Experiments showed small differences between leftand right-handed people that could be partially traced back to differences between their motoric skills. Differences could be observed depending on the task (identification of letters, numbers, seeing pictograms). For the lay-out of a display window, however, the differences seem to be too small to justify developing separate screen lay-outs designed for the use of left-handed or right-handed people.
