Posture guidance program, posture guidance method, and information processing device.

Abstract

The present invention acquires posture information relating to each of a hand and a smartphone, and calculates an easiness of movement from a current posture as the mobility. In positioning for performing hand biometric authentication using a smartphone, a determination as to which of the hand or the smartphone is appropriate to be moved is performed on the basis of the mobility. The efficiency of the positioning is improved by giving a posture guidance through displaying, on the basis of a result of said determination, the way of moving either one of the hand or the smartphone which has a higher mobility.

In calculating the mobility of the terminal, the range of motion of the terminal, which is associated with the acquired orientation information of the terminal, is obtained as the calculation result of the terminal's mobility from a terminal model in which the orientation information of the terminal and the range of motion of the terminal are associated. In the output of the guidance information, the guidance information is output for the one of the subject and the terminal that has a wider range of motion. The posture guidance program according to claim 1.

3. In calculating the mobility of the subject, The range of motion of the subject, which is associated with the acquired posture information of the subject, is acquired as the range of motion of the subject model from the subject model, which is associated with the posture information of the subject and the range of motion of the subject. The range of change in the posture information of the subject when the posture information of the subject is acquired multiple times is acquired as the range of motion of the subject. The ratio of the movable range of the subject model to the movable range of the subject is calculated to obtain the result of calculating the mobility of the subject. In calculating the mobility of the aforementioned terminal, The range of motion of the terminal, which is associated with the attitude information of the terminal that was acquired, is acquired as the range of motion of the terminal model from the terminal model, which is associated with the attitude information of the terminal and the range of motion of the terminal. The range of change in the posture information of the terminal when the posture information of the terminal is acquired multiple times is acquired as the range of motion of the terminal. The ratio of the movable range of the terminal model to the movable range of the terminal is calculated to obtain the result of calculating the mobility of the terminal. In the output of the guidance information, the guidance information is output for the one with the larger ratio of the movable range between the subject and the terminal. The posture guidance program according to claim 1.

4. The subject in question is either the right or left hand. The terminal is held in the hand opposite to the one mentioned above. In calculating the mobility of the subject, The value of one end of the range of motion of the subject, which is associated with the acquired posture information of the subject, is obtained from the subject model, which is associated with the posture information of the subject and the range of motion of the subject, as the value of the end of the range of motion for the subject model. When the posture information of the subject is acquired multiple times, a representative value of said posture information is obtained, and the value at one end of said posture information is obtained as the value at the end of the movable range for the subject. The ratio of the absolute value of the difference between the value at the end of the movable range for the subject model and the representative value for the subject to the absolute value of the difference between the value at the end of the movable range for the subject and the representative value for the subject is calculated to obtain the result of calculating the mobility of the subject. In calculating the mobility of the aforementioned terminal, The value of the other end of the movable range of the terminal, which is associated with the attitude information of the terminal, is obtained from the terminal model, which associates the attitude information of the terminal with the movable range of the terminal, as the value of the end of the movable range for the terminal model. When the attitude information of the terminal is acquired multiple times, a representative value of said attitude information is obtained, and the value at the other end of said attitude information is obtained as the value at the end of the movable range for the terminal. The ratio of the absolute value of the difference between the value at the end of the movable range for the terminal model and the representative value for the terminal to the absolute value of the difference between the value at the end of the movable range for the terminal and the representative value for the terminal is calculated to obtain the result of calculating the mobility of the terminal. In the output of the guidance information, the guidance information is output for the one with the larger ratio value calculated as a result of the mobility calculation between the subject and the terminal. The posture guidance program according to claim 1.

5. The attitude information of the terminal is acquired using a gravity sensor, an acceleration sensor, or a geomagnetic sensor provided in the terminal, according to any one of claims 1 to 4.

6. The posture guidance program according to claim 5, wherein the posture information of the subject is acquired using an image capture device or LiDAR provided in the terminal.

7. The posture guidance program according to any one of claims 1 to 4, wherein the guidance information is displayed on the screen as characters or symbols.

8. The posture guidance program according to claim 7, wherein the screen display of the guidance information for the subject and the screen display of the guidance information for the terminal are of different colors.

9. The posture guidance program according to any one of claims 1 to 4, wherein the guidance information is voice information.

10. From the image of the subject, which is a living organism, biological information is extracted. By comparing the extracted biometric information with a pre-registered biometric information template, a biometric authentication process is performed to confirm whether the biometric information belongs to a pre-registered person to be authenticated. The attitude guidance program according to any one of claims 1 to 4, wherein the information processing device performs further processing.

11. The posture guidance program according to claim 10, further comprising causing the information processing device to perform a process of registering the extracted biological information into the template.
