“On June 18, 2015, the European Patent Office published a patent application from Apple that reveals their invention related to the Apple Watch’s Digital Crown,” Jack Purcher reports for Patently Apple. “The patent reviews an input Friction Mechanism that provides the Digital Crown with its haptic feedback and more.”
“Apple’s invention generally relates to inputs of electronic devices, and more particularly relates to rotary inputs used with electronic devices such as the Apple Watch and its Digital Crown,” Purcher reports. “According to one broad aspect of one embodiment is an apparatus for an electronic device that provides haptic feedback by controlling an application of friction to a rotary input control with a shaft.”
Purcher reports, “Apple notes that in one example, the electronic device may be configured in the form of a wearable health assistant that provides health-related information (whether real-time or not) to the user, authorized third parties, and/or an associated monitoring device.”
