Abstract: A set of rules is used by a processor of a device to render a digital image of handwriting (e.g., handwritten signature) by connecting data points captured on a touch sensitive surface of the device with line segments or curves. A set of rules determines whether two given data points will be connected by a line segment or a curve. If a curve is used, the set of rules determine characteristics of the curve through the derivation of control points. In some implementations, a smoothness adjustment factor can be applied to magnitudes of curve control points to reduce excessive smoothing for large distances between data points and maintain acceptable smoothing for short distances between data points. The magnitude can then be adjusted by multiplying by a constant factor which can be determined (e.g., heuristically) from the processing speed and resolution of the device upon which the curve is being rendered.

Abstract: One or more regions of a touch sensitive surface can be activated individually by a user. A region defines an active input area for processing touch input events. Any touch event associated with a beginning touch event that is detected in the active area is processed for display. Any touch input event detected outside the active region that is not associated with the beginning touch event is excluded from the processing. Once a writing gesture is started in the active region, the writing gesture can extend outside of the active region so long as the writing gesture is associated with the beginning touch event.

Abstract: Methods, program products, and systems implementing remote container techniques are disclosed. A relational database can include a container data field, which can be a data field for storing multimedia data. In one aspect, when the multimedia data are inserted into the container field, the multimedia data can be stored in one or more remote database files. The remote database files can be located separately from other data of the relational database and remotely from a client computer accessing the relational database. Corresponding data structures, or remote containers, can be configured to store metadata of the database files. References to the remote containers can be stored as values of the container data field. Using various encryption techniques, the remote database files can be given same access restrictions as access restrictions of the container data field, even when the remote database files are stored as flat files.
