Input assisting apparatus and electronic apparatus

An electronic apparatus, comprising:

• a touch sensor panel including a plurality of first input areas assigned with input information;
• a display capable of selectively displaying a first screen including a plurality of user interface elements that correspond to the plurality of first input areas of the touch sensor panel and a second screen that is different from the first screen;
• a detector to detect that an input assisting apparatus is attached, the input assisting apparatus including
• a main body having a first surface and a second surface, the first surface facing the touch sensor panel when the input assisting apparatus is attached to the electronic apparatus, the second surface being on an opposite side of the first surface,
• one or more elastically-deformable bulge portions that respectively correspond to one or more first input areas of the plurality of first input areas of the touch sensor panel and are provided to bulge from the second surface of the main body,
• opening portions that are provided to the one or more bulge portions and expose at least a part of the one or more first input areas corresponding to the one or more bulge portions, and
• an engagement portion that is detachably attached to the electronic apparatus;
• and
• a switching section to switch display from the second screen to the first screen when the detector detects that the input assisting apparatus is attached in a case where the second screen is displayed on the display.
