My Smarter Essex follow-up questions
Thank you to everyone who made the My Smarter Essex event on 6 October 2016 such a fantastic success.
The level of interest, enthusiasm and engagement from all parties (especially the student audience) was overwhelming and we now have a vast wealth of comments, questions and issues to pore over!
In the coming months we will discuss the big issues that face us as we move towards a smarter Essex. In the meantime, we'd like to answer some of the more specific questions submitted during the presentations:
- How does the heart rate monitor app (Cardio Buddy) work?
- What is the relative efficiency of the lighting technologies shown?
- What is "Bluejacking"?
- Where do I buy a Cozfest t-shirt?
Follow the links or read on for answers...
As blood flows in the capillaries close to your skin, tiny colour variations (imperceptible to the eye) occur as the amount of oxygenated ("red") blood varies with each heartbeat. Cardio Buddy uses your phone camera to detect these colour variations in the skin on your face. By analysing these it can determine your heart rate.
You can download and try out the app yourself here: http://download.cnet.com/.
Please see Lighting efficiency study.
Bluejacking, and the related (and more serious) activity of Bluesnarfing, involve hacking devices over Bluetooth.

Thank you to everyone who submitted questions/comments, and please do stay and/or get involved with this very exciting project. We will be setting up a portal here for people to get involved and to contribute their ideas: please keep an eye out for this. We look forward to working with you!
