Accessible View: An ARIA for web search
The Accessible View experiment is another step toward making our search results more accessible for everyone. In July 2006, we launched Accessible Search on Google Labs, where the goal was to help visually impaired users find content that worked well with adaptive technologies. We continue to refine and tune the ranking on Accessible Search. And with Accessible View, users can easily toggle between regular Google search results and Accessible Search results by using the 'A' and 'W' keys.
When we designed the Accessible View interface, we first looked at how people used screen readers and other adaptive technologies when performing standard search-related tasks. We then asked how many of these actions we could eliminate to speed up the search process. The result: a set of keyboard shortcuts for effectively navigating the results page, and to arrange for the user's adaptive technology to speak the right information during navigation.
We've also added a magnification lens that highlights the user's selected search result. Since launching Accessible Search, one of the most requested features has been support for low-vision users. While implementing the keyboard navigation described here, we incorporated the magnification lens first introduced by Google Reader.
Bringing it all together, we implemented keyboard shortcuts that extend what was originally pioneered by the keyboard shortcuts experiment. These shortcuts help users navigate through different parts of the results page with a minimal number of keystrokes. The left and right arrows cycle through the various categories of items on the page (e.g., results, ads, or search refinements), and the up and down arrow keys move through the current category. Power users can leave their hands on the home row by using the h, j, k, and l keys. In addition, we enable an infinite stream of results viewed through the n and p keys — so you can move through the results without getting disoriented by a page refresh after the first 10 results.
Key | Behavior |
j/k | next/previous result |
n/p | next/previous result, scroll if necessary |
enter | open current result |
up/down | next/previous result |
left/right | switch categories (results, ads, refinements) |
a | jump to ads |
A | switch to Accessible Search results |
W | switch to default Google results |
r | jump to related searches |
