1. An information processing apparatus comprising:
a touch operating unit, wherein the touch operating unit is configured to be touch operated by two or more operators; a detecting unit, wherein the detection unit is configured to detect whether the two or more operators are in touch with the touch operating unit; a mode selecting unit, wherein the mode selecting unit is configured to select between a blind mode or a normal mode based on the touch state detected by the detecting unit, wherein:
the normal mode is configured to both receive user input from the two or more operators and provide visual feedback through a display screen of the touch operating unit; andthe blind mode is configured to receive user input from the two or more operators without any visual feedback from the display screen of the touch operating unit; a coordinate system determining unit, wherein the coordinate system determining unit is configured to determine in the blind mode an independent coordinate system different from a default coordinate system of the touch operating unit, wherein the independent coordinate system in the blind mode is according to a dragging direction of the two or more operators on the touch operating unit; a relative position calculating unit, wherein the relative position calculating unit is configured to calculate a relative position of each of the two or more operators on the independent coordinate system in the blind mode; and a command issuing unit, wherein the command issuing unit is configured to issue a predetermined operation command based on the relative position of the touch state and movement of each of the two or more operators on the independent coordinate system, wherein the touch operating unit, the detecting unit, the mode selecting unit, the coordinate system determining unit, the relative position calculating unit, and the command issuing unit are each implemented via at least one processor. |
