[Blindmath] graphs on iOS (was: SAGE?)

Hi Alex,

Believe or not, I'm also trying to get such an app on the store.
I'm a huge believer in data sonification and love MathTrax. In fact I use MathTrax's descriptive feature to understand patterns on financial charts that I use for my trading in the stock market.

A major advantage of iOS devices and VoiceOver is that when you tap on a point, VoiceOver will announce the exact value/ label associated with that point. This has never been available in the traditional PC environment.
You can find this feature in the preinstalled stock application on your device.

Another advantage is that iPhone (not other iOS devices) has a vibrating motor that can be used in conjunction with the previously mentioned feature to provide additional tactile feedback.

I'm trying to look for researchers willing to work with the iOS environment to come up with a fully accessible interactive charting app.

Regards
