Apple has a new patent (via AppleInsider) for 3D gesture control, specifically describing the tech used to help a computer identify hand motions made by a user. The patent goes into detail about how the system can not only recognize gestures, but learn them so well that it can even spot them when part of the hand making the gesture is blocked or not visible by the camera, leading to greater accuracy overall.
A number of modern computing devices, like Apple's iPhone and iPad, incorporate touch-sensitive panels that enhance and define the user experience by affording unprecedented GUI manipulation and control. Some systems also incorporate what is known as "hover" controls, which allow users to interface with a device without actually touching it.
Using specialized internal components, these touch sensitive devices can recognize an object hovering above a display panel, like a user's finger or stylus. Once a hover event has been detected, the device may process it as a touch event, handling subsequent actions according to the general rules of traditional touch input. For example, if a hover event occurs over a specific app, that app may be opened.
"The U.S. Patent and Trademark Office on Tuesday awarded Apple a patent that describes a method for efficiently manufacturing curved touch surfaces, suggesting the company may be experimenting with curved iOS device displays."
With its U.S. Patent No. 8,581,870 for "Touch-sensitive button with two levels," Apple may be on the verge of introducing a new form of input; one that could change the face of iOS.
While a majority of the patent refers to a "button," a notation buried near the end of the document points out that a touch screen operatively coupled to an actuator can be considered a "touch-sensitive depressible button".
Apple's touchscreens can measure not only where you tap, but also how hard you tap — and that velocity sensing functionality may become even more advanced in the future, a new patent application reveals. The filing, entitled "System and Method for Enhancing Touch Input," describes a processing algorithm that would estimate the velocity of a touch input. The sensors within an iOS device or otherwise allow the system to determine velocity, even though the screen may not be pressure sensitive.
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for processing user input. A system configured to practice the method first receives, via a touch screen of a computing device, input from a user. Then the system fetches data associated with the input from at least two sensors other than the touch screen and adjusts an input processing algorithm based on the input and the data to yield an adjusted input processing algorithm. Then the system can process the input according the adjusted input processing algorithm. The adjusted input processing algorithm can estimate a velocity of the input and/or filter out invalid inputs. The other sensors besides the touch screen can be an accelerometer, a gyroscope, a microphone, a Hall Effect sensor, a compass, an ambient light sensor, a proximity sensor, a camera, and/or a positioning system. The data can relate to the input based on a temporal relationship.
