The Pioneering Work of Dr. G. Samuel Hurst

The story of resistive touchscreen technology begins in the early 1970s at the University of Kentucky, where Dr. G. Samuel Hurst was conducting his doctoral research, which involved nuclear physics experiments. Faced with the challenge of reading data from analog computer graphics displays more efficiently, Dr. Hurst conceived and developed the first practical resistive touchscreen in 1971.

Dr. Hurst’s original invention utilized two transparent conductive layers separated by microscopic spacer dots. When pressure was applied to the surface, these layers would make contact at the touch point, creating a measurable change in electrical resistance that could be converted into precise coordinate information. This pressure-based detection mechanism would become the fundamental principle underlying all future resistive touchscreen development.

In 1975, Dr. Hurst received the first patent for resistive touchscreen technology, officially documenting the innovative pressure-sensitive detection system that would revolutionize human-computer interaction. The patent described a touch-sensitive input device capable of detecting touch location through resistance measurement, establishing the technical foundation for decades of subsequent development.

Recognizing the commercial potential of his invention, Dr. Hurst founded Elographics in 1977 to develop and manufacture resistive touchscreen products. This company became the first commercial producer of resistive touchscreens, establishing the industry that would eventually serve countless applications across diverse markets.
