just pen / Writing tool

The “just-pen” solves problems of users with hand dysfunctions as lack to 4 fingers at a hand and also with the limited hand activity caused e.g. by wrist syndrome.
Writing “by finger” seems to be the simplest and most intuitive method of writing, therefore I based on it my examinations. Thanks to essential ergonomic analyses I got structure which allows to use product just by one finger.Moreover, sinew’s tension with this method is smaller than with conventional methods. The functional solution is based on three fulcra of the finger. The tool is using a standard refill. It’s more accessible and cheaper.The functional model is made in the RP.
