A touch gesture can be detected on a touch screen. One or more direction changes associated with the touch gesture can be detected and the angle of each of the direction changes can be determined to meet a predetermined threshold. The touch gesture can be detected as no longer touching the touch screen and a polygon can be generated based on each of the direction changes associated with the touch gesture."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pencil eraser gesture and gesture recognition method for touch-enabled user interfaces","description":"Methods and systems for receiving an erasure gesture input and accordingly deleting content in a viewable area of a multi-touch input display device are disclosed.
