Asked in Computer Hardware Disadvantages of optical mark reader?Short for o ptical m ark r ecognitionthe technology of electronically extracting intended data from marked fields, such as checkboxes and fill-infields, on printed forms.
OMR technology scans a printed form and reads predefined positions and records where marks are made on the form.
This technology is useful for applications in which large numbers of hand-filled forms need to be processed quickly and with great accuracy, such as surveys, reply cards, questionnaires and ballots.
A common OMR application is the use of "bubble sheets" for multiple-choice tests used by schools. The student indicates the answer on the test by filling in the corresponding bubble, and the form is fed through an optical mark reader also abbreviated as OMRa device that scans the document and reads the data from the marked fields.

Old Mahabalipuram Road. Asked in Computer Terminology Explain how omr is used to help mark tests? In theory it could, but it would make it considerably slower and inefficient and almost impossible to run, so using OMR is very important.
OMR stands for Optical Mark Reader or Recognition OMR is used to read forms which have variable size field entries and the entry can be in form of a check mark, a cross, or some scribble.
These forms include but are not restricted to automated entry sheets where the user needs to fill in an oval shape with a number 2 pencil. OMR usually needs a blank form and a definition of entry zones. Apart from all these information signature of candidate, thumb impression, photo is taken on the sheet so that admit card may be generated.
Thumb impression is use full for biometric entrance in examination hall or for physical verification in physical test. In case of answer sheet, in addition to the above information, number questions in multiple choice, are given on the Omr Sheet.
If, the Omr sheet is designed for marketing survey, then the questionnaire set may be given on the Omr sheet. Omr sheet is designed for numerous applications as this is the fastest mode of capturing the data. Except the Magnetic reader, the rest of Omr sheet is printed in drop out color like magenta, orange, green, blue.
Magenta color is preferred. Bubble in the Omr sheet may be taken either oval or circular shape. Bar- code or numbering is also optional, but is while collecting the data.
Omr sheet scanning is the fastest data collection system. Omr sheet has vast application like entrance examination, multiple questions, objective type questions, registration activity, admission activity, recruitment activity, survey, marketing survey etc.
Asked in Computer Hardware Is optical mark reader a process unit? No, OMR is not a process unit.Optical mark recognition OMR is an electronic method of gathering human-handled data by identifying certain markings on a document.
Usually the optical mark recognition process is achieved with the aid of a scanner that checks the transmission or reflection of light through the paper; places having markings will reflect less light than the blank paper, resulting in less contrasting reflectivity.
Optical mark recognition is also known as optical mark reading or, more commonly, by the brand name Scantron. Optical mark recognition technology extracts useful data from marked fields such as fill-in fields and checkboxes very quickly and with great accuracy. The most common use of OMR is in offices, academics and research departments where large numbers of hand-filled documents must be processed such as surveys, questionnaires, exams, reply cards and ballots.
A common example is the use of standardized forms in schools where students have to fill in a predefined mark on the sheet, serving as a mark for the optical mark recognition algorithm.

Please switch on the OMR machine yourself. The switch is located on the floor. The prime function of the OMR machine is to scan and capture the optical marks on the multiple choice scoring sheets, and save the data into an output file which you can use to perform further analysis. Steps :. Select "Application" and the type of Multiple Choice Sheet you are using e. The corresponding "Edit profile""Score profile" and "Conversion profile" will appear. To start a new data file, click the "Datafile" button on the top menu and specify the name of the output file.
When all forms have been read, click the " Stop " button and the system will save the data in the output file the deault file type is. Note: you may encounter the following Scan Tools popup window. Just click "Yes" to bypass it.
Select "2" to proceed with the "Data Analysis". Do not select "1" as this module is obsolete. For each set of MC questions, you have to setup a "template" file to enter the marking parameters.
Select option "1" and specify the name of the template file. The template file has a default file extension of " mem ". The parameters to enter are: Report title, the last choice of each question, the correct answer to each question, and the weighting allocation of each question. See sample screen below. Save this template file after entering all the parameters. If there is any mistake in entering the marking parameters say the correct answer for a particular questionyou can re-select option "1" in the Master Menu and specify the same filename.
