Today, everyone is excited about transparent OLED panels, but where does the love for the classic Nokia 5110 LCD come from? As prolific [Nick Bild] In his latest work, All you have to do is peel off the backing of the late 90s display, and you can buy a transparent cyberpunk screen for a few dollars.
under these circumstances, [Nick] The modified display has been connected to a pair of frames and connected to the ESP-EYE development board powered by ESP32 and the OV2640 camera module using the Adafruit QT Py microcontroller. This allows him to detect the QR code in the wearer’s field of view and run the TensorFlow Lite neural network directly on the hardware. Power is provided by a 2000 mAh lithium polymer battery running through Adafruit PowerBoost 500.
The project aims to provide medical professionals with augmented reality reminders to use QR codes to find patient and drug information. Now, neural networks are used to detect when the wearer washes their hands, but obviously the training model can be switched to different things as needed. By combining these sources of information, wearable devices can do things, such as warning the doctor if the patient is allergic to the drug they are currently taking.
Related information and warnings are displayed on the Nokia LCD screen, which is far enough away from the eyes so that the user can really read the text; an important design consideration [Zach Freedman] A few weeks ago, he performed a demonstration with his (deliberately) illegible wearable display.This does make the design a bit… awkward, but at least you don’t have to worry about cutting the optics by hand
