Embodiment 1

[0023] figure 1 A structural schematic diagram of the left-hand handle of the hand-held keyboard of the present invention is given, while the right-hand handle is symmetrical to it and is not shown. The handle shell 1 is a shell structure made of light organic material, its size and shape make it can be held in the hand more naturally, and the position of the key is like this: when normally held in the palm, the pad of the thumb Naturally fall on the main button 2, the root knuckles of the index finger, middle finger, ring finger, and little finger (the third section, that is, the root of the finger) naturally touch the main buttons 3, 4, 5, and 6, and the thumb can touch and press after a small movement from the natural position. Press the auxiliary button 11. The microprocessor circuit 8 is an ordinary single-chip circuit, which is connected to the motion detection unit 7 and calculates the moving distance. Microprocessor circuit 8 connects all buttons 2~6 and 11 simultane...

Embodiment 2

[0039] On the basis of Embodiment 1, by comprehensively utilizing the accelerometer, gyroscope and magnetic field sensor, more complex movements can be tracked to achieve more reasonable and effective hand position calculation, thereby achieving better results. Among them, the magnetic field sensor adopts Honeywell's HMC5883L weak magnetic field sensor chip, which can detect the strength and direction of the earth's magnetic field, and cooperate with the gyroscope to detect the attitude angle of the hand more completely. In addition to the practicality of the accelerometer, the translation can also be tracked and calculated.

Embodiment 3

[0041] As an improvement of Embodiment 1 or 2, a vibration feedback component (vibrator) can be installed in the hand-held keyboard, and the vibrator is activated at the critical point of the adjacent hand position to achieve tactile feedback, thereby Make touch typing possible. In the same principle, audio playback can also be introduced, and the sound characteristics correspond to the state of the hand position, which is also beneficial to the touch typing operation. The vibrator can be a rotor motor, a linear motor or piezoelectric ceramics.

Abstract

The invention discloses a hand-held keyboard. The hand-held keyboard comprises a pair of handles suitable for being held in a left palm and a right palm, wherein five or more than five buttons are distributed on each handle, and the five main buttons directly correspond to five fingers, that is, when the handle is held naturally, the five main buttons are in natural contact with any parts of the five fingers; movement detecting units for detecting the movement of hands, microprocessors, communication units, power supply units and the like are arranged in the handles; the buttons and the movement detecting units are connected to the microprocessors; the microprocessors are further connected to the communication units; the communication units are used for transmitting button pushing and position information to a computer and receiving relevant data from the computer. The invention further discloses a method for identifying button pushing and input of the hand-held keyboard. The hand-held keyboard lasts use customs of a current keyboard, supports high-speed touch-typing input, can be operated during moving, and is portable.

Description

technical field [0001] A computer information input device, in particular a portable hand-held keyboard, and an input method thereof. Background technique [0002] With the development of computers to this day, they are rapidly miniaturized, portable and mobile in various forms. Tablet computers, handheld computers, and smart phones are terminal devices that are small enough to be pocketed and have powerful computing and processing capabilities, but so far no suitable small and efficient information input devices have appeared. Although various information input devices emerge in an endless stream, such as touch screens, handwriting tablets, projection keyboards, air mice, and various miniature keyboards, we have found that none of them can achieve the efficiency and ease of use of traditional desktop keyboards and mice. For example, the input speed of touch screen and virtual keyboard is far lower than that of ordinary keyboard; although the projection keyboard is portable...
