This kind of thing has been done already, a lot. What would make your gloves different to the tech that's already out there? A lot of blind people use cains that they hold in their hands, so gloves might not be the best thing to wear. Here's an article about gloves for the blind. http://www.dailymail.co.uk/sciencetech/article-2951187/Soon-HANDS-Vibrating-glove-uses-ultrasound-help-blind-navigate-surroundings.html How much would these gloves cost? TThere's a product here in the UK that you hold and it does what you've described but it uses sound waves I think. Here's a product that does this http://www.sightandsound.co.uk/buzzclip.html

Most devices that use sonar sensors have been either glasses, or the device it attached to the cane. Although there is one that can clip onto clothing, too.

While gloves should be an good placement point (you can point your hand at things to check distance and it can be more intuitive), your hands may not be free. If it was glasses mounted, it is easier to look at the object.
