Alloesthesia is a rare clinical condition that corresponds to a spatial disorder of stimulus localization, in which patients experience a given stimulus on the side opposite to the side of stimulation. Whereas it has been mostly described for unisensory stimulations, evidence of multisensory alloesthesia is only anecdotal. Here, we investigated a case of multisensory auditory-tactile alloesthes...

As typical turn by turn systems fail in several aspects to provide an engaging experience to pedestrians in urban environments, we investigate the potential of alternative interaction methods for navigation. We present a two-phase experiment, involving both audio and tactile navigation and discuss the collected evaluation data. Our findings show a positive reception of implicit navigation from ...

In a previous work, we confirmed the existing effects of “Out of the Body” tactile illusion for virtual and augmented objects through funneling and saltation. However, it required a virtual imagery to be attached to the user for directly extending one’s body. This paper aims at investigating similar phantom tactile sensations exist when the virtual object is visually detached from the user’s bo...

Greek word haptikos (from haptesthai, to grasp or touch). For touch user interfaces, the term typically refers to a tactile sensation or force-feedback that users experience when touching the surface. Conventional touch screens do not provide the tactile sensation of mechanical buttons and knobs, resulting in a less satisfying experience. Haptics technology can reproduce the same feel or tactil...

This paper proposes a learning model that enables a robot to acquire a body image for parts of its body that are invisible to itself. The model associates spatial perception based on motor experience and motor image with perception based on the activations of touch sensors and tactile image, both of which are supported by visual information. The tactile image can be acquired with the help of th...
