Users of optical see-through head-mounted displays (OHMD) perceive color as a blend of the display color and the background. Color-blending is a major usability challenge as it leads to loss of color encodings and poor text legibility. Color correction aims at mitigating color blending by producing an alternative color which, when blended with the(More)

It is easy for human beings to discern whether an observed acoustic signal is a direct speech, reflected speech or noise through simple listening. Relying purely on acoustic cues is enough for human beings to discriminate between the different kinds of sound sources which is not straightforward for machines. A robot equipped with the current robot audition(More)
Reverberation poses a problem to the active robot audition system. The change in speaker’s face orientation relative to the robot perturbs the room acoustics and alters the reverberation condition at runtime, which degrades the automatic speech recognition (ASR) performance. In this paper, we present a method to mitigate this problem in the context of the(More)
