“Apple’s ‘Input device having extendable nib’ describes a unique stylus with a number of different nib or tip configurations, each having its own properties for drawing on a multitouch surface like an iPad,” Mikey Campbell reports for AppleInsider. “Published by the U.S. Patent and Trademark Office on Thursday, the proposed invention also boasts on-board sensors for motion detection and a light sensor for sampling real-world colors.”

“In one embodiment, the system features light-transmissive nibs or strands through which data may pass to the touch screen or a processor on board the stylus. In this case, the touchscreen display may have cameras embedded beneath its surface to collect light information pumped out from an LED in the stylus,” Campbell reports. “Communicating via light, the stylus would be able to inform the tablet to change a line’s color, engage certain patterns, change brush types and even operate system functions.”

“In some forms, the stylus may be kitted with a sensor suite including accelerometers, gyroscopes and other motion-sensing components that relays stylus position and angle back to host tablet,” Campbell reports. “The array would be helpful in transmitting lean angle that may then output a wider stroke, mimicking the motion of a wide-tipped pen.”
