Abstract

L'invention concerne un terminal portable 10A qui comprend une première unité d'acquisition 160a, une unité de détermination 160b et une unité de notification 160c. La première unité d'acquisition 160a acquiert des données d'inclinaison indiquant l'angle de tangage θ et l'angle de roulis θr qui représentent l'inclinaison du terminal portable 10A. L'unité de détermination 160b détermine, sur la base des données d'inclinaison acquises par la première unité d'acquisition 160a, si une posture voûtée d'un utilisateur utilisant le terminal mobile 10A a ou non continué pendant une période prescrite. Lorsqu'il a été déterminé par l'unité de détermination 160b qu'une posture voûtée a continué pendant la période prescrite, l'unité de notification 160c invite l'utilisateur à changer de posture en commandant la zone et la position occupées par une image d'affichage sur la surface d'affichage d'un dispositif d'affichage 120 en fonction de l'inclinaison du terminal portable 10A.
