Single-hand moved chord keypad, mark, structure and application thereof

Abstract

The invention relates to an omnipotent single-hand moved chord keypad, a mark and a structure thereof. The omnipotent single-hand moved chord keypad is provided with auxiliary functional keys, such as Shift, Fn, Sym, and the like, under a 12-key type 3X4 numeric phone keypad. All the characters and functions of a QWERT 102 keypad are completely replaced by a chord (combination) key of the omnipotent single-hand moved chord keypad. The omnipotent single-hand moved chord keypad can be hinged with a phone and a handheld computer, for quickly inputting Chinese characters and English letters anytime and anywhere, and can be made into input devices, such as a mouse keypad, a touch plate keypad controlling computer or remote controller, a password input unit, and the like. The omnipotent single-hand moved chord keypad can be used for the vehicle-mounted and moveable equipment or the keypads of electronic devices of various instruments and large-size equipment in various industries. The omnipotent single-hand moved chord keypad has the characteristics of small volume, complete function, high inputting speed, complete mark, comfortableness in operation, benefit to health, multifunctional key, convenience in opening and closing, suitability for touch typing, accordance with a present habit of a user for operating a computer keypad, suitability for the inputting of various characters in the world, suitability for the quick inputting of the user while walking, and suitability for a future trend of the miniaturized and movable equipment.

Description

technical field [0001] The invention relates to an all-round mobile one-handed chord keypad, a mark and its structure, which can be widely used in mobile phones, smart phones, mobile computers, MIDs, smart books, mobile Internet terminals, cloud computing terminals, SaaS terminals, Internet of Things terminals, Handheld electronic devices such as electronic dictionaries and handheld game consoles can also be used in mobile devices such as vehicle-mounted, airborne, and ship-mounted devices, and can also be used as keyboards for embedded devices such as various instruments and industrial equipment in various industries, or as external keyboards , mouse with keyboard, remote control, password input device, access control and other input devices. Background technique [0002] As an essential human-computer interaction input device for electronic products such as computers, laptops, and mobile phones, keyboards are always in close contact with people in their work and life.

Problems solved by technology

[0003] With the advent of the mobile Internet and 3G era, as well as the development of cloud computing and unified communications, the role of mobile phones is undergoing a fundamental change. Voice services have dropped sharply, non-voice data services have grown rapidly, and mobile phones have been given more and more Powerful functions, word processing and interactive control have become important functions of mobile terminals. Mobile phones are changing from a traditional mobile phone to a personal mobile Internet terminal. Inconvenient, the same button has multiple characters, and it must be pressed multiple times to input a character, usually only 8-20WPM (words per minute) input speed, cumbersome operation, low efficiency; although the input speed of the full keyboard mobile phone is slightly It is better than a 12-key mobile phone, but its small and narrow keys are crowded together, it is easy to touch the keys by mistake, cannot touch the keys, and still cannot reach the ideal input speed, and cannot achieve the ease and speed of typing on a computer keyboard; The virtual keyboard input speed of iPhone and other mobile phones is slower than that of full-keyboard mobile phones, and the input error rate is much higher; at the same time, only using the thumb to operate the keyboard is one of the important reasons for the slow input speed of existing mobile phones

In short, the existing mobile phone keyboards are far behind the development speed of handheld devices, and have become the input bottleneck of mobile terminals, which are far from meeting people's needs for mobile life.

[0004] Although the existing computer PC keyboard has many functions and fast input, and has ten times the input speed of the mobile phone keyboard, its number of keys is too many and the volume is huge. Even the notebook computer NB keyboard is too large and must be placed in a fixed place where it can In use, it can only operate under relatively static conditions, and is limited by the occasion of use, so it cannot play the role of seamless and smooth access and use anytime and anywhere; at the same time, the existing QWERT keyboard does not conform to ergonomics, and has many disadvantages. Seriously damage the health of users. When people use the keyboard of a computer or laptop, they must sit in front of the computer, with their shoulders and arms folded, their hands outstretched and suspended in the air. In order to ensure fast and accurate input, people are confined to the seat in front of the computer, and it is easy to cause their hands to fall. Muscle tension will generally damage the palms, wrist joints, cervical spine, and shoulders, causing physical fatigue and injury. Long-term use of this keyboard is prone to keyboard hand, wrist syndrome, cervical spondylosis, myopia, spinal nerve injury, bone Hyperplasia and cumulative musculoskeletal injuries in the neck and waist, once the pain occurs, it is difficult to recover

In addition, the globally popular QWERT keyboard key distribution is extremely unreasonable. The most commonly used 8 ETOAIRS letters are far away from the specified finger starting position (J, F guide keys), which is not conducive to improving typing speed. The weak left hand and the weakest The left and right little fingers of the computer are responsible for more important or more keys, and the layout of th...
