Description

A kind of wearable glove keyboard

Technical field

The utility model relates to a kind of keyboards, more particularly, to a kind of wearable glove keyboard.

Background technique

(soft keyboards such as on-screen keyboard, laser keyboard are removed) in existing physical keyboard, can be mainly divided into mechanical keys Disk, membrane keyboard and direct capacitance keyboard three categories.The working principle of membrane keyboard is that the electricity arranged in length and breadth has been laid in keyboard Route, the position of intersection are exactly key mapping, and when key mapping is pressed with regard to trigger switch, the control chip of keyboard is by detecting all rows Alignment judges corresponding line and opens corresponding point, and this signal is passed to host.The structure of mechanical keyboard more passes System, using metalloid touch switch, working principle is that contact is made to be turned on or off, and has that simple process, noise be big, Yi Wei The characteristics of shield.Mechanical keyboard is earliest adopted structure, and contact is connected in the principle of general metalloid touch switch Or it disconnects.And direct capacitance keyboard is similar with membrane keyboard, generates electric signal simply by capacitor both ends distance change.

In addition, there is also a small number of software keyboards on the market, that is, uses silica gel to replace plastics as keyboard case, make keyboard It can roll, be convenient for carrying.

For conventional keyboard (membrane keyboard, mechanical keyboard, direct capacitance keyboard), although its advantage is different, All have the shortcomings that volume is big, not readily portable.Although noise is bigger when using, especially in addition, mechanical keyboard feel is preferable It is to be easy to bring inconvenience to other people in quiet environment (bedroom, office, library etc.), causes being discontented with for people around.It is quiet Although capacitor keyboard sound is smaller, there is quietness, due to its process characteristic, the price of direct capacitance keyboard is often higher, For average price more than 1500 RMB, sexual valence is relatively low.

And for existing software keyboard, it is printed on due to its circuit between softer silica gel and thin plastic sheet, keyboard Toughness is had a greatly reduced quality, and is easy to become insensitive since circuit is impaired, service life is also more of short duration.

Utility model content

The purpose of this utility model is exactly to provide a kind of wearable to overcome the problems of the above-mentioned prior art Glove keyboard solves the problems, such as that conventional keyboard volume is excessive, not readily portable, allow people different environment (hire out dickey seats, More crowded place, the place to need peace and quiet, the at one's side only keyboards such as mobile phone equipment inconvenient to use) under efficiently done It is public.

The purpose of this utility model can be achieved through the following technical solutions:

A kind of wearable glove keyboard, the glove keyboard shape are gloves, and glove bodies are soft material, and finger tip is equipped with Pressure sensor, finger part be equipped with bending sensor, glove bodies be equipped with CPU and communication module, the CPU respectively with Pressure sensor, bending sensor are connected with communication module, and CPU carries out key mapping analysis according to the sensor signal received, and The key mapping information that analysis obtains is sent to external equipment by communication module.

The communication module is bluetooth module.

The glove bodies are nylon material.

The glove bodies have a materials at two layers, the pressure sensor and bending sensor be fixed on materials at two layers it Between.

The back of the hand position of gloves is arranged in the CPU and communication module.

The bending sensor includes the insulating protective layer of outer layer and the conductive strips of internal layer and conducting wire, and described leads Electric band and conducting wire are arranged in parallel, are located among insulating protective layer.

The CPU is connect with pressure sensor and bending sensor by conducting wire.

Compared with prior art, the utility model has the advantage that

(1) quietness: gloves are using soft materials such as nylon, and different with mechanical keyboard and membrane keyboard, this is practical new Type detects the pressing of user's finger by the pressure sensor on finger tip, therefore does not need any hard mechanical structure and can be achieved with This function.Therefore, the utility model can work under extremely low volume.

(2) Indistinct Input characteristic: the glove keyboard of the utility model fault-tolerant ability with higher in typewriting.It is so-called " fault-tolerant " refers to that the key position pressed even if user is offset slightly from correct position, and keyboard still being capable of Correct Analysis and key Enter correct character, this is nearly impossible on mechanical keyboard and film keyboard, because the two requires user's pressing one A specific position.However, the data that the utility model is analyzed are only user gesture, therefore no matter somewhere user Correct letter can be keyed in by pressing.Since it does not need any physics key mapping, the utility model has very strong fault-tolerant energy Power.

(3) portability: the size of the utility model and common silk quality gloves is identical.In general, it Full-size be slightly larger than user hand.But the material of the utility model is quite soft, and can carry out appropriate fold It puts, so the space shared by it is more much smaller than conventional keyboard, again smaller than most software keyboards.This is also applied for carrying musette bag Women, because conventional keyboard is difficult to carry for them.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the present embodiment glove keyboard；

Appended drawing reference:

1 is pressure sensor；2 be bending sensor；3 be CPU.

Specific embodiment

The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model Shield range is not limited to the following embodiments.

Embodiment

As shown in Figure 1, a kind of wearable glove keyboard, which is gloves, and glove bodies are soft two layers Material, such as nylon material.Finger tip is equipped with pressure sensor 1, and finger part is equipped with bending sensor 2, pressure sensor 1 and curved Bent sensor 2 is fixed between materials at two layers.Glove bodies are equipped with CPU3 and bluetooth communication, and CPU3 is passed with pressure respectively Sensor 1, bending sensor 2 are connected with bluetooth communication, and CPU3 carries out key mapping analysis according to the sensor signal received, And the key mapping information that analysis obtains is sent to external equipment by bluetooth communication.

The back of the hand position of gloves is arranged in CPU3 and communication module.

Bending sensor 2 includes the insulating protective layer of outer layer and the conductive strips and conducting wire of internal layer.Conductive strips and conductor flat Row arrangement, is located among insulating protective layer.

CPU3 is connect with pressure sensor 1 and bending sensor 2 by conducting wire.

The present embodiment glove keyboard product workflow:

1) when working, user wears gloves, and bending sensor 2 records the bending situation of user's finger, and uses pressure Force snesor 1 records the dynamics that user presses each finger.Digital flexion is bigger, and resistance is bigger.The resistance meeting of bending sensor 2 Become lower.On the other hand, when finger firmly presses on the surface, the resistance of pressure sensor 1 can also change.

2) bending to sensor acquisition and after pressure data handles (is used in demo by miniature CPU3 Arduino is tested) data are handled.By the program onboard installed, our product can be carried out data Processing.It is extracted from inductor, and corresponding with the key on computor-keyboard.This database also is stored in the utility model In chip.

3) the key mapping information for having handled completion in this step, is transferred to computer bluetooth module, it will be originally practical new Type is connected on the computer of user.After establishing the link, crucial key mapping information is passed to computer by the utility model.
