Have you ever seen a cat hiding under a bed with its tail sticking out, revealing its location? Or a child hiding behind a pole, unaware that its body is showing? Without our knowledge, we often give ourselves away. What is the stuff that we’re often unaware of that reveals our emotions, our identities, and our invisible activities? In this program we’ll start by aggregating data about ourselves. From there, we’ll use sensors to collect “biometric data” to look at how physical cues give us away. When do we sweat the most? And is there a difference between the sweat we produce from exertion or anxiety? Could we use this to detect lies? What about heart rate? How could we create a heart monitor to investigate our emotions? We will collect biometric data using DIY and on-the-cheap methods and tools. We’ll engage with ideas around physiology, anatomy, electronic sensing, and how we use proxies to see what’s happening inside of us.
