We have seen many styluses compatible with iDevices, whether we talk about iPad or iPhone, however, Blue Tiger, created by the people at Ten One Design, is an original product with a similar function.
Considered as the first pressure sensitive stylus, Blue Tiger is actually using a Bluetooth 4.0 connection to communicate with the iDevice. As technology, Bluetooth 4.0 is currently present only in the new iPad and iPhone 4S.
The magic of a pressure sensitive stylus is that, when drawing, the lines you draw can be thicker or thinner, and colors can be pale or deep. The new Bluetooth 4.0 standard allows no pairing interaction, while the new profile for low power consumption translates into the fact that the stylus can work without problems for several months or even a year on a single charge.
As additional functions, Ten One Design Blue Tiger integrates a led whose color changes in order to reflect the color chosen on the iPad. By using a separate protocol interaction, when using the stylus, the user should not worry if he leans a hand on the iPad because it will no longer be sensitive to human touch. Located in the final stages of approval from the FCC, the device seems to be in a commercial form, though may suffer some minor changes if needed.
If you are on a list of developers interested in this gadget, you have all chances to get it before the world. To download the SDK of this stylus, you have to visit official website of the manufacturer.
