Apple Patents Touchscreen Improvements and Heart Monitor Tech
Two newly granted Apple (NASDAQ:AAPL) patents uncovered by Apple Insider could give the California-based company’s future mobile devices several new fascinating capabilities. In the first patent, titled “Touch and hover signal drift compensation,” Apple outlined a method for increasing the accuracy of its touchscreen panels for both direct contact events and hover events.
As noted in the patent’s background information, “While touch and hover capabilities in a touch sensitive device are desirable, together they can present a challenge to cooperative performance for accurate, reliable detection of touch and hover events.” A problem with combining touch and hover capabilities into one panel are “incidental touch events.”
For example, a panel may not register a user’s intended “hover event” if the event is masked by an incidental touch. This often occurs when the user’s hand that is holding the device accidentally touches the edge of the screen. In the patent, Apple outlined a method that would allow the device to discern the user’s intent based on certain input thresholds.
