Speech-Based Cursor Control

A method of controlling a computer's pointing cursor using spoken voice commands rather than a mouse, trackpad, or other physical pointing device. Users speak directional commands (such as "move left," "move up") to start cursor movement and a stop command to halt it, then issue a click command to select the target. Speech-based cursor control is an important assistive technology for people with motor disabilities who cannot use physical pointing devices, but it faces inherent challenges: recognition delays cause the cursor to overshoot targets, small targets are difficult to select accurately, and the interaction is significantly slower than mouse-based pointing. Two main approaches exist: direction-based navigation (continuous cursor movement in a specified direction) and target-based navigation (naming or identifying specific on-screen elements).
