Our results demonstrate that audio timing through voice commands and haptic timing through tactile cues on the hand are alternative techniques to measure the SoA using the IB paradigm. ...
However, these adaptations remain within visual cues on-screen. Therefore, in this paper, we propose a set of timing stimuli that employ auditory and tactile cues. ...
