Keyboard Arrangement
The present invention relates to a keyboard arrangement.
According to the invention, there is provided:
i) a keyboard having a plurality of keys or pads provided with respective indicium symbols; and,
ii) an overlay for at least some of the keyboard keys or pads, the overlay including finger touch zones configured to overlay respective predetermined keyboard keys or pads, the finger touch zones being marked with indicia different to the indicium symbol on the underlaying keyboard key or pad.
The keyboard is preferably electronic keyboard such as an alphanumeric keyboard (for example a computer or wordprocessor keyboard) and preferably at least some of the keys or pads are preferably marked with alphanumeric indicia.
In one embodiment of the present invention the keyboard keys or pads are provided with respective upper case letter indicium symbols and at least some of the finger touch
zones are marked with a respective lower case letter indicium symbol corresponding to the underlying upper case letter indicium symbol on the keyboard key or pad. Furthermore, groups of finger touch zones are commonly colour coded to correspond with groups of selected keys or pads on the underlying keyboard having a particular related or common characteristic or function.
The overlay preferably covers substantially the entire keyboard.
Desirably, the overlay comprises a sheet of flexible resilient material, preferably a sheet of plastics material such as, for example polyvinyl chloride.
The overlay may comprise a sheet of moulded material, particularly where the keyboard comprises depressible key elements. In this embodiment, the overlay may have shaped moulded finger touch zones arranged to encompass individual respective key elements.
The indicium carried by a respective finger touch zone may be an identifiable symbol (such as an alphanumeric character) or a colour indicium or a combination of both.
Typically electronic alphanumeric keyboards include depressible keys or finger touch actuatable pads. Typically the 'letter' keys or pads are provided with markings in upper case. When teaching young children to use such a keyboard it is believed that it would be useful
to provide 'letter' markings in lower case. The invention provides that by providing a lower case letter indicium on the respective finger touch zone of the overlay corresponding to the underlying upper case letter symbol on the keyboard key or pad, a standard keyboard can be adapted to aid in teaching young children keyboard skills.
In one embodiment the overlay may include a plurality of commonly coded finger touch zones. Common coding of finger touch zones may be achieved, for example by having a predetermined selection of finger touch zones commonly coloured to identify a particular common characteristic. For example all letter keys may be coded in a first colour, all numeric keys in a second colour, 'arrow' keys in a third colour, and 'function' keys in a fourth colour. Groups of finger touch zones may therefore be commonly coded to correspond with groups of selected keys or pads on the underlying keyboard .
In certain instances a respective finger touch zone may be marked with two or more indicia, one or both of which will be different to the indicium symbol on the underlaying keyboard key or pad.
The respective finger touch zones are preferably substantially opaque, such that the symbol on a respective underlying keyboard key or pad is not visible when the overlay is in place in register with the keyboard.
Desirably, the overlay includes one or more substantially
rigid zones arranged to overlay predetermined selected keyboard keys or pads. In this way certain keyboard keys or pads (such as command keys) can be inhibited from actuation.
In one embodiment, the overlay may comprise a plurality of layers, respective layers comprising a sheet of flexible resilient material and including finger touch zones configured to overlay respective predetermined keyboard keys or pads, the finger touch zones on each layer being marked with indicia different to the indicium symbol on the underlaying keyboard key or pad. The finger touch zones of successive layers are advantageously marked with different respective indicia.
In one embodiment, the arrangement may comprise a displacable cover portion (such as for example a hinged cover panel) carried by the overlay, and displacable from a cover position (in which access to certain keyboard keys is inhibited) to a displaced position in which access to the relevant keys is permitted.
The invention will now be further described in a specific embodiment by way of example only, and with reference to the accompanying drawings, in which:
Figure 1, is a plan view of an exemplary keyboard arrangement according to the invention; and,
Figure 2, is a plan view of an alternative keyboard
arrangement according to the invention.
Referring initially to figure 1, a conventional computer keyboard (not shown) is provided with an overlay cover 1 comprising a sheet of substantially flexible opaque plastics material moulded to conform to the shape of an upper surface of the keyboard. The surface of the cover overlay 1 is provided with demarked finger touch zones 2 carrying respective indicia in the form of lower case lettering thereon. The lowercase lettering corresponds to upper case lettering provided on the keyboard keys underlying the cover overlay 1. Therefore, when the cover ,1 is placed on a conventional keyboard for a computer, the lowercase lettering is superimposed on the corresponding upper case lettering present on a keyboard. Furthermore, zones corresponding to the "space bar", "shift", "enter" and "back space" are provided labelled "space bar" , "shift" "enter" and "back space" .
The finger touch zones 2 are further marked with colour indicia in the form of being colour coded in respective groups such that preselected groups of keyboard keys underlying the cover overlay 1 correspond to respective colour coded groups of finger touch zones. For example, the row of numerical keyboard keys may be overlaid with red finger touch zones; the letter keys may be overlaid with blue zones and the arrow keys may be overlaid with green zones .
In the modification to the cover overlay 1 shown in figure
2 , each finger touch zone of the cover overlay 1 overlaying the alpha numeric portion of the keyboard is marked with two characters (For example upper and lower case characters) and additionally is two-tone colour coded, such that the character produced by depressing the relevant key when the 'shift' key is also depressed is backed by a colour corresponding to the colour of the "shift" finger touch zone .
The invention enables a standard keyboard to be adapted to aid in teaching young children keyboard skills by making the correlation between groups of keys and function more clear, and also by presenting alphanumeric characters in a more recognisable form for young children (i.e. lower case) .
It will be appreciated that other colour coding and indicia correlation arrangements can be utilised without departing from the essence of the invention.
