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.

Claims

1. A finger gesture user interface for an electronic device comprising:

a first housing section in which a display is mounted;

a second housing section comprising;

a front opening in a front outer surface of the second housing section;

a rear opening in a rear outer surface of the second housing section;

inner sidewalls extending from said front opening to said rear opening to form a cavity piercing the second housing section; and

a detector mounted in said inner sidewalls, operable to detect a finger inserted in the cavity;

a hinge joining said first and second housing sections that enables alternately (a) folding the second section on top of the display such that a finger touching the display is inserted into the cavity through said front opening, and (b) folding the second section under the first housing section such that a finger touching an exposed rear surface of the first housing section is inserted into the cavity through said rear opening; and

a processor connected to said detector for interpreting the finger touching the display as a first user interface input command, and for interpreting the finger touching the exposed rear surface of the first housing section as a second user interface input command.

2. The user interface of claim 1, wherein said detector is further operable to detect at least-five location and orientation attributes in response to the finger being inserted inside the cavity;

namely,

(i) location along an x-axis;

(ii) location along a y-axis;

(iii) location along a z-axis;

(iv) polar angle in the xz-plane; and

(v) polar angle in the yz-plane,

wherein the locations and polar angles are with reference to x and y axes along the length and width of the front opening of the cavity and to a z axis along the height of the cavity from front to rear.

3. The user interface of claim 1, wherein said detector is further operable to detect a multi-finger spread gesture and a multi-finger pinch gesture inside the cavity.

4. The user interface of claim 3, wherein said processor interprets the detected multi-finger spread gesture as a user interface input command to open a widget, document, web page, album or photograph.

5. The user interface of claim 3, wherein said processor interprets the detected multi-finger pinch gesture as a user interface input command to close an open widget, document, web page, album or photograph.

6. The user interface of claim 1, wherein said detector is further operable to detect a speed of insertion of the finger along the height of the cavity between front and rear, and wherein an attribute of the user interface input command is configured according to the speed.

7. The user interface of claim 1, wherein said detector is further operable to detect two polar angles of the finger inside the cavity with reference to x and y axes along the length and width of the front opening of the cavity and to a z axis along the height of the cavity from front to rear, namely,

(i) polar angle in the xz-plane;

and

(ii) polar angle in the yz-plane,

and wherein said processor interprets changes in the polar angles as user interface input commands.

8. The user interface of claim 7, wherein a gesture comprising tilting the finger inside the cavity causes said display to render a pop-up menu.

9. The user interface of claim 1, wherein said detector is further operable to detect a multi-finger rotation gesture inside the cavity.

10. The user interface of claim 9, wherein said processor causes said display to render a rotation of a displayed image, in response to said detector detecting the multi-finger rotation gesture.
