Apple has given us illuminated keyboards, so why not illuminated touchpads? An Apple patent (number 20120206392) at the U.S. Patent & Trademark Office shows that the company may be working on just that.
The invention pertains to improved feedback mechanisms for touch pads. One aspect relates to devices capable of illuminating the touch sensitive surface of the touch pad. Another aspect relates to methods for providing visual feedback at the touch pad.
Here’s Apple’s summary of the invention: “The invention relates, in one embodiment, to an illuminated input device. The illuminated input device includes an object sensing mechanism capable of sensing a user input over an input surface. The illuminated input device also includes a visual feedback system configured to illuminate the input surface in association with a user input.
“The invention relates, in another embodiment, to a method of operating an input device. The method includes sensing an object over an input surface. The method also includes and illuminating at least a portion of the input surface when an object is sensed.
“The invention relates, in another embodiment, to a method of operating an input device. The method includes illuminating at least a portion of an input surface when an object is detected over the input surface. The method also includes adjusting the illumination when the object is moved over the input surface.
“The invention relates, in another embodiment, to a method of operating an input device. The method includes detecting a user input over the input surface. The method also includes determining an input state of the input device based on the user input. The method additionally includes illuminating the input surface based on the input state of the input device. Each input state having a different illumination profile.”
Stanley C. Ng and Duncan Robert Kerr are the inventors.
