Touchscreens are the standard interface for modern consumer devices such as smartphones and tablets. Direct touch control is essential to the user experience, from navigating apps to typing messages. GPS navigation systems in cars also make extensive use of this technology for easy route setting and feature control.
Many personal computers, especially all-in-one models and 2-in-1 laptops, are equipped with touchscreens for more flexible control. In the gaming world, touchscreens are used on handheld consoles and smartphones, where they allow immersive and direct control over the game, enriching interaction over traditional controllers.
In the retail and hospitality industries, touchscreens are indispensable for point-of-sale (POS) systems and cash registers. They enable fast and efficient transactions by providing an intuitive interface for order entry and payment processing. This simplifies the workflow for employees and reduces the risk of errors.
Automatic teller machines (ATMs) and information kiosks in locations such as airports and shopping malls use touchscreens for an accessible and user-friendly interface. Users can perform bank transactions, look up information or purchase tickets independently. This increases efficiency and provides users with 24/7 service without the need for staff.
Resistive touchscreens consist of two flexible, conductive layers. When pressure is applied, the layers make contact, causing a change in the electric field. This technology is cost-effective, durable and can be operated with any form of input (finger, stylus, glove), but has lower image clarity and sensitivity than newer technologies.
Capacitive displays, including PCAP (Projected Capacitive), use a conductive layer that responds to the electrical properties of human skin. A touch disrupts the electrostatic field, which is detected. This technology offers superior image quality, high sensitivity and multi-touch support, making it the standard for smartphones and tablets.
Surface Acoustic Wave (SAW) screens use ultrasonic sound waves moving across the screen surface. A touch with a soft object absorbs part of the wave, allowing the position to be determined. These screens offer excellent image clarity because there are no metal layers over the glass. However, they are vulnerable to dirt and water on the surface.
Infrared touchscreens work with a grid of invisible infrared LEDs and photo detectors along the edges of the screen. An object touching the screen interrupts the rays, registering the coordinates. This technology is very robust, can be operated with any object and is impervious to scratching the screen itself, making it suitable for public applications.
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.
