hi,
my girlfriend has low vision, has worked at the lighthouse for the blind & visually impaired, and uses a screen magnifier for her computer.
after much searching, and being unable to find a screen magnifier for android, i settled for this solution.
1) rooted her optimus s (i did the same to mine. but mine is an optimus v)
for the optimus s, i had installed the zvc update, so i used this guide to do it:
[How-to] Guide to Rooting with software version LS670ZVC - Android Forums
for the optimus v, i used this guide:
[How-To] Root the LG Optimus V - Android Forums
2) changed her default fonts to BOLD APHONT--a low vision font, available here for free
APH Products: APHont A Font for Low Vision
note: the default fonts for android are in the device folder
/system/fonts/
and i replaced both
DroidSans.ttf
and
DroidSans-Bold.ttf
with APHont bold, but i made sure to rename it as "DroidSans.ttf" and "DroidSans-Bold-ttf"
*** i also kept a backup copy of those 2 fonts! ***
3) rebooted
3) changed the default font SIZE using "Font Size (for root users)"; published by i-p-tel GmbH, and available on the Android Market.
4) rebooted again
5) installed JORTE for calendar -- syncs w/ google calendar
6) now the optimus s (and my v) work much better for low-vision users!
cheers
