This paper introduces a novel adaptive direction filtering algorithm in the Vocal Joystick (VJ) setting that utilizes context information and applies real-time inference in a continuous space. The VJ system using this algorithm is endowed with the ability to produce movements in arbitrary directions and the ability to draw smooth curves. This is in contrast to previous VJ settings whereby vowel quality was used to determine mouse movement in only a finite discrete set of directions [1].
