Capacitive displays? You dont need no stinking capacitive displays! ... says Microsoft June 30, 2009 [General] | By Edward J. R. In an article for developers about finger gestures in Windows Mobile 6.5, an employee of Microsoft more or less says that resisitive displays are better because they are cheaper and make handwriting recognition easier, but also mentions that some manufacturers consider making phones powered by Windows Mobile 6.5 with capacitive displays: Capacitive technology has several advantages: zero pressure is required to make an input because nothing needs to be deformed and this leads to a much more natural interface experience; although additional material is laid onto the screen, there is no air gap so optical clarity is much improved reducing the need for backlighting making power draw lower; multiple touch points can be supported; things like touch size and pressure can be extrapolated from the capacitive data. However they do suffer in other areas: in general the cost is currently higher than the equivalent resistive screen; supporting a stylus is hard because it must be made of conducting material and must make sufficient contact to change the capacitive property of the screen; in several areas the accuracy tends to be lower than resistive e.g. around the edges of the screen, combined with the lack of a stylus and lower sample rates makes things like handwriting input very hard. Windows Mobile 6.5 has primarily been designed for resistive screens because some input areas still rely on small controls and require a high level of input accuracy that can’t be easily achieved with a finger and require a stylus; however some device manufacturers are considering options to ship capacitive screens. To learn more, please read: Let’s Talk About Touch by Marcus Perryman from Microsoft. Commentary: Microsoft should stop whining that capacitive displays are more expensive and no good for handwriting recognition but instead Microsoft should realize something: users now expect "zero pressure is required" and when they try to use Windows Mobile phones with touchscreen, then they have impression that these phones are broken and simply don't buy them...
