Problems solved by technology

However, the above-mentioned physical keyboard will occupy a certain amount of space. The finger vein terminal needs to reserve a special place for the keyboard, which increases the size of the body. Especially when multiple characters need to be input, the number of character keys on the keyboard further increases the size of the body. Leading to an increase in product volume cost and difficulty in appearance structure design

Abstract

The invention discloses a character input method and device of a finger vein terminal. The method includes: recognizing a touch manner of a user finger through a finger sensing device of the finger vein terminal; and executing a corresponding character input operation according to a character input page of the touch manner in a display panel of the finger vein terminal. According to the technical scheme, the touch manner of the user finger can be recognized through the finger sensing device of the finger vein terminal, and the corresponding character input operation can be executed according to the character input page of the touch manner in the display panel of the finger vein terminal; character input is achieved through different touch manners of the user finger by means of a finger sensing function and a display function of the finger vein terminal; the character input device is easy to operation and use; entity keyboards can be avoided; the difficulties of finished products, a hardware design, and a structure design can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to character input technology, and in particular to a character input method and device for a finger vein terminal. Background technique [0002] The emergence of the finger vein terminal effectively solves the fraud phenomenon in fingerprint identification, and truly realizes accurate identification. [0003] Existing finger vein terminals generally include a finger vein core, a display module, a control module, and a keyboard, wherein the keyboard is used to input characters. However, the above-mentioned physical keyboard will occupy a certain amount of space. The finger vein terminal needs to reserve a special place for the keyboard, which increases the size of the body. Especially when multiple characters need to be input, the number of character keys on the keyboard further increases the size of the body. This leads to an increase in product volume cost and difficulty in appearance structure design. C...
