I gave my good friend a Lumia 925 for his birthday about a month ago. He has a mild but noticeable tremor, especially when performing fine motor tasks. He has been doing okay learning how to use his first smartphone. But the difficulty he has in controlling the UI is getting in the way of really mastering the device.
Are there any ease of access features or add-on packages that would help him?
One thought I have is that if screen touch sensitivity can be reduced, it would prevent situations where the phone detects a fingertip touch, even though he was really hesitating and not trying to touch the screen.
Another idea is to configure the detection thresholds for (1) speed of swipes and (2) duration of touch-and-hold gestures.
I wonder if Windows Phone OS even allows a third party developer to interact with the screen input vectors like this. The developer's code would be inserted between the screen input events and any running application. That sounds like a security risk that a secure system like WP simply would not allow.
