Popularne obecnie interfejsy dotykowe, pozwalające w prosty sposób sterować maszynami, powstały ponad dwadzieścia lat temu. Obraz wyświetlany był początkowo na ekranach CRT z dołożoną matrycą dotykową. Później pojawiły się ekrany LCD podświetlane awaryjnymi lampami katodowymi. Dzisiaj standardem jest już podświetlenie LED, które jest właściwie niezawodne. Ewolucja interfejsów sterowniczych rozpoczęła się od przeniesienia przycisków mechanicznych z szafy sterowniczej na ekran monitora w formie graficznego odwzorowania.

Sight is the most important sense of a human. For the most of the society, the perception performed by the sight organ is perceived as something very natural. Reflection on life without the sight is not common, which slows down the technological development aiming at reducing the social exclusion of persons with sight disabilities. The dynamical development of advanced technologies does not provide solutions for all the cases of illness. However, many tools exist which allow people with visual disabilities to interact with the outside world. In most cases these tools allow only for the exchange of very basic information. We present some problems associated with the visualization of images for the blind, with the attention concentrated upon business graphics. We also give some propositions to enhance the level of non-visual perception of images with the use of specialized tactile equipment.

In the treatment of craniofacial osseous defects it is frequently required that the surgeon has to graft bone to replace a missing or surgically removed segment. The reconstruction of this area poses a difficult challenge owing to the complexity of its bony structures as well as to its great importance for the chewing and speech ability. A common method of surgically reconstructing the craniofacial region involves using autologous grafts. By using the registration framework a novel surgery planning method has been developed. The method enables computer-aided selection of optimal donor sites for autologous bone grafts in the craniofacial surgery. The main advantage of the method is that after determination of the initial conditions and constraints it provides an automatic procedure to find the best fitting position. All generated solutions can be explored interactively on the computer display via an efficient graphical interface. Applying different similarity measures enables the surgeon to select the optimal donor site not only in terms of bone surface correlation but also according to the whole volumetric information contained in both data sets. This new approach permits more precise planning of the surgical procedure, reducing intraoperative time and improving the postoperative outcome.
