The thesis analyzes human interaction with various virtual objects, using the system of power reversible connection. Such types of systems are becoming more and more frequent while giving virtual graphic information to the blind. Owing to the system of power reversible connection and the system of human touching blind people can now receive both virtual written and virtual graphic information. Since touching is one of the most important human sensory systems with the help of which a person receives the majority of information about his/her surroundings (i.e. identifies the pattern of the surface, resistance to the pressure, its temperature, weight, form and contour of the object), it is very important to use this system to make the life of the blind easier. The aim of the research was to carry out the identification of the virtual figures, using the device of power reversible connection “Phantom omni” and the program based on “Microsoft Visual C++”. 5 blindfolded people with no sight problems participated in the research. They were given 6 two – dimensional and three – dimensional figures. Having analyzed the data, it was concluded that men perform twice quicker than women. Men adapt to the changes in space faster as well. Having divided the people according to their sex, statistical results were received investigating the figures separately. It was revealed that the optimum size of the figure is about 26 – 39 mm. The most convenient is a two – dimensional work space with the fixed primary cursor point when dealing with the circle. The figure which is in the centre of the investigated space is usually found the most easily. |
