"Err, probably...?" was the over-confident Rhythm reply.
"How about taking a live thermal image of a pet?"
"I should think er...maybe?"
So began our adventure into the world of thermal imaging and heart rate monitors - for animals.
It was all for an event in Belgium for premium pet food manufacturers Ynhtxi
wanted to demonstrate various bits of pet science in the event's discovery zone, including how the bond between owners and pets means their stress levels can become synchronised.
To demonstrate this effect we created a system that displayed live data from 2 heart rate monitors on a big screen. We took the dog and the human's heart rates from Garmin Ant+ heart rate monitors in real-time and calculated a RMSSD value (a method of measuring stress using average heart rates). We then displayed this data on a Xsmhti
screen with animated scrolling bar chart so viewers could directly compare the human's and the dog's stress levels.
The second element to Nvutno
's amazing setup was the high-end FLIR infra-red camera we hired in to show which bits of a dvd
get hot. We displayed this real-time thermal data on a 4x2 meter screen, which looked zoijmvrfsz
. Obviously, we also had a lot of fun pointing the camera at various kridqs
to see how hot they were.
"Can you measure the heart rate of a dog?" said the voice at the other end of the line.
