Description

Terminal with touch input synchronization function and control method thereof

The present invention relates to a terminal having a touch input synchronization function and a control method thereof, and more particularly, to transmit and reflect a user touch input value sampled from a display terminal for synchronizing and outputting a screen transmitted from the portable terminal. A terminal having a touch input synchronization function and a control method thereof.

Recently, with the development of information and communication technology, the spread of smart phones is rapidly made. Smartphone is an intelligent terminal that adds various computer support functions including data communication functions such as internet communication and information retrieval to mobile phones, as well as functions such as GPS module, acceleration sensor, CPU, GPU, memory performance as high as desktop PC. Equipped with. However, smart phones have a small display device compared to information communication devices used in fixed locations such as desktop PCs and navigation in terms of portability.

The number of users who own high-end smartphones is increasing, and in the future, almost every user is expected to carry a smartphone. Therefore, most data processing is performed in a high-end smartphone, and a device (hereinafter, a display terminal) such as a navigation device mounted on a vehicle and used only in a fixed position receives the same image output from the smartphone screen and displays it on the screen. Attempts have been made to ensure that there are only minimum specifications to perform the function.

Meanwhile, the display terminal not only synchronizes and displays the screen transmitted from the portable terminal, but also transmits a user input touch value input through the touch panel provided to the portable terminal to reflect the touch input synchronization function to reflect the operation of the portable terminal. Can provide.

1 is a view provided to explain a normal touch input synchronization function.

When the user moves the finger to the touch panel of the display terminal while pressing the finger to remove the finger at another point, the user touch input value as illustrated in FIG. 1 may be sampled for the flicking operation. For example, the user touch input value may be sampled as touch down (■) at 0 seconds, sampled as touch move (●●●●) from 2 seconds to 4 seconds, and sampled as touch up (★) at 5 seconds. . Here, touch down (■) is a user touch input value that is sampled when the user brings a finger to the touch panel, and touch move (●) is a user touch input value that is sampled when the user moves the touch panel with a finger. The touch up (★) refers to a user touch input value sampled when a finger is removed from the touch panel.

After the user performs the flicking operation, if the touch input synchronization function is normally performed, the user terminal may transmit the user touch input values from the display terminal in the order of. Of course, the user's touch input value from the display terminal to the portable terminal may be delivered with a predetermined time delay in the process of being transmitted through local area communication such as Wi-Fi or Bluetooth. In FIG. 1, the delay time is illustrated as 1 second.

Even when the touch input values are delayed for a predetermined time, the user may feel that the operation according to the touch input is somewhat delayed. However, since the mobile terminal operates as the user intended, the problem due to the operation error does not occur.

Referring to FIG. 2, in the process of user touch input values being sampled at the display terminal at 1 second intervals and transmitted to the mobile terminal in the order of ●●●●● ★, the touch input values (●) sampled at 2 seconds at the display terminal. If the transmission is abnormally transmitted to the portable terminal every 3 seconds (TD), the mobile terminal may be misrecognized as a long press from 2 seconds to 5 seconds that the user touch input value is not transmitted is processed. In this case, there may be a problem that the mobile terminal performs a different operation from the touch input operation intended by the user in the display terminal.

3 is a view provided to explain another abnormal touch input synchronization operation.

Referring to FIG. 3, the user actually inputs touch input values on the display terminal in order of flicking, but in the display terminal as illustrated in FIG. 3. ● ★ may be mistaken. This malfunction may occur mainly when a touch input is performed using a finger in the pressure sensitive touch panel.

In this case, although the touch input value is normally transmitted from the display terminal to the portable terminal, since the touch input itself is misrecognized in the display terminal, there may be a problem in that the portable terminal performs a different operation from the user's intended touch input operation.

Accordingly, an object of the present invention is to provide a terminal having a touch input synchronization function and a control method thereof capable of accurately reflecting a user touch input value sampled by a display terminal to a portable terminal without error.
