With VisionAssist, the future of electronic video magnification comes into focus. This iOS app converts the camera and screen of any iPad, iPhone, or iPod touch into a portable CCTV.
What impressed me was how many functions found on dedicated devices such as the $495 Pebble -- e.g. "freeze frame" and high-contrast viewing options -- Slinkyware engineered into an app costing just $5.99.
VisionAssist was the first app I downloaded to my iPod touch. Despite an inferior camera compared with the iPhone 4S, and iPad, the translation of key features to the iOS platform tells me the era of handheld and desktop video magnifiers may be over.
So many blind and visually impaired people have already migrated many assistive technologies -- such as book readers, GPS, and color identifiers -- to their iPhone. There's something freeing about having fewer dedicated devices to carry around, especially when they cost so little.
