Information processing apparatus, method of processing information, and recording medium

A method of processing information used for an information processing apparatus including an operation display device including a touch panel;

• a hardware key input device configured to be placed on the operation display device, the hardware key input device including a key top having a high dielectric constant for pressing the touch panel;
• and a placement detector configured to detect placement of the hardware key input device on the touch panel, the method comprising:
• detecting the placement of the hardware key input device using the placement detector;
• and
• causing a display on the touch panel to transition to a mode enabling a pressing operation using the hardware key input device when the placement detector detects the placement of the hardware key input device.

A non-transitory recording medium storing computer readable code for causing an information processing apparatus to execute a method of processing information, the information processing apparatus including an operation display device including a touch panel;

• a hardware key input device configured to be placed on the operation display device, the hardware key input device including a key top having a high dielectric constant for pressing the touch panel;
• and a placement detector configured to detect placement of the hardware key input device on the touch panel, the method comprising:
• detecting the placement of the hardware key input device using the placement detector;
• and
• causing a display on the touch panel to transition to a mode enabling a pressing operation using the hardware key input device.
