Embodiment

[0115] Thus, the present invention provides a data entry device for enabling a user to enter data comprising a plurality of keys and a pointing device positioned on a keyboard such that the hands are not moved from the initial rest of the hands on the keyboard. All keys and pointing devices can be operated by repositioning the positions, and the plurality of keys and pointing devices are positioned to distribute the workload to the left and right hands according to their respective working capabilities relative to each other and are further positioned to Distribute the workload on each finger and thumb according to their relative working capabilities; the plurality of keys are divided into one or more groups, wherein at least one group includes The keys are positioned on the keyboard in order of their ease of use.

[0116] In one embodiment of the present invention, the one or more groups include a character key group or an operation key group or a technical function key group...

Abstract

The present invention provides a Data Entry Device for computers and other devices. An embodiment of the present invention provides a Data Entry Device combining a keyboard and pointing device for computers and other devices; The Data Entry Device of the present invention introduces a completely new ergonomic construction for all keys. In the Data Entry Device of the present invention the keyboard and pointing device can both be used without shifting the hands from its initial resting position and where the shift key has to be used only for capitals and a few rarely used punctuations and symbols. The vowels are all on one side thus making them easy to access and use. All the letters are arranged so that on maximum occasions the letters are alternating between hands. The character keys are separated into alphabets, numerals, mathematical operators, punctuations and symbols; The placement of the characters on the DED is based on their frequency of occurrence in the environment, the ideal workload that should be allotted to each finger, the order of ease of use of keys, their pattern of use and similarity of type. In the present invention the concept of Home Row for fingers has been replaced by Home Keys for each finger being the keys on which the fingers tend to rest naturally and is not in one row. All this together makes the DED easy to comprehend, easy to learn, easy to use, more difficult to forget, increase the speed of typing, reduce errors and makes the user less prone to medical problems.

Description

technical field [0001] The present invention relates to a data entry device, more particularly, the present invention relates to a keyboard for entering data and operating computers and other devices, and more particularly, the present invention relates to a keyboard having an ergonomic key configuration. Background technique [0002] Currently, the International Business Machines Windows Keyboard (IBMW Keyboard) is the standard keyboard for use with computers. The construction of this keyboard is followed by all manufacturers with minor variations depending on the additional features included and the specific field of use of the keyboard. [0003] The IBM W keyboard is a product that has evolved over time, and its design and keyboard construction were not conceptualized in a holistic way that took all aspects into account from the start. As a result, the construction of the IBMW keyboard is neither systematic nor logical and does not take several ergonomic aspects into con...
