Ympyrävalikko

Ympyrävalikko, also known as a radial menu or pie menu, is a graphical user interface element that presents options in a circular layout. When a user activates a ympyrävalikko, typically by holding down a mouse button or performing a specific gesture, a set of menu items appears arranged in a fan-like pattern around a central point. Each option is often represented by an icon or a short text label.

The primary advantage of ympyrävalikot is their efficiency. By arranging options in a radial fashion, users can often access frequently used commands with fewer mouse movements compared to traditional linear menus. This is particularly beneficial in applications that require rapid execution of commands, such as in gaming, 3D modeling, or graphic design software. The circular arrangement can also be more intuitive for certain actions, as it mimics natural hand or pointer movements.

Ympyrävalikot are activated by a specific user input, such as a click-and-hold action or a contextual gesture. Once activated, the user then moves their cursor or touch point towards the desired menu item. Releasing the input button or completing the gesture selects the chosen option. The design of ympyrävalikot often emphasizes simplicity and clarity, with a limited number of options to avoid overwhelming the user.
