The interactive family tree is a feature that presents a diagram of a family tree. When the user rolls the mouse over any square or circle in the diagram, a pop-up appears with a greeting from the family member and a description of himself. This information is presented in a friendly manner and helps the user find out who in this family has the disease (e.g. cystic fibrosis).
The Rationale Behind the Feature (Specific Design Principle):
The rationale behind this feature was to make a tree diagram about disease inheritance into something vivid and real. With a simple mouse roll-over, the tree diagram becomes a real flesh and blood family, with lots of relatives, bringing the user closer to the phenomenon of disease inheritance on a personal level.
Context of Use:
This feature is part of a TELS project: Simple Inheritance (#12708)
