Interventions

Smartphone-Based 3D Body Scanning DIAGNOSTIC_TEST

Participants undergo anthropometric assessment using three different measurement methods: traditional anthropometric measurements, smartphone-based 3D body scanning applications, and a 4D stereophotogrammetry system. Traditional measurements include the use of a measuring tape, stadiometer, and weight scale. Smartphone-based measurements are performed using the 3D Measure Me and MeThreeSixty applications on a smartphone device. The 4D stereophotogrammetry system is used as the reference scanning method to generate a full-body digital avatar. All measurements are collected during a single study visit to evaluate the validity, reliability, and accuracy of the different body measurement techniques in healthy adults.
