A handheld text scanner is a type of normal handheld scanner that is designed and used for scanning text of all types from any resource available. A normal handheld scanner is a compact type of scanner that is very small in size and can be utilized for multiple tasks related to scanning. The other major types are handheld barcode scanners that are used in super markets for scanning the code of the products, and handheld 3d scanners that are used for scanning 3D objects, 3D modeling, inspection, reverse engineering and more.
The handheld text scanner needs to be glided across the text to be scanned by hand. Such handheld text scanners have a “start button” on them which has to be pressed for starting a scan, and certain sensors for defining the line breaks. They contain rechargeable batteries that are charged while the handheld scanner is connected to a computer. Moreover, handheld text scanners have certain options for altering the optical resolution. Some handheld document scanners also have mini screens for viewing the scanned text and have options of translating and defining the text. They can also be used for learning the meanings of the text as most of these text scanners are programmed with a dictionary, which can translate and define the scanned words. Many students tend to use such scanners as a pocket dictionary.
Scanners basically read red-green-blue color data which is then processed for different exposure conditions and then sent to the computer through an input output device, usually a USB cable. Most of handheld scanners come with a USB cable.
Handheld text scanners are available in two types i.e. pen shaped scanner and a roller ruler shaped scanner. A pen text scanner scans a line word by word, whereas as roller ruler scanner scans a complete line in a blink. Both of these scanners’ memories can store up to 1000 of pages or more in it. Despite the compact size of handheld text scanners, they posses complete scanning technologies provided in any other larger sized text scanner. Handheld scanners are also less expensive compared to the full size scanners. Moreover, they need proper cleaning through infrared cleaners available in market. In short, a handheld text scanner is a brilliant combination of “intelligent design” and “creationism”.
Complementing their intellectual programming and variant functions, these days handheld document scanners are being used by office executives, teacher, doctors, students, lawyers etc.
