Touchpad providing screen cursor/pointer movement control |
摘要 |
<p>A plurality N of capacitance sensing cells are arranged in a row/column array top to cooperate with a fingertip and produce an output signal that controls the movement of a cursor/pointer across a display screen. The output of each individual sensing cell is connected to the corresponding individual node of a resistor array that has N nodes arranged in a similar row/column array. A centroid output of the resistor nodes in row configuration provides an output signal for control of cursor movement in a row direction. A centroid output of the resistor nodes in column configuration provides an output signal for control of cursor movement in an orthogonal column direction. A mass signal output of the row/column resistor mode array provides a switch on/off signal.</p> |
