We are interested in the haptic representation of auditory slopes. A diagonal line sonified is easy to recognise even if no conversion instructions are given to the participant. The degree of slope is dependent on the duration and frequency components of the sonified image and therefore with a small amount of training it is relatively easy to discriminate lines with a shallow gradient from steeper ones. We are interested in the cross-modal conveyance of slope angle i.e using a haptic input device (Falcon) will participants under or overestimate the degree of slope when transmitting the sonified information to a haptic response device? If using haptic devices to represent sounds or move between areas of interest in a soundscape a standardisation is required to adapt features of the device (resistance/ viscosity) and/or training protocols to ensure accurate performance.
