What is a manual scanner of the text?
Handheld text Scanner is a device that can "read" printed or manually written text, find out what he says, and then turn it into a text file for a computer. This can help digitize old documents that exist only in printed form. It can also be used in conjunction with the text converter to speech so that people with visual disabilities can “read” printed material.
One of the most important aspects of the manual text scanner is the quality of its optical character recognition or OCR. This is a system that converts a picture captured by the scanner to the text. As a simplified explanation, the system usually acts by finding which space contains one character and then analyzes the area covering this space. The system then breaks this area into the grid of many smaller sections and marks each of them simply dark or light. It then compares the formula in the entire area with a database and decides which character is the formula closely closely corresponding to.
The power of the handic text scanner may vary extremelyLOCES for quality and sophistication of the OCR system. Very basic systems will only work with a few known scripts. The most advanced systems can even work with the manuscript. In some cases, it may be possible for the system to either recognize the shape of the word, or look at its interpretation of individual characters and find any mistakes he made at the context of the overall text.
The system used by any manual text scanner will usually be less accurate than text input devices, such as a digital pen system. This is because the PEN system can record the direction of the individual strokes provided by the user and provide more information for the evaluation of individual letters. The manual text scanner only works with the text that is already in place, so it has less information.
The most common form of Handheld Text Scanner is a similar pen. This will have a lens in a position that the tip would be in a normal Peru. Some versions must be connected to the computer. Others have built -in tEchnology of processing and can store a certain amount of text on board, which can then be transferred either by a cable connection or a removable memory card. One variation on the manual text scanner is a translation device that can scan a piece of text in a foreign language, recognize it, and then create a translated version.
