A pointing device just changes your location on the screen (moves the cursor). A scanning device converts printed output into digital input for processing by the computer.
When selecting scanning survey software, key features to consider include compatibility with scanning devices, ease of use, data analysis capabilities, customization options, and security measures to protect survey responses.
Offset scanning is a technique used in various scanning technologies where the scanning head moves slightly from side to side while capturing an image. This movement helps to reduce the effects of artifacts and improve the overall quality of the scan by ensuring that each point on the scanned object is captured from multiple angles. Offset scanning is commonly used in document scanners and medical imaging devices.

In the past, dedicated scanning devices were mainly used for the automated grading of multiple choice tests. As technology has advanced, most devices with a scanning bed can be used to transfer the image to a computer that has automated grading software installed. There are even grading apps for mobile devices that captures and reads the image of a completed multiple choice test.
Earlier TV devices had been based on an 1884 invention called the scanning disk, patented by Paul Nipkow.
