DESIGNING AN ERGONOMIC PROTECTIVE MASK: VISUALISATION AND SELECTION OF 3D SCANNER AND SOFTWARE

Abstract

Purpose. To substantiate the feasibility of passive 3D scanners based on modern smartphones with
appropriate software. Methodology.is based on 3D scanners and appropriate software systematization and generalization, comparative analysis; visual-analytical and information-research approaches.
Results. The active and passive scanning devices type variety with corresponding software for iOS and
Android operating systems presented, the operation principles and their use in project proposals for research
and ergonomic protective masks with various purposes development described. The using passive 3D
scanners feasibility; active and passive 3D scanners working elements placement graphic representation
provided. Proposed software selection criteria for visualizing the design solution and digitizing the mask on
the human face. Substantiated medical surgical mask made of different materials for everyday wear and as
an individual protection of respiratory organs choiced. The "Polycam" application interface presented at
various stages of visualization and a face mask 3D model creation.
Scientific novelty. Characterized, summarized, visualized and singled out the most popular software
for smartphones with Android and iOS operating systems, the "Polycam" for Android and "Scaniverse" for iOS
programs is justified based on the proposed criteria and features are choiced.
Practical significance. Proposed approaches for the new design solutions, for ergonomic protective
masks varieties creation, passive 3D scanners based on smartphones with appropriate software for practical
use. Based on the analysis of the studies, the device and software recommendations use for visualization of personal respiratory protective equipment are provided. The 3D scanning effectiveness of the human body and its specific volumes (planes) researched and can be useful for clothing designers of various purposes, game designers (3D artists, multimedia character artists), IT specialists, etc.
