Which of the following devices is primarily designed for text input?

The keyboard is primarily designed for text input as it consists of a set of keys that correspond to letters, numbers, and various symbols. This layout allows users to type efficiently, making it the most effective tool for entering text into computers and other devices.

While a touchscreen can also facilitate text input through on-screen keyboards or character recognition, it is not exclusively designed for this purpose and offers a broader range of functionalities, including touch gestures for navigation and control. Graphics tablets are primarily aimed at drawing and design rather than text entry, utilizing a stylus for precise control in artistic applications. Joysticks, on the other hand, are designed primarily for navigation and control in gaming and simulation environments, not for inputting text.

Thus, the keyboard stands out as the dedicated device meant for entering textual data, highlighting its essential role in typing and data entry tasks.
