Title:
DRAWING DEVICE, DRAWING METHOD AND DRAWING PROGRAM
Document Type and Number:
Japanese Patent JP2014182814
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily and swiftly draw desired shapes.SOLUTION: A system and method are provided for generating geometric shapes on a display screen using multiple stages of gesture recognition. The method relies upon a display screen having a touch sensitive interface to accept a first touch input. The method establishes a base position on the display screen in response to recognizing the first touch input being recognized as a first gesture. The touch sensitive interface then accepts a second touch input having a starting point at the base position, and an end point. A geometric shape is interpreted in response to the second touch input being recognized as a second gesture, and the method presents an image of the interpreted geometric shape on the display screen. A human finger, a marking device, or both may be used for the touch inputs.
