Wearable terminal and display control method

A display control method performed by a wearable terminal, the wearable terminal including

• a display that displays information in an active state and that does not display the information in a sleep state,
• a detector that detects a direction of a display surface of the display at different times, and
• a processor,
• the display control method causes the processor to perform:
• a first determination that determines whether the detected direction by the detector at a latest time is within a first angle range defined by a rotation angle of the display surface from a first reference direction about a rotation axis defined by each of at least two axes in a 3-dimensional space;
• and
• a first display control (i) that puts the display in the sleep state in a case where a result of the first determination indicates that the detected direction by the detector at the latest time is out of the first angle range and (ii) that puts the display in the active state in a case where the result of the first determination indicates that the detected direction by the detector at the latest time is within the first angle range;
• the display control method further causes the processor to perform:
• a specification that specifies a second angle range which is defined by a rotation angle of the display surface from a second reference direction about a rotation axis defined by each of at least two axes in the 3-dimensional space and which is out of the first angle range, wherein the second reference direction is defined in a direction identified using at least one of directions of the display surface detected at the different times;
• a second determination that determines whether the plurality of directions of the display surface detected in a first period with a first predetermined length till a present time remain in the determined second angle range;
• a third determination that determines whether a direction of the display surface newly detected by the detector is out of the second angle range in a case where a result of the second determination indicates that the plurality of directions of the display surface detected in the first period remain in the second angle range;
• and
• a second display control that switches the display from the sleep state to the active state in a case where a result of the third determination indicates that the direction of the display surface newly detected by the detector is out of the second angle range,
• wherein, in the second display control, the display is switched from the sleep state to the active state even when the newly detected direction of the display surface is out of the first angle range.
