[Previous technology] ° Press 'For the type of femoral obstacles that ca n’t be typed with the standard keyboard:' Yes, it ’s effective. Instead of 5 vowels (long and short standing population Feng Houze code with only two basic obstacles), it can combine a variety of different characters, which is equivalent to mental and physical disability, and it can be input by a single key. ? Characters: In addition to the single-button Morse code input, you need to memorize each (^^ but also after a considerable amount of input speed control training by the association * · short-to-tone ratio 3: 1) 'to be accurate Character input, but ψ 'is not easy to maintain a stable standard ratio. Generally, the timing of the Morse code for j for physically handicapped people is quite unstable and difficult to identify. The reproducibility and convenience are greatly reduced. 〃 Furthermore, people with physical and mental disabilities cannot be effective due to physical obstacles. 丨 ·· jjbb Fen Beikou ^. Two early control actions, so when using Morse code for input, hang 4 -χ- < Unstable input operation may occur. These unstable input actions will cause unstable Morse code sequences to 'make Morse codes stable in the automatic recognition system and generate recognition errors'. Therefore, whether the recognition method is stable will directly affect the recognition results of non-Morse code sequences; Therefore, the lack of input speed control is improved-allowing the input system to correctly adjust the user's input speed to adjust the level. The $ 2 level is the most direct and effective method, but before 1995 , Is designed for normal learners, for input speed I machine ... a ------------------ 1238963

The degree of stability is extremely strict, and it is difficult for people with disabilities to maintain a constant input speed. Therefore, how to design a system that can identify irregular input speed is important. [Summary of the Invention] The present invention is to carry out innovation and improvement in two directions such as practicability and improving the recognition rate. The core is a simple and fast Fuzzy recognition system with a single-chip microprocessor to design a code suitable for people with disabilities. The signal input system, because of the disability of the physically and mentally handicapped people, the parts that can be used to control the movement are also mostly different, such as the head, mouth or other parts. Fang ^, even single-signal input devices that can be controlled or head-swayed. Those who can't control the input of Morse code long and short tones with a single key can also use dual signals ... (long and short two tones) with Fuzzy The code recognition algorithm is used as the input °. The system architecture mainly includes a single-signal or dual-signal input device, a fuzzy Morse code recognition algorithm, and a 1/0 interface. The system uses the Fuzzy Morse code recognition algorithm to make The unstable Morse code sequence is correctly identified, so that the single or dual signal input system can be used by any person with a disability to achieve correct use. The purpose of the brain and control of other equipment, and the operator's selectable functions are scored into four parts: keyboard mode, mouse mode, training mode, and remote control mode; the Morse code entered is modified by M0fSe2 000 tabiei, Table 2 and table 3 are mainly defined (see attachment).

[Embodiment] In order to know the computer or other related equipment, the present embodiment will be described below in order to make your reviewing committee have a better understanding of the present invention. Further understanding, the "code signal input system dual signal input device, Fuzzy Morse code miscellaneous" of the present invention means that the system mainly includes a single or a minute, the user uses the single or double dagger to dry the code, and the algorithm And the "FUZZy" recognition of the three automatic adjustment functions of the interface, input the Morse code, and adjust the Mosma voiced and non-harmonic dots in accordance with the interval between the short and long sounds of the sound sequence, while the long and short sounds of the silent sequence refer to the word The long and short sound of the standing sound sequence refers to the dash. Among them, the single signal input device inputs the long interval (the interval and the character interval), and the fuzzy Morse code recognition algorithm adds 9 3 / said Morse code. It is transmitted to and converted into a readable and dual-signal input device through the I / O interface, and is used for inputting signals to other broadcast or other related equipment.

(Take single number as input device as an example) Input L as early as possible (1) Single signal input device

The single-signal input device is a device that uses a single key to make the Morse code long and short. 'For severe patients |' If there is only a head-movable spinal cord injury, a mouth-controlled single-key switch is used as a single-signal input device to control ^ or equipment. Considering the severity of the injury, the mouth control switch (single signal input device) is currently designed with two types: bite type (see the second figure) and blow type (see the third and the figure). This single signal input device can be customized according to the user. I want a special design for the degree of injury I. The occluder switch uses the teeth to gently bite a single key to open A to quickly enter the Morse code, while the air-blown opening in the third picture is advantageous, and air is blown at the air outlet B The input of Morse code by cheek agitation also has the same function as the one-button switch A. Of course, the single-signal input device can also be designed as other types of input devices, that is, the design of special input devices according to the needs of users. In addition, in the second picture, the nipple-type mouth control switch in the lower right corner of the bite-type mouth-control switch diagram can also use the double-flat nipple c as the external interface, and directly insert a moderate-size mouth control switch. Mouth control The switch is _ iron piece D 'without the need for an additional lock device. In addition to the convenience of replacement, it can be revised every five months, and the description of the invention (5) can be easily removed for cleaning and disinfection after use. User $ — A clean and comfortable interface. In the operation, the auxiliary flat iron D is linked by biting the bi-flat pacifier c ', and at this time, the auxiliary flat iron D is the role of the key switch A. τ (1) Morse code identification algorithm The Morse code identification algorithm of this system is described in detail below: (1) Morse code identification algorithm This identification method is constructed by fuzzy logic (Fuzzy Algorithm) -based Mu broadcast μ ^ long and short tone judgment threshold, in order to improve the ancient „„, the application of Fuzzy algorithm to modify the rate at any time (the fourth figure shows the output of the No. 4 input controller is the correct dual signal input, Ready to use dual switches, 5 system block diagram). In addition, if the fuzzy algorithm is used to modify the word invitation at any time to express the long sound, and the other represents the value of the short sound, in order to improve the double signal input device, the discriminating valve Ganshi interval time is positive pain. rate. Eighth, the system variable of this system I Morse code short tone input, if round, as follows: The proportional relationship normalizes the long tone to short standing ~, long tone, then according to the Morse code 3 ··! For dual signal input, !! Morse code wheel / enter X (input variable), as well as the interval time of the Morse code. If there is no silent button time (that is, the interval between characters), it will not be processed (round in ^ ^ is a silent long note) (I.e. word-to-word

