Input apparatus and information processing apparatus

An information processing apparatus, comprising:

• a keyboard module comprising:
• a plurality of key areas;
• and
• a plurality of sensor devices,
• wherein each sensor device of the plurality of sensor devices is configured to detect pressure of a keystroke operation of a respective key area of the plurality of key areas;
• a control circuit configured to:
• detect the keystroke operation at a position between a first key area of the plurality of key areas and a second key area of the plurality of key areas;
• detect a first pressure at the first key area based on the keystroke operation at the position between the first key area and the second key area;
• detect a second pressure at the second key area based on the keystroke operation at the position between the first key area and the second key area, wherein the first pressure and the second pressure are detected at a same time;
• and
• generate a difference between an input sensitivity of the keystroke operation of the first key area and an input sensitivity of the keystroke operation of the second key area, wherein
• the second key area is adjacent to the first key area, and
• the difference is generated based on the first pressure detected at the first key area and the second pressure detected at the second key area;
• and
• a display unit configured to display an image corresponding to the keystroke operation based on an output from the control circuit.
