Inaccessible Design?

Just a thought—Accessible design, or design that adheres to accessibility standards and guidelines can often have a kind of clinical feeling, lacking any kind of texture. However, as we’ve learned from our visits to St Michael’s—it is often tactile sensation that has the biggest impact on some of the service users. Could the use of texture, or even the appearance of texture, create a more accessible kind of design in this case?
