Gesture-based input information processing apparatus |
摘要 |
An information processing apparatus obtains a distance that an input pen is moved in terms of the number of dots covered on a display screen, and from that number, judges whether a pen stroke is a gesture entry or a pointing entry. When the input pen is moved over more than a predetermined number of dots, e.g., eight dots, gesture recognition processing is performed. If the input pen is moved less than that number of dots, a pointing instruction is recognized, and pointing processing is performed. If a gesture is recognized, a recognized gesture editing command and a feature point of the gesture command are stored in RAM. Since an input by the input pen is judged a gesture entry or a pointing entry according to the number of dots over which the input pen is moved, a switch is not required to change data/instruction entry modes which reduces cost and improves handling.
