Don't you feel sorry for the lack of any tactile feedback? The device looks like it would suffer repeatability due to the parts moving around the fingers.

The rings don't move around very much. The flex sensor keeps each set of rings from turning around your finger, and the rings' large size limits how far they can slide up and down.

These flex sensors are quire repeatable and stable - they're more than capable of reliably detecting which fingers are bent and which fingers are relaxed, which is all we need to detect hand gestures.

Per-finger tactile feedback really isn't feasible. Haptic actuators, pneumatics, and other force-feedback stuff would make the device too cumbersome. My personal data glove has a vibrating motor on the back of my hand, which is as good as it can get.

But it's not enough to replace the traditional mouse-like input device with it.

I use an IMU (the SENtral module) in my own data glove for mouse-style input. The ring glove component featured on this page is used for gestures to select the feature. For instance, pointing with two fingers acts as a mouse, and pointing with one finger acts as a keyboard.

there is so much to do with a project like that

Hi! I tried to print for a single finger with customizer, but it always ends with an error without details.
Is there anything I can try?

As a workaround i opened it in openscad and set part = "index"; in the script to achieve this

I like your answer about making the electronics. If you get too far behind, let your customers know that I'm available, too, though my prices may be "somewhat higher"! :-)

Sooooo... where do you GET Flexpoint polyimide-coated sensors?

As of 7/3/2016, you can buy them from the manufacturer at http://www.flexpoint.com/product/bend-sensor/ .

I omitted this URL from the description in case it becomes broken in the future.

Hey,i bet you don´t know, but is there a supplier in europe? They wanna have 100 $ to ship 2 of these to germany..

Thanks! Cool project, BTW.
