The sum of the measurement results of the weighing scales A to D (A
Since + B + C + D) is equal to the weight of the person H, if the weights of many participants are known, it is possible to identify that person from the measurement results.

In the above embodiment, the plate 9
Although four weight scales A to D are arranged for one, if at least three weight scales are arranged in a plane rather than linearly, the position on the plate 91 can be calculated. You can

Further, for example, the plate 9 of the person H is taken every one second.
By obtaining the position on 1, the moving direction and speed of the person H can be obtained. Furthermore, by monitoring the sum (A + B + C + D) of the measurement results of the weight scales A to D, the timing when the person H jumps and the timing when the person H lands can be detected. That is, when jumping, the sum of the measurement results of the weighing scales A to D suddenly decreases. Conversely, at the moment of landing, the sum suddenly increases. From this change in value, the jump timing and the landing timing can be detected.

Further, as shown in FIG. 6, when the weights a to d are arranged so that the change in the horizontal load of the plate 91 can be detected, when the person H rotates on the plate 91. , It is possible to detect this. That is, when the person H rotates, he kicks his foot in that direction, so that the measurement result in that direction among the weighing scales a to d becomes large. Therefore, the rotation can be detected from the change in the value.

FIG. 7 shows still another embodiment.
That is, in this embodiment, the plate 91 has the region R ₁
To R ₉ are divided into nine regions, and four weighing scales A _{i to} D _i are arranged in each region R _i . Thus, if the plate 91 is divided into a plurality of regions, the position of the person H can be detected more accurately.

[0041]

As described above, according to the position detecting device of the present invention, the position of the weight point on the plate is calculated from the measurement result of the weight scale arranged so as to measure the weight applied to the plate. Therefore, the position of the mass point on the plate can be accurately detected with a simple configuration.

Further, according to the game device of the present invention, the position on the plate is calculated according to the measurement result of the weighing scale, and the image on the spectacles type display is changed according to the calculation result. Therefore, it is not necessary to provide a sensor for position detection on the spectacles type display, and the spectacles type display can be reduced in weight and size. Therefore, even if the spectacles type display is worn on the head for a long time, the risk of getting tired is reduced and the operability can be further improved.
