An interactive whiteboard that utilizes touch detection for user input is commonly referred to as a whiteboard. This type of technology enables users to engage with the board directly through touch, facilitating a more dynamic and participatory learning environment. Interactive whiteboards often serve as a focal point in classrooms or meeting spaces, allowing for the display of digital content and the ability to manipulate that content in real-time.

The term "whiteboard" specifically refers to the surface on which users can write, draw, and interact with applications using their fingers or styluses. This interactivity enhances the teaching and learning process by allowing for immediate feedback and collaboration among participants.

In contrast, "hot touch" is not a recognized term in the context of interactive technology, nor does it specifically refer to whiteboards. "Green board" typically refers to traditional chalkboards, which do not have interactive digital features. A "tablet computer," while also touch-sensitive and used for input, is a portable device rather than a large, interactive display meant for group settings. Therefore, the designation of an interactive whiteboard as a whiteboard aligns with the commonly accepted terminology in educational and professional environments.
