby the passage time and position (x-axis or y-axis) of the touching means can be sensed.

The rear sensor 220 may include a rear light emitting element array and a rear light receiving element array in the same manner as the front sensor 210. The rear sensor 220 may include a rear light emitting element array, (L), and is installed so that the light irradiation direction of the front sensor 210 is perpendicular to each other.

 3, when the front sensor 210 is installed at the upper and lower ends of the display unit 100, the front sensor 210 senses the touch of the touch unit and detects the x-axis touch coordinates and the front sensor 210 The detected x-axis detection time t1 is calculated.

At this time, the x-axis touch coordinates and the x-axis sensing time calculated by the front sensor 210 are stored in the storage unit 400.

When the touching means passes through the light irradiation surface of the front sensor and passes through the light irradiation surface of the rear sensor, the rear sensor 220 senses the touch of the touching means and detects the y-axis touch coordinates and the rear sensor 220 Axis detection time t2 detected by the y-axis detection time t2. At this time, the y-axis touch coordinates and y-axis sensing time calculated by the rear sensor 220 are also stored in the storage unit 400.

Here, the detection times may be measured in units of second, but it is preferable to measure in units of milliseconds in order to increase measurement accuracy.

In the meantime, although the front sensor 210 is configured as an x-axis and the rear sensor 220 is configured as a y-axis for the sake of convenience, the sensing module 200 according to the first embodiment of the present invention includes a front sensor 210 the y-axis, and the rear sensor 220 may be configured as an x-axis.

The control unit 300 calculates input coordinates (x, y) and input speed of the touch means measured from the front sensor 210 and the rear sensor 220, and performs an emotion input command through the calculation. At this time, the input coordinates refer to the position information represented by the x-axis and y-axis coordinates calculated by the front sensor 210 and the rear sensor 220.

The calculation of the input speed can be calculated from the following mathematical expression 1.

Here, | t2-t2 | is the time that the touch means passes through the front sensor and the rear sensor, and the molecule is the separation distance (L) between the front sensor and the rear sensor.

Meanwhile, the emotional input command refers to an input command considering a touch speed in an input command that considers only a conventional planar touch position, and can be variously applied according to the type of the input command.

For example, when the input command is a command to input display contents on the screen, the thickness of the input display line may be set differently according to the input speed.

When the input command is a command for executing a specific function, the execution speed, execution amount, and the like of the command may be set differently according to the input speed.

Meanwhile, the storage unit 400 stores data and programs necessary for the operation of the emotional touch input device and the input method reflecting the touch speed according to the present invention.

3, the front sensor 210 and the rear sensor 220 are provided on a bracket 230. The front sensor 210 and the rear sensor 220 are disposed on a bracket 230, So as to be fixed on the front surface of the display unit 100.

Here, the front light emitting element 212 and the rear light emitting element 222 are arranged on an axis perpendicular to each other, and the front light receiving element and the rear light receiving element are also opposed to the front light emitting element 212 and the back light emitting element 222 They are disposed on the axis perpendicular to each other.

For example, when the front light emitting element 212 is disposed on the x-axis, the rear light emitting element 222 is disposed on the y-axis, and when the front light emitting element 212 is disposed on the y- The light emitting element 222 is disposed on the x-axis.

The distance L between the front light emitting device 212 and the back light emitting device 222 is the same as the distance L between the front light emitting device 212 and the back light emitting device 222. That is, And the distance from the back light emitting element 222 to the emitted light.

Hereinafter, an interface method according to a first embodiment of a touch-speed recognition interface device according to the present invention will be described in detail with reference to FIG.

As shown in FIG. 4, the touch speed recognition interface method starts with the front sensor 210 sensing the approach of the touch means (S110).

If it is determined in step 110 that the front sensor 210 has sensed the passage of the touching means, the touch coordinate and x-axis sensing time t1 of the x-axis sensed by the front sensor 210 are calculated (S120).

Next, it is determined whether the passage of the touching means is sensed by the rear sensor 220 (S130).

If the back sensor 220 senses the passage of the touching means as a result of the determination in operation 130, the touch coordinates and the y-axis sensing time t2 of the y-axis sensed by the rear sensor 220 are calculated (S140).

Next, the control unit 300 calculates input coordinates (S150). At this time, the input coordinates are composed of the touch coordinates of the x-axis calculated by the front sensor 210 and the y-axis coordinates of the y-axis calculated by the rear sensor 220. Here, the input coordinates indicate an arbitrary point of the display unit 100 that the user has touched to operate the interface.

Next, the control unit 300 calculates the input speed (S160). At this time, the input speed is calculated using the equation (1) using the x-axis sensing time t1 calculated by the front sensor 210 and the y-axis sensing time t2 calculated by the rear sensor 220 can do. The input speed may be calculated by reflecting the difference between the x-axis sensing time t1 at the y-axis sensing time t2 and the separation distance L between the front sensor 210 and the rear sensor 220. [

Next, the control unit 300 executes a sensible input command reflecting the input speed (S170). At this time, the emotional input instruction execution means operating the user interface according to the input speed.

If it is determined in step 130 that the rear sensor 220 does not detect the passage of the touch unit after the front sensor 210 senses passage of the touch unit, It is determined whether the sensing of the touch sensor of the front sensor 210 is terminated (S180).

If it is determined in step 180 that the sensing of the touch sensor of the front sensor 210 is terminated, the sensing process of the input command is terminated and a new input command is input. The detection of the touching means of the rear sensor 220 is awaited.

For example, when the user hesitates to touch input after passing through the optical surface of the front sensor 210 through the touching means, the front sensor 210 detects the x-axis touch coordinates And the x-axis detection time is continuously calculated. If the user abandons the input and is out of the sensing range of the front sensor 210, the calculation of the x-axis touch coordinates and the x-axis sensing time is stopped to end detection of the front sensor, When the touch input is completed through the light irradiation surface, the emotional input command is executed.
