The ability to localize an object moving in three dimensions without the need for sight can lead to improve spatial awareness and invoke novel experiences. While haptic shear stimulus has been shown to be capable of presenting both mobile and static two dimensional stimuli which can be localized, the presentation of depth using this approach has not yet been investigated. Herein, we propose and evaluate an algorithm for using a rotational skin shear deformation display to present stimuli which can allow one to proprioceptively localize a stimulus source in three dimensions. In the evaluation experiments, we first presented visual stimuli through a Head Mounted Display and then tactile stimuli through the proposed algorithm. The relationship between depth perception, recognition of depth orientation and the range of tactile stimuli was investigated.
