Electronic device and gesture input method of item selection

摘要

An electronic device utilizes gesture input method of item selection to perform various input actions. An item of a plurality of items may represent, for example and without limitation, a character, a symbol, or an icon. One or more input sensors of the electronic device capture gesture navigation input and an item selection routine converts the input into a standard, magnitude independent pointer, and then determines the corresponding item. Since the selection is not determined by the exact direction and magnitude of the gesture input, selection accuracy can be greatly enhanced. By employing the item selection routine and standard pointers, item selection traverse paths can be cycled within a confined sensing region, thus selection speed can be improved and device size can be reduced. By memorizing the traverse paths, user can select a desired item without looking at the display, thereby being accessible to visually impaired users.

主权项

1. A method for a system that selects an item from a plurality of items based on gesture navigation input, comprising:
(a) assigning a predetermined item from said plurality of items as a temporary selected item; (b) providing a display means for displaying said temporary selected item; (c) providing a memory means for storing data of said temporary selected item in a history log; (d) providing an input means for receiving gesture navigation input; and (e) providing a controller, which will:
(i) convert said gesture navigation input into a standard pointer;(ii) replace said temporary selected item with a new item from said plurality of items; The replacement criteria comprises said standard pointer and data of said history log; and(iii) assigning said temporary selected item as final selected item if said temporary selected item is a desired item.
