Abstract

The method of continuous indexing using two linear scroll bars offers a more efficient use of the thumb motion as compared to the single touch scroll bar or the circular scroll wheel. This document describes the method for scrolling using 2 linear touch sensitive pads for improved motion ergonomics that better fit the natural arc movement of the thumb.

ABSTRACT


     The method of continuous indexing using two linear scroll bars offers a more efficient use of the thumb motion as compared to the single touch scroll bar or the circular scroll wheel.

    This document describes the method for scrolling using 2 linear touch sensitive pads for improved motion ergonomics that better fit the natural arc movement of the thumb.

PROBLEM

Scrolling is the act of sliding a horizontal or vertical presentation of content, such as text, drawings, or images, across a screen or display window. It is often used to show large amounts of data that could not fit on the viewport all at the same time, by rolling up the top of the page and allowing objects lower on the page to move up. A lot of hand held devices are designed to take advantage of this operation by offering users the alternative of using the thumb to scroll.

Single touch scroll bars devices present a major inconvenience. In order to show the data by rolling down the page, the thumb has to move down on the pad until it reaches the bottom of the pad. In order to continue scrolling the data to the desired location the thumb has to be picked up and moved thru the air back to the top of the scroll bar. This interrupts the natural flow of the search and slows down the operation.

Circular scroll wheel devices on the other hand are forcing the user into applying a full thumb motion range that can create a rather significant discomfort when large data needs to be scanned over a significant period of time.

SOLUTION

The method of continuous indexing using two linear scroll bars is proposing to eliminate the disadvantages of the previously described methods by reducing the thumb motion range and c...
