Isotropy and visual modulation of haptic force direction discrimination on the human finger

In this review, we summarize the findings from two recent studies that have investigated haptic force direction discrimination thresholds in adult humans. Haptic force vectors originating from one of five different force directions were presented to the index finger of participants. Discrimination thresholds were measured using a three-interval one-up threedown adaptive procedure. In contrast to the literature on the anisotropy of haptic perception, the results of the two experiments suggest that the acuity of the haptic perception of force direction is not directionally dependent. This review paper also examines the relative contributions of haptic and visual information to the generation of coherent multisensory percepts.
