Visual sense power display and visual sense power science teaching aid and scientific toy

摘要

P To provide a visual dynamic display device as a science text and capable of visually recognizing both of the magnitude and direction of dynamics. PSOLUTION: The visual dynamic display device 10 includes: a three-axis acceleration sensor 20A; a filter amplifier circuit 30 for applying noise elimination processing to acceleration information in three-axis direction detected by the acceleration sensor 20A; a controller 40 for generating display information based ON acceleration information; and a display 50 having an x-, y- and z-axis display unit displaying the direction and magnitude of dynamics working in three-axis direction based ON the display information. The filter amplifier circuit 30 reduces a cut-off frequency fz applied to the z-axis acceleration information to be smaller than a cut-off frequency fx and fy (fx=fy) applied to the x-axis and y-axis acceleration information. Further, by permitting the visual dynamic display unit 10 to tilt only around y-axis and gravitation is broken down into x-axis and z-axis components to be displayed.
