We propose a psychophysical experiment aiming at investigating the differential sensitivity of the visual and haptic channels in view of the design of a novel perception-driven watermarking technique. A very simple stimulus is presented to the subjects that sense it either visually or the haptically. A noise sensitivity paradigm is followed to estimate the detection threshold of the embedded watermark. The characterization of the differential sensitivity of the two perceptual channels in a typical visuo-haptic rendering set up is aimed at determining which of the two considered sensory channels (namely vision and touch) sets the boundary for the detectability of the watermark for given rendering conditions.

Is haptic watermarking worth it?

Abstract

We propose a psychophysical experiment aiming at investigating the differential sensitivity of the visual and haptic channels in view of the design of a novel perception-driven watermarking technique. A very simple stimulus is presented to the subjects that sense it either visually or the haptically. A noise sensitivity paradigm is followed to estimate the detection threshold of the embedded watermark. The characterization of the differential sensitivity of the two perceptual channels in a typical visuo-haptic rendering set up is aimed at determining which of the two considered sensory channels (namely vision and touch) sets the boundary for the detectability of the watermark for given rendering conditions.
