Patent ID: 7761390

Claim:
An interactive communication method for a user responsive to electromyograph (EMG) signals generated by the user, comprising: (A) providing an interactive display to the user that displays a plurality of lists using an Exponentially Leveraged Alphanumeric String Selector (ELASS) algorithm at a first time, each list containing a set of target items, wherein each target item of a set is displayed to the user at the first time, and wherein a target item is an item displayed in a one of the plurality of lists and selectable by selection indication of the user, wherein the ELASS algorithm enables the user to locate the target item by iteratively reducing the lists by a fraction that has a numerator of one and a denominator of any integer; (B) receiving detected electromyograph (EMG) signals generated by the user responsive to the interactive display at a second time; (C) processing and converting the detected electromyograph (EMG) signals into a digital datastream; (D) analyzing the digital datastream to detect a selection indication of the user of one of the plurality of lists of displayed target items in association with the interactive display at a third time, based on analyzing a parameter associated with the electromyograph (EMG) signal values; and (E) iteratively repeating steps (A)-(D) based on a relationship of the plurality of lists of displayed target items presented to the user to select a displayed target item desired by the user, wherein the user's selection indicates one of the plurality of lists that contains the displayed target item desired by the user.
