HTC will be launching a capacitive stylus shortly if a listing from UK retailer Clove is to be believed. The stylus is meant to be for the Windows Mobile-powered HTC HD2 with its 4.3-inch display. However, it highlights that HTC may be launching this accessory for other handsets too, especially as it is starting to use capacitive screens in most of its upcoming smartphones.
Capacitive touchscreens sense changes in electrical current, therefore need the electrons from your fingers to register a command. That is why a normal stylus or your fingernail won’t work. The capacitive stylus uses a magnetic head to recreate the current created by the touch of a finger, but with more precision than possible with a finger tip.
Whether Android needs it though, with its touch friendly interface, remains to be seen. I can get around the phone reasonably easy and for the tricky parts, the trackball always comes in handy. However, for those with bigger fingers, this could be just the solution you’re looking for. We’ll keep you informed with any developments.
