A Human-Centered Design Procedure for Conceptualization Using Virtual Reality Prototyping Applied in an Inflight Lavatory

For designing large-scale products like an airplane, engaging end-users in the concept phase is difficult. However, early user evaluation is important to choose the path which fits the user’s needs best. In particular, comfort-related assessments are difficult to conduct with digital models that are shown on a desktop PC application. Digital...

Grabs and Cohesive Bulk Solids: Virtual prototyping using a validated co-simulation

Due to the high demand of iron ore products in the steel industry, they have the largest share in dry bulk trading per year, above coal and grains. Approximately 9000 Cape-size bulk carriers with capacities up to 400 000 tonnes (DWT) transport the annual demand of iron ore to destination ports. Grabs are employed extensively to unload iron ore...

Prototyping in social VR: Anticipate the unanticipated outcomes of interactions between AI-powered solutions and users.

Interactions of users with AI powered solutions (AIPS) have the potential to affect collective behaviours and amplify unanticipated outcomes. Product developers, organisations, and companies are increasingly being expected to take responsibility for the unanticipated outcomes of their products. In this paper we explore a proactive approach to...

Virtual prototyping of grabs: Co-simulations of discrete element and rigid body models

This dissertation has investigated whether a combination of DEM and MBD can be used for a reliable and accurate environment for predicting grab unloading performance. A grab is a type of bulk material handling equipment used for unloading materials such as coal and iron ore from vessel to shore. Both a grab and iron ore pellets have been...

Clutter and Realism: An investigation on the effect of clutter on the perceived realism of 3d computer generated renderings

Current "Philips" practices include development of physical environments in which luminaires can be tested with the user. However "Philips" is also interested in virtual prototyping and thus is turning towards identifying a number of features in 3d environments which influence the human perception of realism. This study utilizes traditional...

Virtual Prototyping in Laundry Products: Development of a Maxdiff and Conjoint Interface

The aim of this research is to find out how Fast Moving Consumer Goods companies can perform an effective and fast market research to investigate what excites consumers most in a laundry detergent product and what trade?offs are made between price and product attributes. A quantitative research method is developed for the laundry detergent...

Theoretical underpinning and prototype implementation of scenario bundle-based logical control for simulation of human–artifact interaction

This article presents a new methodology that enables designers to include in simulations not only the physics aspects of artifact behavior, but also human actions. The motivation for this research came from the fact that none of the conventional approaches to engineering simulations includes manipulative control of products by users as foreseen...

Simulating the use of products: Applying the nucleus paradigm to resource-integrated virtual interaction models

We introduce a methodology for modelling and simulating fully virtual human-artefact systems, aiming to resolve two issues in virtual prototyping: (i) integration of distinct modelling and simulation approaches, and (ii) extending the deployability of simulations towards conceptual design. We are going to offer designers a new way of...
