Benefits of technology

[0011]There is additionally provided in accordance with an embodiment of the present invention an electronic device including a light-based touch screen display and a cavity, separated from the display, penetrating two opposite sides of the housing, for providing light-based detection of user gestures performed in the cavity. Both the light-based touch screen display and the finger-gesture cavity are surrounded by pluralities of emitters and receivers mounted in the housing operative to detect objects touching the screen or inserted in the cavity, respectively. A controller in the housing is connected to both sets of emitters and receivers, for executing scan sequences thereon, and a processor is provided in the housing to receive the respective detection signals and determine the location of one or more touches on the screen and also to determine a user gesture of an object inserted inside the cavity.

Problems solved by technology

One of the drawbacks of touch screen input is that the user's hand blocks the user's view of the screen.
It will thus be appreciated that conventional touch screens are not ideal for finger gesture input.

Embodiment Construction

[0041]Aspects of the present invention relate to user input to electronic devices, and in particular, to a hollow cavity or a recessed cavity provided in a device housing separate from the device display operable to detect user input gestures performed in the cavity. The input gestures may be one-finger gestures, such as sliding a finger, or multi-finger gestures, such as a two-finger rotation, a two-finger pinch or a two-finger spread. The present invention further provides a light-based user interface that detects position and orientation of an object inserted within the cavity, which has application to three-dimensional touch recognition and to three-dimensional modeling, as described hereinbelow. The invention is described with regard to light based detection apparatus but other detection methods, such as acoustic methods, are also within the scope of the invention.

[0042]For clarity of exposition, throughout the present specification, the term “emitter” is used as a generic term...

Abstract

A light-based finger gesture user interface for an electronic device including a housing for an electronic device, a display mounted in the housing, a cavity, separated from the display, penetrating two opposite sides of the housing, a detector mounted in the housing operative to detect an object inserted in the cavity, and a processor connected to the detector and to the display for causing the display to render a visual representation in response to output from the detector.

Description

CROSS REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority benefit of U.S. Provisional Patent Application No. 61 / 564,868, entitled LIGHT-BASED FINGER GESTURE USER INTERFACE, filed on Nov. 30, 2011 by inventors Thomas Eriksson, Per Leine, Jochen Laveno Mangelsdorff, Robert Pettersson and Anders Jansson.FIELD OF THE INVENTION[0002]The field of the present invention is touch-sensitive screens.BACKGROUND OF THE INVENTION[0003]Many consumer electronic devices are now being built with touch sensitive screens, for use with finger or stylus touch user inputs. These devices range from small screen devices such as mobile phones and car entertainment systems, to mid-size screen devices such as notebook computers, to large screen devices such as check-in stations at airports.[0004]User input to a touch sensitive screen has evolved from basic screen taps to sweep gestures and to more elaborate pinch gestures involving coordinated, simultaneous input from two or more fingers. ...
