Which feature is commonly found in Lenovo tablets to enhance user interaction?

The feature commonly found in Lenovo tablets to enhance user interaction is the touch screen. Touch screens are integral to the user experience in tablets, providing a direct and intuitive way to interact with the device. They allow users to tap, swipe, and pinch to navigate the interface and access applications, making it easier to engage with content in a fluid manner.

This capability is particularly important for tablets, as they are designed for portability and user-friendly interaction without the need for additional peripherals like a mouse or keyboard. While other features such as an integrated keyboard, HDMI ports, or removable batteries may be useful in some contexts, they do not fundamentally alter the interactive experience in the same way that a touch screen does, which is vital for the operation and functionality of a tablet.
