A mixed reality tool for end-users participation in early creative design tasks

Abstract

While Mixed Prototyping has proved to be e↵ective for the assessment of prototypes, this research aims to explore the use of Mixed Prototyping for the generation of early prototypes. To satisfy end-user's needs, new products need to be designed with an early integration of end-user requirements. An e cient way to achieve this is to directly integrate the end-users in the design process and give them an intelligible and interactive tool to perform specific design tasks. Current interactive tools to integrate end-users in the design process provide either a high level of immersion (e.g. CAVE) or a high level of control over the virtual prototype (e.g. Configurators). We designed a new Mixed Reality design tool which simultaneously allows end-users to be immersed in a virtual environment (immersion) and to interact with a virtual prototype and to modify it (control), resulting in e↵ective end user-interactions. In two design use-case scenarios, we assessed the enduser experience and satisfaction while using the tool and we also evaluated the impact of the tool on the creative process and the design outcomes. The findings show that, when users are provided with a tool that allows to directly perform design tasks and modify a virtual prototype, as compared to when they have no control, they are more engaged in the design tasks, more satisfied with the design process and they produce more creative outcomes.

Prototyping adaptive systems in smart environments using virtual reality

“…In this case, the VE is used to validate the system before its implementation in real robotic cells. Furthermore, the VE is used to evaluate the end-user experience and satisfaction while using Ask for a support Activate an interactive guide that supports the user step-by-step different tool [51]. A similar approach can be exploited to preliminary test adaptive domestic systems, but no work has been reported in the literature.…”

The Role of a Web Portal to Facilitate Higher Learning Institutions Students’ Field Attachment in Tanzania

“…The study employed collaborative user-centered development under Scrum framework to minimize errors and ensure greater usability (Maurya, Arai, Moriya, Arrighi, & Mougenot, 2019). Scrum development approach allowed regular inspection of progress and acceptance testing of each increment (Karabulut & Ergun, 2018).…”

Enabling Designers to Generate Concepts of Interactive Product Behaviours: A Mixed Reality Design Approach

“…We implemented the proposed MR design tools in 3 parts: VR environment, TUI, and workstation hardware, based on work of Maurya et.al (Maurya et al, 2019). Virtual scenarios were developed using Unity3D software.…”
