Embodiment 1

[0022] A touch screen device that realizes various gesture operations according to an embodiment of the present invention, such as figure 1 As shown, it includes a gesture receiving unit, a gesture recognition unit, an operation object selection unit, and an operation command execution unit; wherein the gesture reception unit is connected with the gesture recognition unit, the operation object selection unit is connected with the gesture recognition unit, and the operation command execution unit is connected with the gesture recognition unit respectively. The gesture recognition unit is connected to the operation object selection unit.

[0023] The gesture receiving unit is used to receive the gesture of the user; the gesture recognition unit is connected to the gesture receiving unit and is used to identify the user's gesture operation type and gesture selection; the operation object selection unit is connected to the gesture recognition unit and is used to select The gesture...

Embodiment 2

[0038] The device in this embodiment is the same as the device in the embodiment, and this embodiment provides the fist erasing gesture and the hand back erasing gesture.

[0039] When editing electronic documents on the touch screen, electronic documents include: notepad, office application software, memo, chat tools and other text input and graphics input, fist erase gesture, make your hand into a fist shape, and use the bottom of the fist to place On the strokes that need to be erased, move the fist in the way of wiping the blackboard to erase the strokes; the gesture receiving unit first receives the pattern at the bottom of the fist, then the gesture recognition unit recognizes the gesture as a fist erasing gesture, and finally the operation command execution unit connects the gestures The recognition unit and the operation object selection unit perform an erasing operation.

[0040] Back of hand erasing gesture, four fingers together, and then put the back of the four fi...

Abstract

The invention discloses a touch screen or white board achieving various gesture operations, and belongs to the technical field of touch control. In the prior art, gesture operations of a touch screen are simple, the touch screen has few functions, and the operations are tedious and consume long time. The touch screen comprises a gesture receiving unit, a gesture recognition unit, an operand selection unit and an operation command execution unit. The gesture recognition unit is used for recognizing a gesture operation of two vertical or horizontal straight lines in the electronic document editing process to indicate a copying or pasting operation, and the threshold range can be set, for example, the distance between the two straight lines is set to be smaller than 300 pixels; if the length of the straight lines is set to be larger than 400 pixels, it is determined that the gesture operation is the copying or pasting operation. The gesture recognition unit is used for recognizing the gesture operation of closing four fingers or a gesture operation conducted at the bottom of a fist in the electronic document editing process to indicate an erasing operation. The touch screen is convenient and natural to operate.

Description

technical field [0001] The invention belongs to the technical field of touch screens, and more particularly relates to a touch screen for realizing multiple gesture operations. Background technique [0002] At present, touch screens are generally used in many electronic devices and systems for display and input operations. Users can interact with touch screens through user interfaces including user interface objects. Touch screen devices detect and respond to contacts on the touch screens. Users can use a A finger, multiple fingers (multi-touch gestures) or a stylus touch the touchscreen at a location corresponding to the user interface object the user wants to interact with to activate functions and trigger processes. [0003] It is more convenient and natural for users to edit electronic documents by using gesture operation methods; while when operating a terminal, users often hope that there are more types of gesture operations and more powerful functions, and finally rea...
