What are interactive areas of a web page for touch device users called?

Tap targets are the designated interactive areas on a web page that are optimized for touch device users. These areas are specifically designed to be easily selectable with a finger, ensuring a smooth and user-friendly experience on touch screens. Tap targets must be large enough to accommodate the average touch, reducing the likelihood of users accidentally selecting the wrong element due to inadequate sizing.

While terms like hot zones, touch points, and clickable areas may refer to different aspects of interaction design, they do not specifically capture the nuance and best practices associated with touch screen interfaces. Hot zones might imply areas of increased interest or activity, while clickable areas can refer to any interactive space without the touch-specific considerations. Touch points can broadly refer to any interaction moment but do not necessarily focus on the design principles applicable to touch device usability. Hence, tap targets is the most appropriate term that encapsulates the essence of creating user-friendly interactive areas specifically for touch devices.
