Light sensors on wearables struggle with dark skin and obesity #WearableWednesday
It is vital to consider all bodies when developing any wearable device. A new study brings to light some major problems in current tech. Via The Verge:
Light sensors used to track heart rate in wearable devices like the Apple Watch Series 5 and the Fitbit Versa 2 don’t work as well on darker skin or people with obesity, according to modeling done in a new study.
That’s a problem for features currently built into devices — but it’s also a bad sign for efforts to use light sensors for new applications in wearables, like monitoring blood pressure, says study author Jessica Ramella-Roman, an associate professor studying bioimaging sensors at Florida International University.
Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
