FIELD: information technologies. ^ SUBSTANCE: case is made in the form of truncated cone and has through hole for writing device. The hole is located coaxially with cone centre line. Guiding elements for thumb, forefinger and middle finger form triangle in cross section. Thickening in the form of comb located between guiding elements for thumb and forefinger is corner of the triangle. The comb is provided with profiled marker in the form of sphere for correct device orientation on writing tool, and is positioned at right angle to through hole. Guiding elements for thumb, forefinger and middle finger are positioned relative to marker at angles of 70-80, 45-55 and 55-65 respectively. Guiding elements for fingers are made in the form of indents with radius for thumb of 19-25 mm at distance from centre line of 25-26 mm, for forefinger - with radius of 16-20 mm at distance from centre line of 22-23 mm and for middle finger -with radius of 16-20 mm at distance from centre line of 24-25 mm. ^ EFFECT: training simulator efficiency improvement. ^ 5 dwg |
