Can not tap very precisely on capacitive touchscreen

18 Mar 2014

Some alternative options which may work better then the included stylus are described at these web pages.

With capacitive touchscreens, a wide tip stylus is better than a fine point tip stylus. A wide tip allows more contact points on the touchscreen to be activated at once, giving a better average as to where exactly the tap should be located on the screen. Some fine tip Active (battery operated) styli try to compensate for this by supplying their own charge, but this does not always work very well.

Basically, capacitive touchscreens were designed for use with finger taps instead of stylus taps. Application developers should avoid small buttons and crowded UI (user interface) elements. If these can not be avoided, we provide a hold-to-zoom feature to compensate when needed as demonstrated in this video.

Changing the current touchscreen profile may also help as described in this blog post.

Improvements to touchscreen behavior have also been integrated in OS release 1.4.4 or higher, which is available at this web page.

The quantity and quality of vendors of resistive touchscreens for mobile devices have diminished due to the consumer product trend with smartphones and tablets that similarly use capacitive touchscreens.
