Problems solved by technology

[0004] However, since the touch panel of the touch screen has a certain thickness, as the user's viewing posture and angle are different, parallax will be generated when the user's eyes watch the target displayed under the touch panel.
This parallax will cause when the user touches the target with the finger, there will be a gap between the touch position of the finger and the display position of the target, so that the target cannot be touched correctly
Especially for some applications executed on electronic devices, due to design considerations, the size of icons or buttons on the operation interface may be too small, which also increases the difficulty for users to touch

Embodiment Construction

[0036] Observing the general user's touch operation behavior, it can be found that whenever the user does not touch the target to be operated, the user will continue to try to touch the same target until the target is touched. All the touches of the user before the successful touch can actually be used as a reference for judging the user's touch habit, and can be further used to adjust the range of the target that the user can touch. Therefore, the present invention analyzes the user's continuous touch behavior on the same target, and appropriately extends the touchable range of the target according to the distribution of touch points, so that the user can touch the target more accurately in subsequent operations. The target to operate on.

[0037] figure 1 It is a schematic diagram of an electronic device performing touch detection according to an embodiment of the present invention. Please refer to figure 1 , the electronic device 10 of this embodiment uses the touch scre...

Abstract

The invention provides a method and a device for touch detection. The method comprises: receiving multiple touch points detected on a touch screen, thereby detecting a foreground program used at present, and inquiring a database to acquire at least one touch object on the operation interface of the foreground program and the original range for touching each touch object. Then whether multiple touch points touched continuously among the touch points are located in the original range of one of the touch objects or not is determined. When one or more touch points are located in the original range of one of the touch objects, according to the location of other touch points, the extension range of the touch object to be touched subsequently is determined.

Description

technical field [0001] The present invention relates to a touch detection method and device, and in particular to a touch detection method and device capable of learning user's operating habits. Background technique [0002] Compared with the traditional keyboard input method, the operation method of the touch screen has simple and intuitive advantages, so today's consumer electronics products such as mobile phones, personal digital assistants, and tablet computers, and even notebook computers, desktop computers, and various household appliances, are available. The trend of using a touch screen instead of a traditional keyboard as an input interface. [0003] In the traditional keyboard input method, the user must tap the keyboard while comparing the images displayed on the screen to successfully complete operations such as text input or menu switching. And if the operation mode of the touch screen is adopted, the user can easily operate various functions of the electronic ...
