Mark sense

Mark sense refers to a technology used primarily in applications for data collection, particularly in environments like surveys, examinations, and multiple-choice tests. The term is often associated with optical mark recognition (OMR), which is a process that detects marks (e.g., pencil marks, pen marks) made on specially formatted paper forms. In a mark sense system, users fill out forms by marking their answers in designated areas, often using a specific marking instrument, such as a pencil or a black pen.
