Capacitive Touchscreen

A capacitive touchscreen is a type of display that detects touch input by sensing changes in the electrical field caused by the conductivity of a human finger or conductive stylus. Unlike resistive touchscreens that require physical pressure, capacitive screens respond to the slightest finger contact, which creates significant accessibility challenges for blind users who cannot explore the screen layout without accidentally activating interface elements. Capacitive touchscreens are now the dominant technology in smartphones, tablets, public kiosks, appliances, and payment terminals, making their inaccessibility a widespread barrier for people with visual impairments.
