Graphical representation of projective analysis of the requirements used in the process design of assistive products

Abstract

Graphic representation is a little explored technique in the development of assistive products, despite being helpful in the visualization of conceptual aspects, which are then made tangible. This improves the understanding of the process phases by the whole team, which includes practitioners from different areas. Thus, the characterization of graphic symbols used in assistive technology development processes are presented. A literature review was carried out to select: graphic symbols and pictorial images used in health care area; and the design of new proposed methods for assistive products that had some graphic representantion of its processes. From this point the authors developed a preliminar hybrid characterization model based on symbolization of graphical representations (verbal, schematic, and pictorial) and approaches for pictogram design (geons, silhouettes and observation). The results of the characterization were discussed using as reference the hybrid model and the gaps. The assessment showed low use of graphic symbols for design processes representations, even when the authors were designers.
