Embodiment Construction

[0051] figure 2 is a block diagram of an electronic device according to an embodiment of the present invention. see figure 2, the electronic device 200 includes a touch screen 210 , a first camera unit 220 , a face position acquisition module 230 , and a touch position correction module 240 .

[0052] The touch screen 210 is, for example, a resistive touch screen or a capacitive touch screen, and the present invention does not limit the type of the touch screen 210 . The touch screen 210 detects a user's touch through a touch sensing layer having a touch sensing element, and presents various images through a display medium layer such as liquid crystal. In this embodiment, the controller of the touch screen 210 converts each touch into two-dimensional touch coordinates including X-axis coordinates and Y-axis coordinates.

[0053] The first camera unit 220 may be a camera or a video camera for shooting a first image. In this embodiment, the first camera unit 220 and the to...

Abstract

An electronic device and a method for correcting a touch position of the electronic device. The electronic device comprises a touch screen and a first camera unit. The method comprises the steps of: taking a first image through the first camera unit, and performing human-face detection processing for the first image to determine human-face position information; calculating a coordinate offset according to the human-face position information; and correcting a two-dimensional touch coordinate which is detected by the touch screen and corresponding to the touch by utilizing the coordinate offset.

Description

technical field [0001] The present invention relates to a touch operation technology, and in particular to a method for correcting a touch position and an electronic device using the method. Background technique [0002] With the advancement of touch technology, touch screens gradually replace traditional screens as input and output tools for electronic devices. Many consumer electronic products also use touch screens to save the space of physical keys in order to meet the requirements of users for light and compact appearance, and use a larger area to place large-sized touch screens. [0003] figure 1 It is a schematic diagram of light refraction when the user is positioned at different positions in front of the touch screen. like figure 1 As shown, a general touch screen includes a touch sensing layer 110 for detecting touch operations, a substrate 120 made of glass, plastic or acrylic, and a liquid crystal (liquid crystal) display medium layer 130 that can emit light. ...
