Embodiment approach

[0035] The controller described in the embodiment of the present invention may be a control chip provided on a detection board, or may be a controller on an electronic device such as a tablet. As a preferred embodiment of the present invention, the detection board can be connected to a controller in an electronic device through a common connection interface.

[0036] The prompting device may include a speaker, a prompt lamp, and a screen for displaying prompt messages. Of course, multiple prompts can be used at the same time, and different prompts can be set to correspond to different judgment results.

[0037] As a further optimized implementation of the embodiment of the present invention, such as figure 1 As shown, the intermediate layer 14 is an insulating grid layer, and the grid size of the insulating grid layer is adapted to the size of the tip of the writing pen of the writing tablet. For example, when the tip of a writing pen is thicker, the mesh of the insulating grid la...

Abstract

The invention provides an identification device for the condition that strokes go beyond a writing area of a writing pad. The device comprises a detection plate arranged on the surface of a writing pad; the detection plate is provided with a hollow-out area corresponding to a writing area of the writing pad; the detection plate comprises a first electrode layer, a second electrode layer and a middle layer arranged between the first electrode layer and the second electrode layer and used for making the first electrode layer and the second electrode layer connected when receiving extrusion; the first electrode layer and the second electrode layer are connected with a controller which is connected with a prompt device. The device can timely prompt users that writing goes beyond a writing area and can effectively reduce writing error of users.

Description

Technical field [0001] The invention belongs to the field of writing boards, and in particular relates to a recognition device and method for strokes beyond the writing area of ​​the writing board. Background technique [0002] The writing pad is a convenient input tool. For electronic devices equipped with the writing pad, the writing pen equipped with the writing pad can facilitate the user to draw or input text. [0003] The current writing board includes a writing area set on the front of the writing board. When a user writes on the writing area with a writing pen, the strokes written on the writing board will be recorded and recognized by the electronic device, thereby effectively storing The user enters the content of the writing board into the electronic device. [0004] When using the writing pad to write, if the user does not pay attention when writing, the writing pen may exceed the writing area of ​​the writing pad when writing, which will cause the loss of some data that...
