Apple is working on a pen equipped with a camera ...
If Steve Jobs was highly critical of the use of the stylus at the presentation of the iPhone in January 2007, Apple engineers have worked on the subject yet as shown in this patent filed in November 2010 . It describes the operation of a pen using an optical sensor such as a camera placed in the stylus. The latter is used to determine the position and movement of the stylus as a function of the screen. It detects elements imperceptible to the eye on the smartphone's screen and communicates wirelessly with the device. This technology also allows taking into account the tilt sensor and a pen in this would support the notion of pressure. This pen could also pick one or more position sensors such as an accelerometer or a gyroscope to further improve accuracy.Obviously, nothing says that Apple will offer in the near future a usable product with a stylus. However, this type of patent shows that engineers are interested in the issue of the stylus which can be useful in certain situations and especially for certain professions such as architects, designers and artists in general for that doodle is essential. There are pens compatible with capacitive screens of iPhone and iPad, but they do not take into account the pressure, which could be possible via a simple pressure sensor and the integration of Bluetooth 4.0.
