“Like other channels, touch has its own characteristics. It provides a rapid, immediate and powerful means of contact though mutual bodily interconnection. Easier to locate than sound and smell, it is specific and direct, works equally well in noisy conditions and, unlike vision, in the dark.
Multiple dimensions can be detected through touch, from the identification of objects to shape, size, spatial properties, temperature, flexibility, movement and texture.
There are corresponding limitations. The corollary to the immediacy of touch is that, like audition, it is not lasting and in the main disappears without trace. It is slower and more cumbersome than vision for scanning a linear series and less effective than sound for getting round physical barriers or covering distance. With some exceptions, participants must be physically close to communicate through touch. “
