Abstract

An apparatus including: a housing portion having a length, a width and a depth; and a display portion, including a touch sensitive display extending length-wise and width-wise, wherein the display portion is configured to move between a first position in which the display portion has been elevated relative to the housing by translational depth-wise movement and a second position in which the display portion has been lowered from the first position towards the housing by translational depth-wise movement and wherein the touch sensitive display is configured to detect any one of a plurality of locations at which a user touches the touch sensitive display.

Claims

1. An apparatus comprising:

a housing portion having a length, a width and a depth; and

a display portion, comprising a touch sensitive display extending length-wise and width-wise, wherein the display portion is configured to move between a first position in which the display portion has been elevated relative to the housing by translational depth-wise movement and a second position in which the display portion has been lowered from the first position towards the housing by translational depth-wise movement and wherein the touch sensitive display is configured to detect any one of a plurality of locations at which a user touches the touch sensitive display.

2. An apparatus as claimed in claim 1, wherein raising the display portion relative to the housing portion promotes the display portion relative to the housing portion by separating an upper surface of the touch sensitive display from an upper surface of the housing.

3. An apparatus as claimed in claim 1, wherein when the display portion is in the first position there is a depth-wise step change between a level of an exterior surface of the display portion and a level of an exterior surface of the housing portion

4. An apparatus as claimed in claim 1, wherein the housing portion comprises a recess extending length-wise and width-wise and sized to snugly receive the display portion and wherein the display portion is configured to move into the recess to attain the second position and to slide at least partially out of the recess to attain the first position.

5. An apparatus as claimed in claim 1, wherein the display portion retains the same orientation in the first position and the second position.

6. An apparatus as claimed in claim 1, wherein the touch sensitive display is flat and lies within a two-dimensional plane extending length-wise and width-wise, and wherein the translational movement of the display portion is normal to the two-dimensional plane.

7. An apparatus as claimed in claim 1, wherein the display portion is biased towards the first position and away from the second position, and wherein user touch actuation of the touch sensitive display causes the display portion to travel towards the housing portion from the first position to the second position.

8. An apparatus as claimed in claim 1 comprising a controller configured to enable and disable movement of the display portion relative to the housing portion.

9. An apparatus as claimed in claim 8 wherein the controller is configured:

to determine whether a detected touch input at the touch sensitive display is valid;

to enable travel of the display portion from the first position to the second position in response to the touch input if the detected touch input is valid; and

to prevent travel of the display portion in response to the touch input if the detected input is invalid.

10. An apparatus as claimed in claim 9, wherein a detected touch input is valid when a detected location at which a user touches the touch sensitive display corresponds which a location of an icon for touch input displayed on the touch sensitive display.

11. An apparatus as claimed in claim 8, wherein the controller is configured:

to detect a change in state of the apparatus;

to automatically control movement of the touch sensitive display from the second position to the first position.

12. An apparatus as claimed in claim 1, wherein when the display portion is in the second position the touch sensitive display is not operational for touch input and when the display portion is in the first position the touch sensitive display is operational for touch input.

14. An apparatus as claimed in claim 1, comprising:

wherein the touch sensitive display is planar extending in a plane;

and wherein the apparatus has a compact configuration in which the plane of the touch sensitive display lies in a reference plane fixed relative to the housing portion;

and an expanded configuration in which the plane of the touch sensitive display is elevated with respect to the reference plane and lies substantially parallel to the reference plane.

15. An apparatus as claimed in claim 14, wherein a vector normal to the plane of the touch sensitive display and fixed relative to the touch sensitive display has the same position and orientation in the compact configuration and the expanded configuration.

16. An apparatus as claimed in claim 14, wherein the housing portion circumscribes the display portion in the compact configuration.

27. A method as claimed in claim 14, wherein a detected touch input is valid when a detected location at which a user touches the touch sensitive display corresponds which a location of an icon for touch input displayed on the touch sensitive display.

28. A method as claimed in claim 14 comprising:

detecting a change in state of the apparatus; and

automatically controlling movement of the touch sensitive display from the second position to the first position.

13. (canceled)

17. A method comprising:

determining whether a detected touch input at a touch sensitive display is valid;

if the detected input is valid enabling travel of the touch sensitive display in response to the touch input; and

if the detected input is invalid preventing travel of the touch sensitive display in response to the touch input.

18. (canceled)

19. (canceled)

20. A method comprising:

detecting a change in state of an apparatus comprising a touch sensitive display;

automatically moving the touch sensitive display to an elevated position from which it can travel in response to touch input at the touch sensitive display.

21. A method as claimed in claim 20, wherein the change in state detected is a change from a state in which the touch sensitive display is not operable for touch input to a state in which touch sensitive display is operable for touch input.
