RedLaser, a new app available via Cydia, is very cool. It's a barcode reader for the iPhone - and it works even on the 2G and 3G iPhones, without auto-focus. Reading straight from the camera feed (no need to take a photo, just hold it up to the bar code and wait a second), all 3 models of iPhone can run RedLaser. Oh, and its free... which is a nice price.
The app lets you do online price comparisons using Google's db, and view items in Amazon.com. There's all sorts of extra options available as well - and way more possible with their SDK. Imagine reading reviews on scanned books, beaming movies to your TiVo, adding milk to your grocery list... possibilities are endles.
RedLaser's magic comes from their scanner algorithm. We chatted with Jeffrey Powers, co-founder of Occipital (make of RedLaser), who said:
The bars are so blurry up close that we had to create software that is able to mathematically compensate in a way that had never been done before on the iPhone. Getting it to run fast enough for the phone was another big feat. We spent three months getting it to the level it's at now.
But for some REALLY cool stuff they're looking into using the iPhone's camera and GPS setup... check out the below video from a blog they posted a few months back... now THAT'S intense.
Keep an eye on these guys, they've got some great stuff in the works.
