The device uses two servos for controlling the laser: one for X-axis control and the other for Y-axis control. The controls are executed from an Adafruit Itsy Bitsy M4 Express microcontroller.

Artemis is an eyeglass-mounted device that can be configured to locate a specific type of object, or a person. When the target is found, Artemis will track it with a laser.
An eyeglass-mounted camera streams images to a Jetson AGX Xavier. An SSD300 model is used for object localization within these images. When the object of interest has been found, a laser diode is turned on.
A servo is also mounted on the eyeglasses for X-axis control of the laser. A second servo is mounted on top of the first, at a 90 degree angle, to give Y-axis control. The laser is mounted on the second servo.
Images are thresholded in OpenCV to determine the location of the laser pointer. With the location of the object, and also the laser, now determined it is possible to adjust the servos to place the laser over the object of interest.

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.
