Abstract

According to the Collingridge dilemma, technology is easy to control when its consequences are not yet manifest; once they appear, the technology is difficult to control. This article examines the development of keyboard layout design from the perspective of the Collingridge dilemma. For this purpose, unlike related studies that focus on a limited period of time, the history of keyboard development is explored from the invention of the typewriter and the QWERTY to brain–computer interfaces. Today, there is no mechanical problem of the typewriter for which the QWERTY was designed. On the other hand, better layouts have been designed for various situations so far, that can be easily implemented especially on virtual keyboards, but QWERTY has not been replaced. The present study shows how various factors as heterogeneous engineering have shaped QWERTY, prevented the prevalence of superior layouts, and led to Lock-in. Then, unlike other studies related to the Collingridge dilemma, which provide a qualitative description of it, a quantitative description is proposed that helps to better understand the Collingridge dilemma and Lock-in. Finally, the case study of the QWERTY keyboard illustrates that the theory of human-technology co-construction can provide a more comprehensive explanation of technology development, while the Collingridge dilemma can better provide some details of technology development.
