Technology makes many tasks easier in a variety of ways. Food is safer due to technology. Medical procedures and drugs are much easier to save more life communication than ever before - the CTIA Communications Group recently reported that the number of mobile phones in the United States exceeds that of people.
A pen scanner is another example of how technology can make tasks easier. These scanners are approximately marked thickness devices and are approximately 8 inches in length - depending on the intended use of the device. Some scanners can be placed horizontally to scan the entire page in one. Other scanners can keep scanning a word or phrase once like a real pen.
How to use these amazing devices? The pen scanner uses optical character recognition technology or OCR to upload images to the scanner and then convert the images into actual letters, numbers, words and phrases. "Optical" means that the scanner can only explain what it sees and how it "sees" it. This can be a problem for documents that are not completely flat, or if you want to interpret complex fonts or handwriting. OCR technology has come a long way, but it is not perfect, it may be wrong to read the text, or it is impossible to read the text at all.
For those who have dyslexia or want to learn to read, a pen scanner can make this work both interesting and educational. The device can be connected to a computer and the audio software can read the scanned content. In addition, for people with impaired vision, you can scan the document and zoom in on your computer screen.
Business people may find it convenient to quickly scan articles or paragraphs in newspapers or magazines and use them in presentations. Students can also use the scanner to capture key paragraphs in the text that may not be deleted from the library or student center.
When looking for portable scanners, consider using them first. Also look for devices that work well with your computer and software. Some scanners can scan images and text and store them as TIFF, GIF or JPEG files. Some scanners have their own speakers that make a sound when scanning. Also consider scan capacity - some devices can hold up to 100 or more articles. Battery capacity is also important - you don't want to scan the beach and the pen scanner fails due to low battery.
Technology makes the task easier. A pen scanner is just one example of how technology can help in many ways.
