looking for an app that can detect obstacles for the blind

Hi does anyone know of any apps that can use the iphone video to detect obstacles for the blind. I am looking for one that would vibrate a bit like a car parking sensor ?

thanks

Sensors like those in cars use more than just video for sensing proximity to objects - as far as I know, there's no apps... and further, no 3rd party add-on devices/sensors to make it possible to do on an iPhone.
