Abstract

The present invention relates to an improved method for enlarging or reducing scale of a displayed digital content within a display, said display having a touch sensitive portion reactive to a pointing means, the method including identifying a time specific touch on a point with said pointing means. It is determined that the identified time specific touch corresponds to an enlarging operation or a reducing operation of said displayed portion of said digital content within said display screen. The enlarging operation or the reducing operation are performed.

Claims

1. A method for enlarging or reducing scale of a displayed digital content within a display of a device, said display having a touch sensitive portion reactive to a pointing means, comprising:

identifying a time specific touch on a point with said pointing means;

determining that the identified time specific touch corresponds to an enlarging operation or a reducing operation of said displayed portion of said digital content within said display screen; and

performing the enlarging operation or the reducing operation.

2. The method of claim 1, wherein the enlarging or reducing operation is limited to a predetermined boundary.

3. The method of claim 2, wherein said predetermined boundary has a centre at said point.

4. The zooming method of claim 1, wherein the enlarging or reducing operation is based to number of touches of said touch sensitive portion.

5. A device, comprising:

a touch sensitive digital display configured to receive a touch input; and

a controller,

wherein said controller is configured to receive a signal from said display and, when it is determined that a received touch input corresponds to a scale altering touch, alter a scale of a content on said display.

6. The device of claim 5, further comprising a transceiver mechanism enabling the device to communicate with other devices or systems.

7. The device of claim 5, being incorporated in one of a mobile terminal or telephone, a digital media player, a camera, a personal digital assistant, or a computer.
