hey guys it's brandon minuman from pocket now calm as you probably know a capacitive touchscreen such as that found on the HTC hd2 the google nexus one and the iphone do not respond to a traditional stylus that is because they require a change in capacitance to register a screen press there is an electrostatic field over all of these screens and the only way that they know where you've hit is by a little bit of electricity in your finger changing the capacitance of a certain area on the screen whereas on a resistive touchscreen it's all done by pressure and that's why any object including a stylist will work but if you get a capacitive stylus such as this one that I got off of ebay for about five or six dollars you can actually use a stylus with any of these devices or any device that has a capacitive touchscreen let's take a look so here we have the nexus one I can easily unlock that the hd2 and the iphone HTC is actually selling or is going to be selling an HTC branded capacitive stylus for use with their devices although obviously they will work with any device with a capacitive touchscreen so why would you want a capacitive stylus well there are a few reasons that I can think of first and foremost is that when you have gloves on you can't use the touch screen on your capacitive touchscreen device and having a capacitive stylus in your pocket when you're wearing gloves will really help out with that another way that a capacitive stylus helps is when you're doing any sort of painting application or you're doing handwriting recognition so we can scroll down here to say the notes application and sort of demonstrate this we can write something with our finger like hey and it's not very precise on a capacitive screen we can be a little bit better when we use a capacitive stylus but not chip not much better it's not perfect because capacitive touchscreens aren't particularly precise so i'll post a link on pocketnow.com on how to get this capacitive stylus it's very inexpensive and as you can see it works quite well to operate the screen that's it for now
