PROBLEM TO BE SOLVED: To provide a posture detection method which can achieve a technique for detecting the posture of a user and a distance between a screen and eyes of the user from a portable terminal, a portable terminal device, and a program.SOLUTION: By using inclination of a terminal calculated by terminal angle calculation means 2 on the basis of acceleration acquired from an acceleration sensor 1, posture determination means 3 determines goodness of the posture of a user by comparing inclination information stored in a posture information DB 4 and the inclination of the terminal. Then, information presentation means 5 presents the goodness of the posture to the user on the basis of the determination result. |
