Incorporating Tactile Cues into Human‐Centered Virtual Product Design

Abstract

This study introduces a high‐fidelity tactile feedback mechanism to capture ergonomics attributes of users inside virtual product development cycle. The research question posed regards whether the tactile feedback mechanism in virtual experiment proposes high fidelity of ergonomics results when compared to physical experiment outcomes. This question was evaluated through an objective and a subjective study. Objective study was composed of an ergonomics product assessment experiment, where two different cart designs (a commercial cart and a prototype model) were evaluated for ergonomic adequacy (L4/L5 compression forces). Subjective evaluation was consisted of a questionnaire to assess subjects' preferences regarding which cart model they preferred in three different design categories; maneuverability, accessibility, and ergonomics. Results showed that tactile feedback mechanism was able to replicate the physical test conditions in virtual environment with high fidelity, and prototype cart model received higher mean ratings when compared to commercial cart model in each design category.

How Does Virtual Reality (Vr) Facilitate Design? A Review of Vr Usage in Early-Stage Engineering Design

“…Research Questions Key takeaway -Can a tactile feedback mechanism simulate outcomes of physical experiment outcomes? (Demirel and Duffy, 2017) -What are the differences in designers' spatial perception in VR and non-VR environments? (Kato, 2019;Lukačević et al, 2020) VR can provide an equivalent or superior experience of perceiving and evaluating designs.…”

O Uso da Captura de Movimentos no Desenvolvimento de Produtos: um estudo focado nas tecnologias e aplicações

“…Nele é apresentado a abordagem/objetivo do estudo, bem como o tipo de equipamento tecnológico (captura de movimentos) utilizado. De acordo com o quadro 3, é possível perceber que os estudos concentram-se principalmente na área da Ergonomia, e salienta-se as análises ergonômicas para o desenvolvimento de produtos/sistemas/serviços (DEMIREL; DUFFY, 2017;LEE et al, 2017;LI;NOH, 2016;ESPITIA-CONTRERAS;SANCHEZ-CAIMAN;URIBE-QUEVEDO, 2014;JI;JUN, 2014;SALVALAIO, 2012), bem como no processo de concepção de novos produtos (JUN, 2015;SOLOMON, 2015;FERNANDES, 2014;MA et al, 2013;HARIH;ČRETNIK, 2013), como também para a análise e avaliação de projetos (OYEKAN et al, 2017;CHOI;LEE, 2015;VELAZ et al, 2014;NOH, 2014;QING et al, 2013;OSTERLUND;LAWRENCE, 2012).…”

“…Com base na identificação dos sistemas de captura de movimentos, destaca-se o sistema Óptico presente em 6 estudos (DEMIREL; DUFFY, 2017;LEE et al, 2017;CHOI;LEE, 2015;QING et al, 2013;MA et al, 2013;OSTERLUND;LAWRENCE, 2012;)…”
