Embodiment Construction

[0053] In the present invention, the upper sensitive unit 4 and the lower sensitive unit 7 directly adopt a copper-based material with a thickness of 0.3 mm to be processed into a circular diaphragm with a diameter of 60 mm, and at the same time, a hole with a diameter of 10 mm is processed in the center for connection with the central shaft 3. Align, and process 4 holes with a diameter of 3.2mm at a position with a diameter of 20mm. The directions of the holes are perpendicular to each other. 5mm hole,

[0054] The leads for the upper sensitive bridge are connected to the pre-signal processing circuit board 8 . The outer diameter of the central shaft 3 is 28mm, and the two ends are processed with steps with a diameter of 10mm and a height of 2mm. The specific assembly is to match the steps at both ends of the central shaft 3 with the center holes of the upper and lower sensitive units, and make the ends by pasting. The upper part and the upper and lower sensitive unit planes...

Abstract

The input platform composed of hand plate, signature plate, sense structure of 5D force/moment (including central axis, sensing unit, and coupling flange), front end signal processing circuit, general bus, network interface and base is utilized to detect and record information of force/moment between writing pen and the signature plate. Using information of force/moment detected from the input platform obtains information of figure, orders, strokes and writing speed in procedure of hand writing input. The input platform can be used as input peripheral equipment of computer, and any kind of pen can be used to write on the input platform without need of expending ink. The platform can be embedded into computer system to replace keyboard to realize handwriting input. Moreover, the invention can apply to encrypting signature and signature for anti false needed in some situations in E-commerce and E-government affairs.

Description

technical field [0001] The present invention relates to the fields of computer information and automated electronics, in particular to a novel computer handwriting input platform and handwriting information acquisition method, which are used in applications such as e-commerce and e-government that require encrypted signatures and anti-counterfeiting signatures, and can be directly used as personal computers input peripherals. Background technique [0002] In e-commerce, e-government, office automation and digital electronic handwriting input urgently need a convenient, fast, natural and safe way. At present, there are many mature methods and technologies for digital signature and handwritten input in this field, but digital signature and handwritten input are separated from each other and are not implemented in the same system. In addition to requiring a natural, convenient, and fast input method, digital signatures require the uniqueness, security, and confidentiality of b...
