Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1, fig. 1 is a system block diagram of a capacitive touch device with adjustable sensitivity according to an embodiment of the present invention. The capacitive touch device 1 with adjustable sensitivity comprises a capacitive touch screen 11 with a pressure sensing function, a key assembly 12 and a control unit 13.
The capacitive touch screen 11 is used for displaying a user interface, and the capacitive touch screen 11 has a plurality of touch sensitivity modes. In practical applications, a pressure sensor is generally integrated in or under the display screen of the capacitive touch screen 11 with pressure sensing function for sensing the pressure of a touch point when the touch screen is touched. In addition, different touch senses can be adjusted by setting different detection sensitivities so as to correspond to a plurality of touch sensitivity modes.
The key assembly 12 is disposed adjacent to the capacitive touch screen 11, and the key assembly 12 is configured to send a pressing signal.
The control unit 13 is electrically connected to the capacitive touch screen 11 and the key assembly 13. When the capacitive touch screen 11 is in an activated display state and a pressure value of a touch point sensed by the capacitive touch screen 11 in the user interface display area 110 of the capacitive touch screen 11 is greater than a first preset threshold, the control unit 13 controls the capacitive touch screen 11 to display the sensitivity adjustment interface 111 and activates the touch sensitivity adjustment state; when the touch sensitivity adjustment state of the capacitive touch screen 11 is activated and the key assembly 12 is pressed, the control unit 13 controls the capacitive touch screen 11 to switch between the touch sensitivity modes according to the pressing signal of the key assembly 12.
In one embodiment, the sensitivity adjustment interface 111 is located within the user interface display area 110 of the capacitive touch screen 11; when the capacitive touch screen 11 is in the touch sensitivity adjustment activated state and the capacitive touch screen 11 is touched in a user interface display area outside the sensitivity adjustment interface 111, the control unit 13 controls the capacitive touch screen 11 to close the sensitivity adjustment interface 111 and exit the touch sensitivity adjustment state.
Preferably, the key assembly 12 may be a single physical key. For example, the key assembly 12 is a power key of the capacitive touch device 1. In practical applications, when the touch sensitivity adjustment state is activated and the key assembly 12 is pressed multiple times, the control unit 13 controls the capacitive touch screen 11 to cyclically switch between the multiple touch sensitivity modes according to multiple pressing signals of the key assembly 12.
Preferably, the key assembly 12 may include a first key and a second key, the first key is a volume increasing key of the capacitive touch device 1, and the second key is a volume decreasing key of the capacitive touch device 1.
In practical applications, when the touch sensitivity adjustment state is activated and the first key is pressed, the control unit 13 controls the capacitive touch screen 11 to switch between the touch sensitivity modes to the touch sensitivity mode with the increased touch sensitivity according to the first pressing signal of the key assembly 12. When the touch sensitivity adjustment state is activated and the second key is pressed, the control unit 13 controls the capacitive touch screen 11 to switch between the touch sensitivity modes to the mode with the decreased touch sensitivity according to the second pressing signal of the key assembly 12.
Referring to fig. 2 in combination, fig. 2 is a flowchart of a control method of a capacitive touch device according to an embodiment of the invention. Based on any one of the above embodiments of the capacitive touch device 1 with adjustable sensitivity, the capacitive touch device 1 includes a capacitive touch screen 11 with a pressure sensing function and a key assembly 12 disposed adjacent to the capacitive touch screen 11, the capacitive touch screen 11 is used for displaying a user interface, and the key assembly 12 is used for sending a pressing signal. The capacitive touch screen 11 has a plurality of touch sensitivity modes. The control method comprises the following steps:
s1, when the capacitive touch screen 11 is in the activated display state and the pressure value of the touch point sensed by the capacitive touch screen 11 in the user interface display area 110 of the capacitive touch screen 11 is greater than the first preset threshold, the capacitive touch screen 11 is controlled to display the sensitivity adjustment interface 111 and the touch sensitivity adjustment state is activated.
S2, when the touch sensitivity adjustment status of the capacitive touch screen 11 is activated and the key assembly 12 is pressed, controlling the capacitive touch screen 11 to switch between the touch sensitivity modes according to the pressing signal of the key assembly 12.
Preferably, the sensitivity adjustment interface 111 is located within the user interface display area 110 of the capacitive touch screen 11; when the capacitive touch screen 11 is in the touch sensitivity adjustment activated state and the capacitive touch screen 11 is touched in the user interface display area outside the sensitivity adjustment interface 111, the capacitive touch screen 11 is controlled to close the sensitivity adjustment interface 111 and exit the touch sensitivity adjustment state.
Aiming at different implementation modes, the invention can allow a user to set the operation mode of the physical key by himself to switch different operation settings. For example, when a key is pressed and held down, the first operation setting can be switched, and when two keys are pressed and held down, the second operation setting can be switched; meanwhile, when the operation settings are switched, a scroll bar appears on a display area of the user interface to display the operation settings for selecting the switching. In addition, the present invention is not necessarily implemented using one key, and switching between different operation settings may be implemented by a combination of a plurality of keys.
By the invention, when a user wears thick gloves, the sensitivity of the touch screen can be increased to provide better operation; however, the increased sensitivity may have other disadvantages so that the user may only wish to increase the sensitivity only temporarily in such a situation. The same scenario occurs when operating in water. In this case, the sensitivity of the touch screen needs to be adjusted down a little to ignore the effect of water on the touch screen, and likewise, the adjustment of the sensitivity may be only temporary.
The sensitivity-adjustable capacitive touch device and the control method thereof can temporarily adjust the touch screen to meet the use requirements under various extreme use situations, and can also be conveniently switched to the default conventional operation setting. The convenient selection mode switching fully utilizes the characteristics of the pressure sensing type capacitive screen, and through the use of the physical keys, a user can conveniently obtain different operation characteristics no matter what use environment the touch screen is in, so that the touch screen is convenient and is not easy to operate mistakenly.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
