A keyboard overlay is a blank keyboard that can be programmed to represent specific input signals. It is commonly used in the fast food industry and can also refer to a virtual keyboard on a touch screen. The device consists of unmarked keys arranged in a grid formation, and labels can be used to guide the user. Each key can be assigned various functions and input types. Expensive keyboards may have small screens on each key to display its function.
A keyboard overlay is a type of input device that consists of a tab with a series of keys on it that are typically unmarked and not assigned any particular meaning. It’s essentially a blank keyboard that can then be programmed so that each key represents a particular input signal. This type of device is often used in the fast food industry where each key can be assigned to a different food item, to make entry quick and easy. A keyboard overlay can also refer to a virtual keyboard that appears on a touch screen, allowing someone to enter input through it.
There are many different layouts and designs that can be used to create a keyboard overlay, although their functionality is essentially the same. This type of device typically consists of a number of keys that can be arranged in many different ways, placed on a base. The keys are often in a grid formation, in a square or rectangular assortment. They are also left blank since each of them is not inherently assigned to any particular letter, number or function. There are also some expensive keyboards that have small screens on each key, which can display that key’s function.
Several sheets of labels can be used with a standard keyboard overlay to guide the user to key features. These sheets are often called overlays, hence the name for this type of device. Individual stickers or labels can be used for each key, although more often a full sheet covers the entire overlaid keyboard. This allows the user of such a device to simply switch the paper when changing the input configurations for the device.
Each key on a keyboard overlay can be assigned a wide variety of different functions and input types, often limited only by the programming used with them. For example, engineers can use a keyboard like this to assign various functions commonly used in engineering software to the device. This can then make input quicker and easier, allowing the technician to use a key for a function that might require a combination of keys on a standard keyboard.
The term “keyboard overlay” can also be used to refer to a virtual input method that can appear on a touch-sensitive screen. Typically, this is a series of keys arranged similar to a standard keyboard that “overlays” the rest of the image on the screen. The user of this type of device can then use the touch sensitive screen and keyboard overlay to provide input.
