What happens when the Ruby2 touchscreen is blocked by an object like a post-it note?

When a Ruby2 touchscreen is blocked by an object such as a post-it note, the interface relies on touch sensitivity to detect user input. If the screen is obstructed, the touch sensors cannot accurately register any touches or gestures, resulting in a non-responsive state. This means the screen will not respond to user commands until the obstruction is removed. This functionality ensures that unintended touches or actions do not occur if the screen is accidentally covered. Therefore, the correct answer highlights the necessity of having an unobstructed screen for proper interaction with the device.
