Hello all - I've been tasked with determining if the capacitance touchscreen on a android device is sensitive enough to provide even a partial fingerprint. During my research I'm coming to the conclusion that no, most devices does not have enough electrodes to determine the variation between the ridge/valleys of a print but I'm also suspecting the hardware doesn't do much more than provide X,Y coordinates to the software.
My question is, when you develop for android is there a way to get access to the touchscreen raw data? An alternate, semi-related question, by chance does anyone here know how the hardware on a capacitance fingerprint scanner works differently than a capacitance touchscreen? It seems they utilize similar technology but perhaps the density of electrodes on a touchscreen is much less? I'm at a loss here. Thanks for your time. If I have missed any threads about this, please either give me some search terms so I can locate the thread or a link to the thread will be appreciated. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
