Abstract

An apparatus, method, and computer program product are provided for generating a projected user interface. The apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured, with the processor, to cause the apparatus to receive information regarding a detected position of the user'"'"'s body and to determine whether the detected position is an activation position, in which case the projection of a user interface may be provided. The user interface may be projected on an area on the user'"'"'s body, such as a hand or a forearm, or on the surface of an object. The activation position may thus be a predefined position of the user'"'"'s body in which effective projection of the user interface onto the surface and user interaction with the user interface is facilitated.

Claims

1. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

receive information regarding a detected position of at least part of a user'"'"'s body;

determine whether the detected position comprises an activation position; and

provide for projection of a user interface onto a surface in response to the determination that the detected position comprises the activation position,

wherein the activation position is a predefined position of the part of the user'"'"'s body in which effective projection of the user interface onto the surface and user interaction with the user interface is facilitated.

2. The apparatus of claim 1, wherein causing the apparatus to receive information regarding the detected position comprises causing the apparatus to receive information regarding a relative position of at least two sensors with respect to each other.

3. The apparatus of claim 1, wherein causing the apparatus to receive information regarding the detected position comprises causing the apparatus to receive information regarding a physiological measurement.

4. The apparatus of claim 1, wherein causing the apparatus to receive information regarding the detected position comprises causing the apparatus to receive information regarding a position of a predetermined part of the user'"'"'s body with respect to a predefined point on the user'"'"'s body.

5. The apparatus of claim 1, wherein the memory and computer program code are further configured to, with the processor, cause the apparatus to receive an input from the user confirming that activation of the user interface is desired, wherein the projection of the user interface is provided in response to the determination that the detected position comprises the activation position and receipt of the input.

6. The apparatus of claim 1, wherein the activation position comprises a position in which a backside of the user'"'"'s hand is disposed proximate the user'"'"'s forearm such that projection of the user interface onto the backside of the user'"'"'s hand from a source disposed on the user'"'"'s forearm is facilitated.

7. The apparatus of claim 1, wherein the activation position comprises a position in which a palm of the user'"'"'s hand is disposed proximate an underside of the user'"'"'s forearm such that projection of the user interface from a source disposed on the underside of the user'"'"'s forearm onto the palm of the user'"'"'s hand is facilitated.

8. The apparatus of claim 1, wherein the activation position comprises a position in which at least one finger of the user'"'"'s hand is disposed proximate the user'"'"'s palm such that projection of the user interface onto the palm of the user'"'"'s hand from a source disposed on one of the user'"'"'s fingers is facilitated.

9. The apparatus of claim 1, wherein the activation position comprises at least two positions achieved in succession.

10. The apparatus of claim 1, wherein the surface upon which the projection is provided comprises a surface of an object.

11. The apparatus of claim 1, wherein the surface upon which the projection is provided comprises a surface of the user'"'"'s body.

12. The apparatus of claim 1, wherein the memory and computer program code are further configured to, with the processor, cause the apparatus to discontinue the projection of the user interface onto the surface when the detected position is substantially different from the activation position.

13. A method comprising:

receiving information regarding a detected position of at least part of a user'"'"'s body;

determining via a processor whether the detected position comprises an activation position; and

providing for projection of a user interface onto a surface in response to the determination that the detected position comprises the activation position,

wherein the activation position is a predefined position of the part of the user'"'"'s body in which effective projection of the user interface onto the surface and user interaction with the user interface is facilitated.

14. The method of claim 13, wherein receiving information comprises receiving information regarding a relative position of at least two sensors disposed on the user'"'"'s body with respect to each other.

15. The method of claim 13, wherein receiving information comprises receiving information regarding a physiological measurement.

16. The method of claim 13, wherein receiving information comprises receiving information regarding a position of a predetermined part of the user'"'"'s body with respect to a predefined point on the user'"'"'s body.

17. The method of claim 13, wherein determining whether the detected position comprises the activation position comprises determining via a processor whether the detected position and the activation position have at least a predefined percentage in common.

18. The method of claim 13 further comprising discontinuing the projection of the user interface onto the surface when the detected position is substantially different from the activation position.

19. A computer program product comprising at least one computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising program code instructions for:

receiving information regarding a detected position of at least part of a user'"'"'s body;

determining whether the detected position comprises an activation position; and

providing for projection of a user interface onto a surface in response to the determination that the detected position comprises the activation position,

wherein the activation position is a predefined position of the part of the user'"'"'s body in which effective projection of the user interface onto the surface and user interaction with the user interface is facilitated.

20. The computer program product of claim 19, wherein the program code instructions for determining whether the detected position comprises the activation position include instructions for determining whether the detected position and the activation position have at least a predefined percentage in common.
