Why accessibility?

Inclusion matters

In today’s social businesses, excluding any individual

means leaving ideas, insight and opportunities on the table.

Filtering for focus

Provide filters to create a smaller view – Ability to display a small set of rows or columns

– Ability to exclude rows or columns

– For sorted data: ability to display every nth row

Scaling for simplicity

Reduce complexity with scaling – For large or similar numbers:

– Simulates sighted scanning of large sets of numbers.

– Allows focus on the significant differences.


12/34


Interaction for insight

Provide interactive queries – Find the row or column that contains the largest or smallest number.

– Find the column that has the largest rate of change from top to bottom.

– Find the set of rows that have numbers larger than 1,000,000.

– Find the 10 rows with the largest numbers

Vocalization

The line graph has the title "Operating profits up slightly in second quarter".

Quarterly values from 1996 to 2006 are shown. The values are given in billions

of dollars. The lowest yearly values occurred in the second quarter of 1998

(26.3 billion dollars) and in the second quarter of 1996 (26.7 billion dollars) andthe highest values in the fourth quarter of 2005 (57.6 billion dollars), and in the

second quarter of 2006 (57 billion dollars).

Better navigation

QIs vocalization alone enough?

No, self discovery is key to

understanding the data! That means

user control and navigation.
