Embodiment Construction

[0023] Touch screen technology is commonly used in exemplary electronic computing devices such as tablet computers, personal digital assistants (PDAs), audio and video control systems, portable music and video players, and cell phones and satellite phones. Such electronic computing devices include a touch screen interface as a user interface. A touch screen interface includes a touch-sensitive surface (hereinafter referred to as a touch screen) and a display screen. The touchscreen covers a designated portion of the display.

[0024] Conventional touchscreen technology may enable a user of an electronic computing device to expand an area of ​​graphical information and / or textual information displayed on a display screen after the touchscreen detects or registers a touch event. However, traditional touchscreen technology has limitations. For example, traditional touch screen technology does not allow users to actively control the magnification (or magnification) of the magnif...

Abstract

A user interface including a display screen and an input device. The input device is for example a touchscreen, a touch pad, and one or more proximity sensors. The input device detects an input event, more specifically a pointing object placed in proximity therewith. Parameters of the input event include distance of the pointing object from the input device, speed of displacement of the pointing object towards the input device, direction of displacement of the pointing object towards the input device, and direction of displacement of the pointing object relative a plane of the input device. The display screen effects output events or magnification events. A field of view on the display screen (i.e. an area on the display screen) is magnified.; At least one of scale of magnification, size of field of view to be magnified and size of resultant magnified field of view is dependent on at least one of the parameters of the input event. A user interface method for controlling magnification events effected by the display screen in response to signals generated by the input device is also provided by the present disclosure.

Description

technical field [0001] The present invention generally relates to touch screen technology for electronic devices. More specifically, the present invention relates to touch screen technology implemented in portable electronic devices for converting input events into images displayed on a display screen with controlled magnification. Background technique [0002] The use of touch screen interfaces is becoming more common in exemplary electronic computing devices such as tablet computers, personal digital assistants (PDAs), handheld audio and video control systems, portable music and video players, and cell phones and satellite phones . This is mainly due to the ease of use, versatility and aesthetics of the touchscreen interface. A touch screen interface generally includes a touch-sensitive surface (which may be referred to as a touch screen) and a display screen. The touch-sensitive surface, ie, the touch screen, typically covers or is coextensive with a designated portion...
