Grid-Based Cursor Control

A hands-free cursor positioning technique that overlays a numbered grid on the screen, allowing users to select a cell by voice command or other input to recursively zoom into smaller screen regions until the desired target is reached. Grid-based approaches reduce the vocabulary needed for speech-controlled cursor movement and use discrete commands rather than continuous directional navigation, making them more robust against recognition errors. This technique is particularly useful for people with motor impairments who cannot use a mouse.
