Grid-based selection tasks are interactive activities where users select items or options on a grid layout using a cursor. These tasks are designed to assess the efficiency and accuracy of cursor control, as users navigate through a two-dimensional space to make choices. They are especially relevant in studies involving brain-computer interfaces, as they allow for an evaluation of how effectively individuals can control their movements and select desired targets.
