Interesting Apple patent on pen input

The current generation of iOS devices are all about finger input. However, a recently-awarded patent shows that Cupertino is seriously exploring pen input.

The current generation of iOS devices — iPhone, iPod and iPad — are all about finger input. While there are a number of capacitive pens on the market, Apple's device isn't specifically designed with a stylus in mind. However, a recently-awarded patent shows that Cupertino is seriously exploring pen input.

The report at Patently Apple shows a future stylus that ends with a small conductive disk instead of the current pens that end in plastic foam or rubber. The stylus has a ball tip that would pivot, keeping the disk in contact with the screen.

In some embodiments, stylus functionality may also include sensory modules including motion or pressure sensors and other similar devices. In certain embodiments, the stylus could include one or more squeeze (force) sensors, switches, buttons and/or other toggles adapted to allow a user to quickly select among various types of associated functionality (for example, selecting colors, brush sizes, shading, line width, eraser functionality, etc.).
