Apple’s accessibility options for iOS devices make using the iPhone and iPad easier for people who are deaf or hard of hearing.
With the launch of iOS 5, we’ve taken a fresh look at the accessibility options for the iPhone. We’ve found some features that we think offer iPhone users more choice and improved functionality beyond the default settings. All of these features can be found on the new iPhone 5; the slightly-less-recent iPhone 4S has some, but not all.
Create the custom vibration patterns in the “Sounds” menu, accessed via “Settings.”
At the very bottom of the “Sounds” menu, you’ll see “Vibration Patterns.” Here you can create a new vibration pattern by tapping on the screen. Name and save it.
Next, head to your contacts, tap “Edit” on the correct contact and choose the “Vibration” option. You can add your custom creation to that contact’s profile.
(Note the Hearing Aid Mode, too!)
You’ll see a screen that looks like this. This is where you create your custom vibration before saving it. →
LED Flashing Alerts:
This is not one to use if you’re trying to conserve battery life, but is very handy if you want a visual cue for incoming calls.
In the “Accessibility” menu choose the option that sets your phone to flash alert; you’ll be notified of incoming calls, texts and notifications.
