Description
Technical Field
The invention relates to the technical field of touch, in particular to a method, a device, an accessory and a terminal for assisting touch equipment in presenting a writing track.
Background
With the development of computer technology, the input device of the computer has gradually replaced the keyboard and the mouse by the touch device. When the touch device detects the touch operation of a finger, the coordinate data is sent to the computer, and the touch driver installed in the computer in advance recognizes the coordinate data as the click or sliding of the finger, so that the computer operating system can execute corresponding operation according to the recognition result, such as page turning or dragging.
Due to the excellent performance of touch devices, they have been widely used in various fields, such as information inquiry, industrial control, military command, electronic games, multimedia teaching or office work, and the like. The practical requirement for writing on the touch device and presenting the writing track in real time occurs during the use of the touch device, and is particularly prominent in the field of multimedia teaching, such as writing on the touch device and presenting a blackboard writing in real time.
To meet the above requirements, two methods are generally adopted in the prior art: first, whiteboard software is installed on the computer, and the start button of the whiteboard software is presented on the touch device interface. When a user needs to write, firstly clicking a start button to enter a whiteboard page, then clicking a writing tool of the whiteboard page, and finally writing in a set area of the whiteboard page through fingers, wherein the thickness of a track line presented during writing is the same, and no pen point exists; when the user does not need to write, the user also needs to click the close button of the whiteboard page.
Obviously, in such a mode, the user is required to continuously click the button to realize the function switching between writing and non-writing, the operation is complex, and the writing track display effect is directly reduced due to the fact that the written track lines have the same thickness and no pen point, and poor user experience is caused.
And secondly, a matched standard pen is arranged for the computer to serve as input equipment of the computer, the standard pen is in communication connection with the computer, when the standard pen writes on the touch equipment, a writing instruction is sent to the computer, and the standard pen drive pre-installed in the computer identifies the writing instruction as writing operation of the pen equipment, so that an operating system of the computer can directly control the touch equipment to present a writing track according to an identification result.
Obviously, in such a way, the user can directly write and present the writing track without clicking a button, and the operation is simple, but the standard pen has a complex structure and high cost, so that the standard pen is unacceptable to general users.