Yk · Morse code short tone prediction value) When inputting y number, y is selected as Morse code without dramatic variables), but if it is double signal). The prediction value of the ugly sound (the output variable e: the error between the input and the predicted value ek: the correction value of the predicted value ($ (Uzzy input variable) tUzzy output variable). 1238963 Case No. 92126574 Revised in January, V. Description of the invention (6) T k: the threshold value of the Morse code length and short tone, multiply y by 2 (which is the middle value of 3: 1), that is, the threshold value of the Morse code length and short tone, as the long and short tone of the next input Discrimination level; if it is a dual-signal input, T is the discrimination threshold of the word-to-word interval time, that is, multiplying y by 2 (take the middle value of 3: 1) as the discrimination level for the next input Fuzzy calculation steps are explained as follows: 1. When an input (Ik) enters the system, the threshold value (T 0) is initially determined by the short and long tones, and then the input value is adjusted by the function f 涞.

xk = Ik, if I k < Tk f τ {xk = (l / 3) Ik, if Ik 2 Tk (1) However, if it is a dual signal input, step 1 is: when an input (I k) enters the system At first, the threshold value of the word-to-word interval time (T 〇 is determined first, and then the input value is set by the function f 涞, fT · xk = Ik, if Ik < Tk (1)

2. Find the prediction error e k as the input value of the Fu z z y algorithm. ek = x 「yn (2) Use the semantic fuzzy rule to calculate the short-sound error correction value e’ k, the semantic variable LN is negative, SN is negative, ZE is zero, SP is positive, and LP is positive:

Modify short-distance prediction value And long and short tones lost: iM stands. However, if it is a dual signal, ‘J :: = positive’ is short: the predicted value and the word-to-word: when the second one is used as the recognition level for the next input. ~ &Amp; = yk-! + E \ ⑻

Tk = 2yk_i (4) △ or more 'Repeat steps 1 to 3, so that the system can adjust the system parameters according to the user's use state to achieve a stable input effect. (2) Stability test of the fuzzy algorithm—This = the one shown in the five figures is to use the sin ne sinusoidal function to simulate the speed change. # ^ Some random noise to build a short sequence of Morse code (black dots) to measure Prepare the stability of Uzzy identification system. … From the fifth figure, it can be seen that the fuzzy recognition system can adjust the prediction value (dashed line) as the input time grows. Some points in the figure and the changes between the points (such as area (I) and area (II)) The data distribution of area (1)

The magnitude of the slow change is great, but the fuzzy identification system will only follow the original implementation and make small adjustments slowly, so that the system will not cause the system's instability due to sudden changes in the characteristics of the system. The data of the area (I 丨) shows a decreasing trend and then gradually increases. The Fuzzy recognition system follows the change ^ and slowly makes corrections. Therefore, when the signal is stable, the FUZZy recognition system can be quickly corrected. Therefore, the Fuzzy recognition system is a fairly robust system; the choice of single and dual signals is mainly designed to meet the needs of people with different degrees of physical and mental disabilities. (C) The four major functional modes of this system (keyboard, mouse, practice and remote control mode) '※ Keyboard mode: 1. Common characters English characters (a ~ z), symbols (' {',' / ', ···} and function keys (Tab, Caps Lock, Ctrl, Alt, Shift, Enter, ". etc. The general character Morse code is defined in Morse200 0 tablel (as attached). Chinese phonetic symbol: Taiwan keyboard The configuration positions corresponding to English characters are mainly on it. The corresponding Morse code is separately defined in Morse20 00 tablel. 02. Direction key action function correction. Because Morse2000 tablel has the definition of arrow keys —, t, i, —, they are “Six Morse Codes” is therefore extremely inconvenient to be applied to the computer document editing of early key input. In order to allow users to edit the document editing process in an easier and simpler way, the keystroke action of the arrow keys is modified here to reduce Press the number of keys to achieve better results than before. Reduce the number of keys to achieve better results than before.
