Stephen Hawking, one of the most celebrated theoretical physicists of our time, was not only known for his profound contributions to science but also for his remarkable ability to adapt to severe physical constraints imposed by amyotrophic lateral sclerosis (ALS). As the disease progressed, Hawking increasingly turned to advanced technologies to assist with reading, writing, and communicating his groundbreaking ideas. This deep dive into how Hawking used technology reveals a powerful story of human ingenuity and determination.
Early Adoption of Assistive Technologies
As ALS took away Hawking’s motor functions, including speech and hand movements, his ability to perform simple tasks like reading and writing became nearly impossible. Recognizing the potential of emerging technologies, Hawking became an early adopter of various assistive devices. This not only allowed him to continue his academic work but also helped him communicate with the wider world.
Communication Systems
The cornerstone of Hawking’s technological arsenal was his speech-generating device (SGD). Initially, he controlled this device with a hand clicker. As his condition progressed, the technology evolved, and he started using a single infrared switch activated by movements of his cheek muscle. This switch was part of a sophisticated system developed by Intel, which included a word predictor to speed up communication.
The software attached to his SGD, called ACAT (Assistive Context-Aware Toolkit), allowed Hawking to perform tasks beyond verbal communication. It enabled him to browse the internet, write lectures, books, and papers, and even control the doors in his office.
Reading and Learning
For reading, Hawking used adaptive technologies that included screen reading software, which could read texts aloud from his computer or other digital devices. This software was crucial, particularly as his physical ability to handle books and papers dwindled.
Moreover, Hawking utilized voice commands and a switch scanning input system, which allowed him to select specific actions or items on his screen by scanning through them with a switch and performing a simple action with his cheek muscle to make selections. This setup facilitated him not just in reading academic papers and books but also in reviewing and editing his works.
Writing and Research
Writing was an area where technology truly transformed Hawking’s capabilities. Through his speech-generating device and later developments, he was able to compose text using predictive algorithms that anticipated words he might choose based on the first few letters and his past usage. This technology significantly reduced the number of movements needed to write lengthy documents, including his research papers and books like “A Brief History of Time.”
Hawking’s research method often involved extensive discussions with colleagues and students. Technology enabled these interactions even after he lost his speech. Video conferencing and direct communication through his SGD were integral in allowing him to continue collaborations and lead his research team effectively.
Legacy and Inspirations
Stephen Hawking’s use of technology redefined what scientists believed was possible under severe physical constraints. His willingness to embrace and even push for advancements in assistive technologies not only allowed him to continue his work but also raised awareness about the potential of such technologies to transform lives.
Hawking’s story is a testament to human resilience and the profound impact that technology can have on overcoming physical limitations. His life encourages ongoing research and development in assistive technologies, promising to open new avenues for individuals with disabilities across the globe.
