  Next, the bending characteristic or the twist characteristic of the ski or snowboard suitable for the weight, leg strength or the skiing skill level of each skier or snowboarder input in the step S2 is determined (step S3). ). Thereafter, the ski or snowboard corresponding to the bending characteristic or torsion characteristic determined in step S3 is determined (step S4).

  Next, the ski or snowboard determined in step S4 is read from the storage means 8 and notified in step S6.

  FIG. 16 shows a simulation when the user skies using the selected ski or snowboard based on the weight / leg strength of the skier or snowboarder or the skiing technique as described above. To display this simulation, it is necessary to determine the turn arc radius R based on the length of the selected ski or snowboard, the side curve, and the like.

  Next, a method for obtaining the turn arc radius of the selected ski or snowboard will be described with reference to FIGS. 9, 10, 17, and 18. FIG.

  First, as shown in FIG. 9, the X axis is set in the longitudinal direction of the ski and the Y axis is set in the width direction. The tail width of the ski (the widest part of the rear half), the waist width (the narrow part of the central part), and the shoulder width (the wide part of the front half) are designated as Bh, Bw, and Bs, respectively. The lengths from the rear end of these skis are Lh, Lw, and Ls, respectively. If the tail, waist, and shoulder points on the side curve are A, B, and C, respectively, the coordinates are A (Lh, Bh / 2) B (Lw, Bw / 2), C (Ls, Bs) / 2). In addition, the intersection of the straight line AC and the straight line drawn vertically from the point B to the straight line AC is D, and the distance between the BDs is Sc. Further, the length of the CE of the right triangle ACE having the straight line AC as the hypotenuse is Z, and ∠CAE is α.

When the ski is edged (squared), it is assumed that the ski rotates about the straight line AC (see FIG. 16, where the edging angle is θ). Assume that it is pressed upward (XY plane). That is, the point B is projected onto B ′. The arc AB′C thus created is assumed to be a turn arc, and the radius of curvature of the arc passing through the point AB′C is assumed to be the turn arc radius R when edged (however, the positions of the points A and B) Assume that does not move.)
In the above setting, the turn arc radius R is obtained by the following procedure. First, as shown in FIG. 18, consider a coordinate form having a point A as the origin and a straight line AC as the X axis. If the coordinates of the points A, B ′ and C are (X1, Y1), (X2, Y2) (X3, Y3), respectively, the general formula of a circle passing through the three points is given by Equation 7.

又、３点Ａ,Ｂ´,Ｃを通る円弧の中心座標（Ｓ,ｔ）は数８によって求まる。

Further, the center coordinates (S, t) of the arc passing through the three points A, B ′, C are obtained by the following equation (8).

又、前記円弧の半径Ｒは数９で求められる。

Further, the radius R of the arc is obtained by the following equation (9).

又、スキーヤーがＸ方向へ距離１００ｍ滑走したときのターン回数をＴとすると、
Ｔ＝１００／２Ｒによって求めることができる。

Also, if the number of turns when the skier slides 100m in the X direction is T,
It can be obtained by T = 100 / 2R.

  When displaying the turn trajectory, an XY coordinate system is used as shown in FIG. The ski turn that continues from the left turn to the right turn can be expressed by the following general formula from the edging angle, the width of the three main points of the ski, and the turn arc radius R calculated from the positions. When the numerical value K that determines the direction of the turn is odd, it means a left turn, and when it is an even number, it means a right turn.

そして、図１９に示すように、前述のＸ,Ｙを点で表示することにより、滑走の状態の静止画を表示することができる。

Then, as shown in FIG. 19, a still image in a sliding state can be displayed by displaying the aforementioned X and Y as dots.

  In addition, as shown in FIG. 6, according to the preference of a skier or a snowboarder, you may make it input different of large rotation, middle rotation, and small rotation. The large turn, middle turn, and small turn are added between step S2 and step S3 in the flowchart shown in FIG. As described above, when the skis or snowboards determined to be suitable for each skier or snowboarder are suitable for the large, medium or small turns selected according to the preference of each skier or snowboarder. May display that fact, and if not, it may display that fact. That is, FIG. 21 shows that the turn arc radius of skis or snowboards determined to be suitable for each skier or snowboarder is included in the range of small turns and is suitable for small turns as shown by the dots in FIG. Is displayed. On the other hand, FIG. 22 displays in black the upper limit of the small turning range that the turn arc radius of the ski or snowboard determined to be suitable for each skier or snowboarder is not included in the small turning range. Is displayed to indicate that it is outside the upper limit.

  In the above embodiment, as shown in FIG. 1, the PC 32 for obtaining the weight, leg strength and maximum load of the skier or snowboarder and the PC 3 constituting the board characteristic determining means 9 and the board searching means 10 are separately provided. Although provided, a single PC may serve as the two PCs.

  In the above embodiment, the ski or snowboard suitable for the skier or snowboarder's weight, leg strength, and level of skiing skill is determined, but the skier or snowboarder's preferred skiing method, height, degree of obesity, A ski or snowboard suitable for each skier or snowboarder may be determined in consideration of age.

  Furthermore, if a mounting portion for mounting ski shoes or snowboard shoes is provided on the foot plates 34 and 35 and the person to be measured measures the load while wearing the ski shoes or snowboard shoes, It is possible to measure the leg strength and the like under actual conditions. Further, the person to be measured may wear ski shoes or snowboard shoes, and may further measure the load on the foot plates 34 and 35 with the ski or snowboard worn.

  The foot plates 34 and 35 may be provided horizontally, but the foot plates 34 and 35 are tilted in the front-rear direction, or are tilted left and right around the axis L1 and L2 of the foot plates 34 and 35. If the person to be measured is placed on the foot plates 34 and 35 so as to be in a so-called toe-up state, a toe-down state, or a twisted state to the left and right, The leg force and center of gravity distribution of the person being measured can be measured while actually performing snowboarding.
