Abstract

Techniques are disclosed that involve projection interfaces, such as multitouch projected displays (MTPDs). For example, a user may activate a projection interface without having to interact with the a non-projected interface (e.g., a keyboard or keypad). Also, a user may select or adjust various device settings. Moreover, various user applications may be allocated among a projected interface and another display (e.g., an integrated display device). Such techniques may be employed in various environments, such as ones in which a display input devices exist in addition to a projection interface. Through such techniques, ease of use for projection interfaces may be advantageously achieved.

Claims

1. A method, comprising:

receiving a user activation request for a projected user interface at a computing device having a display device, a non-projected interface, and a projector, the request being in the form of a predetermined user gesture in a predetermined detection region of a gesture sensor module of the computing device;

wherein receiving the user activation request comprises detecting a user gesture through a gesture sensor module independent of the non-projected interface and independent of any keyboard, touchpad, and buttons of the computing device;

based on the user activation request, activating the projected user interface by projecting the projected user interface onto a surface using the projector and registering touches on the surface;

wherein the projected user interface presents a device settings menu, the menu providing one or more setting selections to adjust the projected user interface independent of setting selections for the display device; and

wherein the menu is to allow the user to select among a plurality of display modes with respect to the display device and the projector, the plurality of display modes comprising a duplicate display mode, an extended desktop mode, and an appliance mode.

2. The method of claim 1, further comprising providing a user login dialog through the projected user interface based on the user activation request before presenting the device settings menu, the login dialog requiring a user authentication before providing access to some but not all applications of the computing device.

3. The method of claim 1, further comprising:

receiving a move gesture at the gesture sensor module related to an application window on the display device;

providing an allocation of a plurality of applications between the projected user interface and the display device;

allocating the application window on the display device to the projected user interface based on the move gesture.

4. The method of claim 3, further comprising:

receiving a user selection to change the allocation of applications between the projected user interface and the display device as selecting and dragging an icon on the projected user interface; and

changing the allocation based on the user selection.

5. The method of claim 4, wherein receiving the user selection to change the allocation comprises detecting a user gesture.

6. The method of claim 1, further comprising receiving a selection of a color scheme for the projected user interface on the device settings menu of the projected user interface;

and

modifying the color scheme of only the projected user interface based on the selection.

7. The method of claim 6, further comprising:

storing a color scheme database that includes configuration information for multiple color schemes for a projected user interface;

receiving measurements conveying characteristics of a currently projected projection interface from a projection interface control module; and

selecting a stored color scheme upon receiving the user activation request wherein said selecting is performed automatically based on the received measurements.

8. The method of claim 6, wherein said receiving a selection is a selection of a stored color scheme from the user.

9. The method of claim 1, wherein the projected user interface comprises a multi-touch projected display (MTPD).

10. The method of claim 1, further comprising:

allocating user gesture commands to application(s) provided by one of the projected user interface and the display device; and

allocating user voice commands to application(s) provided by one of the projected user interface and the display device.

11. An apparatus, comprising:

a device including a projector to provide a projected user interface;

a display device;

a non-projected interface;

a gesture sensor module to receive a user activation request to activate the projected user interface, the request being in the form of a predetermined user gesture in a predetermined detection region of a gesture sensor module of the computing device;

a user interface management module to provide a device settings menu through the projected user interface in response to the received request;

wherein the menu provides one or more setting selections to adjust the projected user interface independent of setting selections for the display device; and

wherein the menu is to allow the user to select among a plurality of display modes with respect to the display device and the projector, the plurality of display modes comprising a duplicate display mode, an extended desktop mode, and an appliance mode; and

wherein the user interface management module is to cause an activation of the projected user interface upon receipt of a user activation request gesture received independent of the non-projected interface and independent of any keyboard, touchpad, and buttons of the computing device.

12. The apparatus of claim 11, wherein the user interface management module is to provide an allocation of a plurality of applications among the projected user interface and the display device by receiving a move gesture at the gesture sensor module related to an application window on the display device and allocating the application window on the display device to the projected user interface.

13. The apparatus of claim 12, wherein the allocation is based on a user selection and on allocation data stored in the computing device the allocation data including output and input features for the projected user interface.

14. The apparatus of claim 13, wherein the user selection is a user gesture detected by the gesture sensor module as selecting and dragging an icon on the projected user interface.

15. The apparatus of claim 11, wherein the predetermined detection region is in proximity of the display device.

16. The apparatus of claim 11, wherein the apparatus is one of a notebook personal computer, a desktop personal computer, and a tablet personal computer.

17. An article comprising a non-transitory machine-readable medium having stored thereon instructions that, when executed by the machine, cause the machine to:

receive a user activation request for a projected user interface at a computing device having a display device, a non-projected interface, and a projector, the request being in the form of a predetermined user gesture in a predetermined detection region of a gesture sensor module of the computing device;

wherein receiving the user activation request comprises detecting a user gesture through a gesture sensor module independent of the non-projected interface and independent of any keyboard, touchpad, and buttons of the computing device;

based on the user activation request, activate the projected user interface by projecting the projected user interface onto a surface using the projector and registering touches on the surface;

wherein the projected user interface presents a device settings menu, the menu providing one or more setting selections to adjust the projected user interface independent of setting selections for the display device; and

wherein the menu is to allow the user to select among a plurality of display modes with respect to the display device and the projector, the plurality of display modes comprising a duplicate display mode, an extended desktop mode, and an appliance mode.
