Optical Mark Reader (OMR)

(OMR):


Optical, mark recognition is the process of capturing data by contrasting reflectivity (low reflection: high reflection) at predetermined positions on a page. By shining a beam of light onto the document, the scanner is able to detect a marked area because it reflects less light than an unmarked surface.

          It is generally distinguished from optical character recognition by the fact that a recognition mechanism is not required, That is, the marks are constructed in such a way that there is little chance of not reading the marks correctly.

          One of the most familiar applications. of optical mark recognition is the use of HB pencil bubble optical answer sheets in multiple choice question examinations. Students mark their answers, or other. information, by darkening circles or ovals or sqrares on a pre-printed sheet. Afterwards the sheet is automatically graded by a scanning machine.

Automations and robotics

Automations and robotics refer to the use of technology to automate and perform tasks that were previously done by humans. Automation involves the use of software, machines, and other systems to perform tasks without human intervention. Robotics, on the other hand, involves the design and development of machines that can perform tasks autonomously or with limited human intervention. Automations and robotics are widely used in industries such as manufacturing, healthcare, transportation, and agriculture. In manufacturing, robots are used to perform repetitive and dangerous tasks, such as welding and painting. In healthcare, robots are used to perform surgeries and assist patients with mobility issues. In transportation, automated systems are used to control traffic flow and ensure the safety of drivers and passengers. In agriculture, robots are used to plant and harvest crops, reducing the need for manual labor. Advancements in technology have led to the development of more sophisticate...
