The very first touchscreen concepts, developed in the 1960s, were intended for air traffic control. These early systems demonstrated how direct screen interaction could improve the efficiency and accuracy of complex tasks, long before the technology became commercially available to the general public.
In 1983, the HP-150 introduced a touchscreen as one of the first commercial computers. The system used an infrared grid in front of the screen to detect the position of a finger. This was an early step in incorporating touch interaction into computing, even before the advent of capacitive screens.
In the 1990s, devices such as the Apple MessagePad and the Palm Pilot brought touchscreens to the consumer market. These Personal Digital Assistants (PDAs) primarily used resistive touch screens operated with a stylus. They laid the foundation for mobile devices with direct screen interaction.
The launch of the iPhone in 2007 was a turning point. It introduced a highly accurate and affordable multi-touch capacitive screen that made finger operation intuitive. This set the standard for the modern smartphone industry and ensured the widespread adoption of touchscreen technology.
An early form of touchscreen technology that works by physical pressure. Two conductive layers are pressed against each other, which registers a touch. This technology was cost-effective and was widely used in PDAs and navigation systems, often operated with a stylus.
This technology, developed at CERN in the 1970s, detects touch via the disruption of an electrostatic field, using the conductivity of the human body. It requires no pressure and is more durable. Projected Capacitive (PCAP) has become the modern standard.
Used in early devices such as the HP-150. This method places a grid of infrared LEDs and photodetectors around the edge of the screen. A finger approaching the screen interrupts the rays, determining coordinates without physically touching the screen.
A crucial innovation that enables the simultaneous detection of multiple touch points. Popularized by the iPhone, multi-touch enables intuitive gestures such as pinch to zoom ('pinch-to-zoom'). This has fundamentally changed the user experience on smartphones and tablets.
At Dytos, we understand that each industry has specific requirements for touch solutions. That's why we offer a wide range of products and services designed to meet these diverse needs.
