Apparatus and method for touch screen user interface for handheld electric devices part II

摘要

A system of touch screen user interface in a touch screen equipped handheld electronic device has a bounded control area on a touch screen that is used for touch control in lieu of the entire touch screen surface. The control area is able to provide touch control user interface functions of scroll, zoom, action item selection, and other control functions. The control area may be minimized enabling the entire touch screen to resume its touch screen control function in lieu of the control area control and maximized enabling only the bounded control area to be used for touch screen control depending upon a user's preference. The bounded control area for selection control functions may be used in conjunction with unique type of hop-cursors, for different types of displays that change automatically when the display content changes.

主权项

1. A system of touch screen user interface in a handheld device comprising:
a. the handheld device is of a type of a smart phone or a tablet computer and has a CPU, a memory, a storage, and a logic stored in the memory, the logic executing in the CPU simulates a bounded touch control area on a part of a touch screen display of the handheld device, the bounded touch control area is used for touch control in lieu of an entire touch screen display surface of the device; b. the logic simulates the bounded touch control area as an overlay over the part of the touch screen display for exclusive use as a touch control interface and does not display digital content from the device on the area; c. the logic enables the bounded touch control area to provide touch control user interface functions that include a sequence of at least one touch and slide-touch actions to control operation of the device, thereby enabling the device to be touch controlled from the bounded touch control area alone and the logic enables the bounded touch control area to be minimized for then the entire touch screen to be used for touch control.
