Ortho is a device that measures the distance and position of a person's body when placed on a desk or other surface. The device detects movement through vertical elements connected to a hinge that rotates in a circular motion on an axis. A stepper motor drives the rotation, and each element is positioned at a different distance from the center of the circle, creating a wave-like sensation.

In addition, a hidden LED strip in the center of the device provides different lighting conditions to indicate incorrect positioning of the user's foot. The device uses a camera to read points on the human body and the distance from the computer screen to provide this information to the user through color-coded alerts.

The user experience is straightforward. Ortho automatically detects the distance between the user and the device, eliminating the need for the user to adjust it manually. Additionally, Ortho's movement is smooth and fluid, creating a pleasant experience for the user.