If you do not wish to use a template file for scoring as described above, and just want a quick marking of the examination to get a total score for each student, then you can use the simplified method as described in this section.Optical mark recognition also called optical mark reading and OMR is the process of capturing human-marked data from document forms such as surveys and tests. They are used to read questionnaires, multiple choice examination paper in the form of lines or shaded areas.
Many traditional OMR devices work with a dedicated scanner device that shines a beam of light onto the form paper. The contrasting reflectivity at predetermined positions on a page is then used to detect these marked areas because they reflect less light than the blank areas of the paper. Some OMR devices use forms that are preprinted onto "transoptic" paper and measure the amount of light which passes through the paper; thus a mark on either side of the paper will reduce the amount of light passing through the paper.
In contrast to the dedicated OMR device, desktop OMR software allows a user to create their own forms in a word processor and print them on a laser printer.
Optical mark recognition
The OMR software then works with a common desktop image scanner with a document feeder to process the forms once filled out. OMR is generally distinguished from optical character recognition OCR by the fact that a complicated pattern recognition engine is not required. That is, the marks are constructed in such a way that there is little chance of not reading the marks correctly.
This does require the image to have high contrast and an easily recognizable or irrelevant shape. One of the most familiar applications of optical mark recognition is the use of 2 pencil HB in Europe bubble optical answer sheets in multiple choice question examinations. Students mark their answers, or other personal information, by darkening circles marked on a pre-printed sheet. Afterwards the sheet is automatically graded by a scanning machine.
In the United States and most European countries, a horizontal or vertical "tick" in a rectangular "lozenge" is the most commonly used type of OMR form; the most familiar application in the United Kingdom is the UK National lottery form.
The large "bubble" marks are legacy technology from very early OMR machines that were so insensitive a large mark was required for reliability. In most Asian countries, a special marker is used to fill in an optical answer sheet. Students, likewise, mark answers or other information by darkening circles marked on a pre-printed sheet.
What Is OCR And What Is It Used For?
Then the sheet is automatically graded by a scanning machine. Many of today's OMR applications involve people filling in specialized forms. These forms are optimized for computer scanning, with careful registration in the printing, and careful design so that ambiguity is reduced to the minimum possible.
Due to its extremely low error rate, low cost and ease-of-use, OMR is a popular method of tallying votes. OMR marks are also added to items of physical mail so folder inserter equipment can be used. An optical answer sheet or bubble sheet is a special type of form used in multiple choice question examinations. Optical mark recognition is used to detect answers. The most well known company in the United States involved with optical answer sheets is the Scantron Corporationalthough certain uses require their own customized system.
Optical answer sheets usually have a set of blank ovals or boxes that correspond to each question, often on separate sheets of paper. Bar codes may mark the sheet for automatic processing, and each series of ovals filled will return a certain value when read. In this way students' answers can be digitally recorded, or identity given. The first optical answer sheets were read by shining a light through the sheet and measuring how much of the light was blocked using phototubes on the opposite side.
Because of this, number two pencils had to be used to fill in the bubbles— graphite is a very opaque substance which absorbs or reflects most of the light which hits it. Modern optical answer sheets are read based on reflected light, measuring lightness and darkness. They do not need to be filled in with a number two pencil, though these are recommended over other types this is due to the lighter marks made by higher-number pencils and the smudges from number 1 pencils.
Black ink will be read, though many systems will ignore marks that are the same color the form is printed in. Most systems accommodate for human error in filling in ovals imprecisely—as long as they do not stray into the other ovals and the oval is almost filled, the scanner will detect it as filled in.
It is possible for optical answer sheets to be printed incorrectly, such that all ovals will be read as filled. This occurs if the outline of the ovals is too thick, or is irregular. During the U. The slight difference was not apparent to the naked eyeand was not detected until a test run was made in late October.
