![]() This led to research on how the lecturer/teacher could directly change the information in the projection screen without physically touching the computer. ![]() Because most teachers/lecturers used PowerPoint (PPT) presentations, it was convenient for them to connect the computer to an overhead projector which would project the computer screen onto a large fabric, whiteboard, or white wall surface, which served as the projection screen.Įven so, the user could only change the information on the projection screen by typing into the computer the required data. In lecture halls and classrooms, the whiteboard needs to be large so that everyone can see the information. Later, the capabilities to draw and write directly onto the touchscreen using a special type of pen allowed users to draw and write on whiteboards as natively as if they were doing it on a hardcopy paper. ![]() In the 2000s, the touchscreen which combined an input device with the computer visual display into a unified information processing system had been developed, and this allowed users to use their fingers as the mouse, as well as to press on the onscreen keyboard input information into the whiteboard applications. This was also the era of the computer and internet revolution and contemporaneous innovation led to development of collaborative applications called whiteboards which used the white space of text applications as a canvas where users could write, edit, and share information. In the late 1980s and early 1990s, the whiteboard had become a popular fixture in offices. This created a challenge as some markings remained visible after erasing, and this led to the development of dry-erase markers in 1975 which allowed for better erasure of whiteboard markings. ![]() Uniquely, the markings in these early whiteboards were erased by damp cloths, while blackboards were wiped clean by dry cloth dusters. Moreover, whiteboards require one to use a marker pen instead of a blackboard chalk, and it for this reason that it is known as a pen-board. They have remained popular due to their ability to provided a smooth surface where non-permanent markings could be made, and erased easily.Įven so, the whiteboard has a white surface that is smoother and glossier than that found on the black surface of the blackboard. It was replaced in the 1950s by the whiteboard.Īt this time, both the blackboard and the whiteboard were known as marker boards, wipe boards, dry-erase boards, and dry-wipe boards (we now also have sophisticated paint mixtures to create dry-erase walls).
