Using SAS
The instruction provided here are from the SAS Graphics Accelerator Product Page.
SAS Graphics Accelerator enables users with blindness to perceive many types of charts and graphs using ear buds and a standard computer keyboard. Each data element in a chart or graph is represented by a sound. The pitch of the sound indicates position on the Y axis. Position on the X axis is communicated using the stereo effect between the left and right speakers or ear buds.
To explore a chart or graph:
- Open Google Chrome.
- Install SAS Graphics Accelerator for Google Chrome from the Chrome Web Store.
- Open a chart or graph page and activate the Accelerate button.
- Press G to cycle between data groups displayed on the graph.
- Press V until you hear “Explore Mode”, then press the left/right arrow keys to explore point by point.
- Press V until you hear “Scan Mode”, then press the left/right arrow keys to play the entire chart or graph.
- Press D to change speed.
- If the chart or graph contains grouped data, press G to change groups.
- Press C to cycle through settings for spoken number and text values (verbose vs. terse).
- Press S to play multiple groups as a chord or melody.
- Press H for additional commands.
