Apple has filed for a patent (quantity US 20240118773 A1) for a “Picture-Sensing Enabled Show For Stylus Detection.” It entails an Apple Pencil that pulls its energy from the iPad — and possibly even an iPhone. Apple Watch, and Mac — as a substitute of needing charging.
Concerning the patent submitting
In previous and present iterations of the Pencil, you needed to join it to an iPad for charging or use a USB-C connector. Future variations might be a “no-power” stylus that pulls energy when its used to jot down or draw on a tool resembling an iPad, iPhone, or Apple Watch.
And there’s extra to the patent submitting. It additionally entails an Apple Pencil with an optical sensing system that works along with an optical stylus to find out a number of of the goal or contact location, centroid, hover distance, tilt angle, azimuth, and in some cases the orientation and rotation of the stylus.
Abstract of the patent submitting
Right here’s Apple’s summary of the patent submitting: “An optical stylus system together with an optical stylus and optical sensing system which are collectively operative to find out a number of of the goal or contact location, centroid, hover distance, tilt angle, azimuth, and in some cases the orientation and rotation of the stylus is disclosed. In some examples, gentle illuminator and detector angular filters are employed to restrict the illumination and detection angles of sunshine to attenuate false object detection.
“In different examples, the stylus is a passive stylus with a floor that displays gentle with a constant angular reflection profile or mirrored gentle sample no matter stylus tilt. In nonetheless different examples, the stylus can detect gentle at totally different modulation frequencies emitted from an array of sunshine emitters within the optical sensing system, or the stylus can emit gentle and detect mirrored gentle with totally different spectral distributions throughout the optical sensing system to find out stylus location.”
