Abstract

Augmented/mixed reality has many potential applications in the medical field. We sought to determine whether a mixed reality ruler capable of measuring the distance between a user’s fingers is sufficiently accurate for making measurements during clinical procedures. A custom virtual ruler application was deployed to the Microsoft HoloLens headset. The custom app calculates the linear distance between the user's fingers. The accuracy of the virtual ruler was tested under various conditions including room brightness and background textures. A set of wires of known length were measured with the virtual ruler. The accuracy of the virtual ruler was dependent on the measurement length. Measurements between 2-15 cm had an error less than 0.5 cm, between 15-30 cm had an error less than 1 cm, and between 30-50 cm had an error less than 1.6 cm. A mixed reality based hand-ruler is sufficiently accurate for making measurements during maximally sterile clinical procedures.
