Indeterminable gesture recognition using accumulated probability factors

摘要

The present invention is to appropriately determine a gesture operation detected to perform data processing according thereto. In the present invention, a CPU judges a processing status at the time of the detection of a gesture operation performed on a touch panel, and after determining its gesture operation type according to the processing status, performs data processing according to the operation type. In this case, the CPU determines and evaluates a gesture operation type for each processing status, and updates values (evaluation accumulation values) of a flick priority pointer and a tap priority pointer. Then, based on these values of the flick priority pointer and the tap priority pointer, the CPU determines one of the gesture operation types (flick operation/tap operation).

主权项

1. A data processing device including a detection section which detects a plurality of gesture operations including gesture operations of types of flick operations or gesture operations of types of tap operations, comprising:
a judging section which, when a new gesture operation by the detection section is detected, judges whether the detection is detection after a first time is elapsed since predetermined data is displayed on the data processing device, or is detection after a second time is elapsed since a previous gesture operation is detected in the data processing device, or is detection after a third time is elapsed since a display size of an image displayed on the data processing device is changed; an updating section which updates any of a first pointer in which the types of flick operations are prioritized and a second pointer in which the types of tap operations are prioritized according to a result of one type of judgment of the judging section, and, when plural types of judgments are detected in the judging section, updates by respectively accumulating the first pointer and the second pointer for each of the plural types of judgments; a data processing section which performs a comparison of the first pointer and the second pointer accumulated and updated in the updating section and determines whether the types of flick operations or the types of tap operations are used as a type of the gesture operation based on a result of the comparison; a reading section to read an attribute of the image displayed on the data processing device from an image memory and, according to the attribute, judging whether the image is a printed image, a non-extended image, or an extension error image; and if the image is a printed image, a non-extended image, or an extension error image, determining that the image has a low possibility of being selected.
