![]() This back-and-forth oscillation between vowels and consonants perpetuates in sentences. Words are typed in a natural alternating way moving between vowels and consonants. No one way suits all languages and/or user preferences. A similar approach could be undertaken to match other languages. A foundation can be constructed for an efficient keyboard arrangement with this information. This small group of words is probably the most used in everyday typing activity, comprising English-speaking sentences worldwide. The basis of such language starts with pronouns (I, you, he, she, it, we, and they), followed by the primary verbs (be, do, and have). The English language (for example) has more than 200,000 words, with a minimum of 3,000 words required for effective communication. ![]() CC BY-SA 2.0) The oscillatory flow within words Moving our arms instead of our fingers makes us slower and tire more quickly. The amount of effort required to exercise these degrees of freedom increases as one moves from the fingers to the arm simply because of the increased mass that is displaced. The hand (including fingers) can be rotated about the wrist, and the arm, in turn, can translate (including the hand and fingers) from front to back and side to side. The natural geometry of a hand and fingers comprises a center at the palm with a combination of fanning-out fingers, which can be radially extended. What is the effort impact on a full day of typing?.Do I want to move my fingers, hands, arms, or a combination of all?.How do typing the words and recurrence affect the key layout?.What are the words that I most often use?.How does the mind construct any given word, and how do I type the letters to do so?.What is the easiest and most effortless way to place a word on a screen?. ![]() In turn, a keyboard interfaces with a person, making the following questions pertinent during its design: For example, a jet engine interfaces with an aircraft. Ergonomic reflectionĪny design starts with an adequate understanding of the system's dynamic with which the device interfaces. The idea presented here is just one possibility out of many.Ĭonsidering the potential benefits in terms of effort and time saved from a more efficient typing activity, multiplied by millions or even billions of users that type every day, the overall effect can yield a potentially colossal reward with a global impact on both social and professional activities. A critical question that still has no answer is, Is the current arrangement of keys on my keyboard the most efficient and intuitive solution, effortwise and timewise? This article hopes to kick off an exchange of ideas on fundamental out-of-the-box approaches to create novel and radical open source keyboard constructions that address this question. I believe that during the electrification of typewriters over the past century, the link between human physiology and the arrangement of the keys in a keyboard, as an interface between human and machine, has been mostly overlooked. Overall, this translates into more than 100 years of monumental evolution in how we transform typing action into printed or screen-perceived text (from human-powered to electrical-powered with advanced computing), but with little to no development of the human-to-machine interface (both in terms of its logic arrangement and ergonomic features).
