Simulated textures whose parameters are held with object model data in a data store (5) are modified in accordance with data held in a data store (6) which 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 can 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. |
