PARAMETRIC MOTION CURVES AND MANIPULABLE CONTENT

摘要

Motion of manipulable content in response to input, such as touch input from a user can be defined by criteria set forth by parametric equations. An application that generates manipulable content can be tailored so that the manipulable content responds in a particular way to the input. A programmer can perform such tailoring by providing parametric equations as input to the application. A set of parametric equations can be applied to an input transform to generate an output transform, which can be used to affect motion of manipulable content as represented on an associated display, such as a touch screen display.

1. A system comprising:
an input device to receive input from a user; one or more processors communicatively coupled to the input device; memory communicatively coupled to the one or more processors; a graphics module stored in the memory and executable by the one or more processors; a display responsive to the graphics module; and a direct manipulation module stored in the memory and executable by the one or more processors to perform operations comprising:
applying a set of parametric equations to an input transform to generate an output transform; andproviding instructions to the graphics module to affect represented motion of manipulable content on the display responsive to the input received from the input device based, at least in part, on the output transform.
