Embodiment Construction

[0016] The input of letters and the input of numbers are often separated, that is, in most cases, in a relatively long period of time, people only input letters or only numbers. For example, when people input a phone number, they only need to input numbers, and when people send text messages, they often only need to input letters and punctuation marks. Therefore, if letters and numbers are concentrated on one key, there will be no need to switch input frequently. Mode and cause input inconvenience. Therefore, in the embodiment disclosed in this specification, numbers and letters are concentrated in the same key. The keyboard has two input modes: letter input mode and number input mode. In each input mode, each main key or accessory The characters represented by the keys are unique, so the number of keys can be reduced without reducing the convenience of using the keyboard. The switching between the letter input mode and the number input mode can be accomplished by pressing a funct...

Abstract

The invention relates to a combined key-type keyboard, electronic device and the character input method thereof. And the input method comprises the steps of: providing a combined key-type keyboard, which comprises several combined keys, each comprising a main key and at least an auxiliary key, where each main key and each auxiliary key separately stand for a character, and the main and auxiliary keys are adjacent and able to be pressed, separately or together; pressing a combined key; judging whether the auxiliary key of the combined key is pressed; if the auxiliary key is pressed, selecting the character the auxiliary key stands for; otherwise, selecting the character the main key stands for. And it meets the requirement for character input on a portable electronic device.

Description

【Technical Field】 [0001] The invention relates to a composite key keyboard and a character input method, in particular to a composite key keyboard and a character input method used on an electronic device. 【Background technique】 [0002] Nowadays, there are more and more portable electronic devices such as mobile phones, PDAs, and electronic browsing devices. These electronic devices generally have one or more of the functions of SMS, e-mail, and notepad. Entering text on the above has become a must. Therefore, it is necessary to provide a keyboard on a portable electronic device. Limited by the size of the electronic device, the size of the keyboard cannot be very large. The size of the keys can be reduced and several characters can be integrated on a key. This is also inconvenient for finger operation, and often requires several operations to input a character. It is also possible to reduce the size of the keys without integrating several characters on one key. However, since t...
