N1 - This peer-reviewed paper published in European Psychologist, reports on an experimental study investigating a novel, theoretically-motivated design for constructing tactile pictures for the blind (the TexyForm system), developed by the first author. The system tackles the complex and neglected problem of presenting 3D information in a 2D form, in a meaningful way for those with little or no visual experience and hence limited understanding of pictorial perspective. The TexyForm design was based on experimental research on 3D haptic object recognition in blind and sighted people, in order to enable stimulus input to more easily match existing internal representations of objects. In addition to practical design applications, the work adds to the debate surrounding blind people's understanding of perspective and contributes to the literature on haptic perception by experimentally testing a novel theory of 3D haptic object recognition proposed by the authors.
