Data visualisation is vital to modern business, allowing complex metrics to be displayed real time and via a medium which some might feel easier to interpret than pure text or numeric values.

Individuals want the ability to display metrics relevant to their lifestyle, working patterns and health visually; hence the development of Nike's running monitors, time monitoring and task tracking software, services like Patients Like Me, apps like Capzule, and sites like Quantified Self are but a few examples.

Smarter dashboarding in vehicles to monitor your driving style, home automation which monitors your personal energy usage and visual diet tracking are just a few areas in which personal metrics and data visualisation converge and could and in some cases already do provide value.

Patients Like Me
Our goal is to enable people to share information that can improve the lives of patients diagnosed with life-changing diseases. To make this happen, we've created a platform for collecting and sharing real world, outcome-based patient data (patientslikeme.com) and are establishing data-sharing partnerships with doctors, pharmaceutical and medical device companies, research organizations, and non-profits. Contact us if you're interested in working together to achieve our goals.

Quantified Self
"Quantified Self is a collaboration of users and tool makers who share an interest in self knowledge through self-tracking. We exchange information about our personal projects, the tools we use, tips we've gleaned, lessons we've learned here at our group blog. Kevin Kelly and Gary Wolf maintain and moderate the blog, but our list of authors also includes Alexandra Carmichael, Joe Betts-Lacroix, Steve Dean, Robin Barooah, Mike Kirkwood, Ian Li, Rajiv Mehta, and Chris Finlay."
