A user reports that the new touch pen they bought for their modern smartphone does not work on an older, industrial-grade tablet. Which of the following is the MOST likely reason for this incompatibility?
The touch pen requires a Bluetooth connection to pair with the device, which the tablet lacks.
The tablet's operating system is outdated and does not support modern touch pen accessories.
The touch pen is designed for a capacitive screen, while the tablet likely has a resistive screen.
The tablet's screen is not calibrated correctly for pen input.
Modern smartphones use capacitive touchscreens, which require a conductive object like a finger or a capacitive pen to interact with their electrostatic field. Older or rugged industrial tablets often use resistive touchscreens, which rely on physical pressure to register a touch by pressing two layers of the screen together. A pen designed for a capacitive screen will not work on a resistive screen because the underlying technologies are incompatible; one relies on conductivity, and the other on pressure.
