Electronic device, control method, and control program

A control method executed by an electronic device including a touch panel that includes a display unit, the control method comprising:

• stereoscopically displaying a predetermined object;
• executing an operation associated with the predetermined object;
• detecting a movement of a user's physical body part in a three-dimensional space above the display unit;
• capturing images of the user's physical body part during the movement, said captured images including a smallest image of the user's physical body part at a start of the movement and a largest image of the user's physical body part when the user's physical body part is closest to the touch panel;
• determining a strength of an operation performed by the user's physical body part on the predetermined object based on a ratio between the largest image of the user's physical body part and the smallest image of the user's physical body part;
• changing a content of the operation associated with the predetermined object according to the determined strength;
• and
• based on a result of detecting a position of the user's physical body part contacting the predetermined object, adjust a degree of stereoscopic vision with which the predetermined object is stereoscopically displayed.

A non-transitory storage medium that stores a control program for causing, when executed by an electronic device including a touch panel that includes a display unit, the electronic device to execute:

• stereoscopically displaying a predetermined object;
• executing an operation associated with the predetermined object;
• detecting a movement of a user's physical body part in a three-dimensional space above the display unit;
• capturing images of the user's physical body part during the movement, said captured images including a smallest image of the user's physical body part at a start of the movement and a largest image of the user's physical body part when the user's physical body part is closest to the touch panel;
• determining a strength of an operation performed by the user's physical body part on the predetermined object based on a ratio between the largest image of the user's physical body part and the smallest image of the user's physical body part;
• changing a content of the operation associated with the predetermined object according to the determined strength;
• and
• based on a result of detecting a position of the user's physical body part contacting the predetermined object, adjust a degree of stereoscopic vision with which the predetermined object is stereoscopically displayed.
