Abstract

Disclosed is a user interface method that allows for quick, efficient exploration and usage of user interfaces by people who cannot see. The interface method is a circular direct-selection interface where many user interface elements are arranged around the edges of a touch panel or touch screen. This makes a circular list of elements that users can touch to get speech output and then activate when they find the desired element. This arrangement can be explored easily but also allows users to efficiently and directly select elements on familiar interfaces.

Introduction to the problem

Using a touchscreen device is challenging for people with low
and no vision because they cannot easily see any of the controls
or other elements on the screen. Currently, two general
categories of accessible interfaces for touchscreen devices have
been developed to allow people to get speech output and
activate elements: navigation and direct exploration/selection.

With a navigation interface, a person must move or navigate
through elements one at a time. The navigation paradigm is
frequently used but is inherently inefficient because users must
navigate past options they do not want until they finally get to
an element with which they want to interact. The user often spends more time navigating than doing what he or she really wants to do with the interface. With direct exploration and selection, a person touches elements on the screen to hear them. When the desired element is found, it can be activated. One major problem with this method of activation is that a user has to search for elements by touch on a featureless screen. With an unfamiliar interface, users may have difficulty finding what they want. This difficulty is exacerbated with large screen sizes, with small elements, or with widely spaced elements.

The current invention, a circular direct-selection mode, is a method that allows for direct exploration and selection of an interface in a common, systematic pattern (Figure 1). It allows for more efficient use for both novel interfaces and interfaces with which people are familiar.
