Example text

Therefore 63 Flash objects in 47 pages were suitable for this survey. Overall, this shows that the windowless mode is used frequently and screen readers are losing the information in more than half of the Flash objects. 2. The fraction of buttons without alternative texts Of the 63 Flash objects, 35 of them contained a total of 505 buttons, and 53% (268 buttons) did not have alternative text. Figure 2 shows the distribution of the buttons with alternative text for each Flash object. The distribution is rather bimodal, with unusually large numbers of objects at the two extremes.

The proxy embeds a component into each Flash object to check for the existence of _accProps or _accImpl. If they exist, the component displays a message on the screen. The detailed calculations are as follows: 1. Recognizing windowless mode The survey tool checks “window handle” and “class name” to recognize windowless-mode Flash Player objects. A window-mode Flash object in Internet Explorer exposes an MSAA object, which contains a valid window handle with the class name "MacromediaFlashPlayerActiveX".

When the remote evaluation is carried out, the prototypes can be freely distributed as beta versions to be evaluated by all users interested in the application. 3 State of the Art in Remote Testing Next, we include the main features of some of the most important data gathering tools applied to navigability testing. 30 M.
