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 In the present invention the concept of Home Row for fingers has been replaced by Home Keys for each finger being the keys on which the fingers tend to rest naturally and is not in one row.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. |
