The iPod touch screen senses the electrical charge emitted by fingertips and their movement So say if you have very long lovely nails or have a physical disability that keeps you from using your fingers, you won't be able to use the functions of the iPhone.
Pogo Stylus simulates a human finger's capacitance and can be held like a pencil or attached to a mouth stick. Last year we wrote about the iPhone problem for people with disabilities. A friend mentioned that he wanted a iPhone but because he could not move his hands and a regular stylus did not work, he couldn't use the iPhone or other Mac devices that used the technology. The Pogo stylus that costs between $20 and $25 could be a godsend for people with disabilities. It also has an adapter so that you can clip it on to the iPhone.
About the Pogo Stylus:
The Pogo Stylus features an ultra-light
aluminum body with an anodized finish and laser graphics. The soft
tip glides easily over the surface of the display, making it fun and
easy to sketch, draw characters, or just slide to unlock. Sized for
accuracy, it does away with the awkward typos and misfires common to
fingertip-only use.
Eliminating
fingers has the added benefit of keeping the screen free of smudges and
grease. Designed to firmly hug the contours of the iPhone and iPod
touch, the Pogo Stylus travel clip will keep your accessory secure and
close at hand.The Pogo Stylus features a soft, durable tip designed with the needs of mobile users in mind.
It is precision-formed to the perfect size for the keyboard keys
The designers of the Pogo Stylus, Ten One will not reveal what proprietary technology they used to make the stylus, but we figure they have used metal that has some kind of charge. The stylus is available at many online stores including Amazom.com.
