Embodiment Construction

[0034] figure 1 It is a schematic diagram of the overall structure of the handwriting input platform of the present invention, which is composed of an armrest plate 1, a signature plate 2, a central axis 3, an upper sensitive unit 4, an upper connecting flange 5, a lower connecting flange 6, a lower sensitive unit 7, a front The signal processing circuit 8, the universal bus network interface 9 and the base 10 are jointly composed.

[0035] Among them, the armrest plate 1 and the base 10 can be an integrated structure, depending on the installation position and size of the signal processing circuit, the signature plate 2, the upper sensitive unit 4, the lower sensitive unit 7, the upper connecting flange 5, and the lower connecting flange 6. It is necessary to ensure the coincidence of the central axis, which is realized by the shaft-hole cooperation, that is, there is a concave cylindrical cavity in the center of the signature plate 2, the inner diameter is equal to the outer...

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 invention relates to the fields of computer information and automated electronics, in particular to a novel computer handwriting input platform, which is used in applications such as electronic commerce and e-government that require encrypted signatures and anti-counterfeiting signatures, and can be directly used as input peripherals for personal computers. 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 biometric features. [0003] Digital electro...
