Method and System for Increasing Accessibility of Contents on a Screen

Disclosed is a method and system for increasing accessibility of contents on a screen. A perspective distortion is applied to the contents to enable a user to efficiently interact with the content using a single finger.

The method and system disclosed herein enables a user to place a mobile device in an easy-reach mode. In the easy-reach mode, contents on the screen of the mobile device are re-distributed by applying a perspective transformation to the contents as illustrated in Fig. 1. The perspective transformation may be applied based on an accessibility range provided by the user and therefore tailored to the user.

Figure 1

The arc in Fig. 1 illustrates an accessibility range of a typical right-handed user using one finger (for example, using thumb). A similar screen configuration is possible for left-handed users as well.

Application of perspective distortion results in ambiguity with regards to axes along which flick gestures are to be made to scroll through the contents. Accordingly, flick gestures in a downward direction relative to the axes of the device or along a main axis of the transformed content are interpreted as scroll-down events as illustrated in Fig. 2. Similarly flick gestures in a horizontal direction may also be interpreted.
