Method and device for analyzing two-dimension sensing information

#1. Field of the Invention

#The present invention relates to a method and device for analyzing two-dimension sensing information, and more particularly, to a method and device for analyzing two-dimension sensing information to determine touch related sensing information with inner lower values within outer high values and with the inner higher values within outer low values.

#2. Description of the Prior Art

#The present invention can be more fully understood by reading the following detailed description of the preferred embodiments, with reference made to the accompanying drawings, wherein:

#FIG. 1A is a schematic diagram depicting a prior-art touch sensitive device;

#FIG. 1B is a schematic diagram illustrating prior-art signal values;

#Some embodiments of the present invention are described in details below. However, in addition to the descriptions given below, the present invention can be applicable to other embodiments, and the scope of the present invention is not limited by such, rather by the scope of the claims. Moreover, for better understanding and clarity of the description, some components in the drawings may not necessary be drawn to scale, in which some may be exaggerated relative to others, and irrelevant parts are omitted.

#Sensing Information

#In the present invention, sensing information can be provided by a touch sensitive device for representing 1-D, 2-D or multi-dimensional statuses on the touch sensitive device. The sensing information can be obtained by one or more sensors and converted into a plurality of continuous signal values by one or more Analog-to-Digital converters to represent among or change in amount of detected charges, current, voltage, capacitance, impedance or other electrical characteristics. Sensing information can be obtained or transmitted alternately, sequentially or in parallel, and can be compounded into one or more signals. These are obvious to those having ordinary skill in the art.
