Finding ways to visualize wearable data is sometimes a tough challenge. How exactly do yo visualize physical attributes when the meaning of those numbers are different for each person? Then there are the ethical considerations of what should you be displaying and where you should display it. So this article about displaying stress levels for everyone to see seems more concerning than intriguing (see also the video above about bio-wearables). Anyone that has used a stress monitoring device of some kind knows they are not always accurate. But even when they are, would you really want that information broadcast to people around you? Maybe you would, maybe you wouldn't - we are probably all different. But there is also the very real concern of people that could see you are stressed and take advantage of that. Which I realize already happens without technology, but the concern over what data is being collected and who it is available to is a huge one to grapple with.
