Embodiment approach

[0096] An implementation manner of determining the current mode of the system is provided below, specifically as follows:

[0097] If the processing control module detects bright spots in the writing activation area 310 and no bright spots in the erasing activation area 311, it is determined that the current system is in the writing mode;

[0098] If the processing control module detects bright spots in the erasing activation area 311 and no bright spots in the writing activation area 310, it is determined that the current system is in the erasing mode;

[0099] If the processing control module detects that there are no bright spots in the writing activation area 310 and the erasing activation area 311, it is determined that the current system is in the cursor movement mode, if there are bright spots in the writing activation area 310 and the erasing activation area 311 , and it is also determined that the current system is in the cursor movement mode.

Abstract

The invention discloses a transparent desktop handwriting input system and method. The method comprises the following steps: turning on an enhanced light source to illuminate the interior of a transparent desktop; defining a judgment criterion of the effective bright spots; dividing the writing area, the writing activation area and the erasing activation area on the transparent desktop; the image acquisition module continuously acquires images of an area where the transparent desktop is located below the transparent desktop; determining that the current system is in a writing mode or an erasing mode or a cursor moving mode; and the processing control module tracks the moving track data of the effective bright spots in real time, marks the track data as handwriting data or handwriting erasing data or cursor moving track data according to the current mode of the system, and transmits the data to the intelligent terminal. The invention relates to a handwriting input device and a handwriting input method. A transparent desktop is not provided with a handwriting sensing panel or any electronic component, but supports handwriting input and handwriting erasing.

Description

technical field [0001] The invention relates to a handwriting input device and method, in particular to a transparent desktop handwriting input system and method. Background technique [0002] Since office work and study are usually carried out on the desktop, directly using the desktop as a handwriting input device will bring extremely high convenience, so it has always been a relatively popular research direction. The difficulty of directly using the desktop as a handwriting input device is that ordinary desktops lack the medium needed to recognize handwriting input. To make the desktop capable of handwriting input, the usual solutions are mainly divided into the following two types. [0003] One solution is to make the desktop itself have a handwriting sensing medium, such as adding a handwriting sensing panel or a touch display panel to the desktop, so that the desktop becomes a large-sized handwriting pad or touch screen, capable of supporting handwriting input .
