The design of a wearable tactile array which can exploit the funneling illusion in two dimensions

Abstract

The goal of this research was to create a wearable tactile array that is capable of exploiting the funneling illusion in two dimensions. The design process is explored in detail, including the formulation of the design requirements, the materials that were trialed, the electronics design iterations, and the development of a software development kit (SDK) which includes a novel algorithm for rendering both the static funneling illusion and dynamic funneling illusion. The ability of the algorithm to render overlapping circle and square stimuli at discriminable levels is experimentally tested demonstrating its efficacy in this task.
