The app sometimes goes on on a rant to read a longer piece of text.
I need to make a way to stop reading of this huge chunk.
I was thinking of a UI that:
a) the button has to be pressed to read, pauses on release
b) there is a start / stop

The reason for the need to be pressed constantly is because my grandpa will "zone out" when he does not understand.
I need to make it easy for him to communicate that he does not understand.

The app is detecting "blocks" of texts which consists of paragraphs and words.
I think the list of reading has to show the more granular - line by line transcription

The app relies on capturing data from the built-in camera.
But that requires you to jump through the hoops of

• 'select the camera app'
• press ok
• confirm if you want this photo

This is too much and my grandpa looses patience

After testing on Galaxy Tab 10.1, the image is automatically rotated.
I suspect the issue is that Samsung's camera app is only doing 1 rotation and puts EXIF data to appropriataly display the image.
The base64 version of the image is not respecting this EXIF data.
Possible solutions:
a) Rotate
b) Stop using built-in camera
