Abstract

A flash content navigation method, a mobile electronic device, and a computer-readable medium are provided, wherein the flash content is embedded in a web page, and a visible area within the web page is predetermined for displaying at least a portion of the flash content. In the method, when receiving a flash navigating signal, a full screen interface is popped up. If a size of the visible area is greater than that of the touch screen, the flash content is scaled down to make the flash content displayed in the visible area fit the size of the touch screen, and the flash content displayed in the visible area is played back by a scaled size. When receiving a flash interacting signal from the touch screen, the flash interacting signal is transmitted to a flash engine to perform an action on the flash content according to the flash interacting signal.

when receiving a scene dragging signal and if an original size of the flash content is greater than the size of the visible area, transmitting the scene dragging signal to the flash engine to drag the flash content according to the scene dragging signal, so as to display different portion of the flash content in the visible area; and

when receiving a fit-to-screen signal, resizing the flash content to make the flash content displayed in the visible area fit the size of the touch screen.

5. The method as claimed in claim 4, wherein the step of resizing the flash content according to the resizing signal comprises:

if the resizing signal is generated according to a double-tap gesture on the touch screen, resizing the flash content to the original size of the flash content, so as to play back a partial of the flash content displayed in the visible area on the full screen interface; and

if the resizing signal is generated according to a pinch gesture on the touch screen, zooming the flash content according to the pinch gesture, so as to play back a partial of the flash content on the full screen interface.

6. The method as claimed in claim 4, wherein the viewpoint moving signal is generated according to a pan gesture on the touch screen, the scene dragging signal is generated according to a press and pan gesture on the touch screen, and the fit-to-screen signal is generated according to a double-tap gesture on the touch screen.

7. The method as claimed in claim 1, wherein the flash interacting signal is generated according to a pan gesture or a single-tap gesture on the touch screen, and the step of transmitting the flash interacting signal to the flash engine to perform the action on the flash content according to the flash interacting signal comprises:

transmitting the flash interacting signal to the flash engine to invoke the action corresponding to the pan gesture or the single-tap gesture.

8. The method as claimed in claim 1, further comprising:

when receiving an exit signal, closing the full screen interface;

presenting the web page by the browser; and

when receiving a signal from the touch screen, transmitting the signal to the browser.

9. The method as claimed in claim 1, wherein the flash content is a Shockwave Flash (SWF) format.

10. A mobile electronic device comprising:

a touch screen;

a flash engine providing module, for providing a flash engine and a flash engine interface;

a web page browsing module, coupled to the touch screen and the flash engine providing module, for launching a browser to retrieve and present a web page with a flash content on the touch screen, wherein the browser accesses the flash engine through the flash engine interface to render the flash content, and at least a portion of the flash content is displayed on a predetermined visible area within the web page; and

a flash content navigation module, coupled to the touch screen and the flash engine providing module, for popping up a full screen interface according to a size of the touch screen when receiving a flash navigating signal,
