Force plate and information processing system
A technique to facilitate continuing the operation through a load applied by a user who proceeds with a picture program is provided. A force plate functions as a controller controlling a game console. The foot pressure includes a transmitting section configured to transmit, when the COP of a user enters a peripheral part of the force plate, an alert signal to an HM display configured to output a picture from the game console.
1 . A force plate that functions as a controller controlling a picture generating device, the force plate comprising:
a top board;
a six-axis force sensor configured to detect forces in three axial directions and moments about three axes that act on the top board, wherein the six-axis force sensor is configured to detect a center of foot pressure of a user, a floor reaction force, and a free moment;
a first processor; and
a transmitting section configured to transmit, when the first processor determines, based on a detection value of the six-axis force sensor, that the center of foot pressure of the user has entered a peripheral part of the force plate, an alert signal to the picture generating device or to a display that outputs a picture generated by the picture generating device, wherein
the first processor obtains, based on the detection value from the six-axis force sensor, information on a posture of the user and information on a motion of the user.
2 . The force plate according to claim 1 , wherein the display is a head-mounted display.
3 . The force plate according to claim 1 , wherein the transmitting section is configured to transmit to the picture generating device or to the display a signal, as the alert signal, instructing that an alert sound be emitted.
4 . The force plate according to claim 1 , wherein the transmitting section is configured to transmit to the picture generating device or to the display a signal, as the alert signal, instructing that an image which covers up at least a part of the picture be displayed on the display.
5 . The force plate according to claim 1 , wherein the force plate includes a bump in the peripheral part.
6 . An information processing system comprising:
the force plate according to claim 1 , the force plate including: a top board; a six-axis force sensor configured to detect forces in three axial directions and moments about three axes that act on the top board; and a first processor; and
a display configured to display an image responsive to a signal from the force plate, wherein
the six-axis force sensor is configured to detect the center of foot pressure of a user, a floor reaction force, and a free moment, and
when the first processor determines, based on a detection value of the six-axis force sensor, that the center of foot pressure of the user has entered a peripheral part of the force plate, an alert signal is transmitted to the picture generating device or to a display that outputs a picture generated by the picture generating device, wherein
the first processor obtains, based on the detection value from the six-axis force sensor, information on a posture of the user and information on a motion of the user.
7 . The information processing system according to claim 6 , wherein
the display is a head-mounted display.
8 . The information processing system according to claim 6 , wherein
the transmitting section is configured to transmit to the picture generating device or to the display a signal, as the alert signal, instructing that an alert sound be emitted.
9 . The information processing system according to claim 6 , wherein
the transmitting section is configured to transmit to the picture generating device or to the display a signal, as the alert signal, instructing that an image which covers up at least a part of the picture be displayed on the display.
10 . The information processing system according to claim 6 , wherein
the force plate includes a bump in the peripheral part.
11 . The information processing system according to claim 7 wherein
the head-mounted display includes: a gyro sensor or an acceleration sensor; and a second processor, and
the second processor obtains, based on a detection value from the gyro sensor or the acceleration sensor, information on a position and an orientation of a head of the user.
12 . The information processing system according to claim 6 , further comprising
a controller, which is a device capable of being operated by a user with the user holding the controller in their hand(s), wherein
the controller includes: a gyro sensor or an acceleration sensor; and a third processor, and
the third processor obtains, based on a detection value from the gyro sensor or the acceleration sensor, information on a position and an orientation of the hand(s) of the user.
