Method for performing an interactive game Each user is provided with means for identification as game participant, provided with a mark. As a mark, optical signal source is used. Positioning of device for receiving optical signals is performed relatively to multiple users. Source position of identification means of game participant is held relatively to means for receiving optical signals in accordance to game conditions. Game objects and rules are given to participants and game start signal is given. User targets his mark to appropriate means for receiving optical signals. Optical signals are received from game participants and received optical signals are registered in registration device.

Method for automatic processing of voting papers and device for realization of said method Method includes inserting vote papers into track and moving them along track while synchronously reading their full width images on both sides of sheet with recognition of voter marks and qualification of papers with concurrent marking of invalid papers, read image if transformed to digital code signals, appropriate for semi-tone presentation of image and also lighting level is automatically set, determined by white field of paper and corrections are introduced compensating unevenness of transfer of signals by objective and distortions, caused by blinks from parts of optical track and deviation of sensitivity of elements of reading photo-receiver, on basis of multiplication of signals of image of each element of read string of vote paper on coefficients, determined for each read element during scanning of white field. |
