Displays for Mobile Devices that Detect User Inputs Using Touch and Tracking of User Input Objects
First Claim
Patent Images
1. A mobile device, comprising:
- a touch-sensitive display screen including an array of electromagnetic radiation detectors, wherein the array of electromagnetic radiation detectors is configured to generate an image of a user input object when the user input object is spaced apart from the display and wherein the touch-sensitive display is further configured to generate a touch signal in response to the display screen being touched by the user input object; and
a controller configured to identify a hotspot on the user input object, wherein the hotspot comprises a portion of the user input object at which contact between the user input object and the display screen is expected, and to identify a user input gesture in response to a pre-condition, a trigger, and a post-condition, at least one of which includes detection of the hotspot while the user input object is spaced apart from the display screen and at least one other of which includes the touch signal.

Abstract
A mobile device includes a touch-sensitive display screen including an array of electromagnetic radiation detectors. The array of electromagnetic radiation detectors is configured to generate an image of a user input object when the user input object is spaced apart from the display, and the touch-sensitive display is further configured to generate a touch signal in response to the display screen being touched by the user input object. The mobile device further includes a controller configured to identify use input gesture from a combination of the image of the user input object and the touch signal.

17. A method for detecting user input on a touch-sensitive display screen, comprising:
-
generating an image of a user input object positioned adjacent to and spaced apart from the touch-sensitive display screen using an array of electromagnetic detectors in the display; detecting a hotspot on the user input object, wherein the hotspot comprises a portion of the user input object at which contact between the user input object and the display screen is expected; generating a touch signal in response to the user input object touching the display screen; and identifying a user input in response to the image of the user input object and the touch signal;
wherein identifying the user input comprises identifying the user input in response to a pre-condition, a trigger, and a post-condition, at least one of which includes detection of the hotspot while the user input object is spaced apart from the display screen and at least one other of which includes detection of the user input object touching on the display screen. - View Dependent Claims (18, 19)

20. A touch-sensitive display system comprising:
-
a touch-sensitive display screen including an array of electromagnetic radiation detectors, wherein the array of electromagnetic radiation detectors is configured to generate an image of a user input object when the user input object is spaced apart from the display, and wherein the touch-sensitive display is further configured to generate a touch signal in response to the display screen being touched by the user input object; and a controller configured to identify a hotspot on the user input object, wherein the hotspot comprises a portion of the user input object at which contact between the user input object and the display screen is expected, and to identify a user input gesture in response to a pre-condition, a trigger, and a post-condition, at least one of which includes detection of the hotspot while the user input object is spaced apart from the display screen and at least one other of which includes the touch signal.
