A whiteboard (also known by the terms marker board, dry-erase board, dry-wipe board, and pen-board) is a glossy, usually white surface for making non-permanent markings. Whiteboards are analogous to blackboards, but with a smoother surface allowing for rapid marking and erasing of markings on their surface. The popularity of whiteboards increased rapidly in the mid-1990s and they have become a fixture in many offices, meeting rooms, school classrooms, public events and other work environments.
The term whiteboard is also used metaphorically in reference to features of computer software applications that simulate whiteboards. Such "virtual tech whiteboards" allow one or more people to write or draw images on a simulated canvas. This is a common feature of many virtual meetings, collaborations, and instant messaging applications. The term whiteboard is also used to refer to interactive whiteboards.
Photographer Martin Heit and Alliance employee Albert Stallion have been credited with the invention of the whiteboard. [1] [2]
Whiteboards became commercially available in the early 1960s, but did not become widely used until 30 years later. Early whiteboards needed to be wiped with a damp cloth and markers had a tendency to leave marks behind, even after the board was erased. [2] [3] Dry-erase markers for whiteboards were invented in 1975. [2]
Whiteboards began being commonly used by businesses in the early 1990s. [4] They became more common in classrooms during the 1990s due to concerns over health problems in children with dust allergies and the potential for chalk dust to damage computers. By the late 1990s, about 21% of American classrooms had converted from chalkboards to whiteboards. [5]
The first whiteboards were very expensive and were made of an enameled steel. Cheaper versions were then produced, including laminated chipboard, high-pressure laminates and steel boards with a matte-finished or glossy white, usually polyester or acrylic, coating. Enameled whiteboards, also referred to as porcelain and sometimes glass boards, have the advantage that markings can be erased completely; other materials tend to become stained over time. Enameled boards are more expensive and less used in commercial environments, but in more demanding environments with heavier use, such as educational establishments, porcelain boards are considered superior.
Other types of dry marker boards are also available, such as high gloss vinyl and coated paper, which can be rolled up, high-density two-part high gloss paints, glass and coated acrylics and polypropylene magic whiteboards which use static electricity to cling to walls, windows, and doors.
Clear marker surfaces, made of glass (matte or glossy) or specially coated acrylic, became available around the mid-2000s. They are generally manufactured from technical glass, e.g. for monitor screen filters, which is optically coated.
Whiteboard material can be bought in rolls, sheets, and pre-formed boards. Adhesive whiteboards come in either a sheet or a roll and feature a stick back enabling the user to create a custom size board or project with the material. Although adhesive whiteboard material does not come in a thick, hard glass or painted steel plate, the melamine allows for a flexible material while preserving the high-quality whiteboard attributes of other surface materials. [6] Adhesive whiteboards allow for custom projects such as dry erase wall calendars, whiteboard tables, cupboard grocery lists, indoor games for kids, and more. [7]
One type of whiteboard pen (also called a whiteboard marker or dry erase marker) was invented by Jerry Woolf of Techform Laboratories and later patented by Pilot Pen in 1975. [8] It is a non-permanent marker and uses an erasable ink that adheres to the writing surface without binding to or being absorbed by it. Applications range from temporary writing with acetate sheets (for use with overhead projectors) to whiteboards and similar glossy surfaces. The erasable ink does not contain the toxic chemical compounds xylene and/or toluene, unlike permanent markers.
There are six types of materials commonly used for whiteboard surfaces:
Paint is a material or mixture that, when applied to a solid material and allowed to dry, adds a film-like layer. As art, this is used to create an image or images known as a painting. Paint can be made in many colors and types. Most paints are either oil-based or water-based, and each has distinct characteristics.
A printed circuit board (PCB), also called printed wiring board (PWB), is a medium used to connect or "wire" components to one another in a circuit. It takes the form of a laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with a pattern of traces, planes and other features etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive substrate. Electrical components may be fixed to conductive pads on the outer layers, generally by means of soldering, which both electrically connects and mechanically fastens the components to the board. Another manufacturing process adds vias, drilled holes that allow electrical interconnections between conductive layers.
A blackboard or a chalkboard is a reusable writing surface on which text or drawings are made with sticks of calcium sulphate or calcium carbonate, known, when used for this purpose, as chalk. Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone.
Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C. The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word vitreous comes from the Latin vitreus, meaning "glassy".
In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst. Heat is not necessarily applied externally, and is often generated by the reaction of the resin with a curing agent. Curing results in chemical reactions that create extensive cross-linking between polymer chains to produce an infusible and insoluble polymer network.
An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives.
A marker pen, fine liner, marking pen, felt-tip pen, felt pen, flowmarker, sign pen, vivid, flomaster, texta, sketch pen, koki or simply marker is a pen which has its own ink source and a tip made of porous, pressed fibers such as felt. A marker pen consists of a container and a core of an absorbent material that holds the ink. The upper part of the marker contains the nib that was made in earlier times of a hard felt material, and a cap to prevent the marker from drying out.
A permanent marker or indelible marker is a type of marker pen that is used to create permanent or semi-permanent writing on an object.
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a layered object or material assembled using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used.
Laser engraving is the practice of using lasers to engrave an object. The engraving process renders a design by physically cutting into the object to remove material. The technique does not involve the use of inks or tool bits that contact the engraving surface and wear out, giving it an advantage over alternative marking technologies, where inks or bit heads have to be replaced regularly.
Masking tape, also known as painter's tape, is a type of pressure-sensitive tape made of a thin and easy-to-tear paper, and an easily released pressure-sensitive adhesive. It is available in a variety of widths. It is used mainly in painting, to mask off areas that should not be painted.
An interactive whiteboard (IWB), also known as interactive board, interactive display, interactive digital board or smart board, is a large interactive display board in the form factor of a whiteboard. It can either be a standalone touchscreen computer used independently to perform tasks and operations, or a connectable apparatus used as a touchpad to control computers from a projector. They are used in a variety of settings, including classrooms at all levels of education, in corporate board rooms and work groups, in training rooms for professional sports coaching, in broadcasting studios, and others.
A primer or undercoat is a preparatory coating put on materials before painting. Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.
Coated paper is paper that has been coated by a mixture of materials or a polymer to impart certain qualities to the paper, including weight, surface gloss, smoothness, or reduced ink absorbency. Various materials, including kaolinite, calcium carbonate, bentonite, and talc, can be used to coat paper for high-quality printing used in the packaging industry and in magazines.
Substrate is a term used in materials science and engineering to describe the base material on which processing is conducted. Surfaces have different uses, including producing new film or layers of material and being a base to which another substance is bonded.
Melamine resin or melamine formaldehyde is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde. In its butylated form, it is dissolved in n-butanol and xylene. It is then used to cross-link with alkyd, epoxy, acrylic, and polyester resins, used in surface coatings. There are many types, varying from very slow to very fast curing.
Automotive paint is paint used on automobiles for both protective and decorative purposes. Water-based acrylic polyurethane enamel paint is currently the most widely used paint for reasons including reducing paint's environmental impact.
A fabric structure is a structure made of fabric, with or without a structural frame made from the weaving of the fabric itself. The technology provides end users a variety of aesthetic free-form building designs. Custom-made structures are engineered and fabricated to meet worldwide structural, flame retardant, weather-resistant, and natural force requirements. Fabric structures are considered a sub-category of tensile structure.
Industrial porcelain enamel is the use of porcelain enamel for industrial, rather than artistic, applications. Porcelain enamel, a thin layer of ceramic or glass applied to a substrate of metal, is used to protect surfaces from chemical attack and physical damage, modify the structural characteristics of the substrate, and improve the appearance of the product.
