Electronic apparatus, display control method, and program

An electronic apparatus comprising:

• an input/output unit that displays a plurality of operation markers, which are used for performing an operation input, on a display surface and detects an object that is in proximity to or brought into contact with the display surface;
• a selection unit that sets selection targets selected through detection of the object to a plurality of operation markers in a case where the detection state of the object on the display surface exceeds a predetermined reference, sets a selection target selected through detection of the object to one operation marker in a case where the detection state does not exceed the predetermined reference, and selects one or more operation markers from among the plurality of operation markers displayed on the display surface based on the detection state;
• and
• a display control unit that changes the display forms of the operation markers selected from among the plurality of operation markers displayed on the display surface into a display form indicating a selected state and displays the selected operation markers on the display surface.

A display control method comprising the steps of:

• detecting an object that is in proximity to or brought into contact with a display surface on which a plurality of operation markers, which are used for performing an operation input, is displayed;
• determining, based on a detection state of the object on the display surface, either a multiple selection mode in which selection targets selected through detection of the object are set to be a plurality of the operation markers or a single selection mode in which the selection target selected through detection of the object is set to be one operation marker, as a selection mode;
• selecting one or a plurality of operation markers from among the plurality of operation markers displayed on the display surface based on the determined selection mode and the detection state;
• and
• changing display forms of the operation markers that are selected from among the plurality of operation markers displayed on the display surface into a display form indicating a selected state and displaying the selected operation markers on the display surface.

A computer program that allows a computer to perform the steps of:

• detecting an object that is in proximity to or brought into contact with a display surface on which a plurality of operation markers, which are used for performing an operation input, is displayed;
• determining, based on a detection state of the object on the display surface, either a multiple selection mode in which selection targets selected through detection of the object are set to be a plurality of the operation markers or a single selection mode in which the selection target selected through detection of the object is set to be one operation marker, as a selection mode;
• selecting one or a plurality of operation markers from among the plurality of operation markers displayed on the display surface based on the determined selection mode and the detection state;
• and
• changing display forms of the operation markers that are selected from among the plurality of operation markers displayed on the display surface into a display form indicating a selected state and displaying the selected operation markers on the display surface.
