Humming Interface

A human-computer interaction method that uses hummed pitch patterns as control signals for operating devices. In a humming interface, a pitch detection algorithm analyses the user's hummed input, segments it into discrete notes based on pitch contour (rising, falling, or flat), and maps sequences of notes to specific commands. Humming interfaces are a form of subvocal input that offer several advantages for accessibility: humming is easier to produce than speech and is possible even without vocal folds, it requires less computational power to process than speech recognition, it is independent of language and accent, and it can be performed nearly silently using bone-conduction microphones, making it unobtrusive in social settings.
