Abstract

The invention discloses a virtual keyboard calculator pen which is composed of an outer shell (1), a screen projection hole (2), a keyboard projection hole (3), a signal transducer (7), a calculator main chip (4), a storage battery (5), a cartridge (6), a pen clip (8) and a pen cap base (9). The keyboard projection hole (3) enables a client operation interface of a calculator to be projected to a table top or a wall surface, when a virtual button on the operation interface is pressed, certain light rays which are emitted out from the screen projection hole (2) are shielded, and shielded signals are transmitted to the calculator main chip (4) through the signal transducer (7). The calculator main chip (4) obtains signs which are input by a client from the operation interface by information processing, a result is obtained by calculating, and the result is projected to the table top or a wall through the screen projection hole (2). The virtual keyboard calculator pen has the writing function of a pen and has the functions of a virtual keyboard calculator and projection at the same time.

Description

technical field [0001] The invention relates to a virtual keyboard calculator, which belongs to the technical field of computer applications. Background technique [0002] Calculator, because of its wide application in various industries, is one of the essential gadgets in people's life [0003] However, general calculators are generally larger in size due to their physical keyboards and display screens, and are not very convenient to use on some occasions. If the keyboard and display screen of the calculator can be virtualized by using optical and computer signal processing It will greatly reduce the volume of the calculator to facilitate portability. The invention virtualizes the keyboard and screen of the calculator, and integrates its functions into an ordinary writing pen, so as to realize the dual-purpose functions of the calculator and the pen of the virtual keyboard and screen. Contents of the invention [0004] The object of the present invention is to provide a...
