Project Description

"This blog is updated by the JISC funded G3 Project (#jisc3g) team. We are building an framework for teaching and communicating relevant geographic concepts and data to learners from outside the world of geography and GIS. We think this blog will be of particular interest to those working or teaching in HE and FE and those interested in teaching and learning and e-learning."

Child of Ten Standard of User Interface Design

A useful benchmark in user interface design is the Child of Ten standard. This means that a child of ten should be able to learn to do something useful with the system within 10 minutes. This indicates that a system is “easy to use”. In 1998 Al Gore discussed this in the context of GIS and digital globes as cited by Goodchild his paper “the Use Case of Digital Earth” in 2008.

I do not know if this has actually been validated for digital globes such as NASA World Wind or GoogleEarth but from personal experience I am absolutely certain they are easier to use, easier to learn and easier to remember the functionality than proprietary desktop GIS.

In this project we aim to develop a useful and usable GeoWeb application for non experts and so this benchmark could be incorporated into the testing and development phase – can non-experts learn to do something in our application within 10 minutes? Something to consider.....


  1. A good user interface facilitates the website with a smooth navigation and functionality from the users' perspective. It helps to create a system that is both usable and capable of adapting to the changing user needs.
