Abstract: A system for manual data input into computers, mobile phones or other electronic devices comprising a display device (70) and two pointing devices (60L, 60R) each equipped with a cluster of up to five finger-activated sensors (63). The display device presents a subset of characters from an alphabet and two rigid cursor patterns (40L, 40R) with up to five individual cursors representing operator's fingers. An operator uses motions of hands or thumbs to position the cursor patterns over the characters to be input and inputs them by using the finger-activated sensors. The system combines the functions of a keyboard and a pointing device and allows for data input utilizing all the fingers of operator's hands while looking only at the display device.

Abstract: An object of the present invention is to provide a method for creating an unique digital representation of multiple analog signals, and more particularly to provide a method for development of a sequential digital profile from selective incoming analog signals, for the future application in processing analog signals. The method is based performing on-line segmentation of incoming analog signals according to a sequence of threshold values. The results of the segmentation are represented by a sequence of measurements corresponding to selective attributes describing analog signals. Then, the results of segmentation performed for many incoming analog signals are generalized using selective rules, conditions, and algorithms, in order to develop a sequential digital profile from sequences of measurements.
