Ergonomic contribution to keyboard design.

Modernized Latvian Ergonomic Keyboard

Increasingly more people use computers and create content using keyboards (even with leading edge touch-screen technology). As in the most part of the world, in Latvia also conventional "Qwerty" keyboard is used. Though for Latvian it is much worse than for English, especially due to enormous load to little fingers. It causes repetitive strain injuries and affects productivity of workers with e...

Ergonomic Principles Applied to the Design of the Microsoft® Office® Computer Keyboard

Ergonomic principles of human performance and human-machine interaction are applied to the design of a new, commercially available computer keyboard. Even though it is a primary means to connect people with computer applications, the keyboard has remained relatively static in design. This paper describes concepts and features implemented on a new computer keyboard, addressing negative performan...

An Ergonomic Model of Keyboard Fingering for Melodic Fragments

The fingerings used by keyboard players are determined by a range of ergonomic (anatomic/motor), cognitive, and music-interpretive constraints. We have attempted to encapsulate the most important ergonomic constraints in a model. The model, which is presently limited to isolated melodic fragments, begins by generating all possible fingerings, limited only by maximum practical spans between fing...

Design of Urdu Virtual Keyboard

This paper presents the first ever virtual keyboard layout based on character frequency analysis of Urdu Corpus. To optimize the keyboard layout Monte Carlo Simulation with simulated annealing is used. Furthermore, the proposed keyboard layout is augmented with word prediction list derived from Urdu corpus to speed up text entry. Performance analysis of keyboard layout is done for justification...
