Current keyboards are sequential, requiring one key to be pressed before another, which is seen as inefficient. The concept of a Parallel Keyboard proposes allowing multiple keys to be pressed simultaneously, enabling faster typing speeds by eliminating the need for sequential input. While proponents argue this could lead to typing speeds over 200 WPM, critics highlight the challenges of accurately determining intended words from simultaneous key presses, especially with common letters and potential ambiguities. Additionally, the cognitive load of thinking in terms of multiple letters at once may hinder usability. Overall, the practicality of such a keyboard remains debated, with concerns about efficiency and user adaptability.
