摘要： Systems and methods are provided that determine when an initial stroke and a subsequent stroke track may be part of a common user input action. A method may include receiving a signal from which an initial stroke track representing an initial movement of a user controlled indicator against a touch sensitive surface and sensing a subsequent stroke track representing subsequent movement of the user controlled indicator against the touch sensitive surface can be determined. The method further includes determining that the initial stroke track and the subsequent stroke track comprise portions of common user input action when the initial stroke track is followed by the subsequent stroke track within a predetermined period of time and a trajectory of the initial stroke track is consistent with a trajectory of the subsequent stroke track.

摘要： An electronic device includes a touch-sensitive surface, for example a touch pad or touch screen. The user interacts with the touch-sensitive surface, producing touch interactions. The resulting actions taken depend at least in part on the touch type. For example, the same touch interactions performed by three different touch types of a finger pad, a finger nail and a knuckle, may result in the execution of different actions.

摘要： Methods and apparatuses are provided for determining a pitch and yaw of an elongated interface object relative to a proximity sensitive surface. In one aspect, a proximity image is received having proximity image data from which it can be determined which areas of the proximity sensitive surface sensed the elongated interface object during a period of time. A proximity blob is identified in the proximity image and the proximity image is transformed using a plurality of different transformations to obtain a plurality of differently transformed proximity images. A plurality of features is determined for the identified blob in the transformed proximity images and the pitch of the elongated interface object relative to the proximity sensitive surface is determined based upon the determined features and a multi-dimensional heuristic regression model of the proximity sensitive surface; and a yaw is determined based upon the pitch.
