Abstract

A handheld digital drawing and projection device is provided. The device includes a screen for receiving a user input. In embodiments, a stylus tethered to the device provides the user input at the screen. The device further includes a determining component for determining an output corresponding to the received user input. A projector for projecting the determined output onto an external projection surface is also included. In some embodiments, the projector further projects a display environment, which includes one or more projected elements.

Claims

1. A handheld digital drawing and projection device comprising:

a screen for receiving a user input;

a determining component for determining an output corresponding to the received user input; and

a projector for projecting the determined output onto an external projection surface, wherein the projector further projects a display environment comprising one or more display environment elements that provide context for a user-drawn projection received via the screen and projected simultaneously with the display environment based on the determined output.

2. The device of claim 1, further comprising a stylus for providing the user input at the screen, wherein the stylus is tethered to the device, and further wherein the determining component senses an amount of pressure applied to the screen via the stylus, the amount of pressure corresponding to at least one function associated with the device.

3. The device of claim 1, further comprising a sensing component for sensing at least one of an acceleration of the device, an orientation of the device, and a magnetic field around the device, wherein the determined output projected onto an external surface corresponds to one or more of a sensed acceleration of the device, a sensed orientation of the device, and a sensed magnetic field around the device.

4. The device of claim 3, further comprising a selecting component included in the handheld device for selecting an image to be projected by the projector, the selected image based on the at least one of the sensed acceleration of the device, orientation of the device, and magnetic field around the device, and the output determined by the determining component.

5. The device of claim 4, wherein a particular image is selected based on a particular orientation of the device, the particular orientation of the device corresponding to a particular portion of an external projection surface, such that when the sensing component senses the particular orientation of the device, the selecting component selects the particular image to be projected and the projector projects the particular image onto the particular portion of the external projection surface, said particular image comprising at least a portion of a 360-degree projection environment.

6. The device of claim 4, wherein the selected image includes the determined output corresponding to the received user input and at least a portion of the display environment comprising one or more projected elements.

7. The device of claim 3, wherein the determined output is altered to provide an altered output based on the at least one of the sensed acceleration of the device, orientation of the device, and magnetic field around the device.

8. The device of claim 7, wherein the altered output is a mirror reflection of the determined output based on the sensed acceleration of the device.

9. A method for projecting an interactive display onto an external projection surface, the method comprising:

receiving a user input on a screen of a handheld digital drawing and projection device, the handheld digital drawing and projection device comprising;

a screen for receiving a user input,

a determining component for determining an output corresponding to the received user input,

a projector for projecting the determined output onto the external projection surface; and

a speaker;

at the determining component, determining the output corresponding to the received user input for projection onto the external projection surface;

at the projector, projecting the determined output onto the external projection surface; and

at the speaker, providing at least one of an audio output selected by the user and an automatically provided audio output corresponding to the determined output for projecting.

10. The method of claim 9, wherein the handheld digital drawing and projection device further comprises a selecting component for selecting an image to be projected on a particular portion of the external projection surface, the selected image based on at least one of an acceleration of the device, orientation of the device, and magnetic field around the device.

11. The method of claim 9, wherein the selected image comprises the determined output and a display environment.

12. The method of claim 9, wherein the projector further projects a display environment, the display environment comprising one or more projected elements.

13. A handheld digital drawing and projection device comprising:

a rear end comprising a rear handle portion and a screen for receiving a user input;

a front end opposite said rear end, said front end comprising a lens through which an output corresponding to the received user input is projected;

an intermediate portion positioned between the rear end and the front end and comprising an intermediate handle portion;

a cartridge slot configured to receive a cartridge;

a stylus for providing the user input at the screen;

a tether for tethering the stylus to a body of the handheld digital drawing and projection device;

a stylus holding compartment configured to hold the stylus;

a data port for recharging a rechargeable battery of the device wherein the data port is configured to send and receive data at the device;

a speaker; and

at least one sensor for detecting a movement, acceleration, and orientation of the device.

14. The device of claim 13, wherein the intermediate portion comprises an intermediate portion width that is smaller in size than a front end width of the front end and a rear end width of the rear end.

15. The device of claim 13, wherein the screen is a touch screen that receives the user input based on contact between the touch screen and the stylus to provide a change in capacitance with respect to the screen.

16. The device of claim 13, wherein the at least one sensor includes an accelerometer and a magnetometer.

17. The device of claim 16, wherein the accelerometer and the magnetometer enable the device to selectively project a particular image on a particular portion of an external projection surface.
