Audio Rendering of Web Pages -Problems There has been much work to offer an audio
rendering of web pages to blind users, but even the best audio rendering engines still suffer from some intrinsic limitations such as: sequential navigation long processing time difficult navigation within a long page or across
web pages audio rendering only works when HTML is well-
formed
Haptic Rendering of Web Pages -Basic Idea
Each HTML component
is being transformed into a
Hapget. Hapget = 3D widget +
haptic feedback
Haptic Rendering of Web Pages - Advantages The user may freely navigate within a scene
the haptic pointer may asynchronously move from an object to another - no sequence is imposed
The time required to switch from one screen object to another object may be reduced at the price of a haptic exploration of the scene
The blind users can have a perception of the structure of the virtual environment, in our case the 3D corresponding of a web page, that is very close to the real one it cannot be exactly the same because 3D rendering puts some
limitations in positioning It is essential not only to give blind people raw information but
give them the opportunity to navigate through the internet in a way that makes navigation really interesting.

Haptic extension to UsiXML CUI model
The new extension adds not just a new interaction type, the haptic, but also the 3-dimensional (3D) graphical representation.
Each haptic component (”hapget”) has unique characteristics, such as: shape surface properties appearance a set of effects that are supported by the haptic device, including:
buzzEffect constraintEffect inertialEffect

Guidelines
The hapgets should be visually distinctive enough from each other to avoid any confusion.
There is a need to supplement the visual distinction by other means.
The hapgets should have colors that are distinctive enough from each other. The different colors should be radically different when they are turned into grayscale so as to support distinctiveness for color-blinded users.
The hapgets should be haptically distinctive enough from each other.
Each hapget should be perceivable enough per se. Otherwise, the haptic feedback is just ignored and do not provoke any emotional output.
Conclusion and Future work

graphical representation so as the interaction
