Apple says on it's website, "iOS 6 comes with even more features to make it easier for people with vision, hearing, learning, and mobility disabilities to get the most from their iOS devices. Guided Access helps students with disabilities such as autism remain on task and focused on content. It allows a parent, teacher, or administrator to limit an iOS device to one app by disabling the Home button, as well as restrict touch input on certain areas of the screen. "
In Settings, General, Accessibility, Guided Access you can set the device while in an app so that when you triple click the home button it shows you a screen that allows you to control the access points that a student has when using an app.
For example, I can disable all of the hardware buttons. That means that when using an app a student is no longer able to press out of the app using the home button, they can no longer turn off the device using the sleep button, and they can no longer change the volume.
This will eliminate one of the most frustrating parts of working with an iPad in my classroom.
As well, you can circle a part of the screen image and disable the touch function for that area. That is important when, for example, using an app that was designed for the iPhone on an iPad. I can circle the small 1x button and the student will no longer be able to toggle the size of the app during use. I can also disable areas of the screen where there is a return button or an edit feature.
What do you think? How is it working in your classroom or home?
