Abstract
Methods and devices provide an efficient user interface for providing continuous zoom or magnification of a displayed image on a computing device. A user may initiate a zoom-in or zoom-out function by tracing an ellipsoidal shape (e.g., a circle) using a user interface device, such as a touchscreen, touchpad or mouse. The zoom function continues so long as a touchscreen or touchpad are touched, or a mouse button is depressed, and an ellipsoidal path is traced. Zoom-in or magnification scaling factor may be applied to an image in response to a clockwise path trace and a zoom-out or demagnification scaling factor may be applied to an image in response to a clockwise path trace, or vice versa. A visual aid may be presented on the display that may be followed to conduct the zoom function.

Method and apparatus for integrating manual input

TL;DR: In this paper, a simple proximity transduction circuit is placed under each electrode to maximize the signal-to-noise ratio and to reduce wiring complexity, and segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contacts and extracts shape, position and surface proximity features for each group.

Method and apparatus for recognizing gestures on a computer system

TL;DR: In this paper, a stroke is input by a user onto a computer screen, and the stroke is smoothed by reducing the number of points that represent the stroke, and angles between adjacent segments of the smoothed stroke and derivatives of the angles are calculated.
