The Libri GmbH The New Data Entry Device for Computers

Keyboard of the FutureDesigned for comfort. Engineered for speed. A frequency-based, ergonomically optimised solution for human-computer interaction.This book unveils the Data Entry Device for Computers (DED), a transformative keyboard design that aligns digital input with the human anatomy.The DED replaces the legacy QWERTY layout, a 19th-century keyboard designed in the 1870s, intended to slow down typists to match the limitations of mechanical typewriters of the time. The DED is developed for today's technology and needs, using foundational principles of ergonomics, anatomy, and frequency-based logic. Combining rigorous scientific method with personal insight, this volume presents a compelling work in user-centred design and optimised performance. The result is a data entry device that is faster, more efficient, and significantly more comfortable, meeting the demands of the digital age.This work is an indispensable academic resource for students and professionals in Human-Computer Interaction (HCI), Product Design, Ergonomics, and Computer Science. Its structured approach equips the next generation of designers and researchers to challenge legacy systems and design better ones.The DED has been granted patents in the United States, China, and India.
