Abstract: Perception and evaluation of distance is possible both in monocular (one eye) and binocular (using both eyes) vision.  In the latter case, the distance is estimated much more precisely. Questions of perception and distance estimates are relevant in hiring employees in different specialties, such as motor vehicle drivers, surveyors, experts in the field of engineering graphics and graphic activity. These abilities are especially important in physical education and sports, particularly in games, martial arts and orienteering. The article proposes a method for evaluation of distance perception using a camera and computer-controlled light emitters placed on a flat surface. Light emitters create two light spots on the surface. Examinee is placed in the middle of the line drawn through the centers of the light spots. Software randomly changes the area, the direction and velocity of the light spots during a predetermined time. Examinee evaluates the transformation and movement of light spots and moves to stay in the middle of the line going through the centers of the light spots. The transformation of the light spots and movements of the examinee are recorded, the video then analyzed by software that calculates the middle point, the examinee’s location and the arithmetic mean of the calculated distances. Using the arithmetic mean the examinee’s ability of distance perception and evaluation is judged. Known methods of evaluating the perception of distance uses a static position of the examinee and are less useful in the professional selection for various activities, including sport. The proposed technology is aimed at assessing the perception of distance as a result of motor actions of the examinee, which is typical for many activities.

Abstract: The article studies features of technical and tactical training in team sports using information technology. The main arguments in favor of such learning technologies are demonstrativeness, interactivity, use of combined forms of presenting the information and implementation of self-directed learning that affects the quality of learning process. These features make it possible to create such conditions of the training process by which athletes can much quicker learn the patterns of movements with complex coordination structure unavailable in conventional organization of technical and tactical training. Technology of the technical and tactical training is implemented on the playing field with controlled light light-backlit defining the light zones. Some zones, highlighted, are forbidden for the athlete; they can be static or move around simulating opponents. Such zones prevent the movement of the athlete, simulating game situations. The athlete assess the simulated situation, predicts its development, chooses a rational path and moves along it with the ball to the free zone or passes the ball through the free zone to the opponent’s area or to another member of the team. Depending on the athlete's personal level the coach chooses a program that specifies the training mode and level of complexity. The technical and tactical training level of the athlete can be judged by the number of hits into the forbidden highlighted zone, by the ability to evaluate simulated game situation and predict its development, by the ability to use own technical and tactical skills. The technology can be used in technical and tactical training of teams in varying sports, specializing in football, hockey, handball, rugby, basketball and other team sports.
