Information processing apparatus, information processing method, and computer program

A computer program for causing a computer to function as an information processing apparatus which includes

• a detection control section configured to cause a detection section to detect contact of an operating object with and proximity of the operating object to a display surface of a display section on which objects classified into groups in accordance with a relationship between the objects are displayed,
• a proximity determination section configured to determine a degree of proximity of the operating object to the display surface based on a detection result obtained by the detection section, and
• an operation-lock determination section configured, when the proximity determination section determines that the operating object touches the display surface, to disable an operation input to an object belonging to a group different from a group which an object that the operating object touches belongs to, until the operating object is positioned outside a proximity detection region, the proximity detection region being a region from the display surface to positions which are a predetermined distance away therefrom.
