Disclosed is a computer-pointing device. A first sensing unit (42), a second sensing unit (44), and a control unit (40) are primarily disposed in the pointing device. The control unit (40) couples to the first sensing unit (42) and the second sensing unit (44). The control unit (40) receives a first move detection signal outputted by the first sensing unit (42), and receives a second move detection signal from the second sensing unit (44). The variance of the first move detection signal and/or the second move detection signal is referred to compute a cursor control signal. Further, the first sensing unit (42) or the second sensing unit (44) is slidably disposed in the device's casing (10). This movable sensing unit (42, 44) allows the cursor control correlated to the moving pointing device more accurate, more stable and/or faster responsive to the user's operation.
