Abstract

An apparatus including a display configured to present an object; a touch sensitive input device configured to enable a user to make touch inputs, including trace inputs; and a processor configured to perform a geometric transformation of the object on the display in response to a sequence of distinct touch inputs of the touch sensitive input device, the sequence including a first touch input and a second touch input wherein the first touch input in the sequence defines an invariant point in the object and the second touch input in the sequence defines the geometric transformation.

a display configured to present an object;

a touch sensitive input device configured to enable a user to make touch inputs, including trace inputs; and

a processor configured to perform a geometric transformation of the object on the display in response to a sequence of distinct touch inputs of the touch sensitive input device, the sequence including a first touch input and a second touch input wherein the first touch input in the sequence defines an invariant point in the object and the second touch input in the sequence defines the geometric transformation.

2. An apparatus as claimed in claim 1 wherein the invariant point is defined as the point of the object at which the first touch input was made.

3. An apparatus as claimed in claim 2 wherein the processor is configured to control the display to present an indication of the invariant point once the invariant point has been defined.

4. An apparatus as claimed in claim 1 wherein the touch sensitive input device is configured to enable a user to make touch inputs via the display.

5. An apparatus as claimed in claim 4 wherein the first touch input is made via any region of the display in which the first object is presented.

6. An apparatus as claimed in claim 1 wherein the first input is a predetermined type of input.

7. An apparatus as claimed in claim 1 wherein the first touch input is the actuation of an area of the touch sensitive user input device for at least a predetermined time period.

8. An apparatus as claimed in claim 1 wherein the second touch input is a trace input.

9. An apparatus as claimed in claim 8 wherein the processor is configured to measure the trace of the second touch input with respect to the invariant point.

10. An apparatus as claimed in claim 8 wherein the trace of the second touch input starts anywhere within the region of the display in which the first object is presented.

11. An apparatus as claimed in claim 8 wherein the length and direction of the trace of the second touch input determines the geometric transformation.

12. An apparatus as claimed in claim 1 wherein the geometric transformation is a resealing of the object.

13. An apparatus as claimed in claim 1 wherein the geometric transformation is a rotation of the object about the invariant point.

14. A method comprising:

presenting an object on a display;

detecting a sequence of distinct touch inputs on a touch sensitive user input device, the sequence including a first touch input and a second touch input;

defining, in response to the detection of the first touch input, an invariant point of the object; and
