“Judo Health Exercise” development and planning to spread throughout Japan
J-GLOBAL ID : 200901043284363204J-GLOBAL ID : 200901004099122068J-GLOBAL ID : 202201010240591568J-GLOBAL ID : 201001039879999076J-GLOBAL ID : 200901050705583957We have developed a physical exercise named “Judo Health Exercise” base on “Judo” throwing techniques such as “Seoi-nage”, “O-goshi”, “O-soto-gari”, “Uchimata”, and “Ashi-harai”. This exercise aims at prevention of dementia and that of fall down. These throwing techniques mention above, include the motion of the body rotation and the swing leg motion. The motion of the body rotation is visually clear, but to make it certain, we have examined upper body rotation by using an accelerometer and a gyroscope. The gyroscope showed the clear body rotation. We have compared this “Judo Health Exercise” to the traditional and widely spread “Radio Exercise No.1”. By this examination. we are able to conclude “Judo Health Exercise” is developed mainly for moving the lower part of the human body. On the other hand, “Radio Exevcise No.1” was developed mainly for moving the upper part of the human body. We have also examined the emotional difference between before practicing “Judo Health Exercise” after practicing it. For this examination, We have used a questionnaire. We have depicted the motion of “Judo Health Exercise”. In the future, we are planning “Judo Health Exercise” to spread throughout Japan.1520297128944766464application/pdfdepartmental bulletin pape
A Method to Generate Freeform Curves from a Hand-drawn Sketch
When designers begin a product design, they create their ideas and expand them. This process is performed on paper, and designers' hand-drawn lines are called sketches. If the designers' hand-drawn sketches can be realized as real curves, it would be effective in shortening the design period. We have developed a method to extract five degree Bezier curves based on a hand-drawn sketch. The basic techniques to detect curves based on a hand-drawn sketch are described. First, light intensity transformation, binarization of the hand-drawn sketch, and feature based erosion and dilation to smooth the edges of the binary sketch image are described. Then, line segment determination using the detected edges is described. Using the determined line segments a five degree Bezier curve generation is described. A curve shape modification algorithm is described to reconstruct a five degree Bezier curve. Examples of five degree fair curvature Bezier curves based on a sketch are given
