Smartphone Integration and Core Mechanics

What happens here

A smartphone (an iPhone is shown) is attached to a dedicated mount on the handle of the measuring wheel. The presenter explains that the device operates by combining the physical measurement from the wheel's rotation with the spatial data from the phone's internal gyroscope. All calculations and data processing are handled by a specialized app installed on the smartphone, which simplifies the process of obtaining accurate measurements.

Goal: This step demonstrates how a smartphone attaches to the measuring wheel and explains that the device uses both the wheel's rotation and the phone's gyroscope for precise measurements and calculations via a dedicated app.
