Methodology for developing textures on friction based interfaces

The design of textures for so-called variable friction technologies requires multiple perspectives, which this paper aims to outline and discuss. We first propose a definition of texture and describe the current state of knowledge on their perception. After presenting two technologies for variable friction and comparing them to other tactile interfaces, we describe several particular uses for these devices (Figure 4 ). We then discuss psychophysical methods for signal perception evaluation and finally discuss methodologies for creating multidimensional tactile content [26] .
