What is a key feature of resistive touch screens?

A key feature of resistive touch screens is their ability to register input from various objects. Unlike capacitive touch screens, which require a conductive material (like a finger) to operate, resistive touch screens consist of two layers separated by a small gap. When pressure is applied to the top layer, it makes contact with the bottom layer, registering the touch. This design allows users to interact with the screen using different objects such as a stylus, gloved fingers, or any other pointed item, not just a finger.

The other options describe features not typically associated with resistive touch screens. For instance, resistive screens do not utilize electric fields but rather rely on pressure to register input. They also do not require a warm object as they simply respond to physical pressure. Additionally, resistive touch screens have limited multitouch capabilities compared to capacitive screens, which are designed to handle multiple touch points simultaneously.
