An input apparatus that accurately determines an input operation intended by a user without erroneously determining an operation including no move as an operation including move. Touch positions in a time period from touch-down to touch-up by an input operation performed on a touch panel by the user are recorded in chronological order. A statistical variance of the touch positions is calculated based on the obtained touch positions. Whether the input operation is an operation including no move or an operation including move is determined based on the calculated variance. When the calculated variance is smaller than a threshold value, it is determined that the input operation is the operation including no move, and when the calculated variance is not smaller than the threshold value, it is determined that the input operation is the operation including move.

FIG. 1 is a block diagram schematically showing an arrangement of an essential part of an information processing apparatus in which an input apparatus according to a first embodiment of the present invention is incorporated.
FIG. 2A is a view showing an exemplary user interface screen. FIG. 2B is a view showing a dragging operation performed on the user interface screen in FIG. 2A. FIG. 2C is a view showing a tapping operation performed on the user interface screen in FIG. 2A.
FIG. 3 is a flowchart of the procedure of an input operation determination process according to the first embodiment.
The present invention will now be described in detail with reference to the drawings showing embodiments thereof.
FIG. 1 is a block diagram schematically showing an arrangement of an essential part of an information processing apparatus in which an input apparatus according to a first embodiment of the present invention is incorporated. In the following description, it is assumed that on the input apparatus, an operation including no move (a tapping operation) or an operation including move (a dragging operation or a flicking operation) is performed as an input operation by a user.
Referring to FIG. 1, the input apparatus according to the present embodiment is incorporated in an information processing apparatus 100 such as a PC (personal computer). The information processing apparatus 100 has a CPU 101, a program storage unit 102, a memory 103, a touch panel 104, and a display control unit 105, which can exchange data with each other via an internal bus 111.
