A software keyboard, also known as a virtual keyboard, is a digital interface that allows users to input text on devices like smartphones, tablets, and computers. Unlike physical keyboards, software keyboards appear on the screen and can be customized in size, layout, and language. They are essential for touch-screen devices where traditional keyboards are impractical. These keyboards typically include features like predictive text, autocorrect, and emoji support to enhance user experience. Software keyboards can adapt to different applications, providing specialized layouts for tasks such as gaming or coding. They are a crucial component of modern user interfaces, making text entry more accessible.
