Simulated textures whose parameters are held with object model data in a dat a store (5) are modified in accordance with data held in a data store (6) whic h data defines a Gamma correction factor (73) previously determined for each identified user. The gamma correction factor is determined by outputting to a Haptic Output interface a texture simulation comprising spaced grooves or ridges. By correlating user response to the perceived "feel" of the texture (rough, medium or smooth scale for example) the user's perceptual factors ca n be determined. Subsequently applying the perceptual factors to effect a mathematical adjustment (power) of texture in simulation algorithms allows output simulations to be adapted so that each user has a corresponding perception of the simulated objects.
